Added to this is the fact that many vitamin companies use either processed, partially natural or laboratory produced ingredients. They do this because they are far less expensive and probably, in many cases, they are ignorant to the difference.
For example, a vitamin C supplement will usually contain ascorbic acid. On the front of the label it reads, “Vitamin C”, but on the back it reads, “ascorbic acid”. In nature, vitamin C is a whole complex of substances, ascorbic acid being just one. When your body needs vitamin C, it needs the entire complex, not just one part of it—ascorbic acid.
When we take high doses of partial vitamins/minerals, the body is not able to fully utilize these because some of most of the components are missing. The best the body can do with the partial supplements is utilize a small amount, and eliminate the rest. This is why the urine often will be very yellow after consuming laboratory produced supplements found on the market.
Another positive with food supplement that we prescribe is that they are processed at low temperatures which does two things:
It assures that the ingredients are still alive and vital; many food supplements have been processed in such a way that most of the living quality or enzymes have been destroyed. The enzymes are the main ingredient needed to restore health.
With the enzymes still intact, the supplements assimilate much more efficiently. Remember that food supplements must go through the same digestion and assimilation process as food; if you have trouble digesting food, the same will hold true of the average food supplement.
