A high-quality but severely underdosed and expensive L-Glutamine supplement (500mg per capsule) from the premium Thorne brand, offering poor value for its stated goals.
Thorne's L-Glutamine product offers 500mg per capsule. While Thorne is widely recognized as a top-tier brand in the supplement industry, celebrated for its exceptional purity, rigorous testing, and professional-grade formulations, this specific product shares the critical limitation of other 500mg glutamine supplements: the dosage is far too low for the stated goals of immunity, fitness, muscle gain, and digestive health. Moreover, at $0.24 per serving, it is significantly more expensive per milligram than its competitors, making it an extremely poor value proposition for achieving therapeutically effective glutamine levels.
- Thorne is a highly respected, professional-grade brand renowned for its exceptional purity, potency, and rigorous third-party testing, ensuring a very high-quality and trustworthy product.
- Ideal for individuals who specifically require micro-dosing or have unique sensitivities, although these scenarios are uncommon for glutamine supplementation.
- The 500mg L-Glutamine dosage is drastically insufficient for the common goals of significant muscle recovery, immune support, or digestive health, which typically require multi-gram doses daily.
- At $0.24 per serving, it is considerably more expensive per milligram of L-Glutamine than other brands, meaning achieving an effective dose would incur an exceptionally high daily cost (e.g., $2.40-$4.80 for 5-10g).
- Consumers will likely find this product to be very expensive and ineffective if they are trying to achieve standard therapeutic benefits of L-Glutamine for fitness, immunity, or gut health due to its minimal dosage per capsule.

Categories
Glutamine 25.0
Despite Thorne's premium quality, the extremely low dosage per serving combined with a high price makes it one of the least value-for-money options within the glutamine supplement category, especially when compared to high-dose powder alternatives.
Goals
Immunity 20.0
While the quality is high, the 500mg dose is far from the multi-gram requirements for meaningful immune support, making it an inefficient and costly choice for this goal.
Fitness 20.0
For significant athletic recovery or performance benefits, L-Glutamine is needed in 5g+ amounts, so this 500mg dose offers negligible impact at a high cost for competitive athletes.
Muscle Gain 20.0
The very low dosage of 500mg is insufficient to provide tangible benefits for muscle anabolism or anti-catabolism, especially when considering the premium price of the product.
