**Berberine** at 500mg per capsule puts you right at the floor of the clinically studied range (500–1,500mg/day) for supporting healthy blood sugar, insulin sensitivity, and lipid levels. The evidence behind berberine is strong — multiple meta-analyses show meaningful effects on fasting glucose and triglycerides.

The form is berberine hydrochloride from Indian barberry root, the same standard form used in most clinical research. Standard berberine has low oral bioavailability (~5%), so taking it with a meal as the label suggests helps with both absorption and the GI discomfort berberine is known for.

The catch is the label directs you to take just one capsule daily — keeping you at the minimum studied dose. The strongest clinical results come from 1,000–1,500mg in divided doses (2–3 times daily with meals). If metabolic support is your goal, you'd likely want to take 2–3 capsules spread throughout the day, which means the 60-count bottle lasts 20–30 days instead of two months.
