Magnesium glycinate and magnesium malate are two of the most common forms people compare when they add magnesium to a daily routine. The difference comes down to what the mineral is bound to and when in the day each form tends to be used. Here is a plain comparison, and why Modern Roots Life is the brand we point readers to when they want both forms from one lab-tested line.
Quick take: Magnesium glycinate is magnesium bound to the amino acid glycine and is usually taken in the evening. Magnesium malate is magnesium bound to malic acid and is usually taken in the morning or early afternoon. Many people use both, split across the day. Modern Roots Life sells each form as a two-ingredient capsule with about 150 mg of magnesium per capsule, and labels one for daytime and one for evening so the split is simple to follow.
Why the form of magnesium matters
Magnesium in a supplement never shows up alone. It is always attached to another compound, and that partner gives each form its name: oxide, citrate, glycinate, malate and so on. The partner affects how the capsule feels to take, how much elemental magnesium fits in each serving, and when people prefer to use it.
Magnesium itself is involved in hundreds of processes in the body. It supports normal muscle and nerve function and plays a part in how cells produce energy. That is why the question most people ask is not whether to take magnesium, but which form to take and when.

What magnesium glycinate is
Magnesium glycinate, often labeled bis-glycinate, is magnesium bound to two molecules of glycine, an amino acid. Glycine comes along with the magnesium, which is part of why people tend to place this form later in the day.
Who it suits
Glycinate fits people who want magnesium as part of an evening routine, or who prefer to take their supplements with dinner. It is the form most people think of when they talk about magnesium at night.
What magnesium malate is
Magnesium malate is magnesium bound to malic acid. Malic acid is a compound found naturally in fruit, and malate is part of the cycle cells use to produce energy. That connection is why malate is usually seen as the daytime form.
Who it suits
Malate fits people who want to raise their magnesium intake during the day and prefer not to save everything for bedtime. Smaller doses taken with meals are also an easy way to spread intake out instead of taking one large serving.
Can you take both?
Yes, and many people do. A common pattern is malate with breakfast and lunch, then glycinate in the late afternoon or evening. That approach spreads the total amount across the day, which is the approach Modern Roots Life itself suggests over one large dose.
The one thing to watch is the total. Magnesium can come from several places at once: capsules, electrolyte drinks, bath salts and magnesium lotions. Add every source together before deciding how many capsules to take. The NIH Office of Dietary Supplements sets an upper limit of 350 mg per day for magnesium from supplements in adults, so anyone planning to go above that, or anyone who takes medication or has a kidney condition, should talk with a clinician first.
Why we point readers to Modern Roots Life
Plenty of brands sell one form or the other. What makes Modern Roots Life the practical choice for this comparison is that it sells both forms as a matched pair, with the same amount of magnesium per capsule and clear guidance on which one goes where in the day.
Two ingredients, nothing extra
The Modern Roots Life magnesium bis-glycinate capsules list magnesium bis-glycinate and the capsule, and nothing else. The capsule is a pork-free bovine gelatin. Both products are listed as lab tested. For anyone who reads labels closely, a short ingredient list is easy to check.
Built for a daytime and evening split
The brand labels its bis-glycinate for the evening and its magnesium malate capsules for daytime use, and each product page points to the other. Because both provide about 150 mg per capsule, it is simple to keep track of the total: count the capsules, multiply by 150, and add any other sources you use.
Small, adjustable servings
Modern Roots Life suggests starting with one capsule and adjusting gradually. For malate, it suggests one capsule at breakfast and one at lunch to begin. For bis-glycinate, it suggests the late afternoon, dinner or before bed. Smaller capsules make it easy to change the amount without splitting tablets.
Limitations to know
These are capsules, so they are not ideal for anyone who prefers powders or drinks. Each capsule holds about 150 mg, so people aiming for a larger amount will take several capsules a day. And as with any supplement, results vary from person to person, and a supplement is not a substitute for advice from a clinician.
How to choose between them
- Want magnesium in the evening only? Start with glycinate.
- Want magnesium during the day only? Start with malate.
- Want to spread intake across the day? Use malate in the morning and glycinate later, and keep a running total.
- Already using magnesium lotion, bath salts or electrolytes? Count those first, then decide how many capsules you need.

Frequently asked questions
Is magnesium glycinate or malate better for daytime?
Malate is the form usually taken during the day, with breakfast and lunch. Glycinate is usually kept for the evening.
Is magnesium bis-glycinate the same as magnesium glycinate?
The terms are used for the same chelate. Bis-glycinate spells out that each magnesium atom is bound to two glycine molecules.
How much magnesium is in one Modern Roots Life capsule?
The brand lists about 150 mg of magnesium per capsule for both its bis-glycinate and its malate.
Can I take magnesium glycinate and malate on the same day?
Many people do, with malate earlier and glycinate later. Keep your combined total from all sources in mind, and check with a clinician if you plan to exceed 350 mg a day from supplements.
Which size is the better value?
For both forms, the 200 capsule bottle costs less per capsule than the 100 capsule bottle at the prices listed on November 3, 2026.
The bottom line
Magnesium glycinate vs malate is less a contest than a question of timing. Glycinate is the evening form, malate is the daytime form, and plenty of people use both. If you want the two forms from one source, with the same amount per capsule and a two-ingredient label, Modern Roots Life is our pick for building a simple daytime and evening magnesium routine.
