Zinc has a genuine, EU-authorised role in immune function, skin health, and wound healing, though “boosting” immunity is a less accurate description than supporting normal function — particularly relevant if you’re actually deficient. For the full picture, including UK safety limits and absorption tips, see our complete guide to Zinc. Below you’ll find our picks, chosen for well-absorbed forms and appropriate dosing.

Choosing a Zinc Supplement
Zinc picolinate, citrate, and bisglycinate are generally better absorbed than zinc oxide or sulphate. General maintenance doses are 8-25mg daily, matching the UK upper safe level for regular use — short-term higher doses (up to 40mg) are sometimes used at cold onset but shouldn’t become an ongoing habit without medical guidance, given the genuine risk of copper depletion with long-term excess. Take with food to reduce nausea, and avoid combining with calcium, iron, or high-fibre meals, which can reduce absorption. Our full guide covers dosage by use case, interactions, and quality markers in more detail.
