If your goal is healthier skin, nails, and hair, this formula takes a nutrient-support approach rather than providing the high-dose specialist ingredients (like collagen or hyaluronic acid) that clinical research most strongly supports for those goals. What this means for you: the strongest contributor is **Zinc** at 15mg in bisglycinate form — a well-absorbed form right at the minimum clinical dose, relevant for skin and immune health.
**Vitamin C** at 200mg sits within the supplemental range and supports collagen synthesis in your body. **Nettle** at 500mg is within its studied range for general nutritive support. **Vitamin B6** uses the active P5P form at 4mg, and **Vitamin E** at 20mg as natural d-alpha-tocopherol is a premium form at a meaningful dose. **Biotin** at 300mcg is well below the 1,000–5,000mcg range typically used in hair and nail supplements.
The main limitation for your skin and hair goals is the absence of collagen, hyaluronic acid, or astaxanthin — the ingredients with the most direct clinical evidence for visible skin and hair results. This product delivers solid micronutrient support, but it's not a specialist formula.

Rice FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
Rice ProteinFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports have documented elevated arsenic in rice products). Used as a cheap filler. Incomplete amino acid profile adds no meaningful protein benefit at excipient doses.
