Can I take Cod liver oil and Ginseng together?

Why this happens

Cod liver oil contains omega-3 fatty acids, which have a mild blood-thinning effect. Ginseng (particularly Panax ginseng) can also interfere with how blood cells (platelets) stick together. When used together, these effects can add up, increasing the overall blood-thinning effect.

It is generally best to use caution when combining these two supplements. If you notice unusual bruising, frequent nosebleeds, or bleeding gums when brushing your teeth, stop taking them and speak to your GP. You should stop taking both supplements at least two weeks before any planned surgery or dental work. If you are already taking prescription blood thinners (like warfarin or aspirin), do not take this combination without consulting your doctor first.

Pregnancy

Do not take cod liver oil if you are pregnant or planning to become pregnant. It contains high levels of Vitamin A (retinol), which can harm the development of an unborn baby.

Diabetes

Ginseng can lower blood sugar levels. If you have diabetes, monitor your blood sugar closely as your medication dosage may need adjustment to prevent hypoglycaemia.

Surgery or bleeding disorders

Both ginseng and cod liver oil can thin the blood and increase the risk of bleeding. You must stop taking them at least two weeks before any scheduled surgery.

Alcohol

It is best to avoid or strictly limit alcohol when taking cod liver oil. Both alcohol and high doses of vitamin A (found in cod liver oil) can put strain on the liver; combining them may increase the risk of liver toxicity.

It is best to avoid or strictly limit alcohol when taking ginseng. Ginseng may speed up the rate at which your body breaks down alcohol, but it can also interfere with how alcohol affects your central nervous system.

Caffeine (Coffee, tea, energy drinks)

Ginseng can act as a stimulant. Combining it with caffeine may increase the risk of side effects such as a racing heart (tachycardia), high blood pressure, nervousness, and insomnia.

Foods with anticoagulant properties (e.g. Garlic, Ginger)

Ginseng may interfere with blood clotting. Taking it alongside large amounts of other foods known to thin the blood may increase the risk of bruising or bleeding.
