Memory Supplements and Blood Thinners: Ginkgo, Bleeding Risk and What to Ask
Ask your doctor or pharmacist before you combine them. Ginkgo, one of the ten Neuro Recall blend ingredients, may raise bleeding risk with warfarin (NCCIH, Ginkgo). Berberine, chromium, lipoic acid and green tea extract bring their own medicine cautions. Bring the bottle and your medicine list, and tell your surgeon or dentist about every supplement before any procedure.

Short answer
Can you take ginkgo biloba with blood thinners?
Only after your prescriber says yes. Ginkgo may raise the risk of bleeding when taken with warfarin, according to the National Center for Complementary and Integrative Health (NCCIH, Ginkgo).
Ginkgo is the second ingredient in the Neuro Recall 635 mg blend, and the label gives no amount. You cannot judge the risk by the dose, but a pharmacist can judge it against your full medicine list.
Keep taking your prescribed medicine. Never stop or change a dose on your own to make room for a supplement. Ask first, then decide.
Ginkgo
Is ginkgo biloba a natural blood thinner?
No, and it should never be used as one. The concern runs the other way: ginkgo may add to the effect of a real blood thinner and tip the balance toward bleeding (NCCIH, Ginkgo).
Our source names warfarin. Other drugs also slow clotting, such as apixaban, rivaroxaban, clopidogrel and daily aspirin. The ginkgo source does not test each one, so the safe move is to ask about whichever you take.
| Medicine type | Named in the source? | What to do |
|---|---|---|
| Warfarin | Yes: ginkgo may raise bleeding risk | Ask your prescriber before any ginkgo product |
| Newer anticoagulants (apixaban, rivaroxaban, dabigatran) | Not named | Ask; the same bleeding question applies |
| Antiplatelet drugs (clopidogrel, daily aspirin) | Not named | Ask; bring the bottle to the pharmacy |
| Planned surgery or dental work | Not named | Tell the surgeon or dentist about every supplement |

The whole formula
Which other Neuro Recall ingredients interact with medicines?
Several do. Ginkgo gets the attention, but four more blend and label ingredients have documented medicine cautions.
| Ingredient | Medicines involved | What can happen | Source |
|---|---|---|---|
| Berberine | Cyclosporine, tacrolimus; drugs cleared by CYP2D6, 2C9 or 3A4 | Raises cyclosporine and tacrolimus levels; can change how many other drugs work | (MSKCC, Berberine) |
| Chromium (120 mcg) | Insulin, metformin, other diabetes medicines; levothyroxine | Blood sugar may drop too low; thyroid pill may absorb less | (NIH ODS, Chromium) |
| Alpha-lipoic acid | Insulin, diabetes pills | Blood sugar may drop too low | (Linus Pauling Institute, Lipoic acid) |
| Green tea extract | Nadolol, atorvastatin, raloxifene | Lowers nadolol levels; interacts with the other two; contains caffeine | (NCCIH, Green tea) |
Only chromium has a printed amount, 120 mcg. The other three sit in the blend with no amounts, so a pharmacist works from the names alone.
Surgery
Should you stop memory supplements before surgery?
Ask your surgeon, and follow the date they give you. Because ginkgo may raise bleeding risk (NCCIH, Ginkgo), surgical teams usually want to know about it well ahead of time.
Our sources give no fixed number of days. That choice belongs to the person doing the procedure, and it applies to dental work and small procedures too.
List Neuro Recall on every pre-surgery form, by name. Writing "a vitamin" hides the ginkgo and the berberine.

How do you talk to a pharmacist about supplement interactions?
Bring the bottle, not a description of it. Checking interactions is a routine part of a pharmacist's job.
Show the label
Hand over the bottle or a clear photo of the Supplement Facts panel. Point out the 635 mg blend and its ten names.
Name every medicine
Include prescriptions, over-the-counter pain relievers, aspirin, sleep aids and other supplements.
Ask three questions
Does anything here raise bleeding risk with my medicine? Could anything push my blood sugar too low? Should anything be taken at a different time of day?
Write down the answer
Note the date and what was said. Share it with your prescriber at the next visit.
The side effects and interactions page lists every caution in one place.

Where do these interaction warnings come from?
Each caution links to a public health source. Read them yourself, then talk them over with your pharmacist.
- Ginkgo. National Center for Complementary and Integrative Health, 2026.Three large studies: ginkgo did not reduce dementia risk (GEM: 3,000+ adults 75+, about 6 years). Maybe a modest effect on dementia symptoms. Side effects: dizziness, stomach upset, headache. Bleeding risk with warfarin. May be unsafe in pregnancy.
- Green Tea. National Center for Complementary and Integrative Health, 2026.Uncommon liver injury reported with extract tablets or capsules; nausea, constipation, raised blood pressure; contains caffeine; reduces nadolol levels.
- Berberine. Memorial Sloan Kettering Cancer Center, About Herbs, 2026.Limited, low-quality human evidence for blood sugar and cholesterol; upset stomach, diarrhea, constipation; raises cyclosporine and tacrolimus levels; reduces CYP2D6, 2C9 and 3A4 activity; avoid in pregnancy and breastfeeding.
- Lipoic Acid. Linus Pauling Institute, Oregon State University, 2026.Evidence for cognitive decline too limited (small, mostly uncontrolled trials at 600 mg a day); may cause low blood sugar with insulin or diabetes drugs; child poisonings reported.
- Chromium: Fact Sheet for Consumers. NIH Office of Dietary Supplements, 2026.Adults 20-35 mcg a day; diabetes results mixed; with insulin or diabetes medicines may cause low blood sugar; may reduce levothyroxine absorption.
FAQ
Memory supplements and blood thinners: common questions
Does ginkgo biloba interact with warfarin?
It may. NCCIH says ginkgo may raise the risk of bleeding when combined with warfarin (NCCIH, Ginkgo). Talk to the doctor who manages your warfarin before starting any product with ginkgo, Neuro Recall included.
Can I take Neuro Recall with apixaban or clopidogrel?
Ask your prescriber first. Our ginkgo source names warfarin, not apixaban or clopidogrel, but all of them affect clotting, and ginkgo raises a bleeding question. Neuro Recall does not print its ginkgo amount, so bring the bottle to the appointment.
Can I take a memory supplement with daily aspirin?
Check with a pharmacist first. Aspirin slows clotting, and ginkgo may add to bleeding risk. If your doctor prescribed aspirin for your heart, keep taking it as directed and let them decide about the supplement.
How long before surgery should I stop ginkgo?
Ask your surgeon. Our sources give no fixed number of days, and the answer depends on the procedure and your other medicines. Tell the surgical team about Neuro Recall by name at your first visit.
Can Neuro Recall lower blood sugar too much?
It could if you also use insulin or diabetes medicines. Chromium and alpha-lipoic acid may push blood sugar too low with those drugs (NIH ODS, Chromium) (Linus Pauling Institute, Lipoic acid). Check your readings more often and ask your doctor before starting.
Does berberine interact with other medicines?
Yes. Berberine raises cyclosporine and tacrolimus levels, and it slows liver enzymes that clear many common drugs (MSKCC, Berberine). Anyone on transplant medicine, or several prescriptions, should ask a pharmacist before taking Neuro Recall.
