Soy capsules are a dietary supplement that contains soy isoflavones extracted from soybeans. They are often taken as a natural remedy for menopause symptoms such as hot flashes and night sweats. Soy capsules may also offer other health benefits, such as reducing the risk of heart disease, improving bone health, and lowering cholesterol levels. It is important to note that soy capsules may interact with certain medications, such as blood-thinning drugs, and may not be safe for everyone. It is always a good idea to consult with a healthcare professional before taking any dietary supplements, including soy capsules.
