The Purpose

Highly absorbable magnesium for active days.

Magnesium 3-in-1 combines three well-studied forms, glycinate, malate and citrate, delivering 384mg of elemental magnesium (102% NRV) per serving. It’s a gentle, vegan-friendly formula that helps reduce tiredness and fatigue and supports normal muscle function and electrolyte balance.

Active adults lose magnesium through sweat and the demands of daily training, so a steady daily intake matters. Train hard most days? Pair it with The Performer creatine and electrolytes.

The Ritual

Take your Magnesium 3-in-1 consistently, every day, as part of your routine. Many customers take theirs in the evening with a meal.

Serving size: 2 capsules with water, ideally with food.

Prefer not to swallow capsules? Open them, pour into a smoothie and blend. Drink immediately.

Training hard? Magnesium also contributes to normal protein synthesis, so it pairs well with our Halal Bone Broth Protein Powder.

The Science

Magnesium contributes to a reduction of tiredness and fatigue, normal muscle function, normal psychological function, energy-yielding metabolism, normal functioning of the nervous system, electrolyte balance, normal protein synthesis, and the maintenance of normal bones and teeth.

Each form brings something different. Glycinate is a highly bioavailable form of magnesium, known for being gentle on the stomach. Malate combines magnesium with malic acid. Citrate is magnesium bound to citric acid, another well-absorbed form.

Two capsules provide 384mg of elemental magnesium, 102% of the daily Nutrient Reference Value.
