Is Magnesium Needed to Metabolize the Hormone Cortisol?

Magnesium regulates cortisol levels.

Cortisol is the "fight or flight" steroid hormone released to stimulate the body during stressful times. In excessive amounts, it is harmful to health. Magnesium is known as the antistress mineral for its ability to regulate cortisol levels.

Magnesium and Stress

Magnesium and stress are inextricably linked in a vicious cycle. While stress depletes magnesium levels, a magnesium deficiency can exacerbate the symptoms of stress.

Function

Magnesium supports adrenal health and regulates cortisol levels. While abundant magnesium will not affect normal levels, a deficiency of magnesium will allow high levels of cortisol to linger for longer than necessary

Significance

Cortisol increases blood sugar levels in response to stress. Magnesium counteracts the hormone by stabilizing blood sugar levels, decreasing the possibility of insulin resistance and consequently preventing the body from weight gain.

Sources

Green leafy vegetables, whole grains, nuts and seeds are rich sources of magnesium. Supplemental magnesium may be recommended by a physician for individuals suffering from stress-related disorders such as anxiety and panic attacks.

Considerations

Caffeine and alcohol can deplete magnesium levels in the body. Avoiding or consuming them moderately during stressful periods may help the body deal better with the detrimental effects of high cortisol.
