Supplements Before Surgery: What to Tell the Surgical Team
Supplements before surgery belong on the list you give the surgical team, even ones you think are mild. Several names in the Reviralis blend, such as grape seed, bilberry and DHA, are noted for bleeding effects in sources we cite. The label gives no stop date, so the team and the anesthesia staff decide when you stop.

The list01
Why do surgeons ask about supplements?
Because some supplements change bleeding, blood pressure or how anesthesia medicine behaves, and the team cannot plan around what it does not know.
Picture the intake call: the nurse asks for prescriptions, then "anything over the counter". A bottle of capsules is easy to leave out because it feels like food. Say it anyway, with the name of the product and the dose on the label.
The Reviralis label asks you to consult a provider before use if you have a medical condition or take prescription medicine, and an operation counts as a medical event. The label gives no surgery instruction of its own.
Names to flag02
Which Reviralis names relate to bleeding or blood pressure?
Five lines stand out in the sources we cite. None was tested in Reviralis itself, and the blend prints no amount for any name.
| Name | What a source notes | Where printed |
|---|---|---|
| Vitamin E (27 mg) | High doses may raise bleeding risk, including with anticoagulants (NIH ODS, Vitamin E) | Vitamin line, amount printed |
| DHA | High omega-3 doses may prolong bleeding | Blend, no amount |
| Bilberry fruit extract | May add to blood thinners (MSK About Herbs, Bilberry Fruit) | Blend, no amount |
| Licorice root extract | Can raise blood pressure and lower potassium | Blend, no amount |
| Green tea leaf extract | Liver injury reported with extracts | Blend, no amount |
The ceilings from label order put DHA at no more than 41.31 mg and bilberry at no more than 82.62 mg, far under the amounts in the cited cautions. That does not rule out an effect for someone on other drugs, so the team still wants to know.
Stop timing03
How long before surgery should you stop supplements?
There is no single number we can give. Your surgeon or anesthesia team gives the date, and it varies with the operation and with each product.
Many hospitals send a written list a week or two ahead. Wait for that sheet, or call and ask. Do not pick a date from a blog, ours included.
- Ask: "Which of these do I stop, and on what day?"
- Ask: "When can I restart, and who tells me?"
- Ask about prescription pills too. Keep taking prescribed medicine, including any antiviral, unless the team says otherwise.
- Do not stop a prescription on your own because of a supplement question.

How do you build a list the team can use?
Write one line per item: product name, what the label calls the serving, how many you take and how often.
For Reviralis that is "Reviralis Complete, 2 capsules daily, taken before a meal". Attach a photo of the Supplement Facts panel. Then add every medicine, vitamin and herbal product in the house.

After the operation05
When is it time to call for help after surgery?
Call the surgical team for bleeding that will not stop, a fever or a wound that looks worse. Call 911 for trouble breathing, chest pain, a seizure or swelling of the face or throat.
Do not restart a supplement until the team says you may. If a clinician cannot see you soon, a pharmacist can answer the plain interaction questions.
FAQ06
Questions about supplements and surgery
Should I tell my surgeon about vitamins and herbal capsules?
Yes, every one. List the product name, the dose on the label and how often you take it. Vitamins and herbal products can affect bleeding or blood pressure, and the team cannot plan around what it is not told.
Can I take a multivitamin the morning of surgery?
Ask the surgical team. Fasting rules often forbid anything by mouth, and the team may allow only certain pills with a sip of water. Do not guess, and bring your list.
Does Reviralis thin the blood?
No source tested Reviralis for that. Some names in it, such as vitamin E, DHA and bilberry, are noted for bleeding effects in cited sources. The amounts for blend names are not printed, so tell your team and ask.
When can I restart supplements after an operation?
When the surgical team says so. They know your wound, your medicines and your recovery. Ask for a restart date at the discharge visit and write it on your list.
