At 57, I finished menopause 5 years ago. I began regular exercise program several months ago, and weight loss diet. I lost 20 lbs, including abdominal fat. About a month ago I started taking a vitamin with 800 mg of 'phytosterols' for heart health. Today I had vaginal spotting--out of the blue. Could this be result of phytosterols or weight loss? Years ago I took soy supplements for menopause and could not take them--gave me headaches and made me sick. Just wondering before I plunk down $100 for doctor visit.
