How Your Oral Biome Influences Your Overall Health

Inline_Oral_BiomeIn response to my post on oral health a few weeks ago, one reader offered a comment about the oral biome, and it’s a worthy follow-up, I’d say.

The human oral cavity is home to hundreds of microorganisms. Latest estimates place the number of bacterial species in your mouth at close to 700, with the odd fungus, protozoa and even virus thrown in for good measure. This oral microbiome isn’t a whole lot different than that of our gut, but where things get interesting is when we consider the diverse range of habitats within the mouth: teeth, tongue, cheeks, gums, tonsils. All provide different living conditions for those microorganisms that colonize them, but that diversity of habitats also encourages a diversity of species.

And it’s fair to say that human microbiological research as a whole began with the mouth. In 1683, Dutch businessman and self-taught scientist Antoni van Leeuwenhoek scraped off a bit of plaque from his teeth, slotted it under his home-made microscope, and was the first person ever to physically see his own bacteria. Suddenly, one’s body was no longer wholly one’s own.

Since then, the study of oral microbiology has waxed and waned, but in recent years the topic has been a hotbed of activity in the scientific sphere. While the health of your gut flora is important, it’s becoming increasingly apparent that so, too, is the health of your mouth flora.

What Is the Function of the Oral Microbiome?

By now, you’ve firmly wrapped your head around the importance of homeostasis. As hocus-pocus as it sounds, achieving equilibrium in the body is critical to maintaining robust health.

This Zen-like mantra applies whole-heartedly to the oral microbiome. In a healthy mouth, your microflora and their by-products play an essential role in the salivary immune system, bravely warding off pathogenic invasion down your throat and into your nether regions. These microscopic communities also aid in digestion, protect your teeth against acidic foods and substances, and process vitamins that are critical to our general health.

The little guys in your mouth can even play a role in odors. That glass of red smell a bit off? It could be that your oral community is haywire, rather than a crappy cork or a blast of sulfites.

And the party doesn’t end in your mouth. Research published a couple of years ago demonstrated that the small microbial population of the human lungs are populated, at least in large part, by the same microbiota occupying our mouth. It seems that the lungs, and presumably other parts of the body, “borrow” bacteria from the mouth to ensure they’re meeting their biological quota. Studies have even shown that the placental microbiome more closely resembles that of the mouth than any other part of the body. In this way, the mouth acts as a biodiversity reservoir for the rest of the body.

When Your Oral Environment Is “Off”

Back in 1929, an article published in the Journal of the American Dental Association entitled “Animal Parasites of the Mouth” first suggested that these might directly contribute to dental disease. Of those dental diseases, periodontal disease and gingivitis are the big players, and in fact contribute to the second most common human infection: dental cavities. (hint: the common cold is, not surprisingly, takes top billing).

Slowly, our understanding of the dynamics of oral disease is improving. After years of research, scientists can now use changes in the oral microbiome to predict the onset of dental cavities, months before those cavities become visible. Research has also shown that the development of oral microbiota is directly correlated to age, meaning the older one gets, the more diverse their oral microbiome should be. Those who develop cavities, however, invariably have a less mature (and hence less diverse) microbiome.

But that’s just the tip of the iceberg. Oral bacteria have now been implicated in a wide range of systemic diseases, including diabetes, rheumatoid arthritis, cardiovascular disease, colorectal cancer, and pancreatic cancer.

Take pancreatic cancer, for example. Research shows that those with significant counts of P. gingivalis and A. actinomycetemcomitans in the mouth have a higher risk of pancreatic cancer. A predominance of Fusobacteria and its genus Leptotrichia, on the other hand, is associated with a decreased risk of pancreatic cancer. It’s not coincidence.

And while the linkages between our oral microbiota and systemic disease may vary, there’s likely one thing they all have in common: our old nemesis—inflammation. Pathogenic species like P. gingivalis promote inflammation in the mouth, thereby contributing to oral disease, but they also exacerbate inflammation in the rest of the body. 

Other typical pathogenic bad boys, like Streptococcus mutans and Candida albicans, produce much the same inflammatory effect. And considering that oral strains have been found in other far off parts of the body, it’s not overly surprising.

The Decline of the Modern Oral Microbiome

A study published in the Journal of Nature Genetics took an interesting look at our oral microbiome history over the millennia. Using calcified dental plaque on ancient teeth, they were able to produce a living oral record through the ages. The research showed that the two major shifts in oral microbiological biodiversity occurred first when we shifted from hunter-gathering to farming, and again when we started mass-producing flour and sugar during and after the Industrial Revolution.

It was at this point that our oral microbiomes became dominated by cariogenic bacteria, and it’s been a slippery slope ever since. As the research team concluded, “modern oral microbiotic ecosystems are markedly less diverse than historic populations, which might be contributing to chronic oral (and other) disease in postindustrial lifestyles.” 

On a lighter note, dental archaeology has revealed some seriously interesting details not only about our own ancestors, but about our close cousins the Neanderthals. DNA extracted from the teeth of five Neanderthals in northern Spain suggests that they may have been pursuing the odd “intimate liaison” with our own human ancestors. How’d they figure that one out? By identifying the presence of a microbe that causes gum disease in modern humans. Not only does this tell us that these folks enjoyed inter-species partnering from time to time, but more to the point, it indicates that many of the microbes in our current oral microbiome were already present at least 50,000 years ago, albeit in a more diverse fashion.

Which brings us around to something else of interest. Inter-species kisses aside, scientists have now shown that an average of 80 million bacteria are swapped between kissers, with those of the French kissing inclination are probably swapping a whole lot more than that. I’ll leave that for your consideration. 

It Comes Down to Balance

A traditional Western take on things is to create two mental bins: one for positive, and one for negative. Then, based on popular consensus, our minds thriftily compartmentalize the phenomena in our lives into one of the two bins. That thing is either good or bad – there’s no middle ground.

Primal thinking dictates a shift away from this black and white view of the world. We recognize that there’s rarely hard and fast “good and bad,” but more a sliding scale that becomes less desirable the further we move away from balance. When homeostasis is achieved, our health flourishes, while the opposite can be said for the outer fringes of that scale.

This, as it happens, is a great way to view the oral microbiome. Far from CW’s anti-microbial standpoint, I’ve already mentioned the diverse and critical roles that the microorganisms in our mouths play in our overall health. When the scale shifts, however, we see an overabundance of pathogenic bacteria, influential in both dental and systemic disease.

It’s that tilt of the scale that we want to avoid. And to avoid it, we need to understand just what’s going on in the microbial communities on our teeth, tongue, gums and cheeks.

Take plaque, for example. One study found that rather than just being composed of blobs of malicious organisms, plaque is actually a highly organized collection of both symbiotic and pathogenic bacteria and fungi that changes over time.

Layer upon layer of microorganisms attach themselves to the tooth, with each layer creating just the right conditions for the next species to move in and set up shop. It’s a very structured system of early colonizers, bacterial yeomen, and microbial aristocrats that are insulated by the vagaries of the mouth through their protective layers of insubordinates.

As with any ecological community, all the species have their place and (in the right amounts) ensure homeostasis is maintained within the mouth. It’s when the pathogenic species, like P. gingivalis, S. mutans and C. albicans, gain the upper hand that things start to go downhill. The key, then, is to encourage all species to live in relative harmony, like one big happy family.

Supporting a Healthy Oral Biome

On the one hand, we have many dentists advocating mechanical abrasion (aka brushing and flossing) as the only way to keep the pathogenic bacteria on your teeth and gums in check. On the other, there are those who recognize the amazingly beneficial role that certain microorganisms play in maintaining a healthy oral (and whole-body) environment. Those people recognize that brushing isn’t selective, and along with mouthwash and fluoride toothpastes, it’s wiping out ALL the bacteria, bad AND good. Kind of like antibiotics do elsewhere in the body.

Studies indicate that beneficial oral bacteria have a far harder time re-establishing themselves in the mouth after disturbance than do pathogenic bacteria. Think of the pathogenic types as weeds—they thrive on disturbance, and can easily out-compete the slower growing beneficial microorganisms under stressful conditions.

With this in mind, it seems prudent to advocate for less of a scorched earth style of oral hygiene and more of a supportive, equilibrium-restoring approach.


If the study I mentioned earlier that examined the change in our dental health over time is anything to go by, turning back the clock and returning to a more Paleolithic (i.e. Primal) style of eating should encourage a more diverse oral microbiome. I also can’t help but think that opting for organic produce would help to re-introduce many symbiotic or commensal microorganisms to our mouths that would otherwise cease to exist on sprayed fruits and veggies. A little dirt in some cases might not be a bad choice either.

Beyond dietary variation, look to alkalizing, nutrient-rich, anti-inflammatory foods to support a healthy microbiome. Anecdotally at least, vitamin C intake appears to be positively correlated with a health oral microbiome, along with A, D, K2 and CoQ10.

Like our gut and other microbiomes of the body, the bacteria living within our mouths behave diurnally, which is to say they’re most active during the day and switch into “maintenance mode” during the night. But that diurnal pattern isn’t driven by light (it’s virtually always dark in there), but by our eating patterns. Since we don’t generally eat during the night, the bacteria in our mouths are rearing to go in the morning at breakfast time and begin to wind-down after dinner every evening.

With this in mind, eating regularity is key. Studies show that disruption to the normal circadian order of things via the likes of jet lag, can dramatically alter the composition of not only your gut microbiome, but your oral one as well. The result is dysbiosis, and, in the gut at least, scientists have found an increase in certain bacteria linked to obesity in people who have flown long distances and hence skipped a few time zones.

“Regularity” might simply mean confining all of your daily eating to certain hours of the day (i.e. an 8 a.m.-6 p.m. window—or shorter), or it could mean imposing Victorian-style meal times of breakfast at 8, lunch at 12 and dinner at 6. And for those frequent fliers who spend the odd day or three abroad, perhaps maintaining a regularity of eating that mimics your home time zone, regardless of what time of day it is at your destination, might be worth the hassle.

The same might apply to variable shift workers. With a notable lack of studies in this area, it’s up to you to experiment and see how your mouth responds.

And remember, saliva is your friend, so keep hydrated. More saliva will have a buffering effect on your teeth, and promote a healthier ratio of beneficial bacteria.


There’s not a lot here that will surprise you. Stress results in dysbiosis of the gut, and it does the same in the oral microbiome. While studies are notably lacking on the effect of stress on the human oral microbiome, work done on squirrels gives a good indication. Maintaining an oral bacterial equilibrium, which is critical to oral and systemic health, means keeping chronic stress to a minimum.

Then there’s smoking. Those nasty warning pictures on cigarette packaging really don’t exaggerate, and the detrimental effects of cigarettes have been shown to extend to the bacteria living in our mouths. More smoking means a greater frequency of pathogenic species.

Oral Treatments

We’ve now drifted into contentious waters. Conventional oral “hygiene” suggests cleanliness, but what is a clean tooth? There are plenty within alternative health spheres who believe that a certain amount of plaque is a good thing, provided it doesn’t get out of hand. OraWellness, who I mentioned a few weeks ago, is one of those groups. Yet, while it does make sense, I’ve struggled to find evidence to substantiate these claims. Who’s going to fund a study that advocates a shift away from toothpaste, toothbrushes, and the billions of dollars they haul in every year?

Once again, I find myself taking the middle ground. I brush, but not too hard, and I don’t stress if I miss a round from time to time. I stay away from fluoride, strong antibacterials, and conventional toothpaste in general. I continue to floss daily. And I’ll swish with salt water on a regular basis. It’s a simple strategy, but it works.

The takeaway here is likewise uncomplicated. Your oral health is what you make it. Diversifying your diet, eating Primally and regularly, minimizing stress, and adopting a more holistic oral care regime will go a long way towards sustaining oral and whole health. 

Thanks for reading, folks. Have you discovered anything about the oral microbiome or good oral care that I haven’t covered? Comments to add? Questions? Share them on the board, and have a good end to your week.

  1. This was a very interesting article its very interesting how many things are happening in each of our body there is a whole tribe of bacteria living in my mouth and we destroy all there work every time we brush :3. I don’t think I will follow there advice on keeping plaque on my teeth that stuff looks horrid D:

  2. What about oil-pulling (or -swishing)? It’s all the rage these days and an alleged panacea for all sorts of problems.

    1. +1 My parents swear by it but I am skeptical to say the least.

      1. Oil pulling might serve as a preventive measure if you start with a squeaky clean mouth (professionally cleaned teeth), but I doubt it will do much for plaque buildup. Swishing with a mouthful of plain water after each meal probably works just as well for dislodging the loose particles. IMO, flossing and brushing are still an excellent idea and hands-down the most recommended by dental professionals.

    2. If you want my N=1 experience? Oil pulling was part of what ruined my teeth, but for people who *aren’t* going through a major health crisis what ruined my teeth will probably help yours.
      What it did, legit, was remove my plaque. But because of the other things going on, it was like ripping off a scab over and over without giving it what it needs to heal. And teeth don’t scar, they just erode.
      So, like, be actual careful especially with coconut oil? If you don’t have your carbs under control or you’re not healthy enough to heal them, getting rid of your plaque is a *bad idea*.

  3. I love eating my local, organic veggies with a bit of dirt. I stopped washing my veggies when my husband and I moved into our cabin without running water, in an effort to conserve water. I am a teacher, surrounded by students who are constantly sick,and I manage to avoid all symptoms during cold and flue seasons. I attribute this to my primal lifestyle and consuming a little dirt!

  4. I feel so powerless to change my oral biome for the better. Even if I happened to be able to do some good, the feedback is so late and so small, it’s really disheartening. I try to tell myself that at least I didn’t pass my bad bacteria to my husband who didn’t have any cavities in at least 5 years despite rarely flossing.

    Also, I noticed that you said the antibiotics are wiping good bacteria elsewhere in the body. Does that mean that I have hope that my last round of antibiotics didn’t wipe all my efforts or am I being too hopeful?

    I even try not to go swimming in chlorinated pools because it’s hard not to get water in my mouth. (And also because of my skin biome but that’s another topic)

    1. Cavity-prone teeth tend to be hereditary. If one or both parents had bad teeth, chances are you will too. This isn’t necessarily carved in stone. It just means you might need to work harder at controlling oral bacteria than your husband does. You might try one of the lozenge-type probiotics. They are designed to be sucked rather than swallowed, thereby improving beneficial oral bacteria.

      1. I always thought that it was the bacteria that were ‘inherited’ from a parent, not the cavity-prone genes. But my mother had all of her teeth removed at 19 years old so I guess you could say she had bad teeth!

        I didn’t know about lozenge-type of probiotics. I will look into it. Thanks!

        1. I just looked into the lozenges and I don’t really see the appeal, it would be 10 times cheaper to just take a normal probiotic capsule and put the content in your food so you get it all over your mouth as you eat. Which I already do but then it’s a question of which strain is better than the other for the oral biome.

          1. You could probably open a regular probiotic capsule and sprinkle the contents directly into your mouth, chewing to get it between the teeth, and leaving it to dissolve for a while before eating or drinking anything. I think if you sprinkle it on food most will go right down your throat. I take VSL#3 probiotics when I need to, and they are anything but cheap. The better brands will need refrigeration and also be fairly pricy.

          2. That’s a good point, maybe I should start doing it like that, I just don’t know which probiotic strains are good for the mouth. It’s hard to find any information on this subject.

            I know that good probiotics are expensive, I was only comparing the cost of lozenges and capsules of the same brand with almost the same strains.

          3. There are very specific strains intended to colonize the oral cavity. Probiotics meant to be swallowed don’t necessarily have the same strains and won’t do the same job if left in the mouth for absorption.

        2. Yes, inherited in the sense of being passed along by mouth kissing and sharing silverware. Pre-mastication is an excellent way to “give” cavities to your baby.

          There could be a million reasons why your mother lost all her teeth at 19. Obviously, she had periodontal disease. Was it because she never or rarely brushed and flossed? Or maybe she did both using perfect technique and with perfect regularity but she had a chronic disease and the medication wrecked her teeth. I don’t have that information. But I can say that it almost certainly didn’t doom her children to losing their teeth young as well.

          1. Well her teeth didn’t just fell out. She just had many cavities and it was the norm in those years to just remove all the teeth even the good ones and have the person wear two dentures.

      2. Cavity-prone teeth are not hereditary. Poor oral hygiene and the SAD may run in families though. 🙂

        (I’m a dental professional)

  5. It seems there would be a way to target the detrimental species while preserving the beneficial biome. I’m not up on my science but peroxide is effective against whatever, gram negative or positive? staph is. Many beneficial bacterial strains tolerate high saline environment that will kill streptococcus, etc. I understand the naturally occurring alcohol sugar, xylitol has the ability to starve off the primary culprit of tooth decay. I believe the compound occurs in Birch trees. So perhaps tooth picks made from Birch twigs would be a primal oral care solution?

    1. Yes, birch xylitol is excellent for starving bad bacteria in the oral environment. One should avoid xylitol made from GMO corn of course.

      And anyone with amalgam fillings should avoid swishing with peroxide as it can break down the metals and release Hg.

  6. Regarding oil pulling, my teeth just feel cleaner and smoother when I do it regularly. They also get super white, but activated charcoal helps with that too. I take a kind of middle of the road stance with oral health. I brush probably more than I should but never use fluoride. Probably stopped using it 20 years ago. Activated charcoal about once a week to whiten. I do remember Weston Price describing how beautiful the teeth were of many of the people he studied who didn’t brush at all. Just can’t go there.

    1. I had my gut, oral, skin, etc. bacteria run by UBiome several times. I discovered I had almost no lactobicilis or bifido in my mouth. I added fermented vegs, kefir, kombucha and I oil pull as well. I started this when I was diagnosed with gum disease. I was able to kill the disease with apple cider vinegar but I continue to have a few twinges in the area even though I’m doing all of the above. Also, I take K2/MK7, COQ10, etc. Btw I didn’t find that oil pulling whitened my teeth but they do feel cleaner.

    2. Regarding not brushing… when I am 100% strict on not eating carbs of any sort – meaning I eat only meat, eggs, green veggies, and dairy such as hard cheese, heavy cream and butter – I have no need to brush or floss.

      I know this sounds gross, but I am a dental auxiliary and I know how to scale teeth. After a good week completely off of carbs, I can do one thorough brushing and flossing and then skip a day and even right after eating, I can’t scale a speck of plaque off of my teeth and the floss come out spotlessly clean.

      I never skip more than a day or two though. That would be gross. LOL

  7. Our early ancestors didn’t brush… didn’t floss… didn’t get cavities. This is my go to line because it seems that the more we brush and floss, the more cavities we get. Obviously, brushing and flossing aren’t the answer, but don’t tell this to the multi-billion dollar dental industry (or most allopathic dentists).

    Wife is a biological dentist (of 20 years)… she, nor the rest of our family brush on a regular basis. No cavities! We do consume lots of organ meats (especially liver which is high is real vitamin A)… We get lots of mid-day sun (extra rich in real vitamin D)… We eat lots of fermented foods (especially kim chi for the vitamin K)…

    Sure, it’s just anecdotal for our family, and for wife’s patients… but it’s not anecdotal for Weston A Price and May Mellanby who published data proving that certain nutrients (most notably vitamins A, D, K) will remineralize teeth to arrest and resist decay.

    So glad that you made mention of these vitamins… including C0Q10. I’d be willing to bet though that most people (even on this site) are still not including organs and fermented foods in their diet… we know that we should, but most are not.

    1. I’d love to work for your wife! I’m a dental assistant and it’s my dirty little secret that my kids and I don’t use fluoride! LOL

        1. Either of you have recommendations re how to stop (lifetime) bruxism which is causing gum recession?

  8. I have been primal since Oct 2011. Eliminated 12 health issues and was able to stop all four prescription medication within the first year. In Dec 2015 I started an experiment to stop using toothpaste. I only thought this would last several days. Well it has now been 1.5 years and still not using toothpaste. I brush with water late morning and I floss several times a year – mostly when popcorn husks get stuck between my teeth. I do go in for twice annual cleanings and I don’t get admonished by the dental hygienist or dentist. The hygienist said I might want to either brush twice a day (still with water only) or change to just before bedtime so that there is less material to form plaque when my saliva flow winds down during sleep. When I first went primal I did have recalcification between two teeth that were of concern. As for cavities I usually had 1 or 2 per year. I have not had a cavity since going primal. Keep those mouth bugs happy!

    1. Toothpaste is a scam. Even in my ultra-mainstream training program, we were taught that dentifrices were merely a vehicle for applying fluoride and it was the physical action of brushing that was all that was needed to remove plaque.

      But, yes, please if you are only going to floss once daily, make sure it is right before bed when you have reduced salivary flow. And maybe floss once a week or at least once a month. It’s a fairly non-invasive thing and it doesn’t have to cost a fortune if you get floss at Dollar Tree. Flossing cleans below the gum where your brush can’t reach. There really are only positives to regular flossing. But yeah I’m with you on the toothpaste thing!

  9. I brush my teeth lightly with an SLS free all natural toothpaste and I do floss. I use a mouthwash that has glycerin, aloe and xylitol. I’ve only had one cavity in my life, a shallow one I didn’t take anything for when the dentist drilled (Ok … not gonna lie it did burn a mbt LOL). So I’m kinda old school compared to a lot of you here. I do take a lot of probiotics and anti-oxidants and supplements. One company puts out a lozenger that supposedly contains specific probiotics for your oral biome.

  10. Mark had recommended Earthpaste and I decided to try it. Silly me though for not reading the label until 3-4 weeks of using it when I saw that it ‘may contain lead’. Stopped my 3 year old from using it immediately and got rid of it. I’m back to a conventional paste (Tom’s gets the best score on ewg) – because I can’t quite do water only.

    1. Don’t brush regularly, nor do I need to but I’ll tell you hands down, the-best-toothpaste-ever award goes to Uncle Harry’s (

      Here are the ingredients: Bentonite clay, calcium carbonate, Purified, deionized, microfiltered water and ten parts per million of silver mineral (99.000% pure), sea salt, ionic minerals, mustard seed, essential oils of spearmint, peppermint, eucalyptus, clove, wintergreen, and oregano. Gluten free, glycerin free, fluoride free, and vegan.

      I’d be doing all a disservice if I didn’t reiterate that it’s the vitamins A, D and K2, in conjunction with magnesium, that are the main players in remineralizing teeth. Take away here is eat your liver and mind your magnesium!!

      1. Some claim that the minerals in the toothpaste help remineralize teeth, from the outside. Otherwise, why would they be in the toothpaste? Your thoughts?

  11. I’ve been using one of the probiotics for your mouth for a week or so, and I’ve noticed that it is really helping with night time dry mouth. I don’t have morning breath, either. It will be interesting to see long term effects.

    1. Hi Colleen! Would you mind sharing what brand you’re using? I have horrible dry mouth at night that is causing me problems. Would love to try what your using! Thanks!

  12. All the data I’ve read also implicates oral health/biome with heart disease. I think after all I’ve read about heart disease, well, heart disease certainly doesn’t sound good.

    I brush and floss (Colgate) and that seems to be okay.

    I had an appointment with a dentist, and he told me to come back if I had any problems. I waited 25 years for my next appointment. Needed a filling and a crown because a filling I got when I was 12 cracked the tooth (he says the old mercury fillings do that over time).

    The oral biome is very important – I think my dabbling in Primal/Keto has been very important to good oral health . . .

  13. Really good post. I think that many of us also abuse of washing and having showers all the time. It is not good for skin bacteria that protect our skin, but it is hard to avoid shower when you have to go to the office! Great blog. Congratulations!

  14. Because I’ve had some pretty severe dental issues over the past few years (mostly due to an incompetent dentist I used for over 20 years), I have done loads of research on oral health, and it seems to be paying off. My routine includes regular oil-pulling, brushing with a soft toothbrush at least 2x/day, using a natural no-fluoride toothpaste (I like Desert Essence and OregaFresh), swishing with sea salt water, and using a WaterPik. I also recommend Ramiel Nagel’s “Cure Tooth Decay” who believes in the Weston Price protocol (very primal I might add); confirming that – as Mark wrote – our diet has played a huge role in. Dental health is CRITICAL for overall health.

  15. This is a subject that I have just been acquainted with. It is interesting how your oral health is directly related to health of your entire body. Thanks for the article share, loved the read!

  16. I want to know about everyone’s breath smell that’s given up toothpaste and mouthwash. If not using deodorants makes you smell a bit natural or ripe, do you also have complaints about breath smelling off? I’m dating and very likely to kiss a date. I am interested in optimal oral health, but i need to stay approachable and kissable! For the last few years I’ve been using mentadent and flossing, and I’m honestly not sure it’s any better than when I used other toothpaste.

  17. What about mouth ulcers, no one has ever even given me an explanation for how to deal with them and why they occur. Any sensible scientific info?

  18. Thank you for shining a light on this topic. I would add: control acid (in the mouth and in the gut….it will destroy dentin and create sensitivity – a baking soda rinse will help), increase minerals in your diet, particularly trace minerals, and optimize Vitamins A, D and K – cod liver oil is great for A and D….K is available in food and supplements. Akamai Mineral Toothpaste is the best for oral health.
