Magnesium never gets center stage. Sodium always plays the villain. Potassium is usually the hero. Magnesium — who is that? Well it may be time to write in magnesium as the superhero. Studies have shown that this no-name mineral can improve the following health conditions:
- Heart irregularities
- Bone strength
- Premenstrual syndrome (PMS)
- Muscle function
This mineral is also commonly used to treat constipation since it can power up the intestines.
How do you know if you are getting enough magnesium? A simple blood test can give a rough estimate of your level of magnesium.
What are risk factors for magnesium deficiency?
- Diuretics (water pills) cause loss of magnesium as well as potassium through the kidneys
- Alcohol abuse can lead to magnesium deficiency
- Intestinal malabsorption
- Chronic use of stomach acid-lowering drugs may cause low magnesium
- Poor diet of mostly processed foods
What are food power sources of magnesium?
Green leafy vegetables, whole grains, fish, beans and nuts are sure to boost up your magnesium supply.
