Animal studies have found benefits with ursolic acid in the diet at 0.05-0.2% of the diet, which is around 10-40mg/kg (based on their weight and food intake) and the estimated human dose equivalent to this is 1.6-6.4mg/kg bodyweight; for a 150lb adult it would be the range of 110-440mg.
The lone human study used the higher end of this range, 150mg three times a day with meals totalling 450mg each day, and found some biological acitivty. Until further research arises, thrice daily dosing of 150mg with meals is recommended.
