Our bodies convert the food we eat into energy. Nutrients are made so our cells in our organs can get those nutrients. Our organs have 80 percent of their nutrients in our 20s and then they drop to 70% when we hit our 30s. Our Biotin, which is a hair loss treatment, also delivers collagen for stronger, healthier skin. It's a two-in-one solution that combines the advantages of Biotin and Collagen Builder. A lack of biotin can cause hair loss, aging, tiredness and other issues in the human body. You get multiple benefits in one product.
