Why Bioteen Created This Supplement

Gaining lean bodyweight is often a challenge for teenagers as their bodies demand more energy and nutrients for exercise and growth. This can be true for teenagers who are below the average weight and size for their age as well as athletes looking to improve their strength, size and performance on the sports field.  The solution is the same for both groups, choosing the right exercise and the right diet and nutrition.

What Is Lean Muscle Builder & Who Should Be Taking It

Lean Muscle Builder is a unique blend of premium protein and carbohydrates designed to support a teen’s natural ability to develop muscle mass through exercising and the right diet.

Lean Muscle Builder is well suited for Teenagers who identify as skinny or teen athletes looking to add lean muscle to improve the strength, agility and speed. 

Bioteen’s Lean Muscle Builder has been formulated for teenagers who are looking to:

  • Add lean muscle
  • Enhance their strength & physical presence
  • Improve their performance in their sport

The Science (How Lean Muscle Builder Works)

You don’t need to be a body builder to add lean muscle.  Anyone is able to add lean muscle, by simply understanding the science about how the body builds muscle and following the correct diet and exercise plan.

When we do the right kind of exercise, our muscle fibres experience microscopic damage which the body repairs.  Regularly doing the right type of exercising creates a cycle of damage and repair which makes muscles bigger and stronger over time.

Muscles rely on more than just exercise to grow.  Without the right nutrition and rest your body will never be able to repair damaged muscles fibres.  Protein in our diet preserves muscle mass by providing the building blocks for new tissue in the form of amino acids. Protein intake, along with the naturally occurring hormones in your body, help shift the body into a state where muscle tissue is repaired and grown.

The body responds to the demands you place on it.  If you do the right exercise regularly, eat right, rest and repeat this cycle, you create the conditions to make your muscles bigger and stronger.

Bioteen’s Lean Muscle Builder has been formulated to give you the necessary nutrition you need to support your objective of adding lean muscle by giving you the following key ingredients.

Native whey protein is an excellent source of protein with a full spectrum of branch chain amino acids which are the building blocks your muscles need to repair themselves. Our bodies do not produce protein naturally, so we need to get this from our diets.  Eating adequate amounts of protein helps maintain muscle mass and promotes muscle growth when combined with strength training.

Numerous studies show that eating plenty of protein can help increase muscle mass and strength.

Carbohydrates stimulate insulin which increases protein synthesis, reduces cortisol and slows protein breakdown. Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4g 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.

Bioteen’s LMB contains three different GMO -Free plant- based carbohydrates.


Derived from maize, maltodextrin digests and absorbs rapidly, is easy on the stomach and supplies glucose to replenish muscle glycogen.


Derived from white beet, PalatinoseTM digests slowly to supply constant energy, preventing energy crashes.  PalatinoseTM has a minor influence on the blood glucose level and a low insulin index. Insulin plays an important role in the absorption of nutrients by our muscles and it contributes to a better energy supply and muscular tissue growth.

Waxy Maize Starch:

Derived from maize, Waxy Maize Starch is a fast -acting, slow digesting carbohydrate which is 100% sugar and lactose free.  Unlike other high glycaemic index carbohydrates (like dextrose) that cause insulin levels to rise which in turn make your body more prone to storing fat, researchers have found that Waxy Maize Starch doesn’t spike blood sugar levels and insulin levels as much, making it a preferred choice carbohydrate for athletes who want to keep body fat levels low but at the same time increase muscle mass, since you effectively get all the recovery benefits without the added insulin and fat storage.

A natural fibre that promotes healthy gut bacteria for improved digestion, immune function and overall health.

Lean Muscle Builder “LMB” contains 12 vitamins and minerals that contribute to overall health and wellness. Vitamin B6 which contributes to the metabolism of dietary proteins and micronutrients such as Zinc and Magnesium to support muscle protein synthesis that contributes to energy release and supports muscle function during exercise.

Ingredient Transparency & Quality (Not All Ingredients Are Created Equally)

Bioteen showcases a relentless commitment to a superior quality product that is both ethical and safe for consumption in the extremely important phase of the lives of teens.

Ingredient quality is a core focus for us at Bioteen because better ingredients yield products that are highly effective and safe. That’s why Bioteen has set the bar high when it comes to the evaluation of our ingredients, from how different forms of ingredients work in the body to where they are sourced and how they have been manufactured. Bioteen has partnered with international suppliers who share our beliefs for quality, purity and scientific research.

  • Ingredient safety: All ingredients used in Bioteen are GRAS certified (Generally Recognised as Safe) as published by the Food and Drug Administration (FDA).
  • Scientifically Researched: we only use ingredients that have been tested in scientific studies to be safe and effective for their intended purpose. 
  • Allergen control: Bioteen products have been formulated with a careful consideration for consumers with specific allergies and sensitivities.
  • Branded ingredients: our key active ingredients are all branded, i.e. trademarked-protected, ingredients. Branded ingredients are manufactured to higher quality standards than generic products and offer higher levels of purity, transparency in their manufacturing as well as clinical research supporting their efficacy. Branded ingredients often provide scientific and educational support that makes it easy for a consumer to learn more about the science behind the specific ingredient used in the making of Bioteen products.

At Bioteen, we have a commitment to quality throughout our entire manufacturing process. Because we source all our raw materials ourselves, we have total control over what goes into Bioteen products. Our manufacturing is then undertaken by carefully selected contract manufacturers who are third-party certified.

Good Manufacturing Practice (CGMP) certification: CGMP refers to the Current Good Manufacturing Practice regulations enforced by the Food and Drug Administration “FDA”. is a system for ensuring that products are consistently produced and controlled according to quality standards. It is designed to minimize the risks involved in any pharmaceutical production that cannot be eliminated through testing the final product. The cGMP acronym originated in the USA, where the US food and Drug Administration wanted to impress upon manufacturers the importance and need for “continuous” improvement to their approach to product quality.

Quality Manufacturing Stamp

Everything that goes into our product is thoroughly tested and sampled by our food scientist and owner. We know and understand the importance of everything that goes into our products and what functionality it serves to the teenage body, scientifically testing every ingredient to ensure a safe and ethical product.

This testing and lab sampling has led us to where we are today (and trust us, there have been some interesting and awful concoctions that we have come up with), a superior quality and excellent tasting product that allows teenagers, with Bioteen, to own the whole day to support their diet. From breakfast to dinner, Bioteen’s product range is a vehicle for delivery for vitamins, minerals, stress minerals, prebiotics and whole food nutrition and other things that teens need.

The answer is quality. Let’s face it. Musclebuilding shakes have gotten a bad rap, and rightfully so. Too often, these products contain an overabundance of carbohydrates, especially of the fast-releasing kind as well as lower-quality sources of protein. They can cause weight gain rather than lean musclebuilding that you’re after. This product is called a “Lean” Muscle Builder, and not “Bulk weight gainer” for a good reason. That’s because it is designed with a specific ratio of high- quality proteins to carbohydrates to fuel muscle cells, rather than fat cells.

The sweet spot for building muscle is approximately ages 15 – 25 when both the testosterone and the growth hormone levels are high. Please note that puberty comes at different ages for different people so the age 15 is an approximation. A much more accurate start of the prime muscle building era is when you develop armpit and facial hair.

We don’t recommend completely replacing solid meals with shakes but if for some reason you can’t eat a meal or don’t have the time, then you can use a serving of Lean Muscle Builder. It is always best to get in the calories you need than to go for a long time without eating, especially when you’re trying to build lean muscle.

No, Lean Muscle Gainer contains whey protein concentrate which contains lactose.

Lean Muscle Builder has been designed to taste great with any choice of liquid. Dairy milk is a great choice to aid in consuming additional calories.

Bioteen Lean Muscle Builder contains whey protein. Whey protein is an ideal protein choice for musclebuilding because it has the highest biological value among all supplemental protein sources. This means that it is well utilized by the body for growth of body tissues. Whey Protein is also rich in Leucine which acts as a trigger of protein synthesis in muscle.

Research suggests that consuming lean protein 15 – 20 minutes before, during and within one hour of working out may improve muscle gain. Since you are probably not going to be eating a steak or chicken breast at gym, a protein drink or supplement may be beneficial immediately before, during or after workouts, but it is not necessary.

Protein needs are based on age, sex, body weight and stage of development, with Teenagers needing between 10 to 30% of their daily calories from protein. Although an individual’s exact needs will vary, the Recommended Dietary Allowance (RDA) provides a good reference for how much of a certain nutrient a healthy individual needs in a day. The RDA for protein is 46 grams for Teenager girls and 52 grams for Teenager boys per day.

The amount of protein Teenagers needs depends on their height, weight, gender and level of activity. More active Teenager Athletes require more protein than the recommended RDA.

Bioteen Lean Muscle Builder contains dairy-based Whey Protein, making it suitable for vegetarians but not vegans.

Gaining lean muscle is often a challenge for teenagers as their bodies demand more energy and nutrients for exercise and growth. This can be true for teenagers who are below the average weight and size for their age. The solution is choosing the right exercise programmes and the right diet and nutrition.
