Life Extension: High-Dose Magnesium Supplement

Life Extension’s magnesium capsules are designed to help adults meet their daily magnesium needs more effectively. Just one capsule a day can fulfill magnesium requirements. The magnesium in Life Extension capsules comes in various forms, including magnesium oxide, magnesium citrate, and magnesium succinate. The manufacturer claims this blend promotes better absorption and utilization in the body.

It’s essential to note that each capsule of this supplement contains 500mg of magnesium, which is significantly higher than the daily recommended intake. Because of this high dose, it’s recommended to consult with a doctor before starting.

Magnesium Forms and Research:

Magnesium Citrate

Magnesium citrate is a form of magnesium bound with citric acid, a naturally occurring acid in citrus fruits that gives them their sour taste. It’s a common ingredient in magnesium supplements.

  • According to a small-scale study involving 14 male participants, magnesium citrate is one of the most easily absorbed forms of magnesium by the body. This means its absorption rate in the digestive tract is better than other magnesium supplements. [1] Trusted Website PubMed is a data base from US National Institutes of Health. It’s a trusted source of health and medical information. Open the link →

People often take magnesium citrate orally to boost their magnesium levels. Moreover, due to its natural laxative effects, it is sometimes taken in higher doses to treat constipation.

Magnesium citrate is occasionally promoted as a relaxant, claimed to help with symptoms related to depression and anxiety. However, these claims require more scientific research for validation.

Magnesium Oxide

Magnesium Succinate

Nested Naturals: Easing Mental Anxiety

The active ingredient in Nested Naturals magnesium supplement is magnesium bisglycinate, known to have high bioavailability. Additionally, this product doesn’t contain calcium, helping to ensure better absorption of magnesium. It’s also fully vegan, meaning no animal ingredients are used, and is GMO-free, offering a dependable option for those seeking natural products.

Worth mentioning, many reviews point out that this product doesn’t induce any laxative effects, a significant plus. Diarrhea is a common side effect of many magnesium supplements.

  • No laxative effect.
  • Easily absorbed, high bioavailability.
  • No calcium content, promoting absorption.
  • Vegan, non-GMO.
  • Third-party tested.


  • Price might be higher than similar products.

Magnesium Glycinate and Research

Magnesium Glycinate is a compound formed by combining basic magnesium with the amino acid glycine. This amino acid plays a role in protein synthesis in the body and is also widely present in foods like fish, meat, dairy products, and legumes.

  • Animal studies suggest that glycine itself might help improve sleep quality and potentially have therapeutic effects on some inflammatory conditions such as heart disease and diabetes. However, more research is needed to confirm these findings. [7] Trusted Website PubMed is a data base from US National Institutes of Health. It’s a trusted source of health and medical information. Open the link →
  • Due to its good absorption and calming properties, Magnesium Glycinate is thought to aid in reducing issues like anxiety, depression, stress, and insomnia. Research indicates that taking an appropriate amount of Magnesium Glycinate daily can significantly improve symptoms of depression, anxiety, and memory decline. The exact mechanism behind this effect isn’t fully understood. One hypothesis is that people with low magnesium levels might be more affected by mental health issues. However, blood magnesium tests haven’t consistently shown this correlation. Studies suggest that symptoms might start appearing before a magnesium deficiency is detected through blood tests. [8] Trusted Website NCBI, US National Center for Biotechnology Information, is a trusted source of biotechnology and biomedicine information. Open the link →

More Forms and Research on Magnesium

In addition to the magnesium forms mentioned above like magnesium oxide, magnesium citrate, magnesium malate, and magnesium glycinate, there are more forms of magnesium. Here are 7 additional forms of magnesium along with relevant scientific research for your reference when choosing magnesium supplements.

Magnesium Chloride

Magnesium Lactate

Magnesium lactate is a compound formed by the combination of magnesium and lactic acid. Lactic acid is a naturally occurring acid in muscles and blood cells and is widely used as a preservative and flavor enhancer in foods. Magnesium lactate is primarily used as a food additive to adjust the acidity of foods and beverages and enhance their nutritional value. While it may not be as popular as a dietary supplement, it doesn’t mean it lacks advantages.

Magnesium lactate is easily absorbed by the digestive system and is gentler on the gastrointestinal tract. This characteristic makes magnesium lactate an ideal choice for individuals who need long-term or high-dose magnesium intake or are sensitive to other magnesium supplementation methods. In a study involving 28 patients with a rare disease requiring significant daily magnesium intake, the group using magnesium lactate extended-release tablets reported significantly fewer digestive system side effects compared to the control group.
