🧂Types of Magnesium

Magnesium is an essential mineral critical for:

  • Energy production (ATP)

  • Muscle function (including heart rhythm)

  • Nerve signaling

  • Bone health

  • Regulating blood sugar and blood pressure

  • Supporting relaxation and sleep

Low magnesium is very common today due to processed foods, stress, and depleted soils.

1. Magnesium Citrate

  • Best For: Constipation relief, mild laxative, muscle cramps

  • Absorption: High

  • Notes: Draws water into the intestines (osmotic effect) to help with bowel movements

  • ✅ Poop help: YES — one of the most effective types for constipation

🧾 2. Magnesium Oxide

  • Best For: Constipation, heartburn, low magnesium levels

  • Absorption: Low

  • Notes: Acts as a laxative in higher doses; less bioavailable for magnesium deficiency

  • ✅ Poop help: YES — helps with constipation but less gentle than citrate

🧾 3. Magnesium Glycinate

  • Best For: Anxiety, sleep, muscle recovery, chronic pain

  • Absorption: High

  • Notes: Bound to glycine (an amino acid); calming and gut-friendly

  • 🚫 Poop help: No — not laxative; easier on the stomach

🧾 4. Magnesium Malate

  • Best For: Fatigue, fibromyalgia, muscle pain

  • Absorption: Good

  • Notes: Often used for energy production and chronic fatigue

  • 🚫 Poop help: Not a laxative

🧾 5. Magnesium Threonate

  • Best For: Cognitive support, brain health, memory

  • Absorption: High (especially into the brain)

  • Notes: Promising for neurological health, not gut-related

  • 🚫 Poop help: No

🧾 6. Magnesium Sulfate (Epsom Salt)

  • Best For: Constipation (oral); sore muscles (bath soak)

  • Absorption: Variable (mostly through skin or as laxative when taken orally)

  • ✅ Poop help: Yes — strong laxative if taken orally; caution with dose

🧾 7. Magnesium Chloride

  • Best For: General supplementation, muscle cramps

  • Absorption: Good

  • Notes: Available in liquid form or topical sprays

  • 🚫/☑️ Poop help: Mild effect, not ideal for constipation

✅ Top Picks for Constipation

  • Magnesium Citrate – gentle and effective; often recommended first

  • Magnesium Oxide – works but may cause cramping

  • Magnesium Sulfate (oral) – very strong; only occasional use

✅ Quick Guide:
- Stress, sleep, anxiety → Magnesium Glycinate or Taurate
- Digestion/constipation → Magnesium Citrate
- Muscle pain/fatigue → Magnesium Malate
- Brain health → Magnesium L-Threonate
- General use → Magnesium Glycinate or Chloride
