Sports Research Magnesium Glycinate 160mg – 180 Vegan Capsules

Sports Research® Magnesium Glycinate delivers 160 mg of chelated elemental magnesium per serving in a convenient vegan capsule format (180 count). The magnesium glycinate (bisglycinate) chelate form is well-absorbed and gentle on the digestive system, making it suitable for sleep, calm, muscle relaxation, and stress support.

Key attributes:

• Pure chelated magnesium glycinate, no magnesium oxide filler
• Vegan capsules (plant-based)
• Moderate elemental dose at ~160 mg per capsule
• Reasonably priced at ~$0.17 per serving (or $0.15 with Subscribe & Save)
• No third-party testing certifications (USP/NSF/ConsumerLab) publicly stated
• Standard excipients; generally well-tolerated

Customer feedback is consistently positive across Amazon, with users praising the gentle formulation and effective sleep/relaxation support. A few note the capsule size, but overall reports of GI upset are minimal. Sports Research is a recognized supplement brand with decent retail presence and community trust, though not in the "clinician-preferred" tier of Pure Encapsulations or Thorne.
