Chaga extract comes from a fungus that grows on birch trees. It supplies antioxidants like melanin and beta-glucans. People use it to support immune function and fight oxidative stress. Many also seek it out for its adaptogenic qualities, which may help the body manage stress.
You can take chaga as a liquid tincture, powder, or capsule. Most people take it in the morning or early afternoon. Taking it with meals may improve absorption.
Use caution if you take diabetes medication. Chaga might affect blood sugar control. Avoid it if you are on blood thinners or have an autoimmune condition.
