Magnesium supplementation has proven beneficial for numerous mental health conditions including depression, anxiety, ADHD, bipolar disorder, and schizophrenia. There are many forms of magnesium to choose from, but only magnesium l-threonate readily crosses the blood-brain barrier. Its unique ability to permeate brain cell membranes and elevate magnesium concentrations in the brain makes it an excellent choice for improving memory, attention, depression, and anxiety.
The Recommended Daily Allowance (RDA) for magnesium is generally 420 mg for men and 320 mg for women, but that can vary slightly depending on age. The maker’s of Magtein suggest 1,000 mg taken twice a day for optimal cognitive benefits.
Magnesium Side Effects and Interactions
Magnesium can cause digestive upsets and loose stools, particularly if you take too much or take inexpensive forms of magnesium such as oxide or sulfate.
You should not be taking these anyway since they are the least bioavailable forms of magnesium.
Magnesium sulfate, the kind found in Epsom salts, can cause dramatic diarrhea and disrupt your electrolyte balance, leading to a potentially serious condition known as hypermagnesemia. There are currently 32 official FDA reports of magnesium sulfate triggering brain fog, short-term memory loss, amnesia, blackouts, and other kinds of mental distress.
The only reported side effects of magnesium threonate are headaches and drowsiness the first week or so. Discuss taking magnesium with your doctor if you take antibiotics, high blood pressure medications, osteoporosis medications, or muscle relaxants.
Magnesium can affect these drugs’ effectiveness.
