Vitamin B6 706 Percent Daily Value in Reviralis: Is 12 mg Too Much?
Vitamin B6 at 706 percent of the Daily Value is 12 mg per two capsules in Reviralis. That is about an eighth of the 100 mg upper limit, so the percent looks bigger than the risk. The label also prints folic acid 400 mcg, biotin 3 mcg and choline 31 mg. No source ties any of them to herpes outbreaks.

| Name on the label | Niacin (as Niacin) 12.5 mg, 78% DV |
|---|---|
| What it is | A B vitamin; the label gives the form only as 'niacin' |

| Main caution | Nicotinic acid tends to flush the skin at 30 to 50 mg or more. 12.5 mg is under that, but the label does not say which form it is. Adding a multivitamin raises the total. |
| Name on the label | Vitamin B6 (as Pyridoxal Phosphate) 12 mg, 706% DV |
|---|---|
| What it is | A B vitamin, as pyridoxal phosphate |
| Place on the label | Its own line, amount printed |

|---|---|
| What it is | A B vitamin, as folic acid |
| Place on the label | Its own line, amount printed |

|---|---|
| What it is | A B vitamin |
| Place on the label | Its own line, amount printed |

| Daily need or amount used in research | Adults need 30 mcg a day; no upper limit is set |
| Upper limit for adults | No upper limit set |
| Strength of evidence | Essential nutrient; 3 mcg is a tenth of the daily need |
| Main caution | Large biotin doses can distort some lab tests, including thyroid and troponin tests. Three mcg is far too small to do that, but tell the lab about any biotin product. |

| Place on the label | Its own line, amount printed |

Vitamin B602
Is vitamin B6 at 706 percent of the Daily Value too much?
No. Vitamin B6 12 mg is a big percent of a small need, and it is about 12% of the 100 mg upper limit.
The Daily Value for B6 is only 1.7 mg, so 12 mg divided by 1.7 gives 706%. Long-term intakes of 100 mg or more can damage sensory nerves (NIH ODS, Vitamin B6). Twelve mg is far below that, but the gap shrinks fast if you also take a B-complex or an energy product. Add every B6 number from other products before you decide.
Folate and biotin03
What do folic acid 400 mcg and biotin 3 mcg mean?
Folate is printed as 680 mcg DFE, which is 400 mcg of folic acid, and biotin is a tiny 3 mcg.
400 mcg of folic acid times 1.7 gives 680 mcg DFE. The 1,000 mcg limit applies to folic acid, so the label sits at 40% of it. Folic acid can hide the anemia of low B12, and it may weaken phenytoin (NIH ODS, Folate). Large biotin doses can distort lab tests (NIH ODS, Biotin).
Keep taking every prescribed medicine, including any antiviral, unless your prescriber says otherwise. 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 severe headache and stiff neck.

FAQ06
Questions about vitamin B6, folate and choline in Reviralis
Why is vitamin B6 706 percent of the Daily Value?
The B6 Daily Value is only 1.7 mg. Reviralis prints 12 mg, and 12 divided by 1.7 is 706%. The upper limit is 100 mg, so 12 mg is about 12% of it.
Can vitamin B6 12 mg cause nerve damage?
Not at that amount. Nerve damage has been reported with long-term intakes of 100 mg or more. Add the B6 from other products.
What is DFE on the folate line?
DFE means dietary folate equivalents. Folic acid counts 1.7 times, so 400 mcg of folic acid is printed as 680 mcg DFE.
Does biotin 3 mcg affect lab tests?
Unlikely at 3 mcg. High-dose biotin can distort thyroid and troponin tests, so tell the lab about any biotin product.
Is 31 mg of choline much?
No. Adults need 425 to 550 mg a day, so 31 mg is about 6%. The upper limit is 3,500 mg, and the label amount is far below it.
Do B vitamins help herpes outbreaks?
No source we found shows that. NIH's complementary health center has not found a supplement that prevents or treats herpes outbreaks, and antivirals are the proven care.
