Ingredient origins and dietary suitability

The magnesium comes from mineral ore. Citrate is made through corn-dextrose fermentation; ascorbyl palmitate originates from corn-dextrose fermentation and palm oil. The formula is described by Pure Encapsulations as vegan, vegetarian, gluten-free and non-GMO. Its product information lists no wheat, soy, dairy, eggs, tree nuts, peanuts or sesame, and no magnesium stearate, artificial colors or sweeteners, coatings, shellacs, unnecessary binders, fillers or preservatives, trans fat or hydrogenated oils.

Frequently asked questions

Who is this formula intended for, and how is it taken?

The manufacturer identifies this capsule formula for adults 18 and older. Its suggested daily amount is one to four capsules, taken with food. Follow your healthcare professional's individualized guidance rather than treating the upper end of that range as a target.

Does 150 mg refer to magnesium or the whole citrate compound?

It is the elemental magnesium amount, not the total weight of magnesium citrate. Pure Encapsulations lists minerals by elemental weight.

How is citrate different from glycinate?

Citrate and glycinate are different magnesium forms. Pure Encapsulations notes that citrate can loosen stools, especially at higher supplemental amounts, while glycinate is less likely to do so. The manufacturer's citrate information describes a mild stool-softening effect from magnesium remaining in the intestine. Ask your healthcare professional which form and amount suit your needs.

Is it appropriate for someone with a corn allergy?

Do not rely on a corn-free claim to establish allergy safety. Pure Encapsulations explains that corn-derived ingredients are purified away from their fermentation starting materials, but it does not routinely test for corn allergens and cannot guarantee safety for someone with a corn allergy. Discuss the exact bottle ingredients with your healthcare professional.

Can it be taken with medication?

Check first with your prescriber or pharmacist. The manufacturer's professional resource flags possible reduced absorption of oral bisphosphonates, such as alendronate, and tetracycline antibiotics when taken with magnesium. Some acid-reducing medicines, thiazide diuretics and metformin can also affect magnesium status. This is not a complete interaction list or advice to change medication.

How should it be stored, and what warnings apply?

Keep the bottle somewhere cool and dry and out of children's reach. Seek professional advice before use if pregnant, breastfeeding, living with a health condition or taking medication. Use only with an intact safety seal.

Why might the bottle look different from an older photograph?

Pure Encapsulations has removed some plastic neckbands and introduced smooth bottles without embossing. These packaging changes do not by themselves indicate a formula change; the protective seal beneath the cap should remain intact.
