Questions people actually ask
Is this just a fibre supplement?
Kuro Kosen is a metabolism-focused botanical drink, not simply a fibre product. The formula combines NUTRALLAX® prune essence and black tea with soluble wheat fibre and other botanical ingredients. It is designed to complement a weight-management routine, and comes in individually packed sachets that you mix with water.
How long until I notice something?
Everyone’s routine and experience are different, so there is no fixed timeline that applies to everyone. Follow the directions on your current pack and consider Kuro Kosen as one part of an overall routine that includes balanced meals, movement and sleep. If you have a health condition or take medication, ask a healthcare professional for advice.
