Why glycinate

Not all magnesium is created equal.

Magnesium oxide is cheap and poorly absorbed. We chose glycinate, magnesium bound to the amino acid glycine, so it's gentle on digestion and readily taken up by the body.

  • Chelated form. Bound to glycine for high bioavailability and better tolerance.
  • Single ingredient. Just magnesium glycinate in a vegetable capsule. Nothing else.
  • Zero fillers. No magnesium stearate, no artificial flow agents, no binders.

Good to know

Questions, answered.

Why magnesium glycinate instead of oxide?

Glycinate is magnesium bound to the amino acid glycine. It tends to be gentler on digestion and more readily absorbed than cheaper oxide forms.

When should I take it?

Most people take 1 capsule daily with a meal. Many prefer the evening as part of a wind-down routine.

Is it vegan and free from common allergens?

Yes. It is Vegan, Non-GMO, and free from gluten, soy, dairy and added sugar. The capsule is vegetable-based (hypromellose).

Where is it made?

It is manufactured in the USA in a cGMP-compliant facility, and we keep the label to a single active ingredient.
