I realize this question might be a bit hard to answer....but what would you say the minimium daily percent of a vitamin should be.

I take a multivitam, but Im wondering if I should throw is some more specific vitamins I think I might need, cause the multi only gives me a certain percent.

For example...my multi gives me 1000% of B-12, but only 200% of D.
Im wondering if 200% should be enough...or if I should take a Vit - D along with my multi.

Some vitamins are water-soluble and some are fat-soluble. Fat-soluble vitamins will accumulate in your system, meaning they can be stored away if not used immediately. Water-soluble vitamins, such as Vitamin C and the various B-vitamins, get flushed out of your system if not used within a short time after ingestion (this is why some vitamins will turn your urine greenish).

The US RDA (recommended daily allowance) that you find on nutritional supplements lists only the amount you need to survive, not what is optimal for your personal health. That is why better multivitamins will have more than 100% of various vitamins (and usually a lot more of the water-soluble ones). Also, some vitamins compete for absorption necessitating that a certain amount be thrown in extra to compensate. However, many vitamins and minerals become toxic in excess (such as Vitamin A and Iron), and therefore you don't want to start randomly throwing in large amounts of specific vitamins on top of a good multi unless you know you're deficient or it's something water-soluble (in other words, taking extra Vitamin C wouldn't be a bad thing, but taking extra of other vitamins might lead to negative effects from too much in your system).

Just get a really good multivitamin (I highly recommend Source Naturals' Life Force Multiple as it is food-based and meets GMP standards) and don't worry about throwing in extra individual vitamins and minerals on top of that unless you have bloodwork done that shows you are in dire need of something.:tu:
