Your skeletal and cardiovascular systems require throughout your lifetime. When you age‚ those systems are at greater risk for disease and inflammation. Regular exercise (at least 30 minutes per day‚ four days per week) and a nutrient-rich diet low in salt‚ sugar‚ and saturated fat can help. However‚ if you're post-menopausal‚ have a family history of heart or bone diseases‚ or just need additional support‚ you may want to take a magnesium supplement.

Although most people focus on taking calcium or vitamin D supplements to support their skeletons‚ magnesium is another important nutrient. Almost half of your body's magnesium content is in the bones‚ while the other half circulates through the bloodstream.

Magnesium helps calcium and vitamin D promote bone strength. It also helps prevent potentially painful inflammation. The average adult gets enough magnesium through diet; however‚ some people take magnesium to help prevent a deficiency or to treat one.

Magnesium Oxide 500 mg by Douglas Laboratories provides enough of the mineral to help prevent and treat magnesium deficiency. In addition to its benefit to your bones‚ it also supports cardiovascular health.

Each bottle of Douglas Labs’ Magnesium Oxide 500 mg contains 250 capsules‚ which should last for approximately 25 days if taken at the recommended daily dosage of one capsule per day.

Since its founding in 1955‚ Douglas Labs has been on the leading edge of nutritional technology‚ allowing it to provide superior vitamins and other supplements.
