There are several types of magnesium supplements, each suited for different health needs:

• Magnesium glycinate (or bisglycinate): Highly bioavailable, calming, and gentle on the stomach. Good for sleep support, stress relief, and nervous system regulation.
• Magnesium citrate: Well absorbed and often used for improving digestion and treating constipation. Also supports general magnesium levels.
• Magnesium oxide: Common but poorly absorbed; typically used as a laxative but can be harsh on the gut.
• Magnesium sulfate (Epsom salts): Used mainly topically for muscle relaxation and stress relief.
• Magnesium L-threonate: Supports brain health, cognition, and mood.
• Magnesium malate: Energizing form, helps with fatigue and pain.
• Magnesium taurate and orotate: Beneficial for heart health.
• Magnesium chloride: Often used in liquid or topical form for general supplementation.

The best magnesium depends on individual needs:

• For sleep and relaxation: magnesium glycinate or bisglycinate.
• For constipation: magnesium citrate or oxide (with oxide being harsher).
• For brain health and cognition: magnesium L-threonate.
• For muscle relaxation and stress relief: magnesium sulfate or glycinate.
• For energy and chronic pain: magnesium malate.

Trying different forms helps find what works best for personal health goals and tolerance.
