The researchers of the following study examined the effects of magnesium (Mg) supplementation on C-reactive protein (CRP) levels, a marker of inflammation (Mazidi M, et.al., 2018).
They conducted a systematic review and meta-analysis of randomized controlled trials and found that Mg supplementation led to a significant reduction in CRP levels.
The reduction in CRP levels were found with a variety of dosages and duration of Mg supplementation. These findings suggest that Mg can help reduce inflammation.
When using magnesium choose an amino acid chelate like magnesium glycinate which has shown to be better absorbed than magnesium oxide. This form does not irritate the gastrointestinal tract either which magnesium oxide may do.
