Pre-Workout Supplement Safety: A Comprehensive Guide

Pre-workout supplements are taken before a workout to boost energy and enhance athletic performance.

Caffeine, beta-alanine, BCAAs, creatine, and nitrates are five key ingredients to look for in a pre-workout supplement.

  • Caffeine improves mental clarity, lowers pain perception, and improves blood flow.
  • Beta-alanine reduces lactic acid buildup, improving muscle endurance and delaying fatigue.
  • BCAAs help reduce muscle breakdown, increase protein synthesis, and provide energy during exercise.
  • Creatine helps produce energy during exercise, improves performance, increases strength, and promotes muscle growth.
  • Nitrates increase blood flow, improving exercise performance, lowering blood pressure, and reducing the oxygen cost of exercise.

What are Pre-Workout Supplements?

As the name suggests, they are taken before a workout to help boost performance, particularly energy levels. While caffeine is the most common ingredient in most pre-workouts, there are other ingredients that can deliver additional benefits, such as improved pump, increased strength.

What Should You Look for in a Pre-Workout?

There are five main ingredients to keep an eye out for: caffeine, beta-alanine, branched-chain amino acids, creatine, and nitrates. Each of these ingredients plays a crucial role in preparing your body for a workout, whether it's by providing energy, improving strength, increasing blood flow, or facilitating another reaction that helps build muscle mass.

Caffeine is a stimulant that speeds up your central nervous system, helping you feel more alert and focused. While caffeine is a common ingredient in pre-workouts, not all supplements contain it. Studies have shown that caffeine can improve mental clarity, lower pain perception, and improve blood flow, all of which are essential for athletes.


Beta-alanine is an amino acid that helps increase muscle endurance by reducing the buildup of lactic acid. Studies have shown that beta-alanine can improve exercise performance and delay the onset of fatigue.

Branched-Chain Amino Acids (BCAAs)

Branched-Chain Amino Acids (BCAAs) are a group of three essential amino acids: leucine, isoleucine, and valine. They help reduce muscle breakdown, increase protein synthesis, and provide energy during exercise.


Creatine is a naturally occurring compound found in the body that helps produce energy during exercise. Supplementing with creatine can improve exercise performance, increase strength, and promote muscle growth.


Nitrates help increase blood flow by widening blood vessels. Studies have shown that nitrate supplementation can improve exercise performance, lower blood pressure, and reduce the oxygen cost of exercise.

Are Pre-Workouts Worth the Money?

While they may be helpful in providing a little extra energy and allowing you to do a few more reps, it's important to track how they affect your body and conduct thorough research before investing in them. As with any supplement, it's always wise to approach them with caution and only take them after consulting with a healthcare professional or a registered dietitian.

When Should You Take Pre-Workout?

According to most supplement manufacturers, it's best to take them around 20-30 minutes before you start your workout. However, everyone's body is different, and you might need to adjust the timing to suit your metabolism.

A Warning Against Dry Scooping

It's important to note that you should never dry scoop pre-workout supplements, despite the trend's popularity on TikTok. Some people believe that dry scooping maximizes the supplement's effects, but this is a dangerous myth. Dumping the whole load into your mouth can lead to instant absorption, which can cause serious health problems. Instead, always mix the supplement with water to allow your body to absorb the ingredients properly.


In conclusion, pre-workout supplements can be a helpful tool for those looking to enhance their workout performance, but it's crucial to approach them with caution and only take them under the guidance of a sports nutrition expert or a healthcare professional.
