Magnesium Intake and Depression

There appears to be an association between magnesium intake and depression, whereby a low dietary intake of magnesium is correlated with an increased risk of depression [1]. In fact, it is has been shown that adults with higher magnesium blood levels have a 20% reduced risk of suffering from depression.

Even though were are still uncertain how magnesium works to reduce depressive symptoms, there are several plausible theories available.

Since magnesium ions regulate calcium ion flow in the calcium channels of cells, including neuronal cells, which regulates nitric oxide production, a magnesium deficiency may result in neuronal damage, ultimately causing depression [2].

Furthermore, magnesium has anti-inflammatory properties [3], and since inflammation is associated with depression [4], an increased magnesium intake through high-magnesium foods or supplements may reduce the risk of developing depression. Excess inflammation can adversely affect several hormones in the body, including important mood-regulating neurotransmitters such as serotonin and dopamine.

In addition to the positive anti-inflammatory effects on serotonin production, magnesium is also directly required for serotonin production, meaning that a low magnesium status may impair this function, possibly contributing to depressive symptoms [5].

It is interesting to note that depression affects around 1 in 5 people [6], and a significant portion of the population is estimated to be low in magnesium [7]. Moreover, magnesium supplementation is linked to improvements in depressive symptoms [8].

Conventional treatments for depression include psychological therapies such as cognitive behaviour therapy (CBT) and antidepressant medication. However, both take several weeks to have an effect.  Magnesium supplementation has been shown to have fast antidepressant effects [8], so using magnesium in conjunction with conventional interventions may improve treatment outcomes.

While increasing the intake of foods containing magnesium may have beneficial effects over the long term, supplementation with a high-quality magnesium source is likely to be most effective in the short term.

Using a magnesium plus other mood-boosting nutrients to help reduce depressive symptoms is just one treatment option that is covered in the PI Therapy.
