What makes Magtein® Magnesium L-Threonate Supreme different?
Magnesium L-threonate is magnesium bound to threonic acid, a metabolite of vitamin C.
Threonic acid has good gut bioavailability and is able to cross the blood-brain barrier, as it is naturally occurring in the cerebrospinal fluid.
Formulated with Magtein®, a unique patented form of magnesium L-threonate that has been shown to increase levels of magnesium in the brain compared to other forms.
Summary of Studies
Studies show that Magtein® improves cognitive function, especially in older adults undergoing memory tests.
Adults aged 50–70 were given Magtein® or placebo for 12 weeks. The Magtein® group significantly improved their stress and anxiety levels compared to the placebo group, thus improving overall quality of life.
Adults aged 35–55 with self-reported sleep problems maintained good sleep quality and daytime functioning with the introduction of Magtein®. The control group had overall improved sleep quality, mood, energy, alertness, and productivity, while the placebo group saw a decline.
Frequently Asked Questions
What is Health First and what does the brand offer?
Health First is a Canadian premium supplement brand exclusive to Health First Network member stores. Products are made in Canada using non-GMO, gluten-free ingredients and manufactured in government-inspected cGMP-certified facilities. Independent laboratory testing verifies potency, purity, and safety for every product. The range covers vitamins, minerals, essential fatty acids, digestive enzymes, herbals, immune support, joint and inflammation formulas, cognitive health, sleep, and children's products. Notable formulas include Magnesium Bisglycinate 200 Supreme, Cal Mag Supreme, and Berry C Supreme. The brand is available exclusively through Health First Network independent natural health retailers.
What sets Health First apart from other Canadian supplement brands?
Health First's defining characteristic is its exclusive distribution through independent natural health retailers within the Health First Network — it is not sold through mass market chains, pharmacies, or major online marketplaces. This channel exclusivity means the brand is formulated and positioned for the knowledgeable natural health consumer who shops at independent health stores, not the casual supplement buyer. Product formulations consistently prioritize bioavailability — using bisglycinate mineral forms, active B vitamin coenzymes, and food-form nutrients rather than cheaper synthetic alternatives. The government-inspected cGMP manufacturing and independent third-party testing at the batch level represent a documentation standard that many brands state but fewer consistently practice.
