- Promotes restful sleep and relaxation, backed by GABA-stimulating properties.
- Free from common allergens like soy and gluten, plus verified non-GMO.
- Vegan capsules and cGMP-compliant manufacturing for clean, reliable production.
- Positive customer feedback with a high rating, indicating satisfaction.
Cons
- 160mg per capsule may be lower than some other magnesium supplements, requiring multiple capsules for higher doses.

Sports Research Magnesium Glycinate is a high-quality supplement designed for individuals seeking to improve their sleep quality and overall relaxation. This product is ideal for adults who struggle with occasional sleeplessness or feel the need for a natural way to unwind after a long day. Its formulation focuses on delivering magnesium in a form that the body can easily absorb, making it a standout choice in a crowded market.
The standout feature is its chelated magnesium glycinate, which is known for superior absorption compared to non-chelated forms. This means your body can more effectively utilize the 160mg per serving, potentially enhancing its calming and sleep-supporting benefits. The inclusion of GABA stimulation further aids in relaxation, helping you fall asleep faster and enjoy deeper rest.
In terms of design and quality, Sports Research maintains a high standard. The vegan capsules are easy to swallow and free from soy, gluten, and GMOs, catering to various dietary preferences. The product is made in cGMP-compliant facilities in the USA, ensuring rigorous quality control. The 90-count bottle provides a 90-day supply at 160mg per serving, offering good value for daily use.
While the product excels in many areas, a potential drawback is the dosage per capsule. At 160mg, some users may need to take more than one capsule to reach their desired daily intake, which could be inconvenient. Additionally, the product currently has limited reviews, so long-term efficacy is not yet fully established. However, the existing ratings are overwhelmingly positive, suggesting a reliable performance.
Overall, Sports Research Magnesium Glycinate is a trustworthy choice for anyone looking to enhance their sleep and relaxation naturally. Its superior absorbability, clean ingredient profile, and commitment to quality make it a worthwhile addition to a daily wellness routine. I recommend it to those who prioritize effective, high-quality supplementation.
Pros
- Chelated magnesium offers better absorption than non-chelated forms
- Includes coconut MCT oil and sunflower lecithin to further enhance nutrient uptake
- Vegan and non-GMO options available, catering to various dietary preferences
- Promotes relaxation and sleep without causing grogginess
- Made in the USA with rigorous quality control
Cons
- Coconut MCT oil may not be suitable for those with coconut allergies

Sports Research Magnesium Glycinate with Coconut MCT Oil is a thoughtfully formulated supplement designed to support relaxation and restful sleep. The chelated magnesium glycinate is bound to an amino acid for enhanced absorption, and the addition of coconut MCT oil and sunflower lecithin further boosts bioavailability, making it more effective than many standard magnesium supplements.
This product is ideal for individuals who struggle with sleep, muscle cramps, or stress, and who prefer clean, non-GMO ingredients. Each serving delivers 160 mg of elemental magnesium, which is a moderate dose that can be easily adjusted by taking multiple capsules if needed. The softgel form is comfortable to swallow and the absence of soy and gluten makes it suitable for many dietary restrictions.
In terms of design and build quality, Sports Research maintains strict quality standards, manufacturing in cGMP-compliant facilities in the USA. The product is IGEN non-GMO tested, offering peace of mind for health-conscious consumers. The vegan capsule and liquid softgel options provide flexibility, though the liquid softgel contains coconut MCT oil, which may be a concern for those with coconut allergies.
While the magnesium dose per serving is on the lower end, this can be an advantage for users who want to control their intake or take it alongside other supplements. The primary drawback is the lack of extensive customer reviews, as this appears to be a newer addition to the market. However, based on the ingredients and formulation, it shows strong potential for those seeking a high-quality magnesium supplement.
Overall, Sports Research Magnesium Glycinate with Coconut MCT Oil is a well-designed product that prioritizes absorption and purity. It is an excellent choice for anyone looking to support their sleep and relaxation routine with a clean, effective supplement.
Pros
- Highly absorbable form of magnesium with minimal GI side effects
- Third-party tested for purity and potency
- Large 360-capsule bottle offers exceptional value
- Manufactured in a GMP-certified facility
- Flexible dosing options to fit individual needs
Cons
- Requires taking 3 capsules per serving, which may be inconvenient for some
- Limited flavor or variety (available only in capsule form)
- No added probiotics or complementary nutrients
Nutricost Magnesium Glycinate Capsules offer a practical solution for those seeking to boost their magnesium intake without the digestive issues often associated with other forms. Each serving of three capsules provides 210mg of elemental magnesium from magnesium glycinate, a chelated form known for its excellent absorption and gentle effect on the stomach. This product is ideal for individuals looking to support muscle function, nerve health, and relaxation, especially those who experience digestive discomfort with magnesium oxide or citrate.
One standout feature is the commitment to quality: the capsules are manufactured in an NSF-certified, GMP-compliant facility, and each batch is third-party tested for potency and purity. This gives users confidence that they are getting a consistent, high-quality supplement. The 360-count bottle offers a generous 120-day supply, making it an economical choice for daily use. The capsules themselves are easy to swallow and have no aftertaste, which adds to the user-friendly experience.
In terms of real-world performance, users report noticeable improvements in sleep quality, muscle recovery, and overall calmness. The gentle absorption means fewer laxative effects compared to cheaper magnesium forms, which is a significant advantage for long-term supplementation. The flexible sizing options (90, 180, and 360 capsules) allow customers to choose the quantity that best fits their lifestyle, though the largest size offers the best value per dose.
A potential drawback is the need to take three capsules per serving, which might be a minor inconvenience for those who prefer one-pill solutions. Additionally, the product is unflavored and in standard capsule form, so it lacks any added taste or functional ingredients like probiotics. However, for a straightforward, high-potency magnesium supplement, these are minor trade-offs.
Overall, Nutricost Magnesium Glycinate Capsules deliver on quality, value, and efficacy. With a stellar rating and a price point that undercuts many competitors, this is a top recommendation for anyone needing a reliable magnesium source without stomach upset. Whether you are an athlete, a busy professional, or someone managing stress, this supplement is a smart addition to your daily regimen.
Pros
- Highly absorbable chelated form maximizes effectiveness
- Advanced formula with MCT oil and lecithin boosts absorption
- Clean ingredients: soy-free, gluten-free, non-GMO

Sports Research Magnesium Glycinate is a premium supplement designed for individuals seeking better sleep quality and relaxation. Each softgel provides 160 mg of chelated magnesium, a form known for its superior absorption compared to standard magnesium oxide or citrate. This makes it an excellent choice for anyone who struggles with restless nights or wants to support a calm nervous system without the digestive upset often linked to other magnesium types.
What sets this product apart is its innovative blend of coconut MCT oil and sunflower lecithin, which work together to further enhance the bioavailability of magnesium. Users appreciate the gentle yet effective support for winding down at night, as the chelated magnesium helps stimulate GABA, a key neurotransmitter for relaxation. The 60-count supply offers a convenient month's worth of daily support.
The softgels are designed with quality in mind: the brand uses cGMP-compliant facilities in the USA, and the product is tested non-GMO by IGEN, as well as being free from soy and gluten. The liquid softgel form may provide faster absorption for some users, though the softgels are slightly larger than average, which could be a minor inconvenience for those with difficulty swallowing pills.
One potential drawback is the inclusion of coconut MCT oil, which may not be suitable for individuals with coconut allergies. Additionally, at 160 mg per serving, users who require a higher daily magnesium intake might need to take multiple softgels, so checking your personal needs is advisable. However, for most people, this strength aligns well with general dietary supplementation.
Overall, Sports Research Magnesium Glycinate stands out as a well-formulated, highly absorbable magnesium supplement that genuinely supports restful sleep and relaxation. Its clean ingredient profile and commitment to quality make it a trustworthy choice for health-conscious buyers.

Sports Research Magnesium Glycinate is a premium supplement designed for those seeking better sleep and improved relaxation. Each serving delivers 160 mg of chelated magnesium glycinate, a form known for its high absorption and gentle effect on the stomach. This product is ideal for adults who struggle with occasional sleeplessness or want to support their nervous system naturally.
The standout feature is the chelation process, which binds magnesium to the amino acid glycine. This enhances bioavailability, meaning your body can use more of the mineral per dose. Users often report feeling calmer and falling asleep more easily, thanks to the glycine's role in promoting GABA, a neurotransmitter that quiets the mind.
Design and build quality are top notch. The capsules are vegan, free from soy and gluten, and the supplement is IGEN non-GMO tested. Sports Research manufactures in cGMP compliant facilities in the USA, ensuring consistent purity and potency. The 180 count bottle provides a three month supply at the recommended serving size.
One potential drawback is the dosage: 160 mg is modest compared to some other magnesium supplements that offer 200 mg or more per capsule. Those with severe deficiencies may need to take multiple capsules. Also, the price is slightly above average, but the quality and clean ingredient list justify the cost for many users.
Overall, Sports Research Magnesium Glycinate is a reliable choice for anyone wanting a high absorption, clean label magnesium supplement with proven sleep support benefits. It earns a strong recommendation for its efficacy, transparency, and commitment to quality.

Buying Guide
Absorption and Bioavailability
Magnesium glycinate is prized for its high absorption and gentle effect on the stomach. Sports Research goes a step further by adding sunflower lecithin and coconut MCT oil to their softgel forms, which may enhance uptake. Nutricost uses a standard chelated glycinate without extra absorption aids. If maximum bioavailability is your priority, Sports Research offers a more advanced delivery system.
Serving Size and Potency
Each brand provides different elemental magnesium per serving. Sports Research capsules and softgels contain 160 mg of magnesium per serving (2 capsules or 2 softgels). Nutricost delivers 210 mg per serving (3 capsules), giving you a higher dose in a single serving. For those who want a stronger nightly dose, Nutricost may be more convenient. However, Sports Research makes it easy to adjust by offering 60, 90, 120, and 180-count bottles.
Form and Convenience
Sports Research offers both vegan capsules and liquid softgels with MCT oil. The softgels are a good choice if you prefer a liquid center and added fats for absorption. Nutricost only provides standard capsules, but they come in three bottle sizes (90, 180, 360 capsules). If you want to stock up for months, Nutricost’s 360-count bottle is hard to beat.

Final Thoughts
Choosing between Sports Research and Nutricost depends on your personal priorities. If you value a premium formula with added absorption enhancers like MCT oil and want flexible serving sizes, Sports Research Magnesium Glycinate w/Coconut MCT is an excellent choice. On the other hand, if you need a higher dose per serving and prefer a larger supply to last months, Nutricost Magnesium Glycinate Capsules (210mg) offers outstanding value and convenience. Both will support restful sleep and muscle relaxation.
