What is a multivitamin?

A multivitamin is a formulation containing a number of vitamins and minerals that our bodies need on a daily basis to function optimally.


What does a multivitamin do?

A multivitamin ensures that you meet your recommended daily allowances (RDAs) for a number of vitamins and minerals. As active individuals, nutritional needs are often higher than for those who are less active, which can make it difficult to obtain the required levels from diet alone. Taking a multivitamin, alongside a balance diet, can ensure that you are meeting your daily requirements for health and performance.


What makes this multivitamin different?

The Science in Sport Multivitamin is a premium formulation designed to meet 100% of the recommended daily allowance for 19 vitamins and minerals. Lower quality multivitamins often under-dose or mega-dose nutrients, with potential harmful effects on athlete health. This formulation has been designed specifically for the requirements of endurace athletes, which are different for those not involved in regular excercise.


When should I take Performance Multivitamin?

Consume 1 tablet per day alongside food.


Is it Informed Sport tested?

Yes, as per all of our products, Science in Sport Performance Multivitamin is tested under the Informed Sport programme.
