Frequently Asked Questions

They’re all magnesium. The word after “magnesium” tells you what it’s bound to, and that changes how it feels and how much you get.

This one is magnesium citrate: 400 mg of magnesium per 2 tablets. It’s well absorbed, and often chosen for regularity.

Other magnesium we carry:

Glycinate (100–200 mg per serving; capsule, gummy): gentle and highly absorbable, a popular evening choice.

Citrate (325 mg per serving; powder): well absorbed, and often chosen for regularity.

Oxide (400–482.6 mg per serving; tablet): the most magnesium in each tablet.

Gluconate (27 mg per serving; tablet): a gentle, lower-dose form that’s easy on the stomach.

Multi-form complex (250 mg per serving; capsule): several forms of magnesium in one capsule.

Compare labels by the magnesium amount, not the compound weight. Taking medication, or have kidney concerns? Ask your healthcare provider which form suits you.

Most people notice a difference within 2–4 weeks of daily use.

Supplements work gradually, so consistency matters most. Take it at the same time each day and check in on how you feel week to week.

Take 2 tablets daily as a dietary supplement or as directed by a healthcare professional.

It’s made under the FDA’s current Good Manufacturing Practice (cGMP) rules, which require every batch to be tested for identity, strength and purity.

Certifications: Non-GMO, Gluten-Free, Vegan, Made in the USA, No Artificial Colors, No Artificial Flavors, No Preservatives, Sugar-Free, Dairy-Free, Soy-Free.

We buy directly from authorized Windmill distributors — never marketplace resellers.

Generally, yes.

Space calcium, iron, zinc and magnesium about two hours apart, and check your other supplements for the same ingredients so doses don’t stack up.

Taking medication, pregnant or nursing? Ask your healthcare provider first.

Return any unopened bottle within 30 days of delivery for a full refund. No restocking fee.

Arrived damaged or wrong? Send us a photo at moorevitamins.com/contact and we’ll refund or replace it.
