The Ursolic Acid Dosage That Works (Explained)

Updated: Aug 15

Evidence-Based. Scientifically Reviewed.

Ursolic acid is a novel but seemingly effective supplement for boosting exercise performance, muscle growth, and fat loss.

Most supplements work in a dose-dependant manner, meaning the more you take, the better the effects.

While ursolic acid is the same, once a certain dosage is reached it may actually be detrimental or have reduced effects instead of being beneficial, likely due to myotoxicity. (1)

Recommended Dosage

A typical dosage of ursolic acid is about 150 mg 3x per day. While the dosage that causes myotoxicity is unknown, most studies use this dosage with effectiveness.

However, a lack of research exists around the usage of ursolic acid. Because of this lack of research, I recommend you not to use ursolic acid, purely from a safety standpoint.

If you do decide you want to use ursolic acid, sticking to under 450 mg per day is probably your best option.

Going any higher in dosage is a completely unknown territory as it has not been studied, it may also be less effective.

To summarise, research is severely lacking, but one human trial demonstrated biological activity at 150 mg three times a day with meals totalling 450 mg per day.

Until further research on ursolic acid is conducted, 150 mg three times a day with meals is the best option.
