About Magnesium Glycinate

What is it about Magnesium?

Magnesium is one of the most deficient minerals in North American diets. The recommended daily allowance for magnesium in adults is 400-420 mg per day. Dietary sources of magnesium are greens, nuts, seeds, dry beans, whole grains, wheat germ, wheat and oat bran. With the rise in diagnosed food allergies and sensitivities, as well as stress-related illness, it can be challenging to meet even the body’s basic daily requirements for magnesium through diet alone.  

Since individual needs vary according to health status and stress levels, supplementation can provide a safe, convenient, and effective way to meet them.

What Does Magnesium Do Exactly?

Magnesium is a mineral that is necessary for over 300 different biochemical reactions in our body. It’s roles include, but are not limited to, the transport of calcium and potassium across cell membranes, heart beat regulation, muscle function and nerve impulse conduction.  It is involved in the synthesis of proteins, energy production, and blood glucose metabolism.  These traits make magnesium status influential in blood pressure, sleep, diabetes, and chronic muscle pain syndromes.

Why I Haven’t Changed My Magnesium Formula in Twenty Years – and why it still works!

There are many types of Magnesium that you can buy – and every variation will have a different dose, a different price, and a different ability to be absorbed most easily by the body.

Our Magnesium contains a unique formulation that combines fully reacted Magnesium Glycinate with  Magnesium Oxide and L-Glycine chelated (bonded) together. It is this chelation that dramatically improves the absorption of our product compared to products that use other forms of Magnesium, like Citrate, Malate, or Oxide (that isn’t chelated).

Reports of unwanted side effects like bloating, gas, and diarrhea with the use of magnesium citrate, sulfate and malate supplements often happen because these forms aren’t as well absorbed from the gut into the blood – and the unabsorbed portion can cause these side effects.

In our formula the dose per capsule has proven time and time again to be the most effective at helping people achieve the goal of replenishing their body without the side effects mentioned above. And while there are many companies that have come out with formulas that show higher doses – they are likely to cause the same side effects because they aren’t as well balanced as our formula.
