What does a phosphatidylserine supplement need to match the trials?
A phosphatidylserine supplement is usually taken at 100 to 200 mg a day, and it is not FDA-approved for any condition. On the Reviralis Complete label it is the last of 18 names in a 661 mg blend, so it holds at most 36.7 mg per serving of two capsules. That is under 37% of the low end of the usual range.

The ingredient01
What is the usual phosphatidylserine dose?
Cleveland Clinic says an adult could take about 100 to 200 mg of phosphatidylserine a day, and that it is not FDA-approved to treat any medical condition (Cleveland Clinic, Phosphatidylserine). That is a long way from proof.
Phosphatidylserine is a fat-like compound found in cell membranes. Supplements use it in the hope of helping memory.
Notice the scale: the usual range is measured in hundreds of milligrams a day.
The arithmetic02
How much phosphatidylserine can Reviralis hold?
At most 36.7 mg per serving of two capsules. Phosphatidylserine is the last name in the blend, and the last name can never outweigh the average.
US rules list blend members from most to least by weight (21 CFR 101.36). Eighteen names share 661 mg. If every name weighed the same, each would be 36.7 mg. The last name is the lightest, so it cannot be more than that average. It may be far less.
| Measure | Amount per day |
|---|---|
| Typical supplement range | 100 to 200 mg |
| Reviralis, most per serving | 36.7 mg |
| 200 mg divided by the ceiling | About 5.4 times more |
| Printed amount on the label | Not printed |
Even the low end of the typical range, 100 mg, is about 2.7 times the ceiling. Bottle size does not change that: a bottle holds 30 servings, and the label says two capsules a day.
What it means03
Can a last-place amount match any trial result?
No trial result can be assumed for Reviralis. Trials report on the dose and product they tested, and this product was not tested at all.
The same holds for the sales page. It talks about outbreaks and flare-ups, while the label never mentions herpes. We found no source linking phosphatidylserine to herpes. Herpes simplex virus has no cure, and prescription antivirals are the proven care for outbreaks and daily suppression, decided with a clinician (CDC, STI Treatment Guidelines: Herpes).
The source on phosphatidylserine also notes possible stomach upset and trouble sleeping, and that it may weaken anticholinergic drugs. Pregnancy safety is not established (Cleveland Clinic, Phosphatidylserine). At a few dozen milligrams those points are not guaranteed to apply, but a pharmacist should hear about them.

What should you ask before taking it?
Ask what each name weighs, and ask whether your own medicines clash with any of the 18.
Do I take any anticholinergic medicine, such as some bladder or allergy drugs? Does phosphatidylserine matter during pregnancy? Can you look up the whole blend for me, name by name?
- Follow the label caution: ask first if pregnant or nursing, if you have a medical condition or seizure history, or if you take prescription medicine. Not for anyone under 18.
- Keep taking prescribed medicine, including any antiviral.
- 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
How much phosphatidylserine is in Reviralis?
The label does not print it. Phosphatidylserine is the 18th name in a 661 mg blend, so it holds at most 36.7 mg per two-capsule serving. The true amount could be lower, and no lab report is published.
What is the usual phosphatidylserine dose?
The source we read calls 100 to 200 mg a day typical. That is well above the 36.7 mg ceiling that the last position in the Reviralis blend allows.
Has phosphatidylserine been approved by the FDA?
Not for any condition, according to Cleveland Clinic. Supplements are not approved before sale, and the label carries the standard disclaimer.
Does phosphatidylserine affect other medicines?
The source says it may weaken anticholinergic drugs. Pregnancy safety is not established. Show your pharmacist the whole label and your medicine list so each name in the blend gets checked against what you take.
