And other delicacies.
Successful applicants will chow down on things such as white bread, eggs, pasta, chicken and rice for a month, while also taking their vitamins.
Participants will have their vitamin levels tested before and after they spend a month trying out the diet alongside the one-a-day vitamin to see they’re any healthier.
Feel co-founder Boris Hodakel said: “We in no way want to encourage people to use our multivitamin as a substitute for a healthy diet, the purpose of this study is to test the effectiveness of our product, outside of a lab or controlled environment, where results don’t reflect reality.
“We want average members of the public to eat a version of the modern Western diet – under the watchful eye of a doctor and nutritionist, to see whether Feel is as good as we think it is, in the real world.”
Applicants need to be over 18 years old, and can’t have any underlying health conditions or be undergoing any form of medical treatment – as well as confirming you’re not allergic to any of the ingredients in the product.
