Berberine: What It Is and What to Know Before You Buy

Berberine is one of the most searched supplement ingredients in Australia, and one of the most misrepresented online.

This guide sticks to what it actually is: where it comes from, the forms sold here, how it is usually taken, and the questions worth putting to your GP before you start.

What is berberine?

The US National Center for Complementary and Integrative Health describes berberine as a substance found in a variety of plants, including goldenseal, barberry and Oregon grape. It has a distinctive bright yellow colour.

It has a long history of use in traditional herbal practice in several parts of the world. Today it is sold in Australia as an oral supplement rather than as a food.

Where it comes from

Commercial berberine is extracted from plant material and standardised, which is why supplement labels quote a specific amount of the compound rather than an amount of the plant.

What forms is berberine sold in?

In Australia berberine is almost always sold as an oral supplement. Capsules are the most common format because the compound is bitter.

• Capsules. The standard format, and the easiest to take consistently.
• Powder. Less common, and the taste is the reason.
• Combination formulas. Berberine alongside other ingredients in one product.

Berberine HCl

You will often see berberine hydrochloride, or berberine HCl, on a label. That is a salt form of the compound, used because it is more practical to work with in a supplement.

You can see the oral products we stock in weight loss supplements and weight loss capsules.

How do people take berberine?

Serving sizes and timing vary between products, so the label on the specific product you have bought is the instruction to follow. It will state the serve and how many serves a day the product is designed around.

Because it is bitter and can be unsettling on an empty stomach, it is commonly taken with food. Many products are designed to be split across the day rather than taken all at once.

Who should not take berberine?

This is the part worth reading before the product pages.

• If you are pregnant or breastfeeding. The NCCIH states that berberine is likely to be unsafe for infants and may also be unsafe during pregnancy or while breastfeeding, because of possible effects on the fetus or infant.
• If you take prescribed medication. Berberine can interact with a range of medicines, so check with your GP or pharmacist first.
• If you are managing a medical condition. Speak to your doctor rather than self-selecting.
• For children. These products are formulated for adults.

Common complaints

Digestive upset is the most commonly reported issue, which is part of why it is usually taken with food and split across the day. If it does not agree with you, stop taking it and speak to a pharmacist.

What should I look for when buying berberine in Australia?

Labels vary more than the front of the pack suggests, so compare on the panel.

• The amount per serve. Quoted per capsule and per daily serve. Both matter.
• Serves per container. This is what makes a price comparison meaningful.
• Single ingredient or a blend. A combination product may suit you, but you should know what else is in it.
• Whether it is oral. We only sell oral supplements that are legal to buy in Australia. We do not sell injectables or research vials.

Is berberine a replacement for medication?

No. Berberine is a supplement. It is not a substitute for anything your doctor has prescribed, and it should not be used as one.

If you are looking at berberine because of something a doctor has raised with you, the useful next step is a conversation with them rather than a purchase. They know your history and what you are already taking.

Where a supplement can fit

Supplements sit around the edges of the things that carry the most weight: how you eat, how you move, how you sleep. That ordering is worth keeping in mind whatever you decide about berberine.
