HelloPharmacist Scorecard of GI Protect Natural Cherry Flavor Sugar- and Stevia-Free by XYMOGEN
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
GI Protect contains 2 active ingredients: L-glutamine and immunoglobulin G. L-glutamine is an amino acid your body makes and uses for gut lining support and immune function.
Immunoglobulin G is an antibody naturally present in colostrum (early breast milk), and colostral whey peptides are protein fragments from the same source. The powder also contains inactive ingredients like cherry flavor, beet powder, citric acid, malic acid, monk fruit extract, silica, and sunflower lecithin for taste and texture.
Does it work?
Moderate evidence
L-glutamine is rated effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma.
We don't have effectiveness ratings on file for immunoglobulin G or colostral whey peptides in this product.
How safe is it?
Well-documented data
L-glutamine is rated likely safe during pregnancy and lactation. In healthy adults, it's generally well tolerated, but people with kidney or liver disease should use it only under medical supervision.
The most common side effects from oral glutamine are belching, bloating, constipation, diarrhea, flatulence, gastrointestinal pain, headache, nausea, and vomiting — especially at higher doses (10–30 grams daily). A small number of people have reported dizziness, and in rare cases, people with bipolar disorder taking glutamine have experienced mania or hypomania.
If you have liver or kidney disease, neurological conditions, or bipolar disorder, talk with your pharmacist or doctor before starting.
Meds to double-check
Moderate interaction found
Check your anticonvulsant medications (seizure drugs) before taking this product — glutamine theoretically could reduce their effectiveness, though this hasn't been reported in patients. We have no documented interactions for immunoglobulin G or colostral whey peptides.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
GI Protect may help with gut support and recovery, particularly if you have sickle cell disease or are recovering from surgery or critical illness. If you take anticonvulsant medications, check them against the interaction tool on this page first.
Anyone with kidney, liver, or bipolar disorder should talk with their pharmacist before using it.

GI Protect Natural Cherry Flavor Sugar- and Stevia-Free by XYMOGEN Drug Interactions
HelloPharmacist Interaction Report
GI Protect by XYMOGEN contains L-glutamine, which has documented interactions with medications.
The most serious concern is with anticonvulsant drugs (used to prevent seizures): glutamine is broken down into an excitatory brain chemical called glutamate, which theoretically could work against how these medications suppress seizure activity. However, this interaction hasn't been reported in actual patients yet — it's a theoretical risk based on how glutamine is metabolized.
Read the full breakdown — every affected drug type, severity by severity
Altogether, these interactions span 50 individual medications. We were unable to check immunoglobulin G and colostral whey peptides — we hold no interaction data for those ingredients — so there may be additional interactions we cannot document here.
If you take any anticonvulsant medication, run it through the checker below before starting this product. That's the one drug category with documented concern.

For each ingredient in GI Protect Natural Cherry Flavor Sugar- and Stevia-Free with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Colostral Whey Peptides
Levodopa
Theoretically, whey protein might decrease levodopa absorption.
Small clinical studies show that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease.
Bisphosphonates
Theoretically, whey protein might reduce the absorption of bisphosphonates.
Whey protein contains minerals such as calcium that bind bisphosphonates in the gut. Advise patients to take bisphosphonates at least 30 minutes before whey protein, but preferably at a different time of day.
Quinolone Antibiotics
Theoretically, whey protein might decrease quinolone absorption.
Whey protein contains minerals, such as calcium, that can bind to quinolones in the gut. To avoid this interaction, advise patients to take oral quinolones at least 2 hours before or 4-6 hours after whey protein.
Tetracycline Antibiotics
Theoretically, whey protein might decrease tetracycline absorption.
Whey protein contains minerals, such as calcium, that bind to tetracyclines in the gut. To avoid this interaction, advise patients to take oral tetracyclines at least 2 hours before or 4-6 hours after whey protein.
L-Glutamine
Anticonvulsants
Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.
