ANSWERED QUESTIONS
Is there an FDA recommendation for daily isoflavone intake?
Answered by Katy Raneri - October 5, 2011
Not at this time. The FDA has approved a health claim for soy protein that states, “25 grams of soy protein, along with a diet that is low in saturated fat and cholesterol, may help reduce the risk of heart disease.”1 One gram of soy protein contains approximately 2-3 mg of isoflavones. 25 grams of soy protein contains approximately 60-75 mg of isoflavones. To learn more about isoflavone content in food, visit the USDA Isoflavone Database.
