Why Magnesium Matters in Everyday Health
Why Magnesium Matters in Everyday Health
Magnesium supports many essential processes in the body, but some people may not meet their daily needs through diet alone.
Modern eating patterns that rely heavily on refined and processed foods can be lower in natural magnesium compared to whole foods such as leafy greens, nuts, seeds and legumes.
Increased physical demands, such as exercise, physically demanding work, or periods of stress, may also increase the body’s use of magnesium. Dietary magnesium, ideally obtained through a balanced and varied diet, should form the foundation of healthy intake.
Magnesium supplements may be used to support dietary intake where nutritional intake is inadequate.
