Most people take their full amount in the evening, 30-60 minutes before bed, rather than spreading it across the day.

A starting point based on general practice, not a personalised recommendation. Hold this routine steady for a week before changing anything, and speak to your doctor or pharmacist if you take medication.

How this calculator works

We start from a daily amount that reflects how noticeable your complaint is and scale it modestly with body weight. The area you select determines how the amount is spread across the day, and the oil strength is then chosen so a single application lands at a practical number of drops. There is no clinically established CBD dosing formula: this is a reasonable rule of thumb, not a prescription.

Use the result as a starting point, hold it steady for a week, and adjust from there based on your own experience.
