I stopped getting the little white spots in my nails almost immediately after starting PB. I used to also get horizontal ridges on all my nails, regularly spaced about 1/4" apart....any guesses what that was from? I haven't had any of those for many months; the only exception was one ridge which seemed to correlate pretty closely in time to when I got a letter from the unemployment people, saying my benefits were cut off. It's grown out now, and I'm loving my nails again
I had horizontal ridges from when I transitioned to PB. All gone now and my nails are much stronger (although a little more brittle).
Try looking for nail cream to strengthen them. years ago, I've similar problem but now gone after using nail cream. I can't remember the brand though. Check out your local pharmacy. they may be able to help.
FWIW and AFAIK, the 'white spots = zinc deficiency' thing is a myth. I've always had these, so I've hunted around in the past for some authoritative information on the cause, without finding anything. 'Trauma' and 'inherited tendency' are about as far as it goes. There might be slightly fewer spots since going Primal, or there might not.

It's said to be biotin (B7) deficiency. Grains can, apparently, interfere with biotin metabolism. Professor Cordain points out Lindow Man's last meal consisted of grains and adds:
Less well-appreciated are the ability of whole grains to impair biotin metabolism. My colleague, Bruce Watkins [Watkins 1990], as well as others [Blair 1989; Kopinksi 1989], have shown that biotin deficiencies can be induced in animal models by feeding them high levels of wheat, sorghum, and other cereal grains. Biotin-dependent carboxylases are important metabolic pathways of fatty-acid synthesis, and deficiencies severely inhibit the chain-elongation and desaturation of 18:2n6 (linoleate) to 20:4n6 (arachidonic acid). Human dietary supplementation trials with biotin have shown this vitamin to reduce fingernail brittleness and ridging that are associated with deficiencies of this vitamin [Hochman 1993].
I guess it's a fairly big jump from Lindow Man's last meal that to the assumption that he regularly ate high amounts of grains (and, presumably, little meat or dairy products). He wasn't particularly short and he was well-built and probably of high rank, after all. The last meal may have had a ritual significance, bearing in mind how he likely met his end. (He was possibly "killed" three times - the Celts had a thing about triads.) There are indications that the sacrificial victim may have chosen the wrong lot, having picked a piece of burnt cake (what Lindow Man may have consumed).
The bannock was then broken into small pieces and put in a bag. The person who chose the burnt piece of bannock became the sacrificial victim. [Anne] Ross believes that Lindow Man was a Beltain sacrifice.
However, whatever was going on with Lindow man "Human dietary supplementation trials with biotin have shown this vitamin to reduce fingernail brittleness and ridging that are associated with deficiencies of this vitamin" sounds fairly conclusive for a connection between biotin deficiency and fingernail ridges.
Oh no, could this be indicative of addison's disease? My grandmother had it.
Adrenal fatigue (to which there are varying degrees of- Addison's being an extreme) is so common these days. Our modern lifestyle is so bad for our poor adrenals! We have chronic low grade stress, stay up too late/don't get adequate sleep, drink caffeine/stimulants, etc. all of which can wear on our adrenals over time.
I recommend doing a bit of reading about adrenal fatigue- there are tons of articles out there. Primal is an excellent diet to help the adrenals.
