Magnesium is crucial for health and available in different supplement forms such as citrate, glycinate, and oxide. Each option offers unique features. This guide outlines what distinguishes each, how they may help sleep, muscle activity, and nerve function, and shows how to choose the best supplement. You’ll also find dosing advice, potential side effects, and practical usage tips.
Why Your Body Needs This Mineral
It helps with hundreds of functions, like energy production, muscle work, nerve signaling, and keeping bones strong. Most is stored in bones and inside cells. Typical blood tests may not capture total levels. Deficiency might show as tiredness, twitches, or cramps, and can get worse over time.
Rich dietary sources include:
- Pumpkin seeds, almonds, chia
- Leafy greens
- Beans and legumes
- Whole grains
- Dark chocolate
Adult requirements:
- Men: ~400 mg daily
- Women: ~310 mg daily
- Pregnant: ~350 mg daily
Supplements have different actual mineral contents based on their form.
Citrate: Effective, Easily Used
Combined with citric acid for high absorption, this variation is common for addressing constipation or for daily nutrition support. It’s gentle but can occasionally cause cramps or loose bowel movements. Typical daily servings range from 100–350 mg, depending on the purpose.
Avoid large amounts if you have kidney issues or are prone to dehydration:
Dehydration support
Glycinate: Sleep and Relaxation Support
Bonded to glycine, a calming amino acid, this type is less likely to upset digestion and works well for relaxation or sleep. Research suggests benefits for sleep quality. Most take 100–400 mg, ideally in the evening. It’s a comfortable choice for most, but consult your healthcare provider with kidney issues or when using medication.
