C60 is non-toxic and safe in vivo (living in the body).
It is very difficult to consume too much C60. One scientific study tested the toxicity levels of C60 in rats, and ironically observed that C60 prolonged the rat’s lifespan by 90%. However, it is possible to consume too much MCT oil, which we use in our unique C60 blend. If you notice digestive side effects, such as loose stools, we suggest halving your dosage of Organic Reflection C60 until the issues settle, then slowly increasing your dosage. While scientific studies suggest users can take up to 5 mls per day, we recommend taking 2 ml per day to feel the health benefits. However, everybody is individual and react differently to supplements, so safely experiment to find your own balanced dosage.
