What is a typical inositol supplement dosage, and what does Reviralis hold?
Inositol supplement dosage in studies runs in grams a day, with about 2,000 mg twice a day used in some trials. On the Reviralis Complete label, inositol is 6th of 18 names in a 661 mg blend, so it holds at most 110.2 mg per serving of two capsules. That is about one eighteenth of a study dose.

The ingredient01
What is inositol and how is it dosed in studies?
Inositol is a sugar-like compound the body makes and food supplies. Studies of it use grams a day, and large doses cause stomach upset (Carlomagno 2011, Inositol Safety (Eur Rev Med Pharmacol Sci)).
A common study figure is about 2,000 mg, taken twice a day. That is 4 grams in a day, in a form the trial makers chose and measured. The trials also pick a condition and a group of people, which a general supplement label does not do.
So when a bottle says inositol, the next question is how many milligrams. On the Reviralis label the answer is not printed. The Supplement Facts panel names inositol inside a blend and stops there.
The arithmetic02
How much inositol can two Reviralis capsules hold?
At most 110.2 mg. That is the ceiling set by inositol's spot as name number 6 in the 661 mg blend.
US rules list blend members from most to least by weight, and the blend total is the weight of all of them together (21 CFR 101.36). Six names share the top of the list. The sixth cannot outweigh the five before it, so it cannot exceed 661 divided by 6. That is 110.17 mg.
Now set it against the study dose. Two grams is 2,000 mg. Divide 2,000 by 110.2 and you get about 18. A single study dose is about 18 times the label ceiling, and the study dose is taken twice a day.
| Measure | Amount |
|---|---|
| Studies, per dose | About 2,000 mg, taken twice a day |
| Studies, per day | About 4,000 mg |
| Reviralis, most per serving | 110.2 mg |
| Gap, one study dose vs ceiling | About 18 times |
| Printed amount on the label | Not printed |
The ceiling is arithmetic about the list order, not a lab result. The real figure could be lower.
What it means03
Does a tiny inositol amount mean it is useless or risky?
Neither can be claimed. A small amount is unlikely to cause the stomach upset seen with grams, and it is also far below the amounts anyone has studied.
That leaves a plain conclusion. The trial doses cannot be borrowed to describe Reviralis. No source we read tests inositol for herpes, and the product has no trial of its own.
Herpes simplex virus has no cure. Prescription antivirals such as acyclovir, valacyclovir and famciclovir are the proven care for outbreaks and for daily suppression, and a clinician chooses between them (CDC, STI Treatment Guidelines: Herpes). A Cochrane review of cold-sore prevention found no evidence that lysine or one other supplement worked (Chi 2015, Cochrane: Preventing Cold Sores).

What should you check before taking an inositol blend?
Start with your medicine list and your health history, because the label asks for both.
- The label says consult your provider if you are pregnant or nursing, have a medical condition or seizure history, or take prescription medicine. Not for anyone under 18.
- Keep taking prescribed medicine, including any antiviral. Do not stop or swap it.
- See a clinician for a diagnosis, because other conditions look like herpes.
- 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.
Is a milligram figure available for each name in the blend? Does inositol matter with my medicines? Would food or a doctor-advised product serve me better?

FAQ05
Reviralis questions people ask
How many mg of inositol are in Reviralis?
The label does not print it. Inositol is 6th of 18 names in a 661 mg blend, so it holds at most 110.2 mg per two-capsule serving. It could hold less, and no lab report is published to say.
What inositol dose do studies use?
Studies use grams a day. One common figure is about 2,000 mg taken twice a day. Large doses cause stomach upset. Those trials chose a specific group of people and condition, so they do not map onto a general supplement label.
Can inositol cause side effects?
At large doses it can upset the stomach, according to the source we read. Reviralis can hold at most 110.2 mg per serving, far below study amounts. Your own health history still decides, so ask a pharmacist about the whole blend.
Is inositol a vitamin?
No. Inositol is a sugar-like compound that the body makes and food supplies. It is sometimes grouped with B vitamins in older writing, but it has no recommended daily amount in the sources we use. The Reviralis label lists it in the blend.
