Colostrum and L-Glutamine: what the published research says
PubMed indexes 4 records that name Colostrum and L-Glutamine together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Colostrum and L-Glutamine. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.

The research
4 studies naming Colostrum and L-Glutamine.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“This study suggested that the combined administration of bovine colostrum and glutamine might effectively reduce NSAID-induced gut damage and BT in the rat.”
Names both Colostrum and L-Glutamine in its title.
Randomized Controlled Trial, VeterinaryAnimal study
“Ultimately, piglets from sows supplemented with Gln/Glu had higher weaning weights compared with the control group. Our results suggest that Gln/Glu supplementation in sow diets may improve the farrowing process, enhance the nutritional quality of colostrum, and improve piglets’ weaning weight, even if it doesn’t drastically change all sow performance measures.”
Names both Colostrum and L-Glutamine in its title.
In vitro cellular & developmental biology : journal of the Tissue Culture Association · 1986 · PMID 2872199
Animal study
“To obtain information on any functional alterations in the cells due to the presence of colostrum the induction of tyrosine aminotransferase (EC 2.6.1.5) and glutamine synthetase (EC 6.3.1.2) by dexamethasone was studied. Although colostrum seemed to increase the basal activities of the enzymes, no significant effects on the degree of induction could be detected.”
Names both Colostrum and L-Glutamine in its title.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Colostrum, L-Glutamine, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
