From the Research
A low dose magnesium intake is typically considered to be less than 250 mg per day, as deficient intakes at this level have been associated with elevated serum C-reactive protein concentration, a widely used indicator of inflammation, as noted in a study published in 2014 1. When considering magnesium intake, it's essential to understand that magnesium is an essential mineral involved in numerous physiological processes, including energy production, protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation.
- Insufficient magnesium intake can lead to various health issues such as muscle cramps, fatigue, irregular heartbeat, and potentially increased risk of chronic conditions like hypertension and osteoporosis.
- The recommended daily amount of magnesium is approximately 310-320 mg for women and 400-420 mg for men, as suggested by various studies, including one published in 2016 2.
- If you're considering magnesium supplementation, start with a low dose of about 100 mg daily and gradually increase as needed, preferably under healthcare supervision, as excessive intake can lead to hypermagnesemia, which can be a potential threat, especially in individuals with inadequate renal function, as discussed in a study from 1991 3.
- Common supplement forms include magnesium citrate, glycinate, and oxide, with citrate and glycinate generally being better absorbed, and taking magnesium with food can help reduce potential digestive side effects like diarrhea.
- Always consult with a healthcare provider before starting any supplement regimen, especially if you have kidney disease or take medications that might interact with magnesium, as emphasized in a study published in 2010 4 and another in 2018 5.
