Five supplements that can have dangerous effects when combined – risk of 'liver damage'

Fish oil and ginkgo biloba

The Journal of General Internal Medicine cautioned in 2005 that taking ginkgo biloba alone can be inappropriate for certain people with bleeding risks.

“Patients using ginkgo, particularly those with known bleeding risks, should be counselled about a possible increase in risk,” explained the report.

Taking omega-3 alongside ginkgo could potentially increase this risk, as fish oil also has a thinning effect on the blood.

To avoid complications, experts recommend taking the pills at least two hours apart.
