What are Pre-workout Supplements?

Pre-workout supplements are multi-ingredient dietary formulas. Sometimes people also call them pre-workout. Pre-workout supplements are designed to boost energy while exercising and athletic performance. 

These supplements are typically powdered substances containing caffeine, amino acid, vitamins etc. Before exercise, mix the powder with the water and drink it.

What are the Ingredients Used in the Pre-workout Supplement?

Pre-workout supplements generally contain a proprietary blend of ingredients. The manufacturers emphasise that their unique blend is responsible for the energy boost. However, there is only one ingredient that produces the buzz is Caffeine

Pre-workout Supplement

Whatever the company says, the thing is, they loaded the workout supplement with caffeine. In fact, some top-selling supplements contain around 400 milligrams (mg) per dose. That is equivalent to drinking four cups of coffee. However, there are other brands that maintain the range between 150 mg and 300 mg per dose. Below is the list of ingredients that are used in the supplement.

1. Caffeine

Caffeine can increase your metabolic rate, improve endurance, and reduce fatigue. If you take caffeine before exercise, it will:

  • Stimulate the central nervous system. 
  • Enhance brain function.

So, you will be more energetic, productive, and effective during a workout after taking caffeine. Are you thinking about how much caffeine is safe to drink? Well, you should drink a low to moderate dosage of caffeine in your drink. For example, if you are 68 KG or 150 pounds, you should take 190-210 gm caffeine. Therefore, we can say that about 3 gm per kilogram of body weight.

2. Creatine

Creatine is one of the most popular elements in bodybuilding supplements. It is effective for promoting muscle growth, strength and performance while lifting heavyweights. However, you should take 5 grams incrementally over a 5–7-day cycle. Then take a 7-14 days pause before retaking it.

3. L-Arginine

L-Arginine is one of the branch chained amino acids. It also creates nitric oxide that relaxes your blood vessels during exercise. For example, if you take it before exercise, you will have better blood flow and oxygen exchange. However, there is very little scientific evidence that it can enhance athletic performance.

4. β-alanine

β-alanine is a form of amino acid. Our liver produces it naturally to promote nerve signal function. It may help you in improving your performance by delaying neuromuscular fatigue. However, there are some side effects of taking synthesise β-alanine. For example, it can overstimulate nerve cells that can cause paraesthesia.

5. Taurine

Taurine is a neurotransmitter that stabilises cell membranes and regulates the transport of nutrients throughout the body. According to research, if you use caffeine and taurine together, they may accelerate muscle fatigue.
