New Leaf Zinc vs Vitabiotics Ultra Zinc

Pros

• ✓Small, easy-to-swallow tablets praised by multiple reviewers as a standout feature
• ✓Zinc citrate form has good bioavailability — superior to zinc oxide used in cheaper alternatives
• ✓Copper included to counteract zinc-induced copper depletion — a responsible formulation choice
• ✓Strong value for money; 120 tablets providing a 2-month supply at competitive pricing

Cons

• ✗50mg per serving (500% NRV) significantly exceeds EU and UK upper tolerable intake levels (~25mg/day) for unsupervised daily use
• ✗At least one reviewer reported headaches upon use — consistent with known high-dose zinc side effects
• ✗Minor packaging complaint: safety cap reportedly difficult to open
• ✗Product listing claims 'Vegan' in the title and description, but product data flags this as unconfirmed — prospective vegan buyers should verify directly
