Analysis

This product focuses purely on Glycine supplementation, an amino acid crucial for various bodily functions including protein synthesis, neurotransmitter regulation, and collagen formation. At 500mg per serving, it provides a moderate dose of Glycine, which is commonly used to support brain health by promoting calm, reduce stress, aid digestion by supporting gut lining integrity, and notably improve sleep quality by modulating body temperature and acting as a calming neurotransmitter. The inclusion of Vitamin B6 is a beneficial addition, as B6 is a cofactor in many enzymatic reactions, including those involved in neurotransmitter synthesis, potentially enhancing Glycine's effects on mood and brain function.

Pros
  • Provides a good, effective dose of Glycine (500mg) for general use and specific goals.
  • Includes Vitamin B6, which can support neurotransmitter synthesis and overall nervous system health.
  • Excellent price per serving ($0.11) for a pure Glycine product, offering great affordability.
  • High review count (3535) indicates broad user acceptance and consistent satisfaction with the product's efficacy.
Cons
  • The 500mg Glycine dose might be considered low for individuals seeking very strong sleep support, as higher doses (e.g., 3g) are often researched and recommended for significant sleep induction benefits.
Warnings
  • No significant warnings for healthy individuals taking Glycine within recommended doses, but always consult a healthcare professional if you have underlying conditions or are on medications.

Report overview

Categories

This product offers a pure and well-dosed Glycine supplement at 500mg, providing excellent value compared to other standalone Glycine products in the market. It strikes a good balance between efficacy and affordability for general Glycine supplementation, though higher doses exist for specific needs like profound sleep support.

Goals

Glycine's role as an inhibitory neurotransmitter helps calm the nervous system, which is highly beneficial for stress reduction and promoting relaxation. This dosage, combined with B6, makes it a solid and cost-effective choice for promoting a sense of calmness and easing everyday anxiety.
Glycine acts as an inhibitory neurotransmitter in the brain, which can promote calmness and improve cognitive function, while Vitamin B6 further supports overall brain health by aiding neurotransmitter production. The 500mg dose is effective for supporting mental clarity and mood balance for many users, positioning it well among standalone glycine options.
Glycine has been shown to improve sleep quality by lowering core body temperature and promoting faster sleep onset. Although 500mg is on the lower end of clinically studied doses for significant sleep induction, many users find it effective for milder sleep disturbances, and the addition of B6 is a good complement for general neurological support related to sleep.
