What to Look for in Your Magnesium Supplement

Most doctors are aware of the different formulations of magnesium supplements, but the majority of consumers are not fully armed with the information. The magnesium supplement you choose will determine how much your body can absorb and how effectively it will help you with your health condition. Knowing about magnesium absorption will empower you to better manage your illness or condition that requires or can be helped with magnesium. You might have heard of magnesium oxide, citrate, the chelates and an array of others. But what exactly do all these terms mean and which one is the best for you? Most of the oral magnesium products available have never undergone rigorous absorption efficacy trials so it can be very confusing to you and the magnesium deficient community looking for a reliably absorbent magnesium supplement.

 On a basic level, the different magnesium formulations have significantly varying rates of absorption. One formulation not mentioned enough in the mainstream media and online communities is magnesium L-lactate dihydrate, which is the magnesium in the trial tested formulation of Mag-Tab® SR (sustained release). The Magnesium L-lactate dihydrate in the Mag-Tab® SR formulation offers the highest clinically proven oral absorbency rate available as a supplement. This is wonderful news in treating magnesium deficiency associated with the symptoms of many illnesses as well as the American epidemic of magnesium deficiency.

Mag-Tab® SR’s L-lactate dihydrate sustained release formulation is better absorbed by the body because when taken twice daily, it allows for a prolonged slow release of the magnesium L-lactate into your gastro system over a 24 hour period. Thus, when absorbed, it allows the kidney to more effectively distribute the magnesium you need back to your body’s cells. Many people who have taken Mag-Tab® SR for years had it originally prescribed by doctors who were familiar with this process and Mag-Tab® SR’s exceptional absorption rate and low GI side effects. In fact in over twenty years, two hundred plus million doses of Mag-Tab® SR have been recommended by physicians to people needing our product’s attributes.

Over the years, the Mag-Tab SR trials were conducted to provide the data to tell our absorption story. Mag-Tab® SR’s absorption rate has been documented at 41.1%. No other formulation has documentation to compare. The absorption section of our web site contains an array of documents detailing absorption, side effects, dosage, and comparative description of about every type magnesium salt available. This is what we used to generate the comparison chart on our website and featured above.

Suffice to say there are many different magnesium salts available and the range of absorption described is from a low of 2% with the oxide ( the most common available in all stores ) and then up to 20-30% for the chloride, citrate, and chelated magnesium products. And then there is Mag-Tab® SR with over 40%. We hope you’ll want to experience the Mag-Tab® SR difference as there definitely is one.

Dr. Steven Belknap, a clinical magnesium expert, summarizes our story from a doctor’s perspective:

Many physicians are familiar with the problem of poor bioavailability of most magnesium salts, including the ‘oxide,’ the most widely-available available oral formulation of magnesium. Patients with migraine, diabetes mellitus, hypertension, or ethanol abuse are often at risk for hypomagnesemia. The problem is that magnesium oxide is relatively insoluble in aqueous solutions, and is not effective in most patients when given as a supplement. Mag-Tab® SR is a sustained-release formulation of magnesium L-lactate dihydrate that provides controlled release of highly bioavailable magnesium in the gut lumen. Mag-Tab® SR provides an effective way to replete and maintain magnesium levels in the body.
