This dosage of Biotin is considered to be at a clinically studied level, which research suggests may support hair, skin, and nail health. The product also includes 46 mg of Calcium, which is underdosed compared to typical daily recommendations. With an N+ Score of 57 and an 'F' grade, this product is in the average tier, primarily due to its limited ingredient profile and the underdosed secondary ingredient.
