Short answer

We found no documented interaction between Chlorella and Omega-3 in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

Chlorella

What it is: A green freshwater alga sold as a supplement.

What the research says: A review of 10 trials found modest drops in total and LDL cholesterol. Only 2 of those trials checked what the supplements actually contained.

Cautions

• That review didn't assess safety, and we didn't find a reliable safety review.

Medicines to check

• Talk to your clinician if you take any medicine

Omega-3 (fish oil)

What it is: Fats (EPA and DHA) found in fish that are part of every cell membrane and matter for the heart, brain and eyes.

What the research says: EPA and DHA lower triglycerides. Heart experts recommend eating fish; they don't recommend omega-3 supplements for people at low heart risk.

Cautions

• The FDA advises no more than 5 g a day of EPA plus DHA from supplements.
• Side effects are usually mild: fishy taste, heartburn, nausea, loose stools.

Medicines to check

• Warfarin and other blood thinners: high doses may raise bleeding risk
