Bioteen's Biolean is a low carb, high protein ready-to-drink shake that provides essential amino acids for the body to repair and maintain lean muscle tissue. It consists of a combination of fibre, fat, vitamins and macronutrients to delay post-meal hunger and reduce appetite between meals whilst supporting blood sugar levels.
Clean Formula


Fast Fact

Studies have shown that Fibersol®-2 AG can provide an increased feeling of satiety, leaving consumers feeling fuller for longer periods of time.

Fast Fact

Protein is essential for blood sugar control. It helps slow digestion and prevents post-meal blood sugar spikes, as well as increases feelings of fullness. Plus, it may help prevent overeating and promote excess body fat loss, two effects that are essential for healthy blood sugar levels.

Fast Fact

Palatinose is a fully digestible, sustained-release, disaccharide-type carbohydrate derived from sugar beet.   Palatinose’s sustained-release formulation allows it to provide a steady supply of carbohydrate energy with less effect on blood glucose levels and insulin.

Fast Fact

Stable blood sugar means your cells don’t get flooded with insulin, which in turn gives your body time to burn fat for energy in between meals.


Whey Protein

Whey Protein Concentrate

Muscle Repair

The Whey Protien used by Bioteen in our products is a native whey protein concentrate made from whole milk that is free from antibiotics and hormones (rBHG).


Whey Protein is a high quality dairy protein source that helps increase protein intake. A higher protein intake increases levels of the satiety (appetite-reducing) hormones GLP-1, peptide YY and cholecystokinin, while reducing your levels of the hunger hormone ghrelin. Intake of protein may reduce cravings and snacking as well as increase energy expenditure during its digestion which requires a high energetic input compared to carbohydrates and fats.   


Protein is also essential for muscle maintenance and to avoid the body utilising the body’s muscle as a source of energy. 




Sustained Energy

Palatinose™ is a source of glucose and fructose to the body. Unlike other sugars, Palatinose™ digests and absorbs slowly thus providing the body with a steady supply of energy.   Using Palatinose™ instead of sucrose supports blood sugar management and steers the metabolism towards fat burning by promoting the utilisation of body fat as an energy source. Palatinose™ is therefore the only carbohydrate to provide a sustained supply of energy in form of glucose, while at the same time supporting fat mobilization.


Fibersol 2

Prebiotic Fiber

Satiety & Fullness

Fibersol®, a soluble prebiotic dietary fiber, may impact satiety by decreasing hunger, prolonging satiation or increasing satiety signals from the gut. Recent studies have shown that Fibersol can provide an increased feeling of satiety, leaving consumers feeling fuller for longer periods of time.


Prebiotics like Fibersol-2 are also a vital source of ‘food’ for the gut bacteria. This helps them to produce beneficial substances like short-chain fatty acids, which strengthen the physical gut barrier and regulate the immune response.

A healthy gut also ensures that nutrients are properly absorbed.



Chelated Minerals

Energy Support

Bioteen’s Biolean contains  a blend of 8 highly bioavailable chelated minerals consisting of Magnesium, Zinc, Selenium, Iron, Copper, Chromium, Molybdenum and Boron. These minerals play essential roles like assisting with protein synthesis, antioxidant support, maintaining normal muscle and immune function, assisting normal carbohydrate metabolism and the reduction of tiredness and fatigue.



Chromium Chelate

Apetite Regulation

Chromium is a trace mineral that facilitates the action of insulin, thus helping in the regulation of blood sugar levels. Improper blood sugar regulation has a big impact on hunger and appetite as blood sugar level dips can make a person end up feeling hungrier and eating more.


Supplementation with Chromium may decrease food craving and intake.


Go Fat

Coconut MCT's

Energy Satiety

GoFAT Coconut is a coconut oil powder that provides a special form of fat called Medium Chain Triglycerides (MCTs). Due to their shorter length, MCTs are more easily digested than longer-chain fatty acids found in many other foods and are thus an immediate source of energy for the body.


MCTs  promote satiety (a full feeling post consumption) as well as supporing the maintenance of blood sugar levels.




Immune Support

L-glutamine is the most plentiful amino acid in the body. It’s involved in protein synthesis and serves as fuel for the immune system. L-Glutamine has also been recommended to support the reduction of sugar cravings via it’s affect on insulin levels. 



Multvitamin Blend

Energy Vitality

Teen Vitamin Premix (TVP) is a blend of 12 highly bioavailable vitamins, consisting of Vitamin A, D3, B1, B2, B3, B5, B6, B12, C, Folic Acid and Biotin. These vitamins are involved in key functions that relate to health and muscle development like energy-yielding metabolism, protein metabolism, protein synthesis, red blood cell production and the reduction of tiredness and fatigue.

If you’ve ever gone a little too long between meals, you will know the term ‘hangry’ full and well. When the body doesn’t get the fuel (aka glucose) it needs from the food you eat it uses up almost all of the glucose in your blood (aka blood sugar). Although in a healthy person, this won’t technically result in a low blood sugar because your body is a finely tuned machine, when your blood sugar levels go lower than their usual level you can start to feel low blood sugar symptoms like hunger, irritability, and loss of concentration.


Some teens are pretty busy and between school, sports and social activities, they may find themselves between meals with nothing to snack on. That’s where Bioteen’s Biolean comes in. A very handy snack replacement to help maintain your teen’s blood sugar levels even when they are on the run.


Let’s have a look at how the ingredients in Bioteen’s Biolean work together to maintain your teen’s blood sugar levels.


Manages blood sugar levels

There are two main factors that influence how quickly (or slowly) the carbs we eat enter our bloodstream. In general, you want a slow and steady release instead of a huge spike (which may be followed by a dip).


The first is the glycemic index (or GI) of the food. Basically, the GI is how quickly a food is absorbed, the lower the GI, the slower it will be absorbed. This rate is affected by the type of carbohydrate as well as the other components of the food. Carbohydrates that are more difficult to break down, like long chain polysaccharides have a lower GI whereas short chain sugars like glucose or fructose are absorbed quite quickly and thus have a higher GI. In addition to this, if a food is higher in fiber, it will also be absorbed more slowly. For example, a slice of whole wheat seeded loaf will be absorbed slower than soda (even if the amount of carbohydrates in each serving is the same). We have included Palatinose® in Biolean for this very reason. It’s known as a smart carbohydrate because of its unique composition where enzymes have been used to rearrange the linking bonds of beet sugar, making it a low GI food (GI<55) (1). In fact, it takes about 4 to 5 times longer for the enzymes to split isomaltulose in comparison with sucrose.


Secondly, the composition of the food can affect how quickly the stomach empties (known as gastric emptying). This means that the food passes more slowly into the small intestine, so the body is getting a smaller amount of energy more consistently. The nutrients that delay gastric emptying include protein (like native whey protein), fiber (like Fibersol-2®) and fats (like GoFat MCT oil).


Balanced blood sugar means better moods!

Not only is sustained energy important for active teens, but for general well-being because sugar dips can affect concentration and mood. The average teen’s brain can use up to 120g of glucose per day, which is about 30% higher than the amount an adult needs (3). Due to this higher rate of glucose metabolism, teens may be at a higher risk of the negative impacts of blood sugar dips (4) and so having a constant supply is crucial (1). In order to have this constant supply, we need to focus on foods that have a slow and steady release of glucose (aka low GI/ glycemic index choices). That’s why Palatinose™ is ideal, it provides a stable supply of glucose which is still completely absorbed, meaning it gives as much energy as other carbohydrate sources. Slow release carbs have been associated with an improved mood (because your teen isn’t feeling hangry)(4) as well as improved concentration and memory (5,6).


Helps the body to tap into energy reserves

Because of the way that Palatinose® is digested and absorbed (slow and steady with low insulin release), the body is also able to tap into fat stores if necessary (2). Most people have a good-sized energy reserve stored as fat and so if we can safely tap into them, refueling more frequently may not be necessary.


Fat and fiber keep you feeling fuller for longer! 

Not only does delayed gastric emptying (from a meal containing fat and fiber) help to manage your blood sugar levels, but it also helps to keep you feeling fuller for longer. You’ve got important things to do and being hungry the whole time isn’t ideal. Some research even suggests that medium-chain triglycerides (MCT) may be more satiating than consuming long-chain triglycerides (which are the fats commonly found in most fatty foods) (3). This is another reason why GoFat MCT oil was our go to for this product. To add to all of this, fiber, in the form of Fibersol-2® also appears to stimulate your satiety hormones which increases the fullness factor even more (4)!


Protein helps to develop, grow and repair cells

Protein is one of the most important macronutrients to consider during the teenage years because in its simplest form, as amino acids, it forms the building blocks for cell development, growth and repair (5). This goes for muscle cells, hormones (like testosterone and growth hormone), transport cells that move iron into the blood and even the antibodies of the immune system. We have included native whey protein in Biolean to make sure these increased needs are met.


Promotes gut health & immunity 

At Bioteen, we’re also committed to teens’ overall health and the ingredients that we include in our product reflects that. We love using ingredients that target more than one pathway. For example, the probiotic fiber found in Fibersol-2® is a great way to feed the microbiome (6). As the microbiome acts as a protective layer against pathogens as part of the physical gut barrier. In addition to this, when the microbiome is well fed, they produce beneficial substances called short chain fatty acids which further strengthen the epithelial layer (7). So having a diet rich in prebiotics is key to maintaining gut barrier function, which has a knock-on effect on protecting the body against infection (amongst many other things).


The bottom line

Bioteen has developed Biolean to be a balanced snack replacement for busy teens. No one likes to feel ‘hangry’ and this is the perfect all-in-one solution that contains everything you’d need in a snack, and more!
