ZeinPharma L-glutathione capsules provide you with reduced highly-dosed L-glutathione in enteric-coated capsules. In addition, the L-glutathione is protected by ascorbic acid. The bioavailability is thus greatly increased in contrast to conventional products.
By adding ascorbic acid in the L-Glutathione capsules, the reduced, bioactive form is retained for you!
Reduced L-glutathione gets oxidised very fast because it is very re-active. On the one hand, this is desired, on the other hand it should take place only in the body cells, not already on the way there.
Therefore, ascorbic acid is added to L-glutathione. Ascorbic acid is probably more familiar to you as Vitamin C. It acts as an antioxidant and protects L-glutathione on its way into the body cells. Premature oxidation would limit its effectiveness. To prevent this from happening, it is protected from too early reaction by ascorbic acid.
