An Important Note on Dosage Before You Buy
This product provides 50mg of zinc bisglycinate per 2-tablet serving, which is the manufacturer’s suggested daily intake. It’s important to be direct about this: the UK’s safe upper level for regular, ongoing zinc intake from supplements is 25mg daily — the manufacturer’s suggested 2-tablet serving is double this amount, and taking 50mg daily for the 6+ months this bottle is designed to last goes beyond what’s generally considered safe for sustained use without medical supervision. Sustained excess zinc intake is genuinely linked to reduced copper absorption and, over time, potential copper deficiency and other effects.
Because each tablet provides 25mg — exactly matching the UK’s safe upper level for regular use — taking one tablet daily, rather than the two suggested on the product, is a more appropriate approach for ongoing, long-term supplementation. Two tablets daily (50mg) may be appropriate short-term in specific situations, such as at the onset of a cold, but this should be limited to a matter of days, not sustained for months, and is worth discussing with a GP or pharmacist rather than defaulting to the manufacturer’s standard serving suggestion. Our complete guide to zinc covers dosing by use case, absorption tips, and interactions in full detail.
Zinc bisglycinate is a chelated form, where zinc is bound to the amino acid glycine — a form generally considered gentle on digestion and well absorbed. Zinc has a wide range of EFSA-recognised roles, including normal immune function, skin, hair, nail, and bone maintenance, cognitive function, protein and DNA synthesis, cell protection from oxidative stress, and normal fertility, reproduction, and testosterone levels in the blood — genuine, established roles, though these reflect zinc’s normal physiological function rather than a reason to exceed safe intake levels in pursuit of more benefit.
This product is manufactured in the UK, vegan and gluten-free, and free from GMOs, lactose, and magnesium stearate. Speak to your GP before starting zinc supplementation if you’re pregnant or breastfeeding, take regular medication, or have an existing health condition — and specifically before taking more than one tablet daily on an ongoing basis, given the dosage consideration above. Store in a cool, dry place away from direct sunlight, and keep out of reach of children.
