Soy fiber comes from soybean husks or the bean itself. This soluble powder dissolves in water and forms a gel. That gel slows sugar uptake in the gut and binds to cholesterol, helping your body clear it. These actions support steady blood sugar and healthy cholesterol numbers.
Mix the powder into water, juice, or a smoothie alongside meals. Some people prefer capsules. Start with a small dose and drink extra fluids. Build up slowly to avoid gas or bloating. If you take any medication, wait at least two hours before or after your fiber dose, because the gel can block absorption.
Skip this supplement entirely if you have a soy allergy.
