My daughter started me on your collagen drink as I was having chemotherapy and had lost my hair. Chemotherapy also affects your skin , and nails with many patients losing their nails completely. Although I did lose my hair, it has grown back extremely thick and healthy, my nails remained strong and healthy and my skin is looking quite youthful and plump.(I am 66 so not entirely wrinkle free) Also the medication I have been prescribed since finishing my treatment causes aching joints and so far I have not experienced this . I am putting this down to the effects of the collagen , creating a protective layer for my skeletal system. I enjoy the chocolate fudge protein collagen powder and the vanilla collagen creamer , one scoop of each, In low fat milk which I put into the milk frothed every night after dinner.
