Magnesium, but better. 

Magnesium is one of your body's most important nutrients: a naturally-occurring mineral found in every cell in your body. It plays a crucial role in over 300 enzymatic reactions in the body, including energy production, protein synthesis, and nerve function.

Magnesium citrate is a highly bioavailable form of magnesium that offers a range of powerful health benefits. 

Magnesium citrate is known to support cardiovascular health, promote healthy bones and muscles, and even alleviate symptoms of anxiety and depression.  Additionally, it has been found to support healthy blood sugar levels and improve sleep quality.

Studies suggest that between 10-30% of us may be magnesium deficient, impacting your stress levels & sleep quality and general overall wellness.

What Gives ActiveBurst the Edge

ActiveBurst Magnesium comes in the form of Magnesium Citrate. A much more bioavailable form of magnesium that is gentler on the stomach and much more greatly absorbed.
