3. The PRO-TEEN® Formula Explained

What is PRO-TEEN®?

Intense bouts of exercise like gymnastics, combat sports, tennis, football, swimming and many more places a huge amount of stress on the developing athletes body.

As a result of the constant impact, sprints, jumps, rapidly changing direction and so on, a youth athletes body requires an instant batch of nutrients tailored to recovery, relative to their age.

Junior athletes have special dietary requirements during this period of rapid growth, where critical structural foundations are set to carry an athlete into adulthood. There isn’t a product on the market for our youth athletes to assist them in their recovery currently, so, we decided to solve this problem responsibly.

By researching unique nutritional needs of adolescent athletes and working backwards to design a food supplement product relevant for modern day academy athletes, we developed the perfect ‘all-in-one’ formula to kick-start their recovery process.

To perform like a pro, you have to refuel like one.

We designed our unique food supplement to be a high source of protein and combined great taste with a truly unique blend of isolate proteins (selected for bio-availability), into an equal carb ratio to be perfect for a youth athletes recovery & development after intense exercise.

Taste Sensation! Only the good stuff that supports performance and recovery goes in, and it tastes insanely good too!

Our winning formula is packed with nothing but good, essential nutrients tailor made to suit your individual needs, supporting youth athletes through advanced periods of growth.


3.1 Why did we design PRO-TEEN®?

Junior athletes have special dietary requirements during this period of rapid growth, where critical structural foundations are set to carry an athlete into adulthood.

Part of the reason for developing our range was because insights into the market show that teens in sport are already using mass-market supplements designed and marketed for adults, wrongly thinking that they are going to get quick ‘results’. These may contain elements unsafe for youths such as creatine or hormones. Marketing for most supplement companies along with media promotions also promote overly lean, muscular physiques, which is unethical and clearly unobtainable for teens.

The YSN team wanted to develop a lifestyle brand and product range that meets the values of our junior athletes to add real value - without the use of overly muscular bound athletes, or provocative imagery.

Teens in sport have to balance academic, social, high level sport alongside rapid periods of growth, meaning they may be at risk of dietary deficiencies if they have selective eating habits. PRO-TEEN® was designed to be a convenient alternative to counter selective eating or skipping meals, for occasions when no healthy food sources are available after training, or, as an alternative to fast or sugary foods/snacks.

As there is no product range on the market to cater for youth athletes, we set out to assist them in their recovery nutrition by developing an ‘all-in-one’ formula to kick-start a youth athletes recovery process and ensure selective eating habits, or restricted time schedules do not get in the way of recovery following intense exercise. We aim to support performance, development and recovery and confidence.

If youth athletes don’t tend to their diet, this may adversely affect health, development and ultimately performance / longevity in sport. Our overarching product aim is to eradicate common nutritional deficiencies and cater for additional nutrient needs, brought on by frequent participation in high-level sport.

YSN PRO-TEEN® is the first all-in-one shake for youth athletes, providing a convenient way to ensure recovery nutrition is catered for. It is designed to provide a convenient source essential nutrients in relative quantities, to facilitate the additional nutritional demands of participating at a higher level whilst still a developing athlete. 


3.2 How did we design PRO-TEEN®

The physical foundations of top level athletes are laid during adolescence, and we believe that we need to do all we can to support and lead our youths to become an outstanding generation of athletes, and this begins with adopting correct nutrition. 

The Applied Sports and Exercise Science team at YSN, along with fellow Life Science practitioners developed PRO-TEEN® by evaluating research from leading universities to identify common deficiencies and additional nutritional requirements of youths in high-level sport. We cross-referenced recommended intakes for age groups using all of our information gathered to estimate and carefully include selected nutrients into relative amounts based on age group categories set by the British Nutritional Foundation and other leading health authorities. Over the course of 2 years we worked to devise a bespoke formula that caters to the unique and advanced needs of a developing athlete. 

Our unique blend is designed to ensure any additional macro and micronutrient requirements are met, so that the risk of specific dietary deficiencies are reduced. This is in order to optimise performance and support normal development, where participation in high level sport may alternatively negatively affect this if a youth athletes diet isn't catered for.


3.3. Why choose PRO-TEEN®?

At YSN, we want to fuel you all the way to the top. PRO-TEEN® is designed to double up as your ultimate training partner, providing a convenient source of essential nutrients in the relative quantities to facilitate the additional nutritional demands of participating at a higher level whilst still a developing athlete. 

By supporting a young athlete's diet with a convenient source of essential nutrients, coupled with the correct nutritional guidance, strength conditioning and training regime, we aim to help eliminate obstacles to better health and nutrition and thereby help athletes push their limits and reach their full potential by guiding athletes to become more robust, better able to withstand the rigours of training and competition.

It maintains our position that dietary education and recommendations for developing athletes should reinforce eating for long term health and to moderate eating patterns to reflect daily exercise demands, providing a regular spread of high quality carbohydrates and protein sources over the day but especially in the immediate period after training. 

3.3. What are the Key benefits? 

Tiredness & Fatigue - Magnesium, Niacin, Pantothenic acid, Riboflavin, Vitamin B6, Vitamin B12 and Vitamin C contribute to the reduction of tiredness and fatigue

Immune System - Vitamin C contributes to the normal function of the immune system

Bone Builder - Vitamin D, Calcium and Phosphorus are needed for the normal growth and development of bone in children.

Our rockstar Vitamin D is sourced from cholecalciferol (pronounced: KOE-le-kal-SIF-er-ol) the most biologically active form of vitamin D found in humans and animals!

Memory & Concentration - Zinc and Iron contribute to normal cognitive function - This can be essential for youth athletes after training to concentrate and give 100% at college/school!

Protein - Protein contributes to growth & maintenance of muscle. 

Iron -  Iron is also critical for junior female athletes and a common deficiency within this community. We want to eliminate any risk of Anaemia, so PRO-TEEN® is designed to meet up to 84% of an adults RI*.

Carbohydrates -  Your body needs to replenish its glycogen stores immediately after exercise. Consuming carbohydrates with protein may also support absorption and uptake. This beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4 g per kg body weight, at doses, within the first 4 hours and no later than 6 hours, following highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. 

*RI = (Reference Intake) per 50g serving. (*RI = Reference Intake of an average adult (8400 kJ/2000 kcal).


3.4 Macros - Carbohydrates to Protein Ratio Split

PRO-TEEN® is designed as a bespoke food supplement geared up to support health and normal development after intense exercise. It contains a precision 1:1 ratio of carbohydrates to protein, which aims to help provide an excellent nutrient ratio for any athlete looking for replenishment after exercise.

After intense exercise, a healthy dose of protein will provide a rapid delivery of amino acids to your muscles to help support development and repair, optimising recovery time post training / match day. Protein may help repair, maintain and develop muscle tissue broken down in training, to reduce injury susceptibility and encourage normal growth.

With very low sugar, no preservatives, and all natural flavourings, our food supplement designed for youth athletes is second to none.


3.5 Carbs: Gluten Free Oatflower and More

Part of the carbs in PRO-TEEN® are from ultra-fine powdered oats. Oats have been shown to have a low glycemic index (GI); GI refers to the speed after which we ingest a carb source to the resulting rise in blood sugar and, hence, energy levels.

The oats in PRO-TEEN® mix easily and help sustain energy levels until the next meal. We also use maltodextrin as fast release carb source. Maltodextrin is a polysaccharide that is easily digestible and easy to mix, so there’s a valid reason for its use. However, although it’s a ‘complex’ carb, it actually has a high GI, so these formulas should work together to help replenish energy after training.

The gluten free oat powder in PRO-TEEN® has been milled so finely that it’s readily soluble, Plus, as oats are natural, they provide so much more than just carbohydrates: many vitamins, minerals, antioxidants and phytonutrients too.


3.5 Fats: Flaxseed, MCT's and More

The fats in PRO-TEEN® provide a significant part of the total energy and are made up from flaxseeds to ensure that the essential fatty acids are included in optimum amounts. We’ve also included MCT powder (found in coconuts) for very good reasons: the fats in coconut are what are known as medium-chain triglycerides, or MCTs, and these are treated much like carbs, i.e. they provide an energy-rich, sustained fuel. They may be perfect for athletes with intense training schedules. But MCTs have another invaluable quality: they are not susceptible to oxidation and rancidity, meaning that they do not contribute to the formation of atherosclerotic plaques which increase the risk of cardiovascular disease. In short, MCTs from coconut are a healthy and efficient source of energy.



The seeds of the Flax (or Linseed) plant have been used throughout history as a source of fibre and fatty acids, containing both soluble and insoluble fibre. It is free of added sugars, soy, dairy, fillers, flavours, and preservatives and is cold milled to ensure the powder isn't damaged during the production process.

There are two completely essential fatty acids (EFAs) that humans require: linoleic acid (LA – an omega-6 fatty acid) and alpha-linolenic acid (ALA – an omega-3).

Using our double blend of flaxseed and MCT's, we’ve ensured  PRO-TEEN® contains sufficient amounts of both of these EFAs as well as other omega-3 and -6 fatty acids. Moreover, these natural seed powders provide antioxidants and other vitamins and minerals in a biochemical redox balance to help minimise free-radical production. Free radicals may be involved in the pathology of cancer, cardiovascular disease and ageing, so it’s desirable to keep their formation to a minimum, and this is the role of antioxidants.


 3.6 Why does PRO-TEEN® contain Protein

Protein contributes to the growth and maintenance of muscle mass. Protein is also needed for normal growth and development of bones in young athletes. With up to 21g protein per scoop, this amount is formulated using a unique blend of healthy pea isolate proteins and fast acting premium whey isolates!

While whey protein concentrate has a protein content of around 80%, the protein content of whey protein isolate is more like 90%. This is because whey protein isolate undergoes a process called Cross-Flow Micro-filtration. This separates the protein from fat, cholesterol and lactose meaning a purer protein as the end product.

Whey protein isolate is believed to have less fat, cholesterol, lactose, carbohydrates and calories than most other proteins on the market, making it a common choice for those looking to maintain low levels of body fat but who still require the protein to help their muscles repair and recover.

Whey protein isolate has a higher protein content and is lower in carbohydrates, lactose and fat. But it is typically more expensive due to the additional manufacturing process it undergoes. They are more rapidly absorbed than concentrates and create a more profound insulin response, making whey isolates popular post-workout choices. 

Are Whey Isolate Proteins Lactose Free?

Although whey protein concentrate is already considered low in lactose, whey protein isolate is considered even lower because of the additional manufacturing processes. Whey protein isolate is therefore often recommended for athletes who suffer from lactose intolerance.

If you are lactose-intolerant and do choose to drink whey protein shakes, use only isolate powder and avoid whey concentrates or powders that are made from a mix of isolate and concentrate.

As whey concentrate and isolates go through a process to remove most of the carbs, fat and lactose from "regular unprocessed whey" from whole milk. This process is called "ion exchange" or "filtering." Both result in an almost pure protein. A "concentrate" is 80% protein and an "isolate" is typically 90% protein.

For YSN® customers, PRO-TEEN® contains a unique blend of Whey and Pea Isolate Proteins, meaning it may be a better choice if you are lactose intolerant (but it is always advised to check with a registered health official first). Our blend features a very high protein purity and gets the best of both animal and plant based products, without compromising taste, texture or quality.


4. Vitamin and Minerals in PRO-TEEN®

A bulk of the vitamins and minerals – also known as micronutrients – in PRO-TEEN® are from natural ingredients. All of the vitamins and minerals found in our blend are specifically chosen for a select reason and are contained in relative quantities to your age and stage of growth development. These are based on sub population food groups based from the British Nutritional Foundation.

Note: As upper safe limits for vitamins and minerals in children and adolescents are still to be evaluated, we advise that athletes do not exceed daily recommended intakes. 

5. Amino Acid Profile of PRO-TEEN®

Amino acids are the building blocks of protein within the body and are involved in the transport and storage of nutrients.

The 20 amino acids that exist can be divided into essential and non-essential, which determines whether they can be produced within the body or not. The body can produce 11 amino acids, and therefore these are termed non-essential, whilst the remaining 9 (essential) must be consumed through the diet. All 20 amino acids are required for the human body to function healthily, with their roles including, but not limited to the production of:

  • Proteins
  • Muscle
  • Cells
  • Hormones
  • Enzymes (allow reactions to happen)
  • Energy

Amino Acid Content of PRO-TEEN™ (All Flavours)

Essential Amino Acids 

Per 50g Serving

Per 100g

























Non-Essential Amino Acids










Aspartic Acid






Glutamic Acid
















Every scoop of PRO-TEEN® contains a 4:1:1 ratio of Leucine to Isoleucine and Valine (Essential Amino Acids). These amino acids are considered essential as they are not produced by the body so must be obtained through your diet.

All protein sources are not equal: some are classed as ‘complete proteins’ and some are not. A complete protein is one that contains sufficient quantities of all nine essential amino acids.

Generally, proteins derived from animal foods (meats, fish, poultry, milk and eggs) are complete. Indeed, some proteins derived from plant foods (legumes, seeds, grains and vegetables) are often complete as well; examples include chickpeas, black beans, pumpkin seeds, cashews, cauliflower, quinoa, pistachios, turnip greens, black-eyed peas and soya. Many plant foods have insufficient amounts or one or more of the essential amino acids. 

The protein in PRO-TEEN® comes from three of the main ingredients: pea & whey isolate protein, oats and flaxseed. This ensures a good range of all amino acids and that there are sufficient amounts of the essential amino acids. Pea protein is low in cysteine and methionine but high in lysine. This is why we selected this source, ensuring everything was covered whilst keeping PRO-TEEN® low lactose. Plus there’s additional protein from the oats, which are reasonably high in all essential aminos, and the flaxseeds.


6. Is PRO-TEEN® for Me?

If you are a youth athlete and struggle with getting the right foods in, participate in intense exercise and are looking for an ‘all-in-one’ recovery product, then PRO-TEEN® may be the textbook choice.

This product is also tailored to help you meet your individual daily macro and micronutrient requirements for the day, where selective eating or busy schedules/traveling may otherwise compromise intake.

Please note - If you are unsure as to whether or not you or athlete requires PRO-TEEN®, then we recommend consulting a qualified health practitioner first. YSN have taken every care to ensure our range is suitable for consumption, and take no responsibility for incorrect or over-usage.


6.1 Amounts of PRO-TEEN® for different age groups

 As upper safe limits for vitamins and minerals in children haven’t been evaluated, we suggest youth athletes consume PRO-TEEN® up to around the recommended requirement levels for their age which is a maximum of 1 scoop per day after intense exercise or as a meal replacement on low activity days. The following will give you a guide as to how much PRO-TEEN® a youth athlete can include as part of a varied diet, whilst encouraging them to eat good wholesome foods every day. If your teen has health issues, we recommend you consult your doctor or relevant clinical professional before allowing them to consume PRO-TEEN®.

Please note the below values are present as guidelines only, and that is important that youth athletes do not exceed the stated daily recommended amounts.

Children Under 4
PRO-TEEN® is not suitable for babies or infants below or during weaning age. Parents of children under 4 years old should consult their doctor or relevant health care professional before allowing their child to consume PRO-TEEN®.

4- to 6-Year-Olds

We always advocate a food first approach for younger participants. The aim here being to set nutritional foundations for life, but we understand selective eating can sometime be an issue. Only if necessary, Children of 4 to 6 years of age may include up to ¼ of a scoop (about 12.5g) PRO-TEEN® per day. This is around one quarter of their daily nutrient requirements and can be a great recovery snack to ensure your child is getting a range of vitamins and minerals in after sport. Always consult a qualified medical practitioner first if you are unsure about introducing PRO-TEEN® into their diet.

7- to 10-Year-Olds
7- to 10-year-olds can enjoy ½ a scoop (about 25g) of PRO-TEEN® per day, which would help them meet their daily nutrition needs to counter selective eating habits. PRO-TEEN® is ideal for fussy kids who won’t eat enough fruit and veg to support high levels of participation in sport. Again, athletes within this age group should be encouraged to meet their daily recommended intake via whole foods first.

11- to 13-Year-Olds
Young adolescents can include around ¾ of 1 scoop (about 37.5g) of PRO-TEEN® a day. At this growth spurt age, energy requirements are high, especially in active athletic kids; PRO-TEEN® provides a good contribution of protein, energy and vitamins for this age group.

13- to 18+-Year-Olds
Older adolescents have, in most cases, nutritional requirements greater than those of adults due to the fact that they’re growing, they’re often as physically active as professional athletes and have to balance this against studying at school or college. This age group can enjoy 1 full scoop of PRO-TEEN® (50g) freely as part of a balanced, varied diet after intense sport or on low activity days.


6.2 When Should I Consume PRO-TEEN®?

To reap the benefits of this product, we recommend consuming this product immediately post-exercise with water or milk where whole foods aren't available.

Top tip: PRO-TEEN® can be easily consumed whilst your coach is doing their post-match team talk or as you’re leaving the gym changing rooms for instance, just remember to pay attention! 


6.3 Suggested Use

Add 1 level scoop (50g) to 500ml of water or milk in a YSN® Zen Shaker and consume within 30 minutes post-session.

Alternatively, consume in the mornings with smoothies, porridges, Greek yoghurts, pancakes or on its own on low activity / rest days.

Store in a cool, dry place away from direct sunlight. This product is intended to be used alongside an active lifestyle and a balanced diet. Suitable for vegetarians.


Serving Size - 1 level scoop (50g). (Scoop provided but may settle toward the bottom of pouch during transit).

Servings Per Container - 20 (1kg)
