Common questions

What supplements help with weight loss?
No supplement replaces a calorie deficit, but berberine and chromium support blood-sugar control, fibre (psyllium) supports fullness, and protein preserves muscle while dieting.
Does berberine help you lose weight?
Berberine modestly improves insulin sensitivity and metabolic markers, which can support weight efforts, but it's a helper, not a substitute for diet and activity.
