🧪 Formulation Notes

The production of the specialized proteins that make up our hair, skin and nails requires high levels of Biotin and we now provide an exceptional 1000 mcg of this essential B-vitamin, a nutrient often provided in minute levels in typical multivitamis. This formula also provides Sulfur from Methylsulfonylmethane (MSM) because Sulfur is essential to the structure of all these tissues and MSM is an exceptional source of organic sulfur. Collagen and silica are additional ingredients included to promote healthy hair, skin & nails. Nature's Lab has included antioxidant vitamins A, C, E, the mineral zinc, plus a berry and veggie complex for enhanced antioxidant benefits.
