| The main causes are two and exactly: |
|
 |
For the capsules: The active ingredients inside of a capsule or tablet are absorbed by the intestinal mucous membrane for only about the 50% of those ingested. Too little, therefore, to carry totally out their activity to the detriment of the efficacy existing only on the paper. Furthermore, the active ingredients, used in the nutritional supplements so far, are too limited to be able to produce strong and real efficacy. |
|
For the gel or cream products: the skin human barrier, appointed for the defence of the human body, is too thick and dense for the active ingredients of creams or gel (topical use products) to be able to reach the deepest cutaneous layers so making themselves active in the appointed place. |
