Product analysis
Glutamine 300 provides an inexpensive glutamine option, but routine immune benefits remain uncertain. Findings after endurance exercise cannot be assumed to apply to everyday use.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
The glutamine form is not disclosed. That limits a direct comparison of ingredient quality with clearly specified alternatives.
Ingredient Transparency63
The glutamine amount is disclosed, making the serving easy to check. Its unspecified form leaves the preparation less clear.
Value For Money100
The declared glutamine amount offers favourable value in the unit-cost comparison. The low cost does not establish an everyday immune benefit.
Customer Satisfaction76
Customer ratings are generally positive across several hundred reviews. The feedback describes satisfaction without proving immune benefits.
Product Focus83
One active ingredient keeps the formula narrowly focused on glutamine. Evidence from particular post-exercise use does not establish routine immune benefits for everyone.

Goals
Impact
Highest effect
Glutamine has been investigated after endurance exercise, but the timed post-exercise drinks in that study do not establish routine immune benefit from this 4.5 g serving. The saved findings associate it with barrier defense. That association and evidence from severe-illness nutrition do not demonstrate fewer infections in unselected adults.
How this product is rated for Immunity
Ingredient fit97
The formula has a relevant ingredient in the saved findings, but its scientific limitations restrict expectations for routine adult immunity.
Goal fit
The relevant ingredients dominate this formula, although focus alone does not establish a clinical benefit.
Dose adequacy
The declared serving makes a partial contribution against the saved amount comparisons, which are not clinical benefit thresholds.
Pathways50
The strongest assigned area is barrier and antimicrobial defense. These ingredient associations do not establish how much infection risk changes.
Depth
The saved findings emphasize barrier and antimicrobial defense; this describes the assigned ingredient roles rather than proven protection against infection.
Breadth
Coverage is concentrated in one immune area, with limited coverage elsewhere.
Evidence83
The saved evidence finding is positive, but the supplied scientific context limits transfer to routine use in general adults.
Evidence strength
Glutamine leads the saved evidence finding, but the supplied population and regimen limits prevent a routine adult infection-protection claim.
Studied preparation
The saved preparation finding is complete for the included ingredients; it does not establish that this whole product reproduces a clinical regimen.
Formulation logic100
The included ingredients have no missing required partners or configured conflicts. Meeting the saved amount comparisons does not prove a combined clinical benefit.
Partner coverage
No missing required partner limits the included ingredients in the saved findings; this does not demonstrate an added benefit from combining them.
Conflicts
No configured ingredient conflict was identified. This finding does not establish overall safety or cover every possible interaction.
Effective doses
The included ingredients reach the saved minimum amount threshold; this threshold is not proof of a clinically effective immune dose.
Ingredients
| Ingredient | Amount per serving | Score |
|---|---|---|
L-Glutamine | 4500 mg |
Glutamine · 4500 mg OverallScore96
A serving provides 4.5 g of L-glutamine. Allocating the whole-product price to that amount works out to about $0.04 per gram.
How this ingredient is rated
Active Ingredient Quality & Bioavailability100
The saved facts identify L-glutamine and record a qualifying grade claim, but do not specify its name.
Glutamine Grade & Purity
L-glutamine has a recorded grade claim; the exact grade is not identified in the available facts.
Dose, Safety & Label Transparency89
The serving individually declares 4.5 g of L-glutamine.
Therapeutic Dosage Strength
Each serving provides 4.5 g of L-glutamine.
Label Transparency & Blends
The L-glutamine amount is individually stated as 4.5 g per serving.
Value100
Allocating the whole-product price to the L-glutamine amount gives about $0.04 per gram; a whole-product serving costs about $0.18.
Price per Gram of L-Glutamine
The $0.04 per gram estimate attributes the entire whole-product cost to the declared L-glutamine.
