The full guide

What Nutricost Potassium Magnesium Citrate Provides

Nutricost Potassium (99 mg) Magnesium (210 mg) Citrates is a gluten-free, non-GMO mineral supplement packaged in a 240-capsule bottle. Each serving delivers 210 mg of magnesium as Magnesium Citrate and 99 mg of potassium as Potassium Citrate. The citrate forms are chosen for perceived digestive tolerance and mineral absorption. The product carries gluten-free and non-GMO labeling, and claims of third-party testing and facility compliance (GMP/FDA-related claims) are listed in some sources. At roughly $13.95 for 240 capsules, it offers a long-lasting supply. Consumers often appreciate the convenience of citrate-based minerals, which some users report as gentler on digestion and easier to take compared with separate potassium and magnesium pills. While many reviews highlight positive effects on cramps and general well-being, a few note capsule fragility or inconsistent magnesium effects.

Who Might Benefit

This supplement is often considered by people looking to support electrolyte balance, particularly those experiencing leg cramps or seeking better sleep and recovery. The 240-capsule bottle provides a long supply, which can be convenient for ongoing use. The citrate forms and gluten-free, non-GMO labeling make it appealing to individuals who prefer these attributes and want to avoid gluten-containing ingredients.

Use, Taste, and Durability Considerations

Because the product comes in capsules, it has no taste impact typical of powders. Some user reviews mention that capsules can be flimsy or break easily, which may affect convenience or perceived product integrity. The magnesium content is described as being in the citrate form, with some variability in magnesium efficacy reported by users. The price per capsule is approximately $0.06, offering value for those who want a long-term, citrate-based mineral supplement.

Gluten Safety and Certifications

The product is labeled gluten-free and non-GMO, which is supported by product data and some retail listings. However, explicit gluten-free certifications (such as GFCO or NSF) are not cited in the supplied evidence. Cross-contact details are not provided, and while the facility is described as GMP/FDA-associated in some sources, cross-contact protocols are not stated.
