Best Magnesium Glycinate on iHerb (2026): Top Picks for Sleep, Stress & Muscle Recovery

Magnesium is one of the most common “missing minerals” in modern diets—and it’s heavily involved in relaxation, muscle function, nerve signaling, and normal sleep quality. But not all magnesium supplements feel the same: some forms are more likely to upset your stomach, while others are gentler and better tolerated.

If you’re shopping on iHerb and want a high-quality, gentle magnesium option, magnesium glycinate (often labeled magnesium bisglycinate) is one of the best places to start. This guide compares the best magnesium glycinate supplements on iHerb, explains how to choose the right one, and shows you what actually matters on the label.

Why Magnesium Glycinate is a top choice

Magnesium glycinate is magnesium bound to glycine, an amino acid often associated with calming effects. Compared to forms like magnesium oxide, glycinate/bisglycinate is typically:

• Gentler on digestion (less likely to cause diarrhea than some forms)
• Popular for sleep and relaxation
• Great for long-term daily use for many people

How to choose the best magnesium glycinate (label checklist)

Before buying, check these:

1. Elemental magnesium per serving
   • Look for “Magnesium (as magnesium bisglycinate)” and note the milligrams.
2. Serving size & pills per serving
   • Some products require 2–4 capsules to hit the listed dose.
3. Form transparency
   • Prefer brands that clearly state glycinate/bisglycinate and don’t hide it in “proprietary blends.”
4. Additives
   • If you’re sensitive, choose fewer fillers (especially artificial dyes or unnecessary binders).
5. Your goal
   • Sleep/stress support vs. athletic recovery vs. general wellness.
