Vitamin A, C, D and E Supplement Amounts in Reviralis: Vitamin E 27 mg, Vitamin C 125 mg
The Reviralis label prints four fat- and water-soluble vitamin lines per serving of 2 capsules: vitamin A 720 mcg RAE as beta carotene, vitamin C 125 mg, vitamin D 2.5 mcg and vitamin E 27 mg. Vitamin C and E sit far below their adult upper limits of 2,000 mg and 1,000 mg. No cited source ties these four to herpes outbreaks.

The four lines01
What vitamin A, C, D and E amounts does Reviralis print?
Reviralis prints vitamin A at 720 mcg RAE, vitamin C at 125 mg, vitamin D at 2.5 mcg and vitamin E at 27 mg per serving of two capsules. They are the first four of the 22 vitamin and mineral lines.
Q: Are these amounts hidden in the blend? A: No. Every vitamin line has its own amount and a percent Daily Value, so this group is the easiest part of the label to check. The label sets the serving at two capsules, though the pack and sales page say one. The site follows the label.
Name by name02
What is in each of the four vitamin lines?
Each is a nutrient the body needs in small amounts. The label amount says what a serving supplies, not what a capsule does for you.
Vitamin A (as beta carotene), 720 mcg RAE
Beta carotene is the plant form the body converts to vitamin A. The 3,000 mcg RAE upper limit applies to preformed vitamin A only, so it does not apply here. Trials that raised lung cancer risk in smokers used 20 to 30 mg of beta carotene a day (NIH ODS, Vitamin A).
Vitamin C (as ascorbic acid), 125 mg
This is about 6% of the 2,000 mg adult upper limit. Regular vitamin C did not significantly cut colds in the general population, and the source does not cover herpes (NIH ODS, Vitamin C).
Vitamin D (as cholecalciferol), 2.5 mcg
This is 13% of the Daily Value. We cite no source on vitamin D and herpes or on a vitamin D limit, so we state only the label percentage.
Vitamin E (as DL-alpha tocopheryl acetate), 27 mg
At 180% of the Daily Value it sounds large, yet it is under 3% of the 1,000 mg supplement limit. High doses can raise bleeding risk, most of all with warfarin (NIH ODS, Vitamin E).
See the numbers03
How big is 180% of the Daily Value, really?
A percent over 100 compares a serving with the daily need, not with the safe ceiling. Tap a ring, then switch to the upper-limit view.
Per serving (2 capsules). The Daily Value is the label reference amount; the upper limit is the most NIH says is safe for nearly all healthy adults from supplements (NIH ODS, Zinc) (NIH ODS, Vitamin C) (NASEM 2019, DRI Tolerable Upper Intake Levels for Elements) (NIH ODS, Vitamin B6) (NIH ODS, Folate) (NIH ODS, Vitamin E) (NIH ODS, Niacin) (NIH ODS, Magnesium). A vitamin line above 100% of the Daily Value is not a warning by itself; the upper limit is the line to watch. Rings are drawn from the label, not from a lab test.
The evidence04
Do vitamins A, C, D and E help with herpes outbreaks?
No cited source shows that these four vitamins prevent or reduce herpes outbreaks. They are nutrients, and the label states no purpose for them.
Herpes has no cure, and the CDC describes prescription antivirals as the proven care (CDC, About Genital Herpes). The sales page quotes "Reinforces your body's natural defenses". The nearest vitamin evidence we hold is the vitamin C finding on colds (NIH ODS, Vitamin C). No study tested Reviralis.

Who should ask first06
Who should check with a clinician first?
Ask first if you take warfarin, smoke, or already take a multivitamin. The label also warns about medicines, medical conditions, pregnancy and nursing.
- Vitamin E in high doses can raise bleeding risk with warfarin (NIH ODS, Vitamin E).
- Smokers are told to avoid high-dose beta carotene (NIH ODS, Vitamin A).
- Under 18: the label says not to use it.

FAQ08
Questions about vitamins A, C, D and E in Reviralis
How much vitamin C is in Reviralis?
Reviralis prints 125 mg of vitamin C per serving of two capsules, which is 139% of the Daily Value. The adult upper limit is 2,000 mg a day, so the label amount is about 6% of that limit.
How much vitamin E is in Reviralis?
The label prints 27 mg of vitamin E as DL-alpha tocopheryl acetate, 180% of the Daily Value. The adult upper limit from supplements is 1,000 mg, so this is under 3% of it.
Is the vitamin A in Reviralis retinol?
No. The label says vitamin A comes as beta carotene, 720 mcg RAE. The 3,000 mcg RAE upper limit applies to preformed vitamin A, not to beta carotene, though smokers are told to avoid high-dose beta carotene.
Does Reviralis have enough vitamin D?
It prints 2.5 mcg of vitamin D, 13% of the Daily Value. That is a small share of the daily need. Ask a clinician about vitamin D testing or a separate supplement.
Can vitamin C stop a herpes outbreak?
No cited source shows that. Regular vitamin C did not significantly cut colds in the general population, and that source does not cover herpes. Prescribed antivirals are the proven care.
Should smokers take Reviralis?
Smokers should ask a clinician first. Trials that raised lung cancer risk used 20 to 30 mg of beta carotene a day, and smokers are told to avoid high-dose beta carotene supplements.
