In an interview with Athletech News, American tennis player Ben Shelton described his supplement routine, the role of his performance team and why third-party testing matters to him amid tennis anti-doping rules. He also discussed the demands of sponsorship work and said he may want a deeper business role with brands in some categories.
American tennis player Ben Shelton told Athletech News that he works with his performance team to refine a regular supplement routine and relies on third-party testing and NSF certification as reassurance amid the sport’s anti-doping rules. In the same interview, Shelton discussed his sponsorship with supplement company Thorne, saying that trust in a product and respect for an athlete’s time shape whether a brand partnership works for him.
Shelton described using magnesium bisglycinate before bed, whey protein isolate after matches, electrolytes during play and creatine. He said he has become more deliberate about consistency and timing as his performance demands have increased. The products and routine he described are his personal choices; the interview does not establish that they produce the same effects for other athletes.
He said selecting what to take is a collaborative process with his performance team, involving trial and error rather than simply adding products. Shelton said the aim is to identify what works for him, while recognizing that individual routines differ. He also said the Thorne products he uses are third-party tested and NSF certified, which he considers helpful in reducing concern about possible contamination.
On sponsorships, Shelton said he values endorsing products he actually uses and trusts. He also praised Thorne for being mindful of his schedule, which must accommodate training and competition as well as campaign commitments. Shelton said he might want a more hands-on role in a brand’s business or product development in some categories, but joked that he is not suited to formulating supplements.
The Stakes Behind Athlete Endorsements
Shelton’s comments show how performance routines and commercial endorsements can overlap in elite sport. When an athlete promotes supplements they say they use, consumers may treat that experience as a recommendation. Shelton framed his own routine as personal and said finding a suitable lineup required input from his team and experimentation, rather than suggesting one formula is right for everyone.
His remarks also highlight a practical concern for athletes: anti-doping rules make product choice consequential. Shelton said testing and certification give him peace of mind, but his account is not independent verification that every product or batch is free of prohibited substances. For brands, his comments point to another part of a partnership that audiences do not always see: campaign schedules must fit around a demanding competition calendar.

Shelton’s Routine and Thorne Deal
The interview followed Shelton’s run to his first Grand Slam final at the U.S. Open. Athletech News described it as the biggest major run of his career. The report noted that he came within one match of becoming the first American man to win a Grand Slam singles title since Andy Roddick in 2003; that historical comparison describes the stakes of the final, not a title Shelton won.
In the interview, Shelton connected his increasing attention to routine with the demands of professional tennis. He said his supplement habits generally remain consistent across different points in the season, while also emphasizing that choices are made with his performance team. The report centers on his perspective and does not provide independent medical or sports-science analysis of the products.
“Getting to the level where I’ve been required making a concerted effort to be consistent with what I take, not missing days and staying on schedule for certain cycles.”
— Ben Shelton, speaking to Athletech News
What the Interview Does Not Establish
The report does not provide independent evidence of the supplements’ effects on Shelton’s performance, recovery or sleep, nor does it detail dosages, medical oversight or product-specific testing records. Shelton’s descriptions of benefits, including his comments about creatine and magnesium, are his own account and should not be read as established outcomes for other people.
The source also does not specify the exact scope or terms of his Thorne sponsorship, whether Shelton receives compensation or other benefits, or whether his product routine is subject to formal review. It does not identify a planned business or product-development role for him. His remarks about possible future involvement were broad and conditional.
No New Venture Announced
Shelton did not announce a new supplement, business project or change to his partnership in the interview. For now, the concrete development is his account of how he approaches his routine and sponsorship obligations. Any future move into product development or a broader business role remains speculative unless Shelton or a company announces specific plans.
Readers seeking details beyond his personal experience would need further information from Shelton, Thorne or his performance team, including product testing documentation and the basis for any performance-related claims. The interview itself does not set out a date for additional announcements.
