A woman who once worked for Priceline has revealed the success and failures behind launching her multimillion-dollar vitamin empire. Clinical nutritionist Jessica Sepel, 32, and her husband, CEO Dean Steingold debuted on the Financial Review Young Rich List with an estimated worth of $426million. Ranking in at number 24, the couple owes most of their success to Ms Sepel's wellness blog and app, which paved the way for their vitamin empire JS Health. Clinical nutritionist Jessica Sepel, 32, (pictured) debuted at no. 24 on the Financial Review Young Rich List with husband Dean Steingold From working at Priceline after school, Ms Sepel's business is now the second most popular vitamin brand stocked in Australian pharmacies, despite only launching two-years-ago. The company's roaring success sees JS Health sell a bottle of vitamins every ten seconds, with plans to expand overseas in the UK, US and Asia. But it hasn't always been plain sailing for the entrepreneur, with several failed business ventures, including a healthy cereal brand, leaving the couple to lose out on tens of thousands of dollars. Ms Sepel and her co-founder husband Mr Steingold (pictured) have detailed their lengthy journey to success At one point, her husband Dean Steingold was forced to give her the blunt reality that it was time to let go of Ms Sepel's dream as the pair could no longer afford the risk. However, Mr Steingold told the Australian Financial Review sometimes you need to lose it all when launching into a business. 'You’ve got to lose every dollar. Then you’re ready to realise how hard it is to create anything,' he said. Refusing to give up, in 2018, Ms Sepel struck the big time with one of her ideas - developing a vitamin with an anti-stress and anti-anxiety formulation. 'I had patients with depression and anxiety, lacking energy, with poor sleep, and I would prescribe them high-dose fish oil, B vitamins, zinc and magnesium and suddenly, they would feel better,' Ms Sepel told The Australian Financial Review Magazine. 'I don't care if it's placebo or not … I saw results. I just knew I could make them better.' JS Health is now the second most stocked vitamin brand (pictured) in Australian pharmacies Ms Sepel says she was discouraged by some to continue on with her dream to break into the vitamin industry and that they were 'up against giants'. 'I don’t like the word haters, but there’s so many naysayers and doubters.' But with little money left and vitamin bottles costing approximately $20,000 for 2,000 bottles, the couple put everything into the business, and it proved to be a gamble that paid off.
