Backed by nutritonists:

As a mum to a sporty teenage daughter and registered nutritionist, I understand the need for quality sport nutrition and clear education for youth sport. 

YSN products have been formulated with great care and backed up by science to support their specific life stages nutrient needs. This ensures that young athletes needs are fully addressed. 

Whether it is through the occasional nutrient top up, convenient post workout shake, or as a regular dietary addition - YSN is really setting the standard to support our future sports stars.

YSN products offer youth athletes a convenient way of ingesting the right nutrients at the right time.

YSN NUTRI-TEEN Shakes allow young athletes who can't find time to eat, or struggle with appetite to obtain the essential macro and micro nutrients in just one shake. The new NUTRI-TEEN Shake adds flexibility to the product range by catering for vegetarian/vegan athletes.

The NUTRI-TEEN Oat Energy bars offer youth athletes with a nutritious snack option that will help to optimise their fuelling before and/or during training.
