Vitamin D Deficiency: Common And Problematic Yet Preventable

Understood. As for the D, most of what I've read lately has placed a safe upper tolerable limit for adults at 2000IU a day, as long as you get a good calcium & magnesium intake to go with it. In which case I'm okay.

As for A, yes I know about that. The best way for you to get A is from Beta Carotene.

C is about the only thing I would consider being mega dosed, and it is water soluble, and not stored in the body. BTW: Did you know that humans are one of only three or four mammals in the world that do not produce their own C?

Thanks, although I knew about that fact regarding vitamin C production in humans.

As for the upper tolerable limits for vitamin intake, do remember that the experiments are done with laboratory-grade vitamins, which are of higher purity than what’s normally available at the pharmacist.

I’m not exactly worried about the quantity of vitamins, but rather, the quantity of impurities within it. Contaminants like chemical catalysts used during the synthesis, microscopic fragments of the equipment used to perform the reactions during manufacture, etc.

Anyway, you’d know better as to what you’re consuming...

Of course it does. I’ve learned about this in my nursing classes so I suppose my advice would pertain to the northeastern USA. :) Either way - the SUN is important for our health.
