Vitamins for extra nutrition FAQs

Please visit our FAQ page for more detailed information.

How are they different from other vitamins?


The Fast 800 multivitamin has been designed to safeguard your nutritional requirements whilst following the Very Fast 800 with real food.

The vitamins included in the Multi-vitamin are based on a recent study conducted in Perth, WA, which found all participants were deficient in vitamin A, vitamin D, vitamin E, folic acid, potassium, zinc, calcium and magnesium.

The Fast 800 Multivitamin contains all of these essential nutrients, along with others that the Perth scientists didn’t test for, including selenium and iodine. People living in the UK have some of the highest rates of iodine deficiency in the world; iodine is vital for a healthy thyroid gland, which in turn helps control your metabolism. Iodine deficiency can lead to hypothyroidism (an underactive thyroid gland) which often leads to weight gain.

Please note, while we do recommend taking a high quality multivitamin when doing the programme, particularly on the 800 calorie plan, in order for extra nutritional support, particularly on fasting days, there is no necessity for this to be ours specifically – we wanted to simply provide this as an option.
