Choosing the best magnesium glycinate supplement means looking beyond the number printed on the bottle. The amount of elemental magnesium, the type of magnesium used, additional ingredients, serving size, and overall value all matter. Magnesium glycinate is a form of magnesium bound to glycine and is often chosen by people looking for a supplement that is generally well tolerated.
In this guide, we cover six options, from straightforward magnesium glycinate formulas to multi-ingredient blends, so you can compare their features and find a product that fits your needs.

Pure Encapsulations Magnesium Glycinate is an option for shoppers who prefer a supplement from a brand focused on nutritional products. Its magnesium glycinate formula is designed to provide magnesium without requiring a multi-ingredient relaxation blend.
One important detail when considering this supplement is the difference between the total weight of a magnesium compound and the amount of elemental magnesium it supplies. These figures are not interchangeable, so reviewing the Supplement Facts panel is essential when comparing products.
Key Features
- Magnesium glycinate: Uses a form of magnesium bound to glycine.
- Focused formula: Suitable for shoppers who prefer a magnesium supplement rather than a blend containing several unrelated ingredients.
- Capsule format: Convenient for people who prefer capsules over powders or drink mixes.
- Established supplement brand: Pure Encapsulations offers a range of nutritional supplements, although the exact quality assurances for this product should be checked against its current label and manufacturer documentation.
Best For
People who want a focused magnesium glycinate supplement and prefer to keep their supplement routine simple.
Things to Consider
- Check the current label for elemental magnesium per serving and the number of capsules required.
- Compare the cost per serving rather than judging value by bottle size alone.
- Review the full ingredient list if you have allergies or sensitivities.
2. Sandhu’s Magnesium Glycinate with Quercetin — Best for an Added Antioxidant

- HIGH – GRADE MAGNESIUM SOURCE – Crafted with potent, readily absorbable magnesium to ensure pure and reliable daily nutr…
Sandhu’s Magnesium Glycinate with Quercetin combines magnesium glycinate with quercetin, a plant-derived compound found in various fruits and vegetables. This makes it different from supplements that contain magnesium glycinate alone.
The formula may appeal to people who want both ingredients in one capsule. However, the additional ingredient is not automatically an advantage for everyone, particularly if you already take other supplements.
Key Features
- Magnesium glycinate: The manufacturer lists 400 mg of magnesium glycinate, providing 72 mg of elemental magnesium.
- Added quercetin: Each capsule contains 50 mg of quercetin dihydrate.
- One-capsule serving: The manufacturer’s directions specify one capsule daily, preferably with food, or as advised by a healthcare professional.
- Third-party testing claim: The manufacturer advertises third-party testing for the product.
Best For
People interested in a combination supplement who prefer magnesium glycinate with an additional ingredient rather than a magnesium-only formula.
Things to Consider
- The 400 mg figure refers to magnesium glycinate, not elemental magnesium. The listed elemental amount is 72 mg.
- Check whether quercetin duplicates ingredients in your existing supplements.
- Ask a healthcare professional about possible interactions if you take prescription medicines.
3. Organics Ocean Pure Magnesium Glycinate — Best for a Focused Magnesium Formula
- With Unmatched Chelamax Power: Enjoy 100% of the optimal dose of pure magnesium glycinate with Organics Ocean Magnesium …
- Sourced from the Dead Sea: Our magnesium and zinc are carefully extracted from the most mineral-rich oceans in the world…
- Unrivaled Pure Formulation: Our strict supply-chain monitoring results in a high-absorption, superior formula that’s the…
Organics Ocean Pure Magnesium Glycinate is designed for people who prefer a dedicated magnesium supplement with a relatively short ingredient list. The manufacturer identifies its magnesium ingredient as Chelamax magnesium glycinate and includes a small amount of zinc.
This product stands out because the brand provides a specific elemental magnesium amount rather than relying only on the weight of the magnesium glycinate compound.
Key Features
- 275 mg of elemental magnesium: The manufacturer’s current product information lists this amount per three-capsule serving.
- Chelamax magnesium glycinate: The brand identifies this as its magnesium source.
- Added zinc: The listed serving contains 2 mg of zinc.
- Limited additional ingredients: The manufacturer lists vegetable cellulose capsules and tapioca starch alongside the active ingredients.
Best For
People who want a dedicated magnesium glycinate supplement and are comfortable taking a three-capsule serving.
Things to Consider
- The recommended serving consists of three capsules, not one.
- Check the elemental magnesium amount carefully when comparing it with other products.
- The added zinc may not be necessary if you already obtain enough zinc from food or other supplements.
4. BIOptimizers Magnesium Breakthrough — Best for Multiple Forms of Magnesium
- 7 Forms of Magnesium: Our formula combines 7 types of magnesium, including magnesium glycinate, malate, and citrate, to …
- Balanced Magnesium Levels: As magnesium levels drop, it may affect your body’s rhythm. Our supplement helps replenish an…
- Fast Absorption: Each capsule delivers magnesium in a bioavailable form, designed for easy uptake and use throughout the…
BIOptimizers Magnesium Breakthrough differs from a conventional magnesium glycinate supplement because it combines several forms of magnesium in one formula. These include magnesium bisglycinate, citrate, malate, taurate, orotate, and other forms identified by the manufacturer.
This combination may appeal to shoppers who prefer a multi-form supplement instead of relying on magnesium glycinate alone. However, the product is not a pure magnesium glycinate formula, so it is important to understand what you are purchasing.
Key Features
- Multiple magnesium forms: The original formula is marketed as containing seven forms of magnesium.
- Magnesium bisglycinate: Glycinate is one component of the blend.
- Added vitamin B6: The formula includes vitamin B6.
- Additional minerals and ingredients: Depending on the version, the formula also includes manganese and other ingredients.
Best For
People who specifically want a multi-form magnesium supplement and are comfortable with a more complex ingredient list.
Things to Consider
- This is not a magnesium glycinate-only product.
- The manufacturer has different product versions, so confirm the exact formula and elemental magnesium amount on your bottle.
- The amounts of individual magnesium forms may not be separately disclosed when they are included in a proprietary blend.
5. Dr. Berg Magnesium Glycinate — Best for Added Vitamins and Minerals
- Wake feeling recharged: Includes chelated magnesium glycinate plus D3 and B6, designed to support calm evenings and bala…
- Help your system settle: Formulated with key nutrients that work together to support a sense of relaxation and ease.*
- Keep calm and move well: Magnesium helps maintain normal muscle and nerve function—without harsh laxatives or fillers.*
Dr. Berg Magnesium Glycinate is a combination supplement rather than a formula containing only magnesium glycinate. The manufacturer’s product information lists magnesium alongside vitamin B6, vitamin D3, and zinc.
This combination may be convenient if you specifically want these nutrients together. However, it is important to consider your total daily intake from food and other supplements before adding a multi-ingredient product to your routine.
Key Features
- 120 mg of elemental magnesium per capsule: The manufacturer lists this amount for the current formula.
- Vitamin B6: Included as pyridoxal-5-phosphate in the current product information.
- Vitamin D3: Provides 250 IU per capsule in the current listed version.
- Added zinc: The listed formula includes 10 mg of zinc as zinc picolinate.
Best For
People who want magnesium glycinate alongside vitamin B6, vitamin D3, and zinc in one supplement.
Things to Consider
- The extra nutrients may be unnecessary if you already get sufficient amounts from your diet or other supplements.
- Check the current package because formulations and serving sizes can change.
- Consider the total amount of vitamin B6 and zinc you take from all sources.
6. Double Wood Magnesium Glycinate 400 mg — Best for a Larger Capsule Count
- YOU’RE LIKELY MAGNESIUM DEFICIENT – According to World Health Organization statistics, as much as 75% of the U.S. adult …
- EASY ON THE STOMACH: Magnesium Glycinate is created by bonding the elemental magnesium with the amino acid glycine, resu…
- SIX MONTH SUPPLY: Each capsule contains 400mg of Magnesium Bisglycinate (aka glycinate)*
Double Wood Magnesium Glycinate is a straightforward option for shoppers comparing capsule count, ingredient simplicity, and serving instructions. The supplied product listing identifies 180 capsules and describes the product as magnesium bisglycinate.
One important point is that the advertised 400 mg refers to the magnesium glycinate compound, not necessarily 400 mg of elemental magnesium. These measurements describe different things, and the distinction matters when calculating your daily magnesium intake.
Key Features
- 180 capsules per bottle: A larger capsule count may be convenient for people who prefer buying a supply that lasts longer.
- Magnesium bisglycinate: The product uses a glycinate form of magnesium.
- Vegetarian capsule: The listed ingredients include a vegetable cellulose capsule.
- Additional ingredients: The supplied listing identifies microcrystalline cellulose, organic rice flour, and leucine.
Best For
People who prefer a capsule-based magnesium glycinate product and want to compare larger bottle sizes for value.
Things to Consider
- Verify the elemental magnesium amount on the current Supplement Facts panel before comparing the product with supplements that list elemental magnesium directly.
- Confirm the recommended daily serving, as it may involve more than one capsule.
- Compare the price per serving rather than the price per bottle alone.
How to Choose the Right Magnesium Glycinate Supplement
1. Understand Elemental Magnesium
This is one of the most important factors when choosing a magnesium supplement.
A label may show the weight of the magnesium glycinate compound, the amount of elemental magnesium, or both. These values are not the same. Elemental magnesium is the amount that counts toward your daily magnesium intake.
For example, Sandhu’s lists 400 mg of magnesium glycinate but provides 72 mg of elemental magnesium per capsule. Organics Ocean lists 275 mg of elemental magnesium per three-capsule serving.
Always compare the elemental magnesium amount, not just the largest number on the front of the bottle.
2. Decide Between a Single-Form and Multi-Form Supplement
A single-form product focuses on magnesium glycinate or bisglycinate. This can be a straightforward choice if you want to know exactly which magnesium form you are taking.
A multi-form supplement, such as BIOptimizers Magnesium Breakthrough, combines several magnesium compounds. That means you need to review its full ingredient list and determine whether the additional forms and ingredients fit your needs.
Neither approach is automatically the best choice for everyone.
3. Check Additional Ingredients
Some products include only magnesium and capsule ingredients, while others add vitamin B6, vitamin D3, zinc, quercetin, or other compounds.
Extra ingredients can be useful when they address a specific dietary need, but they can also make it harder to control your intake. Review your existing supplements to avoid unnecessary duplication.
4. Consider Capsule Count and Serving Size
A bottle containing 180 capsules may seem like better value than one containing 90 capsules. However, the daily serving size can differ between products.
Compare:
- Elemental magnesium per serving
- Number of capsules per serving
- Number of servings per bottle
- Price per serving
- Any additional nutrients included
This approach provides a more meaningful comparison than bottle size alone.
5. Review Quality and Testing Information
Look for clear Supplement Facts panels, transparent ingredient information, and credible independent testing when available. A manufacturer statement about testing is useful information to investigate, but it does not automatically establish that every batch meets a particular standard.
Choose a product with labeling you can understand and verify.
6. Consider Safety and Your Daily Intake
Magnesium is an essential mineral involved in muscle and nerve function, energy production, and other normal body processes. However, taking more than you need is not necessarily beneficial.
For adults, the recommended daily magnesium intake from all sources is generally 310–420 mg, depending on age and sex. The US upper limit for magnesium from supplements and medications is 350 mg daily for adults unless a healthcare professional recommends otherwise; this limit does not include magnesium naturally present in food.
Magnesium supplements can interact with certain medicines, including some antibiotics and osteoporosis medications. People with kidney disease may also be at increased risk of magnesium accumulation. Consult a healthcare professional if you have a medical condition, take medication, or are unsure how much magnesium you need.
FAQs
1. What is the best magnesium glycinate supplement?
The right option depends on your needs. Pure Encapsulations is worth considering if you prefer a focused formula, Sandhu’s combines magnesium glycinate with quercetin, and Organics Ocean lists a defined elemental magnesium amount. Compare the current labels before choosing.
2. Is magnesium glycinate the same as magnesium bisglycinate?
The terms are commonly used for the same or closely related magnesium form, in which magnesium is bound to glycine. However, the exact formulation and elemental magnesium content can differ between products, so always check the Supplement Facts panel.
3. Is magnesium glycinate good for sleep?
Magnesium is involved in normal nervous system function, but evidence that magnesium supplements reliably improve sleep in people who are not deficient remains limited. Do not treat a supplement as a guaranteed solution for insomnia or other sleep problems.
4. How much magnesium glycinate should I take daily?
There is no single dose suitable for everyone. The amount depends on your dietary intake, health needs, the supplement’s elemental magnesium content, and professional advice. Follow the product label and ask a healthcare professional before using higher doses.
5. Can you take magnesium glycinate every day?
Many people use magnesium supplements daily when there is a reason to do so, but the appropriate amount depends on individual circumstances. Consider your total intake from food, supplements, and medications, and consult a healthcare professional if you have kidney problems or take medicines that may interact with magnesium.
Conclusion
The best magnesium glycinate supplement is the one that fits your nutritional needs, ingredient preferences, and budget. Pure Encapsulations is worth considering for a focused formula, Sandhu’s offers added quercetin, Organics Ocean lists a defined elemental magnesium amount, and BIOptimizers provides a multi-form blend. Dr. Berg adds other nutrients, while Double Wood offers a larger capsule count.
Before buying, check elemental magnesium per serving, the number of capsules required, additional ingredients, and quality information. These details will help you make a more informed choice without relying solely on front-label claims.
