For skin elasticity and connective tissue support, this product delivers 6g of **Collagen Peptides** per 6-tablet serving — right in the clinical sweet spot. Most skin-focused RCTs show benefits starting at 2.5–10g daily, so you're solidly in range. The grassfed bovine source provides Type I and III collagen, the types most relevant to your skin and hair.

**Vitamin C** at 60mg supports collagen synthesis in your body, though the dose is modest. **Biotin** at 5,000mcg is at the top of the supplement range, though clinical evidence for hair and nail benefits is strongest in individuals who are actually biotin-deficient.

The main tradeoff is pill burden. Six tablets per serving is a lot to swallow daily, and the 270-tablet bottle only lasts 45 days. If you find that manageable, the collagen dose itself is well positioned for results. A powder format would deliver the same collagen with less hassle.
