Can You Take Turmeric With Blood Thinners?
Turmeric and blood thinners is a question for your pharmacist before you start. The evidence we hold does not establish a warfarin interaction with turmeric, but NCCIH warns that herbs and medicines can interact. Anyone on a blood thinner should ask before using any curcumin product.

Is it safe to take turmeric and blood thinners together?
Nobody can promise it is safe, and nobody can promise it is not. The evidence we hold does not establish a warfarin interaction with turmeric.
NCCIH names no specific drug interaction for turmeric, yet it warns that herbs and medicines can interact (NCCIH, Turmeric). A blank is not a green light.
Turmeric has other safety notes too. Rare liver injury has been reported, mostly with high-absorption forms, and turmeric may be unsafe in pregnancy (NCCIH, Turmeric) (NIH LiverTox, Turmeric). A blood thinner is one more reason to ask first.
Which Synaptril ingredient is flagged for blood thinners?
Coenzyme Q10 is the flagged one, not the turmeric. Both turmeric extract and CoQ10 sit in the Synaptril blend.
By the blend math, CoQ10 is at most about 35 mg a capsule and turmeric at most about 44 mg. A small amount is not a cleared amount, because the report names the ingredient, not a dose.
The Linus Pauling Institute reports that CoQ10 may weaken warfarin and advises an INR check (NCCIH, Coenzyme Q10) (Linus Pauling Institute, Coenzyme Q10).

|---|---|---|
| Turmeric extract | No specific interaction named | Ask your pharmacist |
| Coenzyme Q10 | May weaken warfarin | Ask about INR checks |

FAQ01
Synaptril questions people ask
Does curcumin thin the blood?
The sources we hold do not say so. NCCIH names no specific drug interaction for turmeric. Because herbs and medicines can interact, ask your pharmacist before combining curcumin with a prescribed blood thinner.
Should I stop turmeric before surgery?
Ask your surgeon and pharmacist. We hold no source that gives a stop date, so we will not invent one.
Is turmeric in food a problem with blood thinners?
Our sources speak about supplements, not meals, and name no interaction. A capsule is a concentrated extract, so ask.
