• ✓Well-formulated with bioavailable forms (zinc citrate, copper bisglycinate) and collagen co-factors (L-lysine, L-proline, vitamin C)
• ✓Vegan-friendly with a clean ingredient profile and no artificial sweeteners, salt, or starch

Cons

• ✗No third-party testing or certification (e.g. Informed Sport, NSF) disclosed
• ✗Zinc content (15mg at 150% NRV) may cause mild nausea if taken on an empty stomach
