+ 30 mg zinc per serving supports immune health + Includes copper to help balance zinc’s antagonistic effect + Rarely seen excipients (modified cellulose gum and silica) set it apart from many zinc tablets + Transparent dosing across the range
- Zinc and copper compete for absorption; high zinc may reduce copper uptake (risk 6/10)
Larger pack sizes tend to sit in a lower‑price tier, while smaller packs are positioned as budget options. The formulation is consistent across flavours and sizes, offering the same zinc‑copper ratio and tablet base; the only notable variant differences are the flavour‑specific ingredients and the price‑tier variation. The presence of modified cellulose gum and silica, uncommon in comparable products, is a distinguishing feature, while the inherent zinc‑copper antagonism warrants mindful timing or supplemental copper.
