Amer Don Magnesium Glycinate 400mg vs Pure Encapsulations: Which Formula Fits You?

Choose Amer Don for a 400mg magnesium glycinate serving with added vitamin B6 and vitamin D, or choose Pure Encapsulations for magnesium glycinate with dairy-free and non-GMO labels at the lower listed price.

Last updated Aug 1, 2026

Choosing between sleep stress supplements can come down to more than the word "glycinate." One formula pairs magnesium with vitamins B6 and D and states a 400mg magnesium serving, while the other keeps its active-ingredient line focused on magnesium glycinate and carries dairy-free and non-GMO labels. With just a $0.41 spread between their listed prices, the formula details are the more meaningful deciding factor.

Quick verdict

Pick Magnesium Glycinate 400mg - Chelated High Absorption, For Sleep, Stress Relief when you specifically want 400mg of magnesium from magnesium glycinate per stated two-capsule serving and want vitamin B6 plus vitamin D in the same capsule formula. Pick Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief when dairy-free and non-GMO attributes are priorities, or when the lower listed price matters. Both are capsule-format magnesium glycinate options and list gluten-free among their features.

Where each formula wins

Amer Don wins on a more layered ingredient profile. Its stated serving delivers 400mg of magnesium from magnesium glycinate and adds vitamin B6 and vitamin D. That clear combination is the strongest reason to select it over a magnesium-glycinate-focused active-ingredient line.

Pure Encapsulations wins for its dietary-preference labels and slightly lower listed price. It is marked dairy-free, gluten-free, and non-GMO, with a listed price of USD 13.58 versus USD 13.99 for the Amer Don formula. The $0.41 difference is small, so this choice is more about those listed attributes than price alone.

Product notes

Magnesium Glycinate 400mg - Chelated High Absorption, For Sleep, Stress Relief

The defining reason to choose the Amer Don formula is specificity: it states 400mg of magnesium from magnesium glycinate per two-capsule serving, with vitamin B6 and vitamin D also listed as active ingredients. That makes it a direct match for shoppers looking for a magnesium glycinate supplement that includes those additional vitamins rather than magnesium alone. Its listed attributes also include alcohol-free, gelatin-free, and gluten-free, and the formula uses a vegetable capsule. The tradeoff is the broader formula itself. Shoppers who prefer an active-ingredient line centered only on magnesium glycinate may find Pure Encapsulations more aligned with that preference. Its USD 13.99 listed price is also the higher of the two.

Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief

Pure Encapsulations is the better fit when dairy-free and non-GMO labels are important alongside a magnesium glycinate capsule. Magnesium glycinate is the listed active ingredient, while glycine appears in the ingredients, making the formulation straightforward for shoppers focused on that magnesium form. It is also labeled gluten-free and has a neutral flavor listing. At USD 13.58, it carries the lower listed price in this comparison. The limitation is not about the capsule format-both choices are capsules-but about formula preferences: Pure Encapsulations does not provide the same vitamin B6-and-vitamin-D combination highlighted by Amer Don. For shoppers specifically seeking the 400mg magnesium amount stated in the Amer Don description, that competing formula is the more direct match.

Final choice by use case

Choose Amer Don Magnesium Glycinate 400mg for a stated 400mg magnesium serving paired with vitamins B6 and D, especially if gelatin-free and alcohol-free attributes appeal to you. Choose Pure Encapsulations Magnesium (Glycinate) for magnesium glycinate with dairy-free and non-GMO labels, plus the lower USD 13.58 listed price. If neither set of formula attributes is a priority, the narrow $0.41 price spread means either capsule can be a reasonable category match.
