Energy Drinks
Many people rely on some type of energy boost to get them through the day. That might be a cup or two of coffee, a sugary caffeine-filled pop or the popular energy drink. Energy drinks are a huge business. The worldwide energy drink market is expected to reach $61 billion in 2021. Over the last 10 years, energy drinks has become a close second to coffee when it comes to getting your hit of energy. At the beginning of the energy drink craze there was limited choice when purchasing the beverage. Now you can find energy drinks with different types of flavours, strengths and different blends of ingredients.
Most popular brands of energy drinks are:
- Red Bull – the original energy drink
- Monster – the second-highest selling brand on the market
- Rockstar
- Nos
- Xyience
- Bang
- Amp
- Celsius
- Zevia
- V8 + Energy
The World Health Organization and the American Academy of Pediatrics both agree that consuming energy drinks can be unhealthy, especially for children. The American Beverage Association however believes that the drinks are safe and that many of the ingredients found in the drinks are also found in foods that we eat on a regular basis.
It is important to note that energy drinks are not recommended and can be dangerous for anyone under 18, women who are pregnant, people who have caffeine sensitivities, people who don’t consume caffeine on a regular basis and those who are taking medications such as Adderall for ADD.
What exactly is in your energy drink?
- Caffeine
- Added sugars
- Vitamins, such as B vitamins
- Legal stimulants, such as guarana (a plant that grows in the Amazon)
- Taurine, an amino acid that is found in meat and fish
- L-carnitine, helps turn fat into energy
What is concerning to the health professionals about these added ingredients is that they are often in higher concentrations than found naturally in the food or plants we consume and when you combine them with caffeine there can be a negative effect on your body.
Up to 400 mg of caffeine a day is considered to be safe for most healthy adults. That is the amount of caffeine you would find in four cups of coffee. Adolescent’s ages 12 to 18 intake of caffeine should be 100 mg per day. That is equivalent to one cup of coffee or two cans of pop. The amount of caffeine found in a 24oz energy drink is 276 mg. The popular Starbucks Doubleshot Energy Coffee in a can has 145 mg of caffeine.
Comparison of Caffeine Amounts in Popular Beverages

What can happen to your body when consuming an energy drink?
– Increased heart rate. This could be due to the interaction of caffeine with other ingredients, such as the taurine.
– Stress levels go up.
– Increased blood pressure.
– Some studies have shown that energy drinks can make the blood become a little thicker.
The effects of energy drinks on the brain
The effects of caffeine on the brain will depend on how many energy drinks you consume. Too many energy drinks and subsequently too much caffeine can result in a person experiencing anxiety, insomnia, stomach irritation, muscle twitching, restlessness and tiredness.
Sport drinks are flavoured beverages that contain water, sugar and electrolytes such as sodium, potassium and magnesium. Some of these drinks may also contain added vitamins such as vitamin C or B vitamins.
The drinks are marketed as beverages that replenish electrolytes lost during exercise, supply carbohydrates, prevent dehydration and help sustain energy levels. They help when someone is exercising for a long period of time and are sweating a lot. Athletes training and competing lose water and electrolytes by sweating and expending energy. The sports drink will help replace the sodium lost in sweat and keep you hydrated. It is best to sip on the sports drink every 10 to 15 minutes rather than guzzle it down. But, unless someone is exercising or competing for more than 90 minutes there is really not reason to consume a drink with extra sugar and electrolytes. It is believed that the intake of extra salt during exercise may actually cause stomach problems as well as salt-induced cramps. If you have been sweating for more than 45 minutes doing an activity sports drink is a better option than drinking water.
There are three major types of sport drinks:
1. Isotonic sport drinks: Contain similar concentration of salt and sugar as in the human body.
2. Hypertonic sport drinks: Contain a higher concentration of salt and sugar than the human body.
3. Hypotonic sport drinks: Contain a lower concentration of sale and sugar than the human body.
Most sport drinks are isotonic and have between 4 and 5 heaping teaspoons of sugar per 8oz. serving. A 20oz Gatorade has 34 grams of sugar.
Most popular brands of sport drinks are:
- Propel – Good if you’re looking for a sports drink that has zero calories, sugar-free and full of electrolytes.
- Scivation – Good for weightlifters who are focusing on building muscle mass. This is a sports drink that will do more than just keep you hydrated. The drink includes 7 grams of branched amino acids or BCAAs which help with muscle recovery after activity.
- Nooma – An organic sports drink that is plant-based, non-GMO and vegan-friendly. Each drink is only 30 calories with no added sugar. It contains coconut water which adds potassium to your drink.
- Gatorade – Contains electrolytes and carbohydrates and added sweet flavour. It is the most reasonably priced drink. To cut down on the amount of sugar you are consuming with this drink you can use a few tablespoons of Gatorade mixed with cold water to still get the effects of the drink without all the sugar.
How to be an Educated Consumer of Sports Drinks

If you are not consuming them for their actual purpose (high activity exercise and sports) they can have a negative effect on your body. One of the effects of drinking sports drinks with carbohydrates and not engaging in prolonged exercise is weight gain. There was a study that found that teenagers who drank one sports drink per day for two years gained 3.5 pounds. This was more weight gain than if you drank one pop every day for two years. The drinks are unnecessary for children who engage in routine physical activity.
