Three blend names, plus the last

Vanadyl Sulfate Supplement, Boron Citrate, DHA and Phosphatidylserine in Reviralis

Quick answer

Vanadyl sulfate is a vanadium salt, and in Reviralis it can hold at most 38.9 mg of the 661 mg blend. Boron citrate is at most 44.1 mg and DHA at most 41.4 mg. The label gives the compound, not the element, so neither can be checked against the elemental upper limits of 1.8 mg vanadium and 20 mg boron.

The three names01

How much vanadyl sulfate is in Reviralis?

At most 38.9 mg of the compound per serving of two capsules, and likely less. The label prints only the 661 mg blend total for 18 names, listed from most to least by weight (21 CFR 101.36, Supplement Facts Panel).

Q: Why can the amount not be read from the label? A: Only the total is printed. Vanadyl sulfate is seventeenth, so 661 divided by 17 sets its ceiling. Boron citrate is fifteenth (at most 44.1 mg) and DHA sixteenth (at most 41.4 mg).

Name by name02

What do studies say about boron, DHA and vanadyl sulfate?

Little, and none of it tests this product.

Boron (citrate)

The adult upper limit is 20 mg a day of elemental boron. The label gives boron citrate, so the compound weight cannot be set against that limit. Benefit evidence is limited, such as a 2-week knee-discomfort trial (NIH ODS, Boron) (NASEM 2019, DRI Tolerable Upper Intake Levels for Elements).

DHA

FDA considers up to 5 g a day of EPA plus DHA safe, and the label-claim limit is 2 g. The ceiling of 41.4 mg is about 2% of 2 g. Bleeding concern is mainly at high doses (NIH ODS, Omega-3 Fatty Acids).

Vanadyl sulfate

The upper limit is 1.8 mg a day of elemental vanadium, set from animal data. No function in humans is established, and we cite no source that vanadium helps blood sugar (NASEM 2001, DRIs for Boron, Vanadium and Other Trace Elements (Ch. 13)) (NASEM 2019, DRI Tolerable Upper Intake Levels for Elements).

The last name03

What is the phosphatidylserine supplement in Reviralis?

Phosphatidylserine (sunflower seed) is the eighteenth and last blend name, so it can hold at most 36.8 mg per serving.

Typical use is 100 to 200 mg a day, so the ceiling is about 37% of the low end. It is not approved by FDA for any condition. Stomach upset and insomnia are possible, and it may weaken anticholinergic drugs (Cleveland Clinic, Phosphatidylserine). Its full entry is on the bacopa and brain-support page.

Ceiling vs study04

How do the label ceilings compare with studied amounts?

Far below for DHA, and below for phosphatidylserine and bacopa. Boron and vanadyl sulfate have no such bar, because their limits are in elements.

  • Bacopa

    At most 44% of the low study amount
    Most Reviralis can hold (label order)132.2 mg
    Bacopa monnieri extract300-300 mg

    The label prints no amount for this name; 132.2 mg is the ceiling its place in the list allows. (Calabrese 2008, Bacopa in Older Adults (J Altern Complement Med))

  • Phosphatidylserine

    At most 37% of the low study amount
    Most Reviralis can hold (label order)36.8 mg
    Phosphatidylserine100-200 mg

    The label prints no amount for this name; 36.8 mg is the ceiling its place in the list allows. (Cleveland Clinic, Phosphatidylserine)

  • DHA

    At most 2% of the low study amount
    Most Reviralis can hold (label order)41.4 mg
    DHA2,000-2,000 mg

    The label prints no amount for this name; 41.4 mg is the ceiling its place in the list allows. (NIH ODS, Omega-3 Fatty Acids)

  • Inositol

    At most 1% of the low study amount
    Most Reviralis can hold (label order)110.2 mg
    Inositol12,000-12,000 mg

    The label prints no amount for this name; 110.2 mg is the ceiling its place in the list allows. (Carlomagno 2011, Inositol Safety (Eur Rev Med Pharmacol Sci))

Teal bars: the most one serving (2 capsules) can hold of that name, worked out from the label order (the real amount is not printed). Coral bars: the daily amount used in the study we found. A studied dose says what was tested, not what works for you, and no study tested Reviralis.

The evidence05

Do boron, DHA or vanadyl sulfate help with herpes outbreaks?

No cited source says so. The sales page quotes "Addresses the internal signal before it becomes visible", and none of these three names has a study behind it.

Herpes has no cure, and prescribed antivirals are the proven care (CDC, About Genital Herpes) (CDC, STI Treatment Guidelines: Herpes). Do not pause yours because you started a capsule. Report side effects to FDA MedWatch (FDA, MedWatch).

FAQ08

Questions about DHA, boron and vanadyl sulfate in Reviralis

Is vanadyl sulfate in Reviralis above the safe limit?

The label cannot show it. The 1.8 mg limit is for elemental vanadium, and the label allows up to 38.9 mg of the compound. We do not state that it exceeds or stays under the limit.

What does vanadyl sulfate do?

No function in humans is established. The upper limit comes from animal data. We cite no source showing vanadium helps blood sugar, so we make no such claim.

How much boron is in Reviralis?

At most 44.1 mg of boron citrate per serving, since it is fifteenth in the blend. The elemental share is not printed, so it cannot be compared with the 20 mg limit.

How much DHA is in Reviralis?

At most 41.4 mg per serving, about 2% of the 2 g label-claim limit for EPA plus DHA. The label prints no single amount, so the real figure may be lower.

Does DHA thin the blood?

Bleeding concern is mainly at high doses. The DHA ceiling is small, but vitamin E and bilberry in the same capsule also matter. Ask a clinician if you take warfarin.

How much phosphatidylserine is in Reviralis?

At most 36.8 mg, since it is last in the blend. Typical use is 100 to 200 mg a day, and it is not approved by FDA for any condition.
