Magnesium (Glycinate)
Pure Encapsulations is the preferred brand for healthcare practitioners due to its hypoallergenic formulations. Their magnesium glycinate is highly stable and tested for environmental contaminants, making it ideal for individuals with extreme sensitivities.
Ingredients & Purity
120mg of elemental magnesium as glycinate per capsule. Uses ascorbyl palmitate as a stabilizer instead of stearates.
Scientific Evidence
Glycinate (bisglycinate) is one of the most studied forms for sleep and anxiety support due to the calming effect of the glycine carrier.
Brand Transparency
They follow a strict 'open-book' policy for practitioners, though COAs are not as readily available to the public as Nootropics Depot.
Value Assessment
Moderate value. The lower elemental weight per capsule (120mg) means you need 2-3 capsules for a standard dose, increasing the cost per day.
Why Not Alternatives?
Unlike many competitors, Pure Encapsulations does not use magnesium stearate, artificial sweeteners, or coatings. While more expensive than NOW Foods, the purity testing for heavy metals and gluten is more rigorous.
