Oxford Origins Micro Zinc vs Vitabiotics Ultra Zinc

Pros

• ✓Ultra-small 6mm tablets are genuinely easy to swallow — the most consistently praised feature across reviews
• ✓Zinc citrate is a bioavailable, stomach-gentle form with good absorption compared to zinc oxide
• ✓120-tablet resealable pouch provides a 4-month supply at competitive value vs. high-street alternatives
• ✓Multiple reviewers report reduced hair shedding, consistent with zinc's role in follicle health

Cons

• ✗Very high dose at 300% RDA (~30mg elemental zinc) — chronic high-dose zinc supplementation can deplete copper over time, a risk not flagged in product information
• ✗No third-party testing or independent certification listed, limiting confidence in label accuracy
• ✗Several reviews are recent 'early days' impressions with no confirmed long-term outcome data
• ✗High dose may cause nausea if taken on an empty stomach — product does not appear to address this
