Everything people ask us.
If your question isn’t here, get in touch — a person answers, usually within one working day.
What exactly is in the capsules?
Magnesium: magnesium glycinate in an HPMC (vegan) capsule. Zinc: zinc glycinate in an HPMC capsule. No bulking agents, flow aids, anti-caking agents or colours.
Where are they made?
Encapsulated and packed in the UK. The raw minerals come from audited suppliers, and each shipment arrives with a Certificate of Analysis, which we publish.
Is the Certificate of Analysis independent?
No — it is the ingredient supplier’s certificate for the batch of mineral we buy, confirming identity, potency and purity. Independent testing of the finished capsules is planned for the next production run, and will be published either way.
How many should I take?
Magnesium: two capsules a day with food, ideally in the evening. Zinc: one a day with food. Do not exceed the stated dose.
Can I take them together?
Yes. Many people take magnesium in the evening and zinc with a daytime meal.
How long until I notice anything?
Most people notice a difference within one to two weeks. Tiredness and fatigue tend to respond first.
Will magnesium upset my stomach?
Glycinate is the form least likely to. That is the main reason we chose it over citrate or oxide.
Are they vegan and halal?
Yes. The HPMC capsule is plant cellulose and there are no animal-derived ingredients.
Can I take them with medication?
Magnesium can interact with some antibiotics and blood-pressure medication, and zinc with some antibiotics. Check with your pharmacist or GP first.
Delivery and returns?
Free UK delivery, usually 2–3 working days by Royal Mail. If it is not for you, email us within 30 days for a refund — opened bottles included.
When is Zinc back?
Early October. Leave your email on the Zinc page and you will hear first.
