Karela powder is a supplement made from drying and grinding bitter gourd into a fine powder. Bitter gourd, also known as bitter melon or karela, is a vegetable commonly used in Indian cooking that has a bitter taste but is rich in nutrients. As a powder, karela can be sprinkled onto food, added to juices or smoothies, or taken as capsules. It's believed to have health benefits like improving blood sugar control, immunity, skin health, and digestive issues, though more research is still needed on the exact effects. The powder has an intensely bitter, pungent flavor.
