What does an L-glutamine supplement do, and how much is in Reviralis?
An L-glutamine supplement supplies a common amino acid that food protein already provides. On the Reviralis Complete label, L-glutamine is second in a 661 mg blend, so it holds at most 330.5 mg per serving of two capsules. Prescription glutamine powder is dosed in grams. No source tests this product, and the real amount is not printed.

The ingredient01
What is an L-glutamine supplement?
L-glutamine is an amino acid, one of the building blocks of protein. Meat, eggs, dairy and beans already supply it, and a capsule adds a measured extra.
Product pages for glutamine often mention gut comfort and workout recovery. Those are shelf-talk claims. The sources we read are narrower: glutamine has been studied mainly in cancer care, food glutamine is safe, and a supplement calls for a provider check (MSK About Herbs, Glutamine).
The same source notes case reports of liver and kidney injury at high doses. That does not describe a capsule with a few hundred milligrams in it. It does explain why a clinician wants to know about the bottle.
The numbers02
How much L-glutamine can Reviralis hold?
At most 330.5 mg per serving, and the label does not say how close to that it gets. The ceiling comes from where the name sits in the blend.
The Supplement Facts panel prints one blend of 661 mg for 18 names. US rules list members from most to least by weight (21 CFR 101.36). L-glutamine is second. If it held more than half the blend, it would have outweighed DMAE bitartrate, which is listed first. So the most it can hold is 661 divided by 2, or 330.5 mg.
The least is not printed. The table sets the figures side by side.
| Item | Amount |
|---|---|
| Reviralis, L-glutamine (label position 2) | At most 330.5 mg, which is 0.33 g |
| Prescription L-glutamine powder | Dosed in grams, twice a day, by body weight (FDA, L-glutamine) |
| Gut or recovery claim for Reviralis | No study of the product |
A prescription dose is a different product used for a different purpose, so the comparison is about scale, not about treatment. Even at the ceiling, a serving is a fraction of a gram.
Claims03
Does glutamine help gut health or recovery?
We found no source that shows a gut or recovery benefit from the amount Reviralis can hold. The honest answer is that nobody has tested it.
The Reviralis label never names gut health, recovery or herpes. It carries the standard line that the claims have not been evaluated by the FDA and that the product is not meant to diagnose, treat, cure or prevent any disease (FDA, Structure/function claims). Supplements do not need FDA approval before sale, and the maker answers for safety and truthful labels.
Do I have a liver or kidney condition that makes an amino acid supplement a poor idea? Does a blend I cannot see the amounts of change that answer? Is food enough for me?

Who should check with a clinician first?
Anyone with a liver or kidney condition, anyone on prescription medicine and anyone pregnant or nursing. The label says as much in its caution paragraph.
- Read the full caution on the side effects page and on the bottle. It also says not for anyone under 18.
- Keep taking prescribed medicine, including any antiviral. Do not stop or change it because of a supplement.
- See a clinician for a diagnosis. Other conditions look like herpes, and we found no source showing a supplement prevents or treats outbreaks.
- Call 911 for trouble breathing, a seizure, chest pain, swelling of the face or throat, or sudden confusion with a severe headache and stiff neck.

FAQ05
Reviralis questions people ask
Is L-glutamine the same as glutamic acid?
No. They are two different amino acids with similar names, and both are on the Reviralis label. Glutamine is listed second in the blend and glutamic acid third. Their ceilings are 330.5 mg and 220.3 mg, and neither real amount is printed.
How many mg of L-glutamine are in Reviralis?
The label does not print it. Glutamine is second in a 661 mg blend, so it holds at most 330.5 mg per two-capsule serving. The floor is unknown. Only the order of the list limits it, and no lab report is published.
Does L-glutamine cause side effects?
Food glutamine is safe, but a supplement should be checked with a provider, and case reports describe liver and kidney injury at high doses. A few hundred milligrams in a capsule is far below those doses, though your own health history decides.
Can L-glutamine help with cold sores or herpes?
We found no source showing that. Herpes has no cure, and prescription antivirals are the studied care for outbreaks and daily suppression. Keep taking any prescribed antiviral and ask a clinician before adding a supplement.
