The mineral your defences run on.

Liquid drops held under the tongue are simple to dose and gentle to take — no tablet to swallow, no capsule shell, no binders. You can also fine-tune the amount by the dropper, which a pressed tablet can't do. It's a format that disappears into your routine rather than adding to it.

Zinc sulfate — one of the most established, well-studied forms of supplemental zinc. It's gentle, water-soluble and well suited to a liquid format, delivering 7.5mg of elemental zinc (68% of the daily reference value) per two-dropper serving.

It covers 68% of the daily reference value in a single serving — a sensible daily maintenance level that tops up what the diet often misses, without overdoing it. Zinc is best taken steadily rather than in large occasional doses. If you take medication or have a medical condition, check with your doctor first.

Zinc has a naturally metallic note, so we round it off with a touch of organic apple juice concentrate and an organic glycerin base — the only sweetening in the bottle. No sucralose, no synthetic flavours. Taking it in a little water is an easy option too.

Yes — 100% vegan, gluten-free, non-GMO and alcohol-free, with zero fillers and zero additives. The full formula is zinc sulfate, organic glycerin from flax, purified water and organic apple juice concentrate. Nothing else.

Each 100ml bottle holds 50 servings — around seven weeks at one two-dropper serving a day. Store in a cool, dry place away from direct sunlight. If you're pregnant, breastfeeding, on medication or have a medical condition, check with your doctor first.
