Pros

• ✓Highly tolerated — multiple reviewers explicitly note no nausea or stomach upset, even when taken on an empty stomach
• ✓Copper bisglycinate included at a balanced ratio, preventing zinc-induced copper depletion for safe long-term use

• ✓Clean, verifiable formula — no magnesium stearate, titanium dioxide, artificial colours, or fillers; UK GMP-manufactured

• ✗Effects take time to assess; short-term users (under 2–4 weeks) cannot judge efficacy reliably
• ✗Third-party testing not independently confirmed despite 'lab verified' marketing claim
• ✗Tablet form may not suit those preferring capsules or liquids
