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

Too large - these capsules !

Posted by 5567994262234224734 on Jun 21, 2017 | Verified Purchase

Im sure the contents are worthwhile, but these capsules are so big! Difficult for adult, let alone a child (mine is magn. def.) so when these are finished - I will find a smaller capsule to give her.

Thanks for your feedback!

Bad acidic or allergic reaction

Posted by Reviewer2238038 on Jun 08, 2017 | Verified Purchase

First of all, do not take it out of the capsule, I tried to swallow the powder out of the capsule with a glass of water, burnt my esophagus. But at least I know now what it is like....probably similar to drinking sulfuric acid from batteries. Your stomach and intestines are lacking pain receptors to detect the harmful effects of this staff....but the damage could be there, and you might not know about it until it's too late. To those who say just follow the instructions and everything will be all-right...I did, and within 2-3 days developed stubbing pain in large intestine which also got swollen (thin feces). Promptly stopped, pain disappeared in a couple of days, took a week for the swelling to go away

Thanks for your feedback!

very sour

Posted by Reviewer2692996 on Jun 04, 2017 | Verified Purchase

I open the capsules and this Mg citrate is very, very sour, and I wonder what it does to the digestion if one swallows the capsule and the content releases inside...Drink it with half litre water!

Thanks for your feedback!
