About this product
Nutritional support for skin, hair and nails is the clearest use, especially when zinc or copper intake falls short. The serving provides 15 mg zinc as citrate and 2 mg copper as glycinate, both clearly identified mineral sources. Vitamin C at 120 mg also supports normal collagen formation.
The ingredients aimed at visible cosmetic changes have more important limits. OptiMSM supplies 1000 mg, below the 3000 mg exposure associated with the controlled cosmetic findings, while the silicon dioxide and red-algae mixture is not established as the preparation linked to hair and nail outcomes. Its source proportions are unclear, so the silicon declaration alone cannot predict those results.
The 50 mg amounts of L-proline and lysine add little support for the main goals. The formula fits someone seeking combined mineral and connective-tissue nutrition, but evidence for visible improvement is less certain once nutrient needs are met. Its value rests more on the combined nutrients than on obtaining a meaningful amount of proline.
Pros
Zinc citrate and copper glycinate are favorable identified mineral sources Vitamin C complements the minerals' normal connective-tissue roles Individual active amounts are disclosed
Cons
Silicon source proportions and equivalence to the relevant studied preparation remain unclear MSM amount is below the controlled cosmetic comparison exposure The small proline amount contributes little value as a proline supplement
