90 capsules with 500mg of berberine per capsule. Natural berberine extract from the berberis aristata plant. Test how much you need, and take 1 to 3 capsules daily. This is a very purified form of berberine which is much stronger than many alternatives you may be used to. Why take berberine? Berberine is popular as a supplement to support weight management and to manage blood sugar levels. Why choose our berberine supplement? Purity - This is the purest extract on the market (98% purity) meaning it doesn't contain the unwanted compounds that can cause side effects in some other products. You can see its purity in the intense yellow colour. No junk - We don't add any artificial additives at all, just a little rice flour to stop the powdery berberine clogging as we fill the capsules. Made in UK - This guarantees GMP rated hygienic manufacturing conditions, no product contamination and fair treatment of workers, among many other reassurances. Lab tested and certified clean - We have the berberine analysed by an independent laboratory to certify that it's free from heavy metals and other toxins.
