If you're looking for hair, skin, and nail support, this gummy leans almost entirely on **Biotin** at 5,000mcg — a high dose, but one that only has clinical evidence for people who are actually biotin-deficient. If your biotin levels are normal, research does not support meaningful benefits for your hair or nails at any dose.
The remaining ingredients are dosed well below clinical ranges. **Zinc** at 2.7mg is about 18% of the minimum supplemental dose studied for skin health. **Vitamin C** at 20mg is 8% of the typical supplemental range. **Vitamin D** at 5mcg uses the D2 form, which is significantly less effective than D3 at raising your blood levels. **Vitamin B12** at 6mcg uses cyanocobalamin, a synthetic form that requires conversion in your body.
This is a multivitamin at maintenance-level doses with a large biotin add-on. If you're looking for meaningful support for hair, skin, or nails, the doses here — outside of biotin — are too low to move the needle.
