A very affordable, broad-spectrum multivitamin marketed for hair, skin, and nails, but generally contains insufficient dosages of key active ingredients, especially biotin, for significant therapeutic effects.
The 21st Century Hair Skin & Nails supplement is positioned as a comprehensive blend targeting a vast array of health goals, including specific benefits for hair, skin, and nails, alongside general well-being, energy, and cognitive support. It features a broad spectrum of vitamins (A, C, D3, E, and a range of B vitamins including Biotin), essential minerals (Calcium, Iron, Phosphorus, Iodine, Magnesium, Zinc, Manganese, Potassium), and other compounds like Choline, Inositol, PABA, Tyrosine, and Cysteine. While its multi-ingredient approach is appealing for general nutritional gaps, the product's primary weakness lies in the significantly low dosages of several key active ingredients relative to their purported benefits, particularly for Biotin (25mcg) which is foundational for hair and nail health in dedicated supplements. The inclusion of a 'Proprietary Herbal Support Blend' also lacks transparency, preventing an informed assessment of its contribution to the stated goals. Despite a high review count, likely reflecting its affordability, the low potency across many categories limits its efficacy for specific, noticeable improvements, positioning it more as a very basic, entry-level multivitamin with a marketing emphasis on beauty benefits that are under-dosed.
- Very affordable price per serving ($0.12).
- Provides a wide range of basic vitamins and minerals.
- High review count suggests general consumer satisfaction or perceived value.
- Extremely low Biotin dosage (25mcg) for a product specifically targeting hair, skin, and nails, where 1000-5000mcg is more common and effective.
- Many B vitamins and Vitamin D3 are present in low dosages, limiting their impact on energy, cognitive function, and bone health.
- The 'Proprietary Herbal Support Blend' lacks transparency, making it impossible to evaluate its efficacy or specific components.
- Attempts to address too many broad goals, potentially diluting the effectiveness for any single specific benefit.
- Individuals seeking significant improvements in hair, skin, or nails from biotin may find the dosage in this product to be largely ineffective.
- Those with specific vitamin or mineral deficiencies will likely require higher, more targeted supplementation than what this product provides.
- The 'Proprietary Herbal Support Blend' means consumers cannot verify the amounts or types of herbs included, which may be a concern for those with allergies or specific dietary restrictions.

The product acts as a basic multivitamin providing a wide array of essential nutrients, though many are at modest dosages, offering foundational support rather than comprehensive optimization for overall health.
Immunity 35.0
Vitamins A, C, E, and Zinc offer general immune system support, but the dosages are moderate and not optimized for robust immune boosting compared to specialized immune health products.
Energy 30.0
The B vitamins, crucial for energy metabolism, are present but at relatively low concentrations (e.g., 5mg Thiamine, 25mcg B12) compared to high-potency B-complex supplements designed for energy enhancement.
