Bilberry Extract Side Effects

Bilberry Extract Side Effects

Bilberry extract is generally considered safe when taken in recommended doses, but there are some potential side effects to be aware of:

Allergic reactions: Although rare, some people may experience allergic responses to bilberry due to its tannin content. If you are allergic to tannin-containing foods like coffee, tea, or blueberries, you should avoid bilberry.

Bleeding risk: Bilberry may interact with blood-thinning medications like warfarin, NSAIDs, and aspirin, potentially increasing the risk of bleeding. It's best to avoid bilberry if you take these drugs or have a bleeding disorder.

Hypoglycemia: Bilberry can lower blood sugar levels. If you have diabetes and take medications that affect blood sugar, bilberry may enhance their effects, potentially causing hypoglycemia. Monitor your blood sugar closely if using bilberry.

Pregnancy and breastfeeding:
The safety of bilberry supplements is unknown for pregnant or nursing women, so it's best to avoid them.

Interactions with other supplements:
Bilberry may interact with other herbs that lower blood sugar or affect blood clotting, such as garlic, ginger, ginseng, and fenugreek. Avoid using bilberry with these supplements.

The long-term safety of high-dose bilberry supplements is also unknown. Most experts recommend not exceeding 60 grams of dried bilberries per day. If you experience any adverse effects, discontinue use and consult your doctor.
