Our premium blend of multi collagen not only contains collagen types I, Ii, Iii, X, V it also contains collagen boosting ingredients: Biotin, Vitamin C and Hyaluronic Acid for maximum effectiveness. Studies have shown that after the age of 25 collagen production naturally decreases. As we age supplementing with collagen can help support healthy skin, hair, nails and joints. Vitamin C supports the synthesis of collagen, while biotin and hyaluronic acid both support skin health. Please note that the jar will only be sixty percent full. This is done so that powder does not escape during filling, and is standard for any powder filling.
