What about olive oil supplements?

“Taking olive oil supplements is not recommended as you can likely get all of the benefits from the food itself,” Thomason said. “The serving size and minimum effectiveness in a supplement are likely hard to find when you could cook more often with olive oil and reap the same benefits.”

Danahy agrees but notes that if you add supplements to an already unhealthy diet, there probably won’t be a benefit.

“They are safe, but it’s important to note that you won’t get any benefit if you add a supplement to an unhealthy diet. I’d prefer to see someone using olive oil as part of a healthy diet,” she said. “In fact, in this study, the lowest risk was from eating olive oil along with a healthy diet. If a person wants an extra boost, they can consider adding a supplement.”
