The Single Most Influential Mineral

300

Magnesium supports more than 300 enzymes in the body that are crucial for a health and energy.

4th

Magnesium is the fourth most abundant mineral in the body.

2

Formulated with two highly bioavailable forms of magnesium for superior absorption and function.

The Mighty Magnesium, Citrate & Glycinate

Adequate magnesium intake plays a vital role in supporting cognitive health, including concentration, memory and overall mental clarity. In contrast, low magnesium levels have been associated with decreased focus, reduced cognitive performance, muscle discomfort and poor sleep quality. Isotonix® Magnesium is expertly formulated with two highly absorbable forms of magnesium — citrate and glycinate — to maximize bioavailability and support optimal absorption. Each serving delivers 100% of the recommended daily value, helping you maintain healthy magnesium levels for cognitive support, muscle relaxation and restful sleep.

It's More than Just an Electrolyte Booster

Magnesium is essential for a healthy lifestyle! Working in harmony with calcium, it helps regulate your heart and maintain normal blood pressure. But that’s not all—magnesium also supports your body’s ability to build strong bones and teeth and promotes proper muscle development. When combined with calcium and vitamin D, magnesium helps keep your bones resilient and healthy, so you can stay active and feel your best every day!

Frequently asked Questions

What benefits does magnesium provide for the body?
With its involvement in supporting over 300 enzyme reactions, magnesium plays roles in many aspects of health. With regards to bone health, it is an important component of the mineralized part of bone and supports the normal metabolism of calcium and potassium in adults. 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. Magnesium supports normal protein synthesis. As such, there is evidence that magnesium helps maintain normal blood sugar levels.
How much magnesium should I be getting, and why do I need a magnesium supplement versus getting it from my normal diet?
The recommended daily intake for adults, established by the Institute of Medicine of the National Academy of Sciences, states that adult males between the ages of 19 and 30 should be receiving 400 mg of magnesium daily. Adult females of the same age should receive 310 mg daily. For older males, the recommendation is 420 mg daily, while older females should consume 320 mg daily. 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 in today’s society — contain low amounts of magnesium.
What is the Isotonix delivery system, and how does it work?
Isotonic, which means “same pressure,” bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state. When an isotonic substance enters the body, it will be absorbed into the bloodstream rapidly. Isotonix dietary supplements are delivered in an isotonic solution, allowing nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.
Does this product need to be taken on an empty stomach?
Yes. For maximum absorption, the product should be taken on an empty stomach.
What other health and nutrition products would complement Isotonix Magnesium?
The benefits of Isotonix Magnesium are complemented by Isotonix OPC-3®, Isotonix Calcium Plus, Isotonix Vitamin D with K2 and Heart Health™ Omega III Fish Oil with Vitamin E.
What is the best way to store this product?
Keep Isotonix products stored in a dry, cool place. If Isotonix products are stored in the kitchen, keep them away from the stove, sink, heat-generating appliances or window ledges. If you live in a very humid area, you may store Isotonix products in the refrigerator — but not in the fruit and vegetables area.
