I am pretty experienced with supplements and health foods in general. I ordered this after reading reviews on countless products. I started adding 1 TSP a day into my morning smoothie. I took it for about a week and a half before I realized it was causing me to have acne for the first time in 10 years! I was waking up daily with new spots. I also felt lightheaded after taking this, which only lasts a few hours. I am returning due to the fact that I stopped taking this a few days ago and the new acne spots are healing with no new ones. It might work for someone, but not me! UPDATE: I have changed my 3 star review to 5 stars. I realized that my skin was literally detoxing after starting a healthier daily regimen. The acne ended up slowing down, and then completely stopped. One day I just woke up and my skin was glowing, dark circle fading, etc. My skin is smooth again. The nausea and light headedness went away. I am now up to 1.5 teaspoon a day and am going to keep it that way. I really do like this supplement, I feel overall healthier and like I have more energy. I will likely buy this again when it is gone
