Score 55.0

A Solgar L-Glutamine supplement providing 2000mg per serving. While from a reputable brand and better dosed than 500mg options, it may still require multiple servings for optimal results.

Analysis

Solgar's L-Glutamine product delivers 2000 mg per serving (likely two 1000 mg tablets). While this dosage is an improvement over the common 500mg options, it still typically falls short of the 5-20 grams per day generally recommended by nutritionists for significant effects in muscle recovery, immune function, or digestive health. Solgar is a highly respected brand, known for its commitment to quality and purity, which adds to its appeal. However, the tablet form and still modest dosage mean that multiple servings would be necessary to reach effective levels, affecting convenience and overall daily cost.

Pros
  • Solgar is a premium brand with a long-standing and excellent reputation for high-quality, purity, and rigorous testing, providing a strong assurance of product integrity.
  • The 2000mg per serving is a significantly higher dose compared to 500mg standard capsules, making it a more practical starting point for reaching effective daily intake, though still requiring multiple doses for significant impact.
Cons
  • Despite the 2000mg dose, it remains below the typically effective daily range of 5-20g for the specified goals, necessitating multiple servings which can become cumbersome and add to daily pill count.
  • The price per serving ($0.37 for 2000mg) is relatively high compared to bulk L-Glutamine powder, making it less economical for consistent, high-dose usage over time.
Warnings
  • To achieve substantial benefits for muscle, immunity, or gut health, consumers will likely need to take several servings daily, potentially exceeding the product's recommended usage and significantly increasing overall daily cost.

Report overview

Categories

This product stands out among capsule options by offering a higher dose per serving and coming from a highly reputable brand, making it a more viable, though still not optimal, choice within the glutamine category compared to high-dose powders.

Goals

While 2000mg offers some support, robust immune system function often benefits from 5-10g or more of L-Glutamine daily, meaning multiple doses are still necessary for tangible effects.
For post-exercise recovery and minimizing muscle breakdown, L-Glutamine is typically dosed at 5g+, so 2000mg per serving provides only partial support for active individuals.
The contribution of L-Glutamine to muscle protein synthesis and anti-catabolic effects is more pronounced at higher gram-level doses, making 2000mg a supportive but not primary dose for muscle gain.
