What is soy?
Soy is a grain that is grown throughout the world. Recent research has shown that the isoflavones are considered to be the active component in soy. Several reports have recently been published on the benefits of soy. The U.S. Food and Drug Administration recently released evidence that shows soy protein supplementation may play a role in reducing the risk of heart disease. Additional benefits including a minor reduction in the frequency and intensity of hot flashes, and a possible reduction in the risk of developing osteoporosis require further scientific evaluation. Isoflavones are thought to be the active ingredients in soy.
Soy is available in capsules, tablets, and powder mixes. Soy can also be consumed from foods such as soy milk or tofu. Taking soy in a supplement rather than from foods may make it easier to get a consistent dose every day.
Soy is generally well tolerated with few reported side effects. It may increase the length of the menstrual cycle and could potentially lead to lower estrogen levels.
