The glamour model-turned-bodybuilder has signed a deal with supplement company JST Nutrition to become the new face of its advertising campaign.
She has created her own range named 'JST Jodie', which includes eight different products such as clothing and bottles.
"I am so proud of what we've developed here and I can't wait for everyone to try them," she said in a statement.
"Let's all get fit together. Eat clean and train dirty."
Jodie Marsh recently revealed that she became depressed following her appearance in Celebrity Big Brother in 2006, but that bodybuilding has turned her life around.
