Science and Research behind our Product development

We spent months of research working with a team of leading Applied Sports and Exercise Scientists and Nutritional experts. 

We invest our resources in Science, R&D - That's why our product formulation is underpinned by:

  • Scientific evidence of the nutritional needs of youth
  • Identifying key macro/micro-nutrients essential for a youth
  • How each of these nutrients correlate with each other for maximum effect
  • How these nutrients are absorbed in their body
  • How the ingredients will support the gut microbiome stability of a young person


Working with Sports & Exercise Scientists and Nutritional Experts - we used sports science, food science & nutrient synergies to create our recipes to support the diverse needs of young people which is different to adults, to optimise nutrient absorption and performance. Long term impact of health benefits is our priority and that's why we invest our resources in science backed research.


We carefully chose our Macro & Micro nutrients (protein, carbs , good fats, vital vitamins & minerals) essential for optimising performance. Carbohydrates support energy, Proteins for muscle synthesis, Magnesium for bones & electrolyte balance, Vitamin B12 for healthy oxygen flow, brain & immune function, Copper for minimising oxidative stress caused by exercise, Manganese, Phosphorus, Potassium for energy metabolism.


We are proud to have worked with academia experts who are gut-brain researchers.

Gut is one of the most active part of the human body with over 70% immune cells in our gut. Further human colon harbours about 10 micro-organisms and over 1000 species of bacteria and is considered the most metabolically active site in the human body. . These intestinal microbiota have been shown to play a prominent role in maintaining gut health.

ProYouth Bars contain ingredients that not protect and improve the gut microbiome stability of the athlete but also aids effective nutrient absorption.

Nutrition Experts Quotes

The ingredients in ProYouth bar target gut microbiome stability, an imperative additional benefit for this age group as their gut microbiome is still developing and a stable and diverse microbiota ensures their ability to absorb nutrients, manage the sustained psychological stress involved in competitive sports, and prevent adult onset non-communicable diseases.

Young athletes train incredibly hard and are at increased risk of overuse injuries. The harder we train the more we stress our cells and tissues. Repetitive training can cause molecular changes and micro-tears to the muscles and tendons resulting in pain, inflammation and repetitive strain injuries such as tendonitis, due to the constant pressure exerted on the muscle repetitively.

To prevent these  types injuries the right nutrition should be used as a tool to recover and repair our bodies as athletes. Protein, carbohydrates and essential fats paired with the right vitamins and minerals are vital for the body’s recovery process and normal functioning.
