READER COMMENT: I believe it is not the calcium itself, but rather the inhibitory effect the calcium divalent ion has on the uptake of magnesium by cells…..they compete.  So when taking calcium supplements it is important to take magnesium too, in supplement form.  Magnesium is clearly important for cardiovascular health. 
ROC REPLY: Thanks. Interesting comment.  I have been struck by evidence that overconsumption of calcium leads to buildup many places, like the throat.  Also, at the Linus Pauling meetings a few years back, it was reported that taking much higher levels of vitamin K led to activation of many decalcification enzymes.  Doing this was supposed to lead to a 50% decrease in the rate of heart attacks.  I have long maintained that what is important is getting enough vitamin D, which maintains bones, and weight bearing exercise, rather than Calcium, which most people get enough of in an average diet.

READER QUESTION: Last week I started taking Biotin 5000 mcg in hopes of helping my skin & hair be healthier.  Age sometimes isn't too kind to hair & skin.  Is biotin 5000 mcg  good for this?  I just started last week.
From what I read, it is unnecessary, and the literature I read suggests many other supplements listed here.  “The general daily recommended dosage of biotin is 2.5 mg (or 2,500 mcg), according to Dr. Scher. However, it’s not clear what the correct dosage is for the full effect, but it’s important to consult your doctor to avoid overdosing. Dr. Stuart suggests looking out for these possible signs of biotin overdose: slower release of insulin, skin rashes, lower vitamin C and B6 levels and high blood sugar levels.“ Biotin is widely distributed in foods. Foods relatively rich in biotin include egg yolk, liver, whole cereals, and some vegetables (nuts and legumes).
