Research has shown that magnesium deficiency is associated with symptoms of mood disorders such as anxiety, depression and bipolar disorder. A lack of magnesium seems to reduce levels of serotonin, and magnesium has been proven to be effective in treating depression.
Although magnesium is found in many foods, most people most likely don’t get enough magnesium from their diet. The RDA for magnesium is 320mg to 420mg daily, and the average intake is only about 250mg daily. Some health conditions can also interfere with the body’s magnesium balance, as well as other factors such as age, excessive alcohol intake or chronic stress.
