I have researched this product and have been using for 6 months now with breaks every 2 months. Since starting the menopause, my energy levels dropped and I was constantly tired and lethargic. My thyroid count was borderline/low. I take 3 drops with water every morning as instructed and it really improves my energy throughout the day and makes me more alert. It has a mild taste when added to water or you could add it to smoothies or juice.
