Category: Comparisons
Compare magnesium glycinate and citrate to find the best form for your needs. Learn the key differences in absorption, benefits, and convenience.
Quick answer
Choose magnesium glycinate if you want better absorption and a gentler effect on digestion. Choose magnesium citrate if you need a more affordable option and don't mind a mild laxative effect.
Absorption and bioavailability
Magnesium glycinate is chelated to the amino acid glycine, which enhances absorption and reduces the risk of digestive upset. Magnesium citrate is bound to citric acid and is also well-absorbed, but it can cause a laxative effect in some people.
Convenience and form
Sports Research offers both forms in unflavored options. The 20-packets format (product ID 390776) is ideal for travel or on-the-go use. The 3.9 oz powder (product ID 390775) is a more economical choice for home use. Both mix easily into beverages without altering taste.
Trade-offs at a glance
- Magnesium glycinate: Chelated form with glycine for superior absorption. Less likely to cause digestive discomfort. Often preferred for sleep and relaxation support. Best if you want a gentle, well-absorbed magnesium without laxative effects.
- Magnesium citrate: Bound to citric acid, also well-absorbed. May have a mild laxative effect, which can be helpful for occasional constipation but undesirable for others. Consider if you need a budget-friendly option or want a mild digestive aid.
- Form factor choice: Choose the 20-packets for portability and single-serving convenience, or the 3.9 oz jar for home use. Both are unflavored and mix easily. Match the packaging to your lifestyle: travel vs. home use.
