  • Bone health

How It Helps

Magnesium Glycinate (also known as magnesium bisglycinate) is well absorbed without significant laxative effects. This favorable absorption makes magnesium glycinate a popular choice for magnesium supplements. The body uses magnesium in more than 300 different functions. As our body doesn’t create magnesium, we must consume enough of this mineral through diet or supplementation. Although abundant in many foods, it’s estimated that about half of the US population doesn’t get enough magnesium.

Magnesium to Improve Sleep Health:

  • Magnesium improves melatonin regulation for better sleep cycles.
  • Magnesium helps calm an overactive nervous system to promote relaxation.

Magnesium to Increase Energy Production:

  • Magnesium helps convert carbs, and other foods, into energy for the body.
  • A drop in magnesium levels is associated with insulin resistance and fatigue.

Magnesium for Better Bone Health:

  • Magnesium helps to regulate calcium levels in bones.
  • Magnesium Glycinate works with calcium and vitamin D to fortify a strong structure for bones.

Magnesium for Optimal Heart Health:

  • Magnesium helps protect blood vessels by helping them relax and pump at a lower pressure.
  • Lower magnesium levels are associated with an increased rate of mortality, according to the American Heart Association.

As a dietary supplement, adults take one (1) capsule 1-4 times daily or as directed by your health care professional.

Frequently Asked Questions

What is Magnesium Glycinate?

Magnesium Glycinate is the magnesium salt of glycine, also known as magnesium diglycinate or magnesium bisglycinate. It benefits sleep health, heart health, energy production, and bone health. Magnesium Glycinate is one of the easier forms of magnesium supplements for the stomach to digest.

Does Magnesium Glycinate have a laxative effect?

A common complaint about magnesium is the laxative qualities of magnesium. Magnesium Glycinate has minimal, if any, laxative effect.

What are some food sources of magnesium?

Green leafy vegetables, nuts, beans, and whole grains are good sources of magnesium, as are coffee, tea, and chocolate. Although magnesium is found in many common foods, US dietary surveys such as the National Health and Nutrition Examination Survey (NHANES) consistently show magnesium intake lower than recommended amounts.

How much magnesium should I take per day?

The Recommended Dietary Allowance (RDA) for magnesium varies by age and gender. Adult women need 310-360 mg per day, while adult men need 400-420 mg. It is important to speak with your physician before taking supplements to understand your specific needs.

How much elemental magnesium is in each tablet?

Each Cooper Complete Magnesium Glycinate tablet contains 120 mg elemental magnesium.

When should I take Magnesium Glycinate?

We suggest that Magnesium Glycinate be taken with your evening meal. Do not take magnesium supplements within two (2) hours of the osteoporosis medication Fosamax. Many antibiotics should be taken at least 2 hours before or 4-6 hours after a magnesium supplement.

What are the signs of magnesium deficiency?

Symptoms of magnesium deficiency can include nausea, vomiting, loss of appetite, fatigue, and weakness. As magnesium deficiency worsens, numbness, tingling, muscle contractions, cramps, seizures, and abnormal heart rhythms can occur.

Who is at risk of magnesium deficiency?

The National Institutes of Health lists older adults and people with gastrointestinal diseases, type 2 diabetes, and alcoholics as top groups at risk of magnesium deficiency.

Should I take calcium with magnesium?

Calcium and magnesium have a complicated relationship. Magnesium is essential for the absorption and metabolism of calcium inside the body. It’s important to keep these two minerals in balance. Too much calcium and/or too little magnesium can have negative health effects. It is important to speak with your physician before taking supplements to understand your specific needs.

Reviews of 120 mg Magnesium Glycinate Supplement

  1. This supplement has helped me to sleep more soundly than I have slept in my adult life. I thought I would always be a light and restless sleeper. Did not want to use sleep aid medications. I have been amazed at the difference Magnesium Glycinate has made (with no side effects). I have recommended it to several friends. It is a godsend for postmenopausal women.
