Overview

Youtheory's Collagen + Biotin tablet combines hydrolyzed collagen peptides with biotin, vitamin C and vitamin B, sold in a 390-tablet bottle. It's positioned for hair, nail and skin support rather than a joint or bone-specific collagen product.

No serving size or per-nutrient dose data is listed for this product, so specifics like how many tablets make up a daily serving aren't available from the data provided. The large 390-tablet count suggests a multi-tablet daily serving is likely, which buyers should confirm on the physical label.

  • Hydrolyzed collagen peptides
  • Includes biotin, vitamin C and vitamin B
  • 390 tablets per bottle
  • Marketed for hair, nail and skin support

Who it's for

Buyers looking for a collagen supplement stacked with biotin and vitamin C for hair and nail support. Not the right choice for anyone wanting a single-ingredient collagen product without added vitamins.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Large 390-tablet bottle
  • Combines collagen with biotin, vitamin C and vitamin B
  • Hydrolyzed peptide form
What to check first
  • No per-serving dose data provided
  • Multi-ingredient formula, not plain collagen

Performance notes

Hydrolyzed collagen peptides are broken down for easier absorption, and pairing them with biotin and vitamin C follows the common formulation logic that vitamin C supports the body's own collagen production. Exact per-tablet dosing is not provided in the available data.
