Comparing the four

What berberine is

Berberine is a bright yellow, very bitter plant alkaloid found in barberry, goldenseal and related shrubs, with a long history in traditional herbal practice. It has no authorised health claim in the UK, so ignore social media promises: we list it by content and strength only. Most people take it with meals, at the serving on the label.

Check before you buy

  • Medicines: berberine is known to interact with a number of prescription medicines. If you take any, ask your pharmacist or GP first.
  • Pregnancy and breastfeeding: not suitable.
  • Safety review: in 2026 the European Food Safety Authority said in a draft opinion that it could not set a safe intake level for berberine in supplements, and the UK's Committee on Toxicity is considering it. Keep to the label serving.

Berberine: your questions answered

How much berberine is in each product?

Applied Nutrition gives 1000mg a day in two capsules and Source Naturals gives 500mg per capsule. For OstroVit and Essensey, the strength per serving is on the label.

Is berberine vegan?

Berberine itself is plant-derived. Applied Nutrition uses vegan capsules, OstroVit tablets are labelled VEGE and Source Naturals uses vegetarian capsules.

Can I take berberine with medication?

Ask your pharmacist or GP first. Berberine is known to interact with a number of prescription medicines.

Why does berberine come in capsules rather than powder?

It is one of the most bitter plant compounds and stains bright yellow, so capsules and tablets are much easier to take. Swallow them whole with water and a meal.

What is AstraGin in Applied Nutrition Berberine?

AstraGin is a branded blend of astragalus and Panax notoginseng extracts that Applied Nutrition adds to its formula. It is listed on the label alongside the berberine.
