Your formulas will contain 108 pills in a 10:1 concentration. The 108 pills will last 27 days. They should be taken 2 pills from each bottle twice per day. The month’s supply is based on a woman’s menstrual cycle – 28 days, not the calendar month.  When a woman starts her first bottle, 27 days later the bottle will be finished. The  second bottle will start on the 28th day. As these formulas are ‘practitioner dispense only’ a client would typically revisit their practitioner on the 28th day for assessment and prescription.  The formulas are designed to make a woman’s cycle a regular 28 days. This is why the formulas and dosages are created this way.  The same rules apply to the MenOvance range, it is just easier that way.
