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.

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.

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.

This makes it an excellent choice for those who experience digestive discomfort with standard magnesium supplements.

Always consult with a healthcare provider before starting a new supplement, especially if you take medications or have underlying conditions.

This form of magnesium is uniquely designed to cross the blood-brain barrier, which is crucial for supporting cognitive functions like memory, focus, and learning.
