From gummies to teas to dog treats, CBD oil has exploded in popularity. The marijuana extract has been credited with helping people alleviate such problems as anxiety, sleeplessness and inflammation. And because it’s devoid of THC, there isn’t the intoxicating high typically produced by marijuana. A new drink company is hoping to bring some of these benefits to the sports community.

Launched in collaboration with Denver Broncos great Terrell Davis, Defy is the first mainstream CBD beverage targeted at athletes. Each 16-oz. bottle contains 20mg of performance spectrum hemp extract, along with ingredients such as electrolytes, B vitamins and coconut water. Consumption is recommended before, during or after exercise. The formula is intended to improve athletic performance by enhancing focus and effort during activity, while speeding the recovery process. 

Research on the benefits of CBD is still in the nascent stages, but count John Isner as one of its proponents. The world No. 15 and top-ranked American male, Isner is the first pro tennis player to endorse Defy. The partnership was announced at the BB&T Open in Atlanta.

"I play a sport where taking a single point off can be the difference between winning and losing a match and Defy is a product specifically intended to put me in a position to perform on every single point,” explained Isner. “It’s been great getting to know Defy as a company and I look forward to working with them to help people achieve improved performance through CBD."

Defy is currently offered in three flavors: Lemonade, Orange Mango and Mixed Berry. It’s also not cheap—a six-pack costs $48. If you’re interested in seeing if CBD can make a difference in your performance, you can order at
