Is taking a supplement of collagen and HA effective for skin rejuvenation?

Doctor Answers 1

Not at all...

HA is a sugar and collagen a protein, so they are destroyed in your G-I tract and absorbed as their basic substances (a disaccharid and several aminoacids). Taking supplements for sure increases the amount of substances useful to build up your skin but it doesnt mean rejuvenation. You better take the precursors of HA (glucosamine sulphate) and collagen (some aminoacids and Vitamin C useful in the synthesis of collagen)
