Can You Take Brain Supplements With Blood Thinners?

Quick answer

Brain supplements and blood thinners can interact, so ask your prescriber or pharmacist before combining them. Coenzyme Q10 may weaken warfarin, and ginkgo may raise bleeding risk. Keep taking your blood thinner exactly as prescribed, and never change a dose because of a supplement.

Which brain supplement ingredients affect blood thinners?

A few brain supplement ingredients can change how a blood thinner behaves, and the table shows what our sources say. Keep taking your blood thinner as prescribed.

Ingredients and blood thinners
IngredientWhat our source says
Coenzyme Q10 (in Synaptril)May weaken warfarin (Linus Pauling Institute, Coenzyme Q10)
Ginkgo (not in Synaptril)May raise bleeding risk with warfarin-type drugs (NCCIH, Ginkgo)
Turmeric extract (in Synaptril)No drug interactions named; ask your pharmacist (NCCIH, Turmeric)
Fish oil, vitamin ENot covered by our sources; ask

Which Synaptril ingredient matters most with blood thinners?

Coenzyme Q10 matters most, because it has been reported to reduce warfarin's effect, and people on warfarin should have their INR checked (Linus Pauling Institute, Coenzyme Q10).

The label lists CoQ10 last in the blend, so by our blend math a capsule holds at most about 35 mg. That is small, but small is not none. The label itself says to consult a physician if you take a medication. It does not name warfarin, so the label alone cannot clear you.

FAQ01

Synaptril questions people ask

Does ginkgo raise bleeding risk with warfarin?

It may. NCCIH says ginkgo may increase bleeding risk with anticoagulants such as warfarin. Ginkgo is not in Synaptril, but it appears in many other memory products.

Who checks warfarin levels after a new supplement?

Your prescriber does. Linus Pauling Institute advises people on warfarin to consult their prescriber about CoQ10 and have INR checked.

Should I tell my surgeon about brain supplements?

Yes. NCCIH notes supplements can be risky before surgery, so list every product you take, with doses, at your pre-surgery visit.
