The headline ingredient here is **MSM** (OptiMSM), dosed at 1,000mg — right at the minimum of the 1,000–3,000mg clinical range. OptiMSM is the most studied branded form, purified by distillation, so you're getting a legitimate dose of bioavailable sulfur to support keratin production and connective tissue health.

**Zinc** at 15mg (citrate form) sits at the bottom of the studied range, and the inclusion of 2mg **Copper** in a well-absorbed glycinate form is a smart functional pairing — zinc depletes copper over time, and this product accounts for that. **Vitamin C** at 120mg supports collagen synthesis, though it falls well short of the 250mg+ range used in clinical research.

The weak spots are the amino acids. **L-Proline** and **L-Lysine** are each dosed at just 50mg — roughly 10% and 5% of their respective studied ranges. At these amounts, they're contributing very little toward collagen building. **Silicon** is listed at 50mg, but it's in the silicon dioxide form, which has minimal oral bioavailability. If you're buying this for skin and hair support, the MSM is doing the heavy lifting — the supporting cast is largely underdosed.
