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.
