E161H - Zeaxanthin

Zeaxanthin (E161h) is a yellow‑orange carotenoid pigment found naturally in foods like corn, orange peppers, and egg yolks. It’s used as a colouring ingredient in some markets and is better known as a component of eye‑health supplements alongside lutein. Regulatory rules vary by country, so you’ll most often see zeaxanthin on dietary supplement labels rather than everyday foods.
