Ginger and medications: interactions to be aware of
This article is for informational purposes only and does not replace the advice of a doctor or pharmacist. If you are taking prescription medications, consult your healthcare professional before starting regular ginger supplementation.
Ginger at dietary doses (up to 2 g/day) is safe for most people. Clinically significant interactions primarily concern anticoagulants (warfarin, heparin), antidiabetics, and antihypertensives. High doses (more than 4 g/day) increase the risk of interactions.

FAQ
Can I take INTI if I'm on warfarin?
Discuss with your doctor or anticoagulation specialist. Generally, 1 shot/day is well tolerated, but INR monitoring is recommended when starting.
Does ginger interact with statins?
No clinically significant interaction known with statins. Ginger may even complement their action on cholesterol.
Can I take ginger with aspirin?
Both have antiplatelet effects. The combination can increase the risk of bleeding. At dietary doses (1 shot/day), the risk is generally low, but report it to your doctor.
Safe dietary dose: 1–2 shots/day · 0% sugar · Cold pressed · Belgium
