- 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
- Highly absorbable chelated form maximizes effectiveness
- Advanced formula with MCT oil and lecithin boosts absorption
- Clean ingredients: soy-free, gluten-free, non-GMO
- Trusted brand commitment to quality and purity
Cons
- Softgels may be larger and harder to swallow for some users
- Contains coconut MCT oil, not suitable for those with coconut allergies
- Limited to 160 mg per serving, may require multiple capsules for higher doses
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. If you value superior absorption and a formula built for efficacy, this product is a solid investment in your nightly routine.

Buying Guide
Form and Absorption
When choosing a magnesium supplement, the form matters greatly for absorption and tolerability. Both Thorne and Sports Research use chelated forms, meaning the magnesium is bound to an amino acid for better uptake. Thorne offers Magnesium Bisglycinate in a powder form, which allows for flexible dosing and quick absorption. Sports Research provides Magnesium Glycinate in both vegan capsules and softgels with coconut MCT oil, which may enhance absorption further.
Consider your preference: powders mix easily into drinks, while capsules and softgels are convenient for travel. Softgels with MCT oil can be a good option if you also want a small energy boost.
Sleep and Relaxation Support
Both supplements are designed to promote restful sleep by supporting GABA activity and muscle relaxation. Thorne’s formula emphasizes whole-body wellness and is NSF Certified for Sport, making it a trusted choice for active individuals. Sports Research highlights its ability to stimulate GABA for relaxation and sleep.
If sleep is your primary goal, either works well, but the powder form of Thorne may be easier to adjust for personalized dosing. For a broader approach to relaxation, you might also explore ashwagandha and magnesium for sleep.
Quality and Certifications
Quality assurance is critical for supplements. Thorne is NSF Certified for Sport, meaning it is verified for label accuracy and free from banned substances, a gold standard for athletes. Sports Research supplements are made in cGMP-compliant facilities and are IGEN non-GMO verified. Both brands commit to high manufacturing standards, but Thorne’s certification may appeal more to competitive athletes.
If you prioritize third-party certification, Thorne’s NSF status is a standout feature. For most users, Sports Research offers excellent quality at a more accessible price point.
Serving Size and Dosing Flexibility
Thorne’s powder provides 60 servings per container, allowing you to adjust the dose easily (typically 1 scoop per serving). Sports Research capsules and softgels come in fixed 160 mg servings per capsule, which is convenient but less flexible. If you prefer a set routine, capsules are ideal; if you want to fine-tune your intake, the powder wins.
Consider your daily habits: powders require mixing, while capsules are grab-and-go. Both are effective, but your lifestyle will dictate the best choice.
Final Thoughts
Choosing between Thorne and Sports Research boils down to your priorities. For athletes and those who value rigorous certification, THORNE Magnesium Bisglycinate offers a versatile powder with NSF certification, ideal for customizable dosing and overall wellness. For everyday users seeking a convenient, high-quality capsule, Sports Research® Magnesium Glycinate 160mg provides excellent absorption and sleep support at a great value. Both are excellent choices, so pick the one that fits your routine best.
