Vitamin D Council
My mom and I have been having a little argument about Vitamin D--I've been saying it's healthy and you need about half an hour a day at the very least, but she's very skeptical. Today she sent me an email with the following points and the CW websites from whence they came.
"1. Health Risks from Excessive Vitamin D
Vitamin D toxicity can cause non-specific symptoms such as anorexia, weight loss, polyuria, and heart arrhythmias. More seriously, it can also raise blood levels of calcium which leads to vascular and tissue calcification, with subsequent damage to the heart, blood vessels, and kidneys . The use of supplements of both calcium (1,000 mg/day) and vitamin D (400 IU) by postmenopausal women was associated with a 17% increase in the risk of kidney stones
2. Avoid doses of vitamin D above 1000 IU, as this can be toxic.
My question is, do you guys know of any websites or studies that can prove this garbage wrong?
Thanks and Grok On!

Fantastic! That's literally EXACTLY the info I was looking for--and it was in the very first sentence! Thanks a lot. Now I can go and win an argument with my mom :P
Toxic or not, if your body only requires X amount of something per day to thrive and be healthy, whats the point of cramming 10 times that amount in?
Convincing the naive masses that we are all somehow 'deficient' in this or that is a great way to sell supplements.
I think an argument based on supply during human evolution is much more convincing than an argument based on demand determined by a preliminary understanding of its function in the human body.
I have to say I'm skeptical about Vitamin D supplementation (not sun). Mostly because the entire medical establishment is pushing it as a cure-all for everything, which immediately gets my flags up. I'm just not sure enough research is in to be definitive either way. And I'm also skeptical of supplementation in general because, as my doc hubby says, "Americans have the most expensive pee in the world."

It's not a Diet. It's a lifestyle.
I was prescribed doses of 50,000 iu vitamin D by a reputable rheumatologist.
