Key Facts

  • Magnesium bisglycinate is a chelated form of magnesium bound to the amino acid glycine, designed for superior absorption and minimal digestive upset
  • Supports muscle relaxation, bone density, cardiovascular function, and healthy stress response through its role in over 300 enzymatic reactions
  • Particularly useful for sleep quality and anxiety management, since magnesium helps regulate neurotransmitters involved in relaxation

Ingredients

Magnesium (as magnesium bisglycinate) 200 mg, citric acid, monk fruit.

Why We Chose This

Most people don't get enough magnesium from food alone, yet this mineral is fundamental to how your muscles contract, your heart beats, and your nervous system calms down. The bisglycinate form is the standout here because glycine acts as a carrier, allowing your body to absorb magnesium more efficiently while bypassing the laxative effect common with other forms. This formulation supports restful sleep and cardiovascular health without the digestive side effects that make people abandon supplementation. At 200 mg per serving, it's a research-backed dose that fits into a foundational wellness routine.
