Summary
Chlorella is rich in vitamin K and can reduce warfarin effect. Heparin acts independently of vitamin K, so no real antagonism is expected.
What this interaction means in plain words
Chlorella and Heparin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Vitamin K content does not oppose heparin, which acts via antithrombin; any effect is theoretical.
What to do
No action is needed for heparin. Continue routine aPTT or anti-Xa monitoring.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
