It is vital to distinguish between synthetic vitamins and naturally occurring vitamins. Synthetic vitamins are extracted from non-food sources; for example, many types of B vitamins are extracted from petroleum chemicals; they will not only damage your kidneys, but also deprive your body of other nutrients and minerals before being extracted out of the body (as urine).
“…Many types of B Vitamins are extracted from petroleum chemicals…”
It is important to also understand that natural vitamins do not consist of just one component; they actually consist of multiple components (enzymes, co-enzymes) that work together to give the positive benefits we know of today.
For example, most vitamin C supplements contain ascorbic acid or a compound called ascorbate; this is NOT vitamin C. It only represents the outer ring that acts as a protective shell for the whole mixture of components –Real vitamin C consists of Rutin, Bioflavonoids, Tyrosinase, Ascorbic acid, Factors K, J and P.
If you take a “Vitamin C” supplement with only Ascorbic acid in it – your body has to work to find the rest of the ingredients before it can enjoy the antioxidant benefits real vitamin C has – this is draining for the body, on top of that, the kidneys have to remove Ascorbic acid, as it is not used by the body – this is taxing on the kidneys.
No wonder when researchers (hired by pharmaceutical companies) want to discredit vitamins; they almost ALWAYS carry out studies using synthetic vitamins – not REAL vitamins! This also explains why superfoods, herbs etc give the greatest nutritional healing; as they are not individual extracts of single plant molecules.
