Product analysis
IntestiNew centers on glutamine for gut support, with limited support for ongoing bowel symptoms in selected people after an infection. Undisclosed herbs and unspecified ingredient preparations make the full mixture harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
The glutamine and other ingredient preparations are unspecified. The undisclosed herbal contents further limit a confident comparison of preparation quality.
Ingredient Transparency50
Individual nutrient amounts and the herbal blend total are stated. Preparations and the individual herbs are omitted, leaving quantities clearer than the full contents.
Value For Money57
Glutamine offers good value for the amount supplied, while N-acetyl glucosamine is relatively costly. The cost advantage is therefore clearest for shoppers prioritizing glutamine.
Customer Satisfaction91
Customer ratings are very positive across several thousand ratings. The feedback describes satisfaction without establishing effectiveness or safety.
Product Focus40
The gut-related support concerns selected people taking repeated glutamine doses for eight weeks. A single serving does not reproduce that regimen or establish routine gut or immune benefits.

Glutamine · 5000 mgN-Acetyl Glucosamine · 200 mg
Glutamine may help symptoms in a selected group with post-infectious diarrhea-predominant IBS and increased intestinal permeability. The 5 g serving matches one dose in the positive trial, which used three doses daily for eight weeks; a single serving does not establish the same benefit. The saved findings recognize glutamine's amount without establishing routine gut-barrier repair for everyone. Ginger's presence remains unresolved because stored label information and imported ingredient inventory disagree.
How this product is rated for Gut Health
Ingredient fit83
Glutamine provides the recognized connection; ginger's unresolved presence prevents a contribution.
Goal fit
Glutamine fits the selected intestinal-barrier scope, while gamma oryzanol reduces focus.
Dose adequacy
Glutamine receives full saved amount recognition, although the trial used three 5 g doses daily; N-acetyl glucosamine is below threshold.
Pathways59
Intestinal barrier integrity is the only substantially represented route.
Depth
Glutamine supplies the strongest barrier connection, restricted to the selected IBS population in the supplied trial.
Breadth
Only the barrier route reaches substantial coverage.
Evidence79
Glutamine has a positive trial in a specific IBS subgroup, without establishing a general digestive effect.
Evidence strength
Glutamine provides the strongest reviewed support present here, with a narrow population restriction.
Studied preparation
The declared glutamine preparation is recognized.
Formulation logic100
Glutamine works independently, with no matched conflict.
Partner coverage
Glutamine has no missing required partner.
Conflicts
No ingredient conflict is matched.
Effective doses
Glutamine meets the threshold; N-acetyl glucosamine does not, and ginger's presence remains unresolved.
N-Acetyl Glucosamine Not classified
No linked studies yet.
Impact
High effect
Glutamine has a limited connection to immune outcomes through a study using timed drinks after endurance exercise. That regimen and population do not establish routine infection prevention from this product's 5 g serving. The saved findings credit glutamine, but its broader immune benefit remains uncertain. Ginger's imported ingredient presence and amount are unresolved, so it adds no established contribution.
How this product is rated for Immunity
Ingredient fit76
Glutamine is the sole retained ingredient in a formula with other purposes. Its serving reaches the saved comparison, without reproducing the studied exercise regimen.
Goal fit
Glutamine is retained alongside ingredients serving other purposes.
Dose adequacy
The 5 g serving reaches the saved comparison, but does not establish equivalence to timed post-exercise drinks.
Pathways52
The saved findings identify barrier defense alone, based on glutamine; routine adult respiratory benefit remains uncertain.
Depth
Barrier and antimicrobial defense is the strongest saved area.
Breadth
Only barrier defense reaches the saved coverage threshold.
Evidence83
Glutamine drives the evidence finding, with transfer limited by the exercise population and timed regimen.
Evidence strength
The relevant glutamine outcome came from endurance exercise and cannot be generalized to routine adult use.
Studied preparation
The saved preparation finding does not resolve the different population and dosing regimen.
Formulation logic100
Glutamine meets the saved amount threshold without a required partner or configured conflict; this does not establish a general immune dose.
Partner coverage
Glutamine has no missing required partner in the saved findings.
Conflicts
No configured ingredient conflict was identified.
Effective doses
Glutamine meets the saved minimum amount threshold.
