- Free from common allergens like soy and gluten, plus verified non-GMO.
- Vegan capsules and cGMP-compliant manufacturing for clean, reliable production.

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.

THORNE Magnesium Glycinate is a premium supplement designed for individuals seeking optimal magnesium absorption without gastrointestinal discomfort. This product is ideal for those who struggle with sleep quality, muscle tension, or stress, as well as athletes looking to support recovery.
The standout feature is its chelated form: magnesium bound to the amino acid glycine. This enhances bioavailability and reduces laxative effects common with other magnesium types.

Thorne's manufacturing adheres to strict quality controls, including third-party testing for purity and potency. The capsules are free from common allergens and artificial ingredients, making them suitable for sensitive individuals. While the bottle contains 90 capsules, the recommended dosage typically ranges from one to three per day depending on individual needs.
Potential drawbacks include a higher cost per serving versus generic brands, and the need for multiple capsules to achieve 400 mg of elemental magnesium.

Buying Guide
Absorption and Form
Magnesium glycinate is chelated, meaning the mineral is bound to the amino acid glycine for better absorption. Both Thorne and Sports Research use this form, but Sports Research emphasizes their chelated process for superior bioavailability. Thorne’s Magnesium Bisglycinate also uses a well-absorbed bisglycinate form. When choosing, look for chelated magnesium on the label to ensure your body can use it effectively.
Formulation and Additional Ingredients
Sports Research offers two versions: a standard vegan capsule and a softgel with coconut MCT oil and sunflower lecithin to further aid absorption. Thorne provides a standalone magnesium glycinate capsule and a Sleep Support Duo that pairs magnesium bisglycinate with Melaton-3 for those needing help with sleep and jet lag. If you prefer a simple magnesium supplement, the capsule forms work well. For a sleep-focused option, Thorne’s duo is worth considering.
