What is magnesium threonate

Magnesium L-threonate, often referred to simply as magnesium threonate, is a compound formed by combining magnesium with L-threonate, a salt of threonic acid. Threonic acid is a derivative of the sugar, xylose. This specific compound is notable for its potential ability to penetrate the blood-brain barrier, a protective barrier that separates the bloodstream from the brain, allowing it to potentially impact cognitive function and brain health.

Some key points about magnesium threonate include:


  • Bioavailability: The bioavailability of magnesium threonate is believed to be relatively high, meaning that it can be effectively absorbed by the body. This is partly due to its ability to cross the blood-brain barrier, allowing magnesium to reach the brain more easily than some other forms of magnesium.

  • Cognitive Benefits: Magnesium Threonate's unique property to penetrate the blood-brain barrier has led research to suggest that it may support cognitive function and memory. Some studies in animal models have indicated that magnesium threonate supplementation may increase synaptic density and plasticity in the brain, which are associated with learning and memory.

  • Research: Research on the cognitive benefits of magnesium threonate is ongoing and relatively limited, especially in human studies. Although preliminary findings are promising, more research is needed to fully understand its effects and how they compare to magnesium and other forms of cognitive enhancers.

  • Dosage: The appropriate dosage of magnesium threonate can vary based on individual needs and health goals. If considering supplementation, it is important to follow dosage instructions on the product label or consult with a health care professional.

  • Counseling: If you are interested in using magnesium threonate for cognitive support or other health reasons, it is advisable to consult with a healthcare provider. They can provide personalized guidance based on your health status and needs.

  • Other forms of magnesium: While magnesium threonate has attracted attention for its potential cognitive benefits, other forms of magnesium also provide various health benefits. Different forms of magnesium have different roles and absorption rates in the body, so the choice of a magnesium supplement should be tailored to your specific health goals.


As with any supplement, it is important to choose products from reputable manufacturers and brands. Additionally, prioritize a balanced diet rich in magnesium-rich foods as part of an overall approach to maintaining good health. If you have existing health conditions or are taking medications, it is especially important to consult with a healthcare professional before starting any new supplement regimen.
