What to look for in magnesium glycinate supplements

Independently tested

An extra layer of quality control: someone other than the maker checks what's inside.

Third-party lab tested: Testing by an outside laboratory rather than the brand itself, typically checking the product contains what the label says and is free from contaminants.

Quality-controlled

Consistent quality from one bottle to the next, made under controlled, documented conditions.

Made in a GMP facility: Good Manufacturing Practice (GMP) is the quality standard for how supplements and similar products are made: clean facilities, documented processes and checks on every batch.

US-manufactured

Made under US manufacturing and labeling rules.

Manufactured in the USA: Made in a factory in the United States.

No GMO ingredients

No genetically modified ingredients, for a cleaner label.

Non-GMO: Made without genetically modified ingredients.

Gluten-free

Fits a gluten-free diet.

Made without gluten-containing ingredients.

Plant-based

Suitable for vegans and vegetarians.

Vegan: Made without animal-derived ingredients.
