Frequently Asked Questions
What benefits does magnesium provide the body?
With its involvement in supporting over 300 enzyme reactions, magnesium plays roles in many aspects of health. It is required for normal energy release, regulation of the body temperature, nerve function, adaptation to stress and metabolism. Magnesium works together with calcium and vitamin D to help keep bones strong and support bone mineral density. Magnesium also supports muscle development and movement and the transmission of nerve impulses to the muscles. Studies clearly demonstrate the effects of supplemental magnesium on muscular health. Adequate magnesium levels are also important for cardiovascular health. Studies show magnesium supports a regular heartbeat, thus promoting a healthy heart. Additionally, magnesium helps maintain normal blood pressure.
Why do I need a magnesium supplement?
The recommended daily intake for adults, established by the Australian government ranges from 310-420mg per day. Daily lifestyle factors and poor dietary choices adversely affect the amount of magnesium we are ingesting. Foods rich in magnesium include whole grains, nuts and green vegetables, which are potent sources of magnesium because of their chlorophyll content. Meats, starches, dairy products and refined and processed foods – which make up a large portion of the typical diet today – contain low amounts of magnesium. High-fat diets not only provide lesser amounts of magnesium, but studies have shown that such a diet might even cause less magnesium to be absorbed by the body.
Why were these forms of magnesium (citrate and glycinate) chosen?
Both of these forms of magnesium were carefully chosen based on the latest scientific rationale, as they have been shown to have excellent oral absorption rates and work well within the Isotonix® delivery system.
What other health & nutrition products would complement Isotonix Magnesium?
The benefits of Isotonix Magnesium are complemented by Isotonix OPC-3®, Isotonix Calcium Plus, and Heart Health Omega III Fish Oil*. *Available on SHOP.COM Global.

Hi I would like to know where does our magnesium sourced from? Is it from plant?
Thank you.
Response from Customer Service on 20/11/2022
Dear Valued Customer,
Isotonix Magnesium is a great tasting formula providing the body with 400mg of magnesium in a highly bioavailable formula. Thanks to its unique formula, which includes two different types of magnesium Citrate & Glycinate. Citrate is a magnesium preparation in salt form and Glycinate is formed from elemental magnesium and the amino acid glycine. Both of these forms of magnesium were carefully chosen based on the latest scientific rationale, as they have been shown to have excellent oral absorption rates and work well within the Isotonix® delivery system.
Thank you
