Magnesium: simple guide & comparisons
Less fatigue, better muscle function, and bringing your levels up to date. No wild promises: here’s what does work and how to choose fast.
WHAT SHOULD YOU KNOW ABOUT MAGNESIUM?
All these bottles have the same key: magnesium. What changes is the “wrapper” (citrate, bisglycinate, oxide…), which affects how it feels on your stomach and how much your body actually uses.
The essentials, in plain English:
• To raise your levels and feel more energy day to day, citrate or bisglycinate usually work best (often gentler on the stomach).
• For constipation, oxide acts as a mild laxative.
• For migraine, magnesium can help as support (it doesn’t replace your treatments).
• For blood pressure, the effect is small; it helps, but it’s no miracle.
• For cramps, it’s not the best buy.
• To raise your levels and feel more energy day to day, citrate or bisglycinate usually work best (often gentler on the stomach).
• For constipation, oxide acts as a mild laxative.
• For migraine, magnesium can help as support (it doesn’t replace your treatments).
• For blood pressure, the effect is small; it helps, but it’s no miracle.
• For cramps, it’s not the best buy.
How to get it right? Very simple: your goal + real mg of magnesium + how it sits with you. If it bothers your gut, switch the form—don’t give up.
Magnesium types: quick-use guide
“Practical” evidence quality: Works for many people / May help / Don’t buy it for this
| Form | Use it mainly for… | How reliable is it | Pros | Cons | Suggested dose (elemental Mg) |
|---|---|---|---|---|---|
| Citrate | Raising day-to-day levels; “energy” and muscle. Mild laxative. | Works | Good utilization; usually gentle on the stomach. | At higher doses: loose stools. | 200–400 mg/day with meals. |
| Bisglycinate | Raise levels with a calmer stomach. | Works | Very good gut tolerance. | Sometimes pricier. | 200–400 mg/day as you tolerate. |
| Oxide | Bowel movements (laxative). Antacid. | May help | Inexpensive; effective for constipation. | Poorer magnesium utilization; may cause diarrhea. | Titrate to effect (as a laxative). |
| Malate | Alternative for “fatigue”. | May help | Often well tolerated. | Limited specific evidence. | 200–400 mg/day. |
| Chloride | Raising levels (capsules or salts). | May help | Highly available. | Taste and stomach can be more delicate. | 200–400 mg/day in capsules. |

CONCLUSIONS: SIMPLE, EFFECTIVE, NO HYPE
- If you want to feel better day to day, start with citrate or bisglycinate. They’re well-tolerated and well-absorbed.
- If your main goal is bowel movements, choose oxide.
- 200–400 mg of “real” magnesium per day suits most people. If it loosens your stools, lower the dose or switch forms.
- Buy smart: same magnesium, different wrapper. Decide by goal, real daily amount, and how it sits with you.
