HelloPharmacist Scorecard of L-Glutamine 5 g Blue Raspberry by Nutricost
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: L-glutamine, an amino acid your body naturally makes and uses for gut function, immune health, and muscle recovery. The 5-gram serving also includes inactive ingredients — malic acid, citric acid, natural flavors, sucralose, and blue spirulina — that help flavor and preserve the powder.
Does it work?
Strong evidence
The evidence we hold shows L-glutamine is effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma — meaning there's some promising research, but we need more solid data to be fully confident.
How safe is it?
Well-documented data
L-glutamine is generally well tolerated in healthy adults. Common side effects are mostly digestive — belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.
Headache and musculoskeletal pain have also been reported. If you have kidney or liver disease, use it only under medical supervision.
There isn't enough reliable safety data to recommend supplemental doses during pregnancy or breastfeeding unless your doctor or pharmacist advises otherwise.
Meds to double-check
Moderate interaction found
The main medication type to double-check before starting this product is anticonvulsants (drugs that prevent seizures). The interaction is theoretical but documented as Moderate severity.
Use the search tool on this page to confirm your specific medication, then talk it over with your own doctor or pharmacist.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
L-glutamine may be worth considering if you have sickle cell disease or are recovering from surgery or critical illness, and if the evidence for your specific situation interests you. If you take anticonvulsant medications, check with your own doctor or pharmacist first.
Otherwise, it's generally well tolerated in healthy people, though digestive upset is common at higher doses.
