Vitamin B6 706 Percent Daily Value in Reviralis: B Complex Amounts and Choline 31 mg
Vitamin B6 at 706% of the Daily Value sounds extreme, but the Reviralis label prints 12 mg, about an eighth of the 100 mg adult upper limit. The same group holds thiamine, riboflavin, niacin, folate, biotin, pantothenic acid and choline 31 mg, eight printed lines per serving of two capsules.

The eight lines01
Why does Reviralis show vitamin B6 at 706% of the Daily Value?
The 706% figure comes from a small daily need. The Daily Value for B6 is only 1.7 mg, and the label prints 12 mg, which is about 12% of the 100 mg adult upper limit (NIH ODS, Vitamin B6).
Q: Is a high percent a warning? A: Not by itself. Thiamine (250%) and pantothenic acid (240%) also print large percents because their daily needs are tiny.
Name by name02
What is in each B vitamin line and the choline line?
Seven B lines and choline each have a printed amount. Most have no set upper limit.
Thiamine (B1), 3 mg
This is 250% of the Daily Value, with no upper limit set.
Riboflavin (B2), 1.7 mg
This is 131% of the Daily Value. It can turn urine bright yellow, which is harmless.
Niacin (B3), 12.5 mg
The adult limit from supplements is 35 mg, so the label is about 36% of it. The label does not name the form (NIH ODS, Niacin).
Vitamin B6 (pyridoxal phosphate), 12 mg
Nerve damage was reported at very high long-term doses, and B6 can lower phenytoin levels (NIH ODS, Vitamin B6).
Folate, 680 mcg DFE (400 mcg folic acid)
The extra DFE is arithmetic, not a second ingredient. Folic acid can hide a vitamin B12 deficiency (NIH ODS, Folate).
Biotin, 3 mcg
At 10% of the Daily Value it is small. NIH ties lab-test problems to high doses (NIH ODS, Biotin).
Pantothenic acid (B5), 12 mg
This is 240% of the Daily Value, with no upper limit set.
Choline (bitartrate), 31 mg
This is 6% of the Daily Value. We found no source for this line, so we state only the label percentage.
The evidence03
Do B vitamins help with herpes outbreaks?
No cited source says they do. They are nutrients the body needs for energy, and the label states no purpose.
The sales page quotes "Supports a calm stress response". No cited trial tested a vitamin for that, and stress is linked to recurrence only weakly (Chida and Mao 2009, Stress and HSV Recurrence (Brain Behav Immun)). Keep any antiviral you are prescribed (CDC, About Genital Herpes).

FAQ06
Questions about B vitamins and choline in Reviralis
Is 706% of the Daily Value of vitamin B6 safe?
The percent is large because the Daily Value is only 1.7 mg. The label prints 12 mg, about 12% of the 100 mg adult upper limit.
How much folic acid is in Reviralis?
The label prints 400 mcg of folic acid, shown as 680 mcg DFE. The adult upper limit is 1,000 mcg of folic acid, so the label is 40% of it. Folic acid can hide a vitamin B12 deficiency.
How much niacin does Reviralis contain?
It prints 12.5 mg of niacin without naming the form. The adult upper limit from supplements is 35 mg, so the label is about 36% of it.
How much choline is in Reviralis?
The label prints 31 mg of choline as choline bitartrate, 6% of the Daily Value. We cite no limit or research for it.
Does biotin in Reviralis affect lab tests?
At 3 mcg it is a small amount. NIH describes distorted thyroid and heart test results with high biotin doses, not this one. Still tell a lab or clinician about every supplement.
Do B vitamins calm stress?
No cited trial shows that. The sales page quotes a calm stress response, and stress is linked to herpes recurrence only weakly across 11 studies. B vitamins are nutrients the body needs.
