Taking a supplement like Pure Encapsulations Magnesium Glycinate aid the body in activating enzymes that are required for a variety of physiological activities, including neuromuscular contractions, heart function, and maintaining the body's acid-alkaline balance 1.

Magnesium is required for carbohydrate, amino acid, and lipid metabolism, as well as energy production and the utilization of calcium, phosphorus, sodium, and potassium. This essential mineral also aids in the utilization of B-complex vitamins, vitamin C, and vitamin E 2.

Maintaining adequate levels of magnesium — and avoiding the health concerns caused by a lack of it — doesn't have to be a problem with the help of an efficient dietary supplement such as Magnesium (Glycinate) Capsules from the brand Pure Encapsulations.

Pure Encapsulations Magnesium Glycinate Capsules provide an effective and potent form of magnesium.

Benefits Of Pure Encapsulations Magnesium Glycinate

Magnesium is required for metabolism, energy production, and efficient utilization of calcium, phosphorus, sodium, potassium, and vitamins C, E, and B-complex in the body 3.

Supplementing with magnesium is shown to be a good way to improve the body's ability to metabolize a range of nutrients and components, including lipids, amino acids, and carbs, resulting in increased muscular growth and a reduction in the appearance of fat on the body.

In fact, in a cross-sectional study of 210 old people, supplementing magnesium was linked to improved lipid metabolism and lean body mass 4.

Bone Health

Magnesium is an essential component in the bone matrix that encourages healthy bone metabolism. It contributes to bone strength by maintaining appropriate bone density 5.

A clinical study involving 2,038 older people found that higher magnesium intakes were positively related with bone mineralization in certain (experimental) groups.

Cardiovascular Health

Magnesium supports a wide range of cardiovascular functions, including arterial efficiency, endothelial function, c-reactive protein (indicator of inflammation) metabolism, and lipid metabolism. It has also been shown to reduce irregular health rhythms 6.

According to a meta-analysis of 20 randomized trials, magnesium glycinate improved systolic and diastolic function, as well as proper glucose metabolism as it aids in the regulation of blood sugar in diabetics and reduces the risk of acquiring diabetes 6,7.

Higher magnesium intakes were connected to a healthy functioning cardiovascular system and improved glucose utilization in a 15-year research study involving 4,637 young individuals. Magnesium is also essential for muscular function, mood and relaxing, and cranial vessel comfort 8.

Mental Health

According to some research, magnesium glycinate may also aid with mood swings because the mineral is involved in the modulation of neurotransmitter receptor sites in your brain. In fact, a magnesium deficiency may contribute to anxiety, confusion, poor memory or focus, irritability, and difficulty sleeping 9.
