This depends on your baseline markers and health measurements, assessment and any recommendations we have made. Some people find once is enough, others follow the programme each month. For the majority of reasonably healthy people, once or three times a year is sufficient, ideally consecutive months. You may like to try the five-day course and then check in with us afterwards to decide if and when you’d like to repeat it. If you’d like to try the programme for three months, we can also carry out a simple blood test before and after to see how your biomarkers have changed and therefore ascertain how ProLon has helped you.
