Product Overview


  • Bioavailable Mineral for Cardiovascular Health
  • Dietary Supplement

Magnesium is one of the body’s most important minerals. It is required as a cofactor in hundreds of enzymatic processes within cells. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, promotes healthy cardiovascular function, supports a healthy immune system, and keeps bones strong. Magnesium also helps maintain blood sugar and blood pressure levels already within normal range, and it is known to be involved in energy metabolism and protein synthesis.

Magnesium is a major factor in relaxing the smooth muscles within the blood vessels, thereby reducing peripheral vascular resistance and promoting a healthy cardiovascular system. Magnesium also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide.

Magnesium positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding. Scientific literature documents the need for a wide range of minerals, including calcium and magnesium, that are vital to maintaining strong, healthy bones.

Moreover, there is strong evidence that dietary magnesium intake and supplementation improves the metabolic profile. Magnesium has been shown to beneficially impact insulin resistance, serum lipid profiles, inflammation, endothelial dysfunction, oxidative stress and platelet aggregability. Since magnesium is so inexpensive, everyone should consider supplementing with at least 500 mg of magnesium daily. This product provides one of the highest concentrations of elemental magnesium per capsule available on the market.

A review of assimilation studies suggests that the citrate salt of magnesium is the best absorbed into the bloodstream. Magnesium Citrate, however, is comprised of only 16% magnesium, and the typical dose of elemental magnesium is 100 to 350 mg a day. Higher doses of 300 mg to 548 mg daily have been shown to help support healthy blood pressure

No potence

Posted by demonic-tree on Jan 14, 2017

The last batch i bought has a strong acidic taste on the capsule's surface. Moreover it stopped work for me, so i needed to increase the dosage twice. My guess the citric acid wasnt fully reacted with magnesium (too little magnesium). Later it took some air humidity and leaked a bit through the capsule. Regardless of this to be right or not the last batch has no potence and there're cheaper alternatives for magnesium citrate on iherb. Probably wont buy again

Good price-quality ratio, transdermal still more important

Posted by Suppster on Jan 12, 2017

I recommend taking Magnesium via skin mostly but especially in the beginning it is good to take orally too. This is handy on the go too sometimes. Magnesium is so important for all of us. In this day and age, everyone needs to supplement it.

Tras tomar este suplemento un tiempo, el sueño se ha hecho más reparador (no más prolongado) y mejora el tránsito intestinal. Solo toma una al día antes de acostarse.
