After Burn
Also known as: L-Glutamine, Glutamic acid amide, 2-Aminoadipic acid, Glutamine
Overview
Glutamine is a conditionally essential amino acid that plays a crucial role in various physiological processes, such as protein synthesis, immune function, and gut health. It is found naturally in high-protein foods such as meat, fish, dairy, and eggs. Glutamine supplementation is commonly utilized in clinical settings to support recovery from burns, promote healing of wounds, and enhance immune response. While research has shown mixed results regarding its efficacy in improving outcomes for burn patients, glutamine remains an important focus in post-burn nutritional support regimes. Its forms include powders and capsules, and it is generally well-absorbed when consumed.
Benefits
Research indicates that glutamine supplementation may lead to significant benefits in burn recovery. A systematic review revealed that it could shorten the length of hospital stays by an average of approximately 7.95 days and improve wound healing rates (WMD = 9.15) in burn patients. Additionally, glutamine may reduce the incidence of wound infections (RR = 0.38), although effects on non-wound infections and mortality were inconclusive. Most benefits are noted in burn patients, particularly during the acute phase of recovery. Overall, while the evidence is promising, further larger-scale studies are recommended for definitive conclusions.
How it works
Glutamine functions by reinforcing gut barrier integrity, modulating immune response, and supporting energy metabolism. It acts as a nitrogen donor for amino acid and nucleotide synthesis, and participates in the urea cycle. Additionally, glutamine influences several signaling pathways, aiding in protein synthesis and cell proliferation, thereby benefiting the recovery processes in individuals with burn injuries.
Side effects
Glutamine is typically regarded as safe; however, gastrointestinal disturbances such as nausea and diarrhea may occur in more than 5% of users. Uncommon side effects (1-5%) are rarely reported, while severe allergic reactions are less than 1%. Caution is suggested for individuals with severe kidney or liver conditions, and potential interactions with chemotherapy drugs should be noted. Pregnant or breastfeeding women should consult a healthcare provider prior to use due to limited data on safety in these populations.
Dosage
The minimum effective dose of glutamine generally starts at 5 grams per day, with an optimal range of 5-20 grams specifically for burn recovery. Some sources suggest a maximum safe intake of 30 grams per day, with intake ideally timed around meals to decrease gastrointestinal discomfort. Glutamine is accessible in both powder and capsule forms, and adequate hydration may enhance absorption.
FAQs
Is glutamine safe for everyone?
Glutamine is considered safe for most, but individuals with severe kidney or liver disease should consult a healthcare provider before use.
When is the best time to take glutamine?
It is recommended to take glutamine with meals to minimize potential gastrointestinal side effects.
What results can I expect from taking glutamine?
Glutamine may enhance wound healing and reduce hospital stays in burn patients, although results can vary by individual.
Can I replace my standard care with glutamine?
Glutamine should not replace standard medical care; it is best viewed as an adjunct therapy during recovery.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/38243579/ – This systematic review analyzes 22 trials involving 2170 burn patients, indicating that glutamine supplementation can effectively shorten hospital stays and improve wound healing. However, it found no significant impact on mortality or non-wound infections, highlighting the need for more extensive studies.

Some reviews indicated beneficial effects while others did not, suggesting a need for careful interpretation and further research.
- https://academic.oup.com/jbcr/article-abstract/45/3/675/7577730?login=false&redirectedFrom=fulltext – This systematic review focused on the role of glutamine in wound healing within burn patient populations. Although promising results were found for improving wound healing and reducing infection rates, the evidence was limited by the small sample sizes of studies included.
