For health maintenance, take 6 drops three times a day or as directed by your practitioner. For the best benefit we recommend to take 1 drop/kg of body weight daily, divided into 3 doses. For conversion from pounds to kilograms multiply pounds by 0.454. For example, if you weigh 150 lb, it is equivalent to 68 kg. You should take 68 drops per day divided into 3 doses. This means 23 drops three times a day.
