Astaxanthin CWS (Cold Water Soluble) is a food-grade water-dispersible formulation of natural astaxanthin, a powerful carotenoid antioxidant, designed for easy incorporation into beverages and water-based food systems.We supply bulk Astaxanthin CWS sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Astaxanthin CWS is widely used in antioxidant drinks, tablets, functional food fortification, natural food colouring and skincare formulations.
Astaxanthin CWS is a microencapsulated, cold-water-dispersible powder form of astaxanthin — a keto-carotenoid pigment naturally found in Haematococcus pluvialis microalgae, salmon, shrimp and krill. Astaxanthin is recognised as one of nature's most potent antioxidants (6,000× stronger than vitamin C).
The CWS formulation uses starch or gum-based encapsulation to enable instant dispersion in cold water without oily residues. This makes it ideal for beverages, supplements and functional foods.
