When taking the Oxypowder if the product stops producing results. It is not the product that is not working, you have changed your diet, your stress levels have increased,or your water intake is not what it should be. The usual recommendation for water intake is to take your body weight and divide it by two. This is the number of ounces of water, you will consume per day. However, if you live in a place where the temperature is very hot, thenn you might want to increase water intake. Also, if you are excercising on a regular basis, then you should also increase your water intake. The Oxypowder does require a good amount f water to flush out your toxins. I hope this helps to answer your question.If this does not answer your question, I would try contacting the coampny that makes the Oxypowder , their customer service is great.
