Longevity Science Magna-Calm is a water-soluble form of magnesium citrate with a pleasant effervescence, and a good-tasting natural lemon flavor. One scoop provides 420mg of elemental magnesium, which is rapidly absorbed, even in cases of poor digestion.
- Excellent source of highly absorbable magnesium
- Pleasant, unsweetened natural lemon flavor
- All ingredients are derived from natural sources
Magna-Calms benefits are two-fold: 1) The water-soluble nature of the preparation makes the mineral more absorbable from the intestinal tract, and 2) the chelating agent used is citric acid to yield magnesium citrate, a form shown in clinical research to be significantly more absorbable in humans than other forms of magnesium.
Reports have shown that at least 70% of Americans are magnesium-deficient. The results of a Gallup survey showed 72% of Americans are falling short of the recommended amounts of magnesium.
Commenting on the report, Richard Rivlin, MD of the Memorial Sloan-Kettering Cancer Center, said there was "a high general awareness of the importance of nutrients such as vitamin C and calcium, but it is clear that consumers are largely unaware of the role of magnesium." Another survey presented to the Autism Society of America cited a magnesium deficiency figure of 80% among Americans.
Many factors can increase the rate of magnesium depletion in the body. Physiological factors, such as mental or physical stress, an underactive thyroid, diabetes, and chronic pain can all contribute to depletion of magnesium.
Dietary habits, such as higher consumption of sugar, coffee, soft drinks, use of several types of medical drugs, and diets high in carbohydrates, fiber, or calcium may also, in part, lead to magnesium deficiency.
Magnesium absorption is as important as magnesium intake. Most people believe that regular magnesium supplements, such as tablets or capsules, will resolve magnesium deficiency. Unfortunately, however, individuals can supplement with the RDI for magnesium every single day and still be in a deficient state.
Studies show that many common forms of magnesium are poorly absorbed. Magnesium citrate is one of the most absorbable forms. Magnesium is more bio-available in water than in the diet, with one preliminary human trial showing 30% greater absorption. Water-soluble magnesium is clearly the preferred dosage form.
