Magnesium is an essential mineral that contributes to normal psychological function, normal functioning of the nervous system, a reduction of tiredness and fatigue and normal muscle function. L-threonate is a metabolite of vitamin C; bound to magnesium it forms a highly soluble organic salt. The capsules contain only Magtein®, the vegetable-cellulose shell and rice flour, with no preservatives or chemical additives.

ProHealth was founded in 1988 in Santa Barbara, California, and now trades as ProHealth Longevity, a specialist in cellular-health and healthy-ageing nutrition. Every product is manufactured in the USA in FDA-registered, GMP-certified facilities, and each batch is third-party tested in US laboratories with Certificates of Analysis published for customers to read. This open, test-and-publish approach to purity and potency aligns closely with Welzo's commitment to clear, quality-led nutrition, and Welzo's healthcare professionals assessed the brand for alignment with our standards before it was added to the marketplace. Brain-Mag Pro stands out in Welzo's magnesium range because it is built on Magtein®, the patented and clinically studied form of magnesium L-threonate, rather than a generic threonate salt. ProHealth doses it generously at 2000 mg per serving, yielding 144 mg of elemental magnesium, where many competing products supply 1300 mg or less. The formula contains nothing but Magtein®, a vegetable-cellulose capsule and rice flour; it is kosher certified, free from GMO and BSE/TSE risk, non-irradiated, non-ETO treated and suitable for vegetarians and vegans. Each batch is third-party tested in US laboratories with the Certificate of Analysis published, so the magnesium content of the exact lot can be checked. That combination of branded raw material, higher dose and verified purity reinforces our trust in their quality philosophy.
