Frequently Asked Questions (FAQ)

We combine science-backed supplements with simple daily habits that help reduce glucose spikes, stabilize energy, and support healthier habits over time.

Most supplement brands offer passive solutions: adding vitamins or nutrients without targeting root causes. Nosu takes an active approach. We help you change habits by shifting how you experience sweetness and how your body processes sugar. Sweet Shield, our flagship product, reduces cravings, blunts the reward from sugary foods, and lowers sugar absorption.

Nosu is headquartered in Leiden, the Netherlands. All our products are researched, formulated, and produced in the Netherlands.

Sweet Shield supports you in three key ways:
