The best berberine supplements 2026 – tried and tested
When choosing the best berberine supplements, we've prioritised high bioavailability, trusted brands and formulations with minimal fillers
Berberine is a natural compound found in plants that has been used for centuries in traditional medicine. Today, it’s gaining attention as a supplement people take to help maintain healthy blood sugar, support metabolism and look after heart health.
With so many products on the market, it can be tricky to know which ones are reliable. Some provide well-absorbed forms of berberine at research-backed doses, while others may rely more on marketing than quality. Checking the dose, ingredient form, number of capsules, and third-party testing can make it easier to pick a product that fits your lifestyle.
In this guide, we’ve reviewed the top berberine supplements, looking at dosage, ingredient quality, value for money and practical considerations, so you can see which options stand out.

How we tested berberine supplements
To put together our edit of the best berberine supplements, we combined expert nutrition input with hands-on testing. Nutritionist Kerry Torrens helped guide the process, drawing on the current evidence base around berberine and its role in metabolic health, blood glucose management and lipid balance. This included consideration of appropriate dosing, formulation quality and safety for daily use.
All supplements were tested in the same way. We focused on berberine capsules and softgels rather than powders or drinks, as these are the most common versions available. Each product was taken according to the manufacturer’s instructions, with observations recorded using our in-depth testing criteria.
The Good Food team reviewed supplements from a range of brands, spanning different price points and formulations, from single-ingredient berberine to more complex blends designed to enhance absorption or provide additional metabolic support. The key areas we assessed were:
- Dosage and potency: how much berberine is provided per daily serving and whether this aligns with amounts used in published research
- Formulation and absorption: whether the product uses standard berberine HCl or enhanced delivery systems such as liposomal or synergistic blends
- Ingredient quality: the presence of unnecessary fillers, additives or artificial ingredients
- Ease of use: capsule size, serving size and how easily the supplement fits into a daily routine
- Suitability for dietary requirements: including vegetarian or vegan suitability where relevant
- Value for money: cost per day compared with similar products on the market
Best berberine supplements to buy in 2026
NOW Foods Berberine Glucose Support
Available from: iHerb (£24.23)
Best natural berberine supplement
Star rating: 5/5
This well-priced softgel supplement provides 400mg of berberine hydrochloride per capsule, with three daily giving 1200mg, matching research-supported ranges for metabolic health. We found it easy to include in daily routines, with three to be taken a day with food, and the softgels are smooth to swallow. At around 27p per day, it’s one of the most cost-effective options we tested.
The formula is free from gluten, dairy and soy but contains gelatin, so it’s not suitable for vegetarians or vegans. MCT oil is included, which may support absorption, although evidence for a significant clinical effect is limited. Overall, this is a simple, reliable berberine option at strong value.
Available from:
Thorne Berberine 1000 Milligrams
Available from: iHerb (£35.94)
Best high-strength berberine supplement
Star rating: 5/5
Each capsule provides 500mg of berberine hydrochloride, with two capsules daily reaching 1000mg and three capsules 1500mg. We were impressed with the consistent formulation quality and the GMP-certified, NSF Certified for Sport manufacturing, which gives confidence in dose accuracy.
The capsules are free from gluten, dairy, and soy. The cost per day is higher at around £1.20 for two capsules, but the reliability and clinical-grade standards make it ideal for experienced users comfortable with higher doses.
Available from:
BIOptimizers Berberine Breakthrough
Available from: Bioptimizers (£59.99)
Best enhanced absorption berberine supplement
Star rating: 5/5
This softgel stood out for absorption support, combining 400mg berberine hydrochloride with MCT oil. Three capsules daily deliver 1200mg and we found them comfortable to swallow. The formulation may benefit users with digestive sensitivity or those looking for better uptake than standard capsules.
It is free from unnecessary additives, but the premium price reflects the advanced delivery system. For those prioritising technology-driven absorption, this product performed well in our tests.
Available from:
Renue by Science CardioMAX Liposomal Berberine
Available from: Healf (£39.49)
Best liposomal berberine supplement
Star rating: 4.5/5
This supplement targets both cardiovascular and metabolic health, delivering 100mg of liposomal berberine per daily serving, designed to support blood sugar balance and lipid metabolism while improving absorption through a liposomal delivery system.
The formula is combined with red yeast rice and CoQ10, two ingredients commonly included in heart-health supplements. Red yeast rice contains naturally occurring monacolins that can help support healthy cholesterol levels, while CoQ10 plays a role in cellular energy production and acts as an antioxidant that supports heart and mitochondrial function.
We found the formulation thoughtfully designed and easy to swallow.
The daily cost is higher at around £1.32, but the additional cardiovascular-supporting ingredients may justify the price for experienced users in search of a targeted, premium formula.
Available from:
Designs for Health Berberine Synergy
Available from: Healf (£47.99)
Best berberine complex for metabolic health
Star rating: 4.5/5
We liked this complex for pairing 500mg berberine hydrochloride per capsule with alpha-lipoic acid, providing 1000mg daily across two capsules. This combination supports metabolic and cardiovascular health and the vegetarian, non-GMO capsules are free from gluten, dairy and soy.
The label is transparent and, while the daily cost is around 97p, the additional co-nutrient justifies the higher price for those wanting broader metabolic support.
Available from:
Designs for Health Berberine Evail
Available from: Healf (£48.99)
Best berberine softgel
Star rating: 4.5/5
This softgel uses an Evail-emulsified delivery system to improve absorption and ease digestive tolerance. This is a formulation technique that turns nutrients into very small emulsified particles (tiny droplets) so they are absorbed more efficiently in the digestive system, especially nutrients that are normally hard to absorb.
Each softgel provides 400mg of berberine hydrochloride, with two softgels giving 800mg daily. Capsules are smooth and easy to swallow.
The formula contains gelatin and soy, making it unsuitable for vegetarians or vegans. While the total daily dose is slightly lower than some alternatives, the emulsified system may appeal to those sensitive to standard capsules. Daily cost is about £1.63.
Available from:
Natroceutics Berberine Complex
Available from: Healf (£38.50)
Best premium berberine complex
Star rating: 4.5/5
This multi-ingredient formulation provides 550mg of berberine hydrochloride per capsule (including 50mg delivered via a liposomal form), alongside liposomal chromium for additional metabolic support. Chromium contributes to normal macronutrient metabolism and helps maintain normal blood glucose levels, which may complement berberine’s role in supporting metabolic health.
In our testing, it was well-tolerated and the formulation includes a dual-delivery approach, combining standard berberine with liposomal berberine designed to support improved absorption and sustained activity in the body.
Ingredient sourcing and product standards also appear transparent. The supplement is manufactured to GMP (Good Manufacturing Practice) standards, labelled as vegan-friendly and uses fully recyclable packaging, all of which can indicate attention to quality.
We believe this is best suited for users already familiar with berberine who want a broader metabolic-support formulation. Absorption is enhanced through the dual-delivery system, and the premium price reflects the practitioner-style positioning.
Available from:
ProHealth Longevity Berberine Pro
Available from: iHerb (£28.53)
Best berberine supplement for longevity focus
Star rating: 4.5/5
Each capsule delivers 600mg of berberine hydrochloride, with two capsules daily providing 1,200mg, a dosage commonly used in metabolic health research. We appreciated the minimalist formulation and well-balanced dose, which makes it well suited to people following a long-term supplement routine focused on metabolic health.
Unlike some formulations that add multiple additional ingredients, this product keeps the formula simple and focuses on delivering a clinically relevant dose of berberine without unnecessary fillers or extras. This straightforward approach may appeal to users building a longevity-focused supplement stack who prefer to control and combine individual ingredients themselves rather than relying on complex blends.
Manufactured in a GMP-certified facility, absorption relies on standard capsules. At around 77p per day, it offers good value for a clinically supported dose.
Available from:
NMN Bio Berberine and Milk Thistle
Available from: Healf (£29.49)
Best berberine supplement with liver support
Star rating: 4/5
This combination includes 400mg berberine hydrochloride per capsule alongside milk thistle. Milk thistle is commonly included in formulations like this because it contains silymarin, a compound known for supporting normal liver function and antioxidant activity. As the liver plays an important role in regulating cholesterol, blood sugar and fat metabolism, pairing milk thistle with berberine may help support overall metabolic health.
One to three capsules daily provide 400mg to 1200mg depending on your goal. Capsules are vegan, non-GMO and manufactured in a GMP-certified facility.
We found this product suitable for those who would like to combine metabolic and liver support in one supplement, with a sensible formulation and moderate price.
Available from:
Vitabright Berberine HCL Capsules
Available from: Vitabright (£19.99)
Best high-purity vegan berberine supplement
Star rating: 4/5
This straightforward supplement provides 500mg of berberine hydrochloride per capsule, standardised to 98 per cent purity, meaning almost all of the extract is the active compound. Taking the full suggested intake of three capsules daily (1,500mg) falls within the dose range commonly used in studies exploring blood sugar control, metabolism and appetite regulation, making it a solid option for metabolic support.
The routine is simple – one capsule before meals, up to three times a day. The formula is also vegan and free from common allergens like gluten and dairy, with minimal fillers (just rice flour and a plant-based capsule). At roughly 22p to 66p per day depending on dose, it’s also a competitively priced option for a high-purity berberine product.
However, the formula uses standard berberine hydrochloride, which is the most common form but is not designed for enhanced absorption. Some newer supplements use delivery systems like liposomal or dihydroberberine, which may help the body absorb the compound more efficiently.
Available from:
Weight World Pure Berberine Capsules
Available from: Weight World (£18.49)
Best budget berberine supplement
Star rating: 4/5
Each capsule provides 500mg berberine hydrochloride and is taken once daily. The vegan, gluten-free capsules contain minimal additives, making them simple and practical for cost-conscious users. We liked the affordability (around 15p per day) and straightforward formulation. There are no co-nutrients and absorption is standard, making it ideal for basic supplementation.
Available from:
Bettervits Berberine Capsules
Available from: Boots (£35)
Best simple berberine supplement
Star rating: 4/5
Bettervits offer a straightforward berberine supplement providing 500mg of berberine hydrochloride per capsule, which is broadly comparable to many other products in this list that also deliver around 500mg to 600mg per serving. This makes it an accessible option for those who want a standard, research-aligned dose without committing to a more complex formulation.
Where this product stands out is its simple, no-frills ingredient list. The formula contains berberine hydrochloride alongside basic capsule ingredients such as brown rice flour and plant-based capsule material, with no additional herbal extracts or absorption enhancers.
Compared with some other supplements in the list that include liposomal delivery systems or added nutrients such as chromium or milk thistle, this product focuses purely on delivering berberine itself. That may appeal to users who prefer a single-ingredient supplement they can combine with other nutrients separately.
However, the simplicity does mean absorption relies on standard berberine hydrochloride, whereas some newer formulations use liposomal delivery or added ingredients to improve uptake. It’s also slightly more expensive than some similar basic formulas we tested.

What is berberine and why should I take it?
Berberine is an alkaloid extract found in a variety of plants, although barberry (Berberis vulgaris) is the primary source, with goldenseal and Oregon grape being common alternatives. With a long history of use in Ayurvedic and Chinese medicine, berberine has been used for infections including the herpes simplex virus, skin disorders like acne and atopic dermatitis, as well as digestive conditions.
However, it is important to note that berberine is not a cure for any medical condition and evidence for many uses is still emerging. More recently interest has focused on berberine’s application for:
- Weight loss, especially for those with metabolic conditions like type 2 diabetes
- Blood sugar control
- Heart health, including cholesterol management
- Gut health
- Poly-cystic ovarian syndrome (PCOS)
- Inflammatory conditions
- And mood disorders, including mild depression
Berberine should be viewed as a complementary supplement rather than a treatment or cure, and it should not replace prescribed medications or professional medical care.
When choosing a berberine supplement consider your health goals, as some products are designed with certain objectives in mind such as heart health, blood sugar control or supporting metabolism. These products often combine berberine with other nutraceuticals, so always check the label to ensure that the product is suitable for your circumstances.
What form of berberine should I take?
Available in capsules, tablets, soft-gels and powders, berberine hydrochloride (berberine HCl) is one of the most studied and widely available forms. Although berberine is a natural product it can be synthetically made for commercial use, with the effectiveness of the product depending more on dosage and quality, than origin.
Nutritionist Kerry says: “If more effective absorption is needed (given berberine has poor bio-availability) look for products that use liposomal berberine, dihydroberberine or berberine phytosome. These forms may be more expensive but enhance absorption, allowing lower doses to be used; this may be especially useful if you have a sensitive gut and are likely to experience digestive upset. It’s important to remember, if you supplement with an enhanced berberine form or a product that includes absorption enhancers, like milk thistle, and you take prescribed medications, the product may be more likely to promote a drug interaction.”
Is berberine safe to take daily and what are the side effects?
According to nutritionist Kerry: “For the average, healthy adult, daily use in accordance with product guidelines (typically up to 1.5g daily and in divided doses) is considered safe for periods of about six months.
“Berberine is not recommended for long term use, without breaks, this is because there is limited support to confirm its safety beyond this period. What constitutes a suitable dosage will depend on the condition you wish to address, for example for blood sugar effects a dose of 500mg, taken three times daily after meals, has been reported to work well.”
It should be noted, that there is more for us to learn with regards berberine’s clinical effects and more high-quality studies needed. For example, gender may be relevant, given males report greater improvements in cholesterol levels than females.
If you choose to supplement you should be aware of the common side effects that include digestive upset like nausea, stomach pain, bloating, constipation and diarrhoea. These effects may be seen in those taking doses above 300g per day.
When should I take berberine?
Berberine is generally taken with or shortly after a meal to support digestive tolerance and consistent blood levels.
Who should (and shouldn’t) take berberine supplements?
Those likely to obtain benefit from berberine include people with metabolic disorders including PCOS, insulin resistance and type 2 diabetes as well as those with mildly high cholesterol. However, if you’re on prescribed medications check with your prescribing clinician before supplementing, this is because berberine is known to interact with some medications as it inhibits several liver enzymes that are involved in drug metabolism. This is of particular, but not exclusive relevance, to statins, calcium channel blockers, digoxin and the blood sugar drug, metformin.
Berberine is not suitable for infants because it has been linked to a harmful build-up of the waste product, bilirubin, for this reason it may be unsafe during pregnancy and when breastfeeding.
Nutritionist Kerry adds: “If you’ve been diagnosed with liver or kidney impairment, consult your doctor before using berberine. This is because both the liver and kidneys play a key role in metabolising and removing berberine from the body.”
