Nutrition X will again provide supplements for Rovers throughout the 2019/20 Sky Bet League One campaign.
Nutrition X offers a range of products and supplements to support athletic performance across a range of disciplines.
Rovers head of sports science Rob Lee said: “I’m really pleased Nutrition X have agreed to continue working with us, their supplements play a key role in helping our players be in the best possible condition when they are out on the pitch.
“They help optimise performance on the pitch, but also with the recovery afterwards to ensure the players are ready to go again at the best possible level.”
