1. What is Kale Powder?
Kale powder is a concentrated form of fresh kale leaves (Brassica oleracea) produced through low-temperature drying and milling. It retains key nutrients, phytonutrients, and antioxidants in a shelf-stable, versatile powder, suitable for integration into capsules, functional foods, beverages, and cosmetic products. This ingredient allows formulators to achieve consistent bioactivity without the challenges of using perishable fresh greens.
