Zinc

An essential mineral with a proper set of authorised claims — used across the range at declared, honest amounts

All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.

Zinc is a tiny mineral with outsized presence on supplement labels. It is one of the few ingredients that carries authorised EU-derived wording — but only in exact phrases and only when the product supplies enough.

This article explains what zinc does in the body in plain terms, which authorised claims can and cannot be used, and how WellsparQ includes zinc across its range. It also flags a likely labelling error in one product and outlines simple safety notes for responsible use.

Zinc is one of the genuinely essential trace minerals: the body cannot make it, keeps only a small reserve, and needs a steady dietary supply. It is also one of the few ingredients in the WellsparQ range that carries authorised health claims — which means, uniquely for this batch, we can say plainly what it contributes, provided we use the approved wording and the product holds enough zinc to earn it. This piece explains the biology, the claims, and how the mineral is used across the range.

Why the body needs it

Zinc is a structural and catalytic workhorse. It is required by hundreds of enzymes and by the "zinc-finger" proteins that help switch genes on and off, which is why it touches so many systems at once — from metabolism to immunity to the making of new cells ^¹. Because there is no dedicated store, zinc status depends on regular intake, and both deficiency and excess have recognisable effects, so the aim is sufficiency rather than loading ^¹².

Human studies using controlled zinc-restriction models have shown how quickly aspects of immune function respond to falling zinc, underlining that this is a nutrient of ongoing need, not a one-off ^¹. Zinc also participates in the body's antioxidant defences — not by acting as an antioxidant itself, but by supporting the systems that protect cells from oxidative stress ^².

The UK Nutrient Reference Value (NRV) for zinc is 10 mg. Good dietary sources include meat, shellfish, dairy, and — relevant for a plant-led range — beans, nuts, seeds and wholegrains, though plant sources also contain phytate, which reduces absorption ^³.

The authorised claims — what we may say

Zinc appears on the list of nutrients with authorised health claims, and WellsparQ may use these only in the exact wording, only attributed to zinc (or to the named nutrient pair), and only where the product provides at least 15% of the NRV — that is, at least 1.5 mg per the amount that carries the claim.

Wording per WellsparQ claims register; these are authorised function claims under retained EU Regulation 432/2012, resting on EFSA's assessments of zinc ^⁴⁵. Two practical rules follow. First, the paired claims (skin with biotin; immune with vitamin B6; oxidative-stress with vitamin E) may only be used where the partner nutrient is also present at its own qualifying level — they are shared claims, not zinc-only ones. Second, the 15% NRV gate is a hard threshold: below 1.5 mg in the claim-bearing amount, no claim may be made at all.

How WellsparQ uses it

Zinc is the most widely used mineral in the range, appearing in seventeen products at amounts from a modest top-up to a full daily reference intake and beyond. The forms vary — citrate and glycinate are both used — chosen for the formula rather than headlined.

Source: WellsparQ Supplements Database. Sixteen of the seventeen products sit at or above the 15% gate and can carry the authorised wording (subject, for the paired claims, to the partner nutrient). The seventeenth — VitaBright Gummies at "1.5 µg" — is a thousand-fold below a plausible zinc dose and almost certainly a µg/mg unit error on the source data; as written it is far below the claim threshold and no zinc claim may be made for it. Flagged for data correction below.

Where zinc is the only mineral in a formula, the cards say so with characteristic plainness — "the formula's single mineral," "the one nutrient with a reference value on this label". The mineral forms used are plant-compatible, and the products are suitable for vegetarian and vegan diets.

Sensible use

Zinc is safe and essential at the amounts used here. It is worth knowing that very high intakes over time can interfere with copper absorption; the UK tolerable upper level from supplements is 25 mg/day, and the products above sit within sensible daily use. Taking zinc with food reduces the chance of mild nausea. Anyone pregnant, breastfeeding, on medication or combining several zinc-containing products should check the total and, if unsure, speak to a GP or pharmacist. Take as directed.
