I’m sure everyone who has worked out has heard of pre-workout and of its benefits. It’s great for getting you through those tough workouts on days when you don’t feel like it. However, the possible side effects must also be taken into account.

Does Pre-Workout Stunt Growth?

Most research shows that the ingredients in pre-workout do not stunt growth. Caffeine in pre-workout has shown to have other side effects to some. Most of the other ingredients found actually promote growth, rather than stunt it.

What Are The Ingredients In Pre-Workout?

Caffeine

Caffeine is the most popular drug in the world and is one of the main ingredients in a pre-workout. Caffeine anhydrous to be exact, which is the dehydrated version, which is very concentrated.

Studies have taken adolescents below the age of 18 and measured their bone growth after caffeine consumption and no correlation between caffeine use and bone growth was shown.

High amounts of caffeine have been shown to cause dizziness, insomnia, anxiety, and headaches. This is mainly to caffeine sensitive people and usually only happens when a high dose is taken. Caution should be used when taking caffeine. Stunted growth is not an included side effect of caffeine.

There are rumors that caffeine may cause osteoporosis which is a disease associated with loss of height. This is because caffeine can cause the body to remove calcium and lack of calcium can contribute to osteoporosis.

However, the effects of caffeine on calcium excretion is very little and the link between caffeine consumption and osteoporosis was never actually confirmed.

Beta-Alanine

Another ingredient found in pre-workouts. It is an amino acid that combines with histidine to make carnosine, which reduces lactic acid build up in the muscles. The less lactic acid in them, the less sore they will feel while you workout.

A few studies were done with 15 year olds and no effect on height was shown. Their gym performance was improved though. There’s no research to prove that beta-alanine has any effects on height.

Citrulline Malate

Another ingredient found in pre workout supplements. It is a non-essential amino acid which helps boost nitric oxide production. It also helps with nutrient absorption and bio availability, along with vasodilation.

Even in high doses, it hasn’t been shown to have any side effects. Plus, it is also found in watermelon, pumpkin, and cucumber. So it is safe and will not stunt growth.

Taurine

It is not found in all pre-workouts, but should be discussed. It is a naturally occurring amino acid in the body that uses protein to grow and repair tissues.

Lack of taurine in the body has more side effects than actually taking it does. This means that it is safe for consumption and studies show it will not lead to stunted growth.

Vitamin B12

Not even sure if this one is worth mentioning because it should be pretty obvious. However, it is worth going over just in case. Vitamin B12 only has benefits, it helps with proper nerve functioning and with producing red blood cells and DNA.

It is actually vital for growth and increasing height, so it will not stunt growth at all.

Artificial Sweeteners

Many artificial sweeteners such as Acesulfame K, sucralose, and saccharin are used inside pre-workouts. While artificial sweeteners are not considered to be healthy, there is no research that shows them having any effect on growth.

Are Pre-Workout Supplements Safe For Teens?

While pre-workout doesn’t seem to have any serious risks for teens, it still isn’t the best possible option for growing adolescents. Addiction and high doses are the danger. High doses of the ingredients in pre-workout aren’t healthy for anyone.

Plus your body will become dependent on the boost that you receive from it. A 16-year old doesn’t need to be dependent on a supplement to receive their energy. With a well-balanced, healthy diet, and hydration they should have all the energy they need. A coffee here and there or maybe taking pre-workout once a week will not hurt.

It’s important to note that caffeine is probably the most dangerous ingredient in pre-workouts. Mainly in high doses, but even low does can show negative effects for some people.

If you are going to take pre-workout supplements as a teen, make sure to choose a well researched brand with safe ingredients. Make sure to only take the recommended dose and not take it all the time. Don’t take any other caffeine while using pre-workout such as energy drinks.


If any serious caffeine side effects occur such as nausea, sever dehydration, insomnia occur you should stop use.

What Does Cause Stunted Growth?

Turner Syndrome

Turner Syndrome is a rare genetic condition that affects females missing an X chromosome. It causes the body to not use growth hormone properly resulting in stunted growth.

Genetics

Unfortunately if your parents are both shorter, you will most likely follow. Genetics cannot be changed.

Poor Nutrition

Here is something that you can prevent against. Children deficient in essential amino acids often experience stunted growth. It also causes children to have less energy and less interest for learning, which negatively affects cognitive development and academic performance.

Child maturation can result from both over nutrition and under nutrition as both are deficiency diseases caused by inadequate nutrition. Both of these affect growth rate, body weight, and height.

Growth Hormone Deficiency

Normal growth hormone levels allow the growth of tissue and bone, Those with a deficiency will have little to no growth hormone because their pituitary gland is unable to produce it. It is also known as dwarfism.

Takeaways

Other than poor nutrition, there doesn’t seem to be many other causes of stunted growth. Pre-workout has not shown to stunt growth in adolescents, but still has other side effects that should be considered. When used properly, pre-workout can be helpful for teens looking to improve their workout.

Most claims stating that pre-workout or caffeine stunts growth are myths with no scientific proof. As long as children are getting proper nutrition and enough sleep, there is no reason that pre-workout will affect their height.
