I'd consider buying a larger bottle.
Verified Purchase
The product is mainly to support metabolism and glucose levels, promoting overall health. The ingredients are simple and tasteless. Since there are only 10 capsules, I don't feel much, but I will consider buying a large bottle to try it out.

Blood sugar levels do not rise
Verified Purchase
I take it after dinner. Usually after dinner I would pass out and sleep on the sofa. But after I take this berberine and eat, I don't feel sleepy. My weight hasn't changed the next day, so I think it's keeping my blood sugar levels in check.

The bitter taste is the traditional Chinese medicine Coptis chinensis. Berberine supplementation is expected to enhance insulin sensitivity, blood sugar control, and blood lipid regulation. Activating AMPK to realize its potential health benefits.

Like the weight loss shot
Verified Purchase
One in the morning with food or after food and you don't feel like eating anything. Lowers sugar levels so you don't feel like eating sweets. Take seven from half a meal. Be careful, it can make you nauseous at first, let your body get used to one pill with food and then see the reaction.

Berberine, also known as berberine, is a natural alkaloid extracted from various plants and has a long history in Ayurvedic medicine. It activates AMPK, a key enzyme in the body. Its antimicrobial properties help balance the gut microbiome and may treat certain gastrointestinal infections. However, berberine may interact with certain medications (particularly those for diabetes and heart disease), so caution is advised before use.

Great quality from Zahler — I would definitely buy a larger bottle next time
Verified Purchase
This berberine supplement is a great addition to any metabolic or gut support routine. Even with a small trial size (10 capsules), I noticed a slight improvement in digestion and blood sugar balance. It's helpful to test how your body reacts before committing to a full-size bottle. The capsules are easy to take, with no unpleasant aftertaste. Great quality from Zahler — I would definitely buy a larger bottle next time."
