I was recently asked to review you theory and I got the Collagen in vanilla powder. If you do not know the importance of collagen well it is the main protein of connective tissue and is responsible for: skin firmness, skin moisturisation, skin suppleness, constant renewal of skin cells. Research proves explicitly that the skin ageing process occurs in connective tissue, whose main ingredient is collagen. As we age we lose collagen which is so sad I am starting to see the results and I am in my late 30’s my skin is starting to look horrible and not such a baby face I had in my 20’s. This powder has 6 grams of collagen per scoop and contains 18 amino acids, gets maximum absorption, added joint formula. It also help aide in stronger nails, hair, ligaments, tendons, beauty inside and out. How you take it is 1 scoop in water or fruit juice then drink. It has Collagen, Vitamin A, Vitamin C, Vitamin E, Copper, Silica and Biotin. Of course before starting you can consult your physician to make sure it is ok to take.
My Opinion: I found the flavor to be pleasant and helped my skin over time I would say 1 week. I definitely would recommend.
