A reliable, pure glycine supplement from a trusted brand, though higher doses are often needed for noticeable effects on sleep and stress.
This Solgar Glycine product provides a straightforward 500mg of glycine per capsule, a common dosage for individuals looking to supplement this amino acid for various health goals. Solgar is a highly respected brand known for its quality and purity. However, for significant therapeutic effects, especially for sleep or stress relief, doses of 3-5 grams or more are often recommended by nutritionists and seen in clinical studies, meaning multiple capsules would be consumed daily. While the price per serving seems reasonable for a single capsule, the cost can quickly add up for higher daily intake compared to higher-dose glycine products or bulk powders. Online reviews generally praise Solgar's reliability, though some users note the need to take several capsules.
- From a highly reputable and trusted brand (Solgar).
- Pure glycine formulation without unnecessary additives.
- Convenient capsule form for easy dosing.
- 500mg per capsule is a relatively low dose for common therapeutic applications, requiring multiple capsules.
- Price per serving can become less economical when taking higher recommended doses.
- Does not include synergistic co-factors that might enhance benefits for specific goals.
- Individuals taking medications should consult a healthcare professional before use, especially those affecting brain chemistry or blood sugar.
- Glycine can interact with certain psychiatric medications, so medical advice is crucial.
- Pregnant or nursing women and individuals with pre-existing medical conditions should consult a doctor prior to use.

Categories
Glycine 75.0
As a pure glycine product, it fulfills its role as a core glycine supplement. Its score is reflective of its purity and brand reputation, though its dosage per capsule is on the lower side compared to some higher-potency alternatives in the glycine category.
Goals
Digestive Health 70.0
Glycine is a vital component of collagen and plays a role in gut barrier integrity, offering foundational support for digestive health. A 500mg dose contributes to this, but individuals seeking targeted digestive repair might consider combining it with other gut-supportive nutrients or higher glycine intake.
Stress Relief 65.0
Glycine's calming neurotransmitter properties can contribute to stress reduction. While 500mg may offer mild support, more substantial stress-relieving effects typically require higher doses, making this a foundational but not intensely potent option for stress relief.
Sleep Support 65.0
Glycine is known for its ability to improve sleep quality by lowering core body temperature and acting as an inhibitory neurotransmitter. While 500mg can provide some initial support, most research-backed benefits for sleep improvements are seen at doses of 3 grams or more, meaning multiple capsules would be needed.
