The Active Ingredient Is: Magnesium (Citrate Form)

Magnesium citrate is a mineral that’s essential for normal muscle and nerve function, and energy production in the body. This form is highly bioavailable and sourced as magnesium citrate, helping daily wellness and the physiological processes that support muscular and nervous system health.

What Does Magnesium (Citrate Form) Do?

Magnesium helps with muscle function and energy production, and is involved in maintaining normal nervous system activity, with evidence that supports its role in blood pressure regulation in adults.
