In order to benefit from the miraculous effect of collagen, it must be digested and absorbed in the body as well as possible. For this, collagen should have as small a molecular structure as possible.
Many clinical studies have been carried out in order to make good use of collagen, and it has been concluded that the collagen recommended for use in foods should be smaller than 2500 Dalton molecular weight. It is recommended that the particle size of the collegen be smaller for greater benefits in terms of higher absorption and bioavailability.
Again, researches show that in order to benefit from the positive effects of hydrolyzed collagen peptide, it should be used regularly in the recommended amount every day.
Protecting your youth is now easier with Vitaminica's natural vitamin C source, Acerola extract, and collagen supplements containing Collagen +C produced from hydrolyzed bovine collagen peptides.
