Magnesium Supplement Benefits

As a key element in over 600 biochemical reactions in the body, adequate levels of magnesium can result in numerous health benefits.

Primarily acting as a supporting mineral, the availability of magnesium is essential for optimal health.

One of the most important roles magnesium plays is that of helping to create energy for our cells.
The mitochondria inside our cells need magnesium to create energy for in the form of ATP to keep us alive and functioning.
Without magnesium, the nutrients we absorb could not be metabolised into usable forms of energy.
Our cells then use ATP to as their fuel source or energy to carry out other functions.

Magnesium Citrate has a great absorption rate and mixes well with water. Biosphere Nutrition have used a natural marine based magnesium citrate as one of the best forms for supplementation.

DiMagnesium Malate is a fantastic form of magnesium for people suffering from fatigue, since malic acid is a vital component of enzymes that play a key role in ATP synthesis and energy production. The ionic bonds of magnesium and malic acid are easily broken, making it highly soluble and easily absorbed.

Magnesium Lyscinate Glycinate Chelate is a form of magnesium glycinate bound to the amino acid lysine which keeps the magnesium molecule stable in its journey to the gut for absorption. Formulated by Albion Minerals®, the gold standard in mineral production, their chelated forms of magnesium are designed to be the most bioavailable possible. Magnesium glycinate is extremely easy on the stomach and is a great form of magnesium for those people looking to rectify a deficiency.

Biosphere Nutrition has combined these three forms of magnesium to offer the best rates of absorption while also accommodating to those who are sensitive to magnesium citrate at high doses. By reducing the dose of citrate and including the magnesium malate and lysinate glycinate chelate the Biosphere Magnesium supplement is great for everyone

Sweetener, Flavour and Colour are all from natural sources. We use the best available natural stevia and monk fruit extract to sweeten the powder. The flavour is a natural lemon and the powder is coloured with a dash of turmeric.
