Whether you’re a beginner hitting the gym  or a seasoned athlete trying to up your game, pre-workout supplements can be tempting. With   claims of enhanced performance and faster results, these powders, pills, gummies, and drinks have become a mainstay in the fitness world. But before you reach for that tub of promises, it’s important to understand the science (or lack thereof) behind these products and whether they actually live up to the hype.

The benefits associated with Pre-Workout Supplements

Pre-workout supplements are designed to provide energy and aid endurance throughout a workout. They are typically taken 15-30 minutes before a workout, but can also be consumed during exercise. 

The truth is, pre-workout supplements can be a mixed bag. Some ingredients, like caffeine and creatine, have been studied extensively and shown to have real benefits for exercise performance, but not for everyone. Also, other components, like beta-alanine and nitric oxide boosters, are less well-understood and might not be worth the money. For the average gym-goer, the effects may be more modest than advertised. For instance, beta-alanine can help reduce muscle fatigue by buffering muscle acidity, but this effect is most significant for high-intensity endurance athletes. Similarly, creatine can help supply energy to muscles, but its effect on gym performance is debatable for casual exercisers.

With so many different products in the market and little regulation, it can be hard to get the quality products. In short, for most people, pre-workout supplements might not be the game-changer you’re expecting. Caffeine is the only ingredient with well-studied effects on performance, as per the National Institutes of Health, Office of Dietary Supplements. Meanwhile, simple strategies like sleeping well, drinking enough water, and eating a nutritious snack can offer many of the same benefits as pre-workout supplements. Unless you're an elite athlete, you might want to save your money and focus on the basics.

Pre-Workout Supplements : Need to Be Approached With Caution 

We spoke to nutritionist Dr. Nikita Suresh, PhD in Nutrition. She also cautioned against the indiscriminate use of pre-workout supplements. According to her, “Pre workout supplements need to be approached with caution and not recommended or consumed randomly without understanding a person's health condition.” 

She adds that pre-workout supplements can interact with certain medications and may pose risks for people with specific health conditions. For example, they can increase blood pressure, making them a concern for individuals with high blood pressure or heart diseases. She also pointed out that these supplements can affect blood sugar levels, which is particularly concerning for people with diabetes. Some pre-workouts contain additives like artificial sweeteners and maltodextrin, which may cause blood sugar spikes and, when combined with diabetes medications, could lead to a dangerous drop in blood sugar, resulting in hypoglycemia.
Dr. Suresh also highlighted the potential impact on gut health. Many people experience digestive issues when using certain pre-workout supplements, underscoring the importance of considering their individual tolerance and health status.

Lastly, she emphasised the significance of the quality and source of the supplement. It is crucial to buy pre-workouts from reliable and authentic sources to avoid harmful ingredients or contamination. This careful approach helps ensure that the supplements are both safe and effective.

Risks Associated with Pre-Workout Supplements 

While pre-workout supplements may not always achieve their intended effects, they can lead to serious health risks. According to a 2019 study published by Nutrients, pre-workout supplements can cause significant disruptions to the body’s natural processes, such as the suppression of the testosterone axis, which can result in conditions like gynaecomastia (abnormal breast growth in men). Other potential side effects include elevated cholesterol levels, which can increase the risk of heart attacks and strokes, as well as liver and kidney damage, heart problems, and abnormal clotting tendencies.

For some individuals, these products may lower good cholesterol and contribute to short stature in teenagers. Other possible consequences include infections, elevated blood glucose levels, acne, greasy skin, and reduced sperm count in men. Women may experience masculinising effects, such as a deepened voice, hair loss on the scalp, excessive facial and body hair, acne, oily skin, and potential infertility or menstrual irregularities.
Psychologically, the use of such supplements can lead to disturbances and even dependence, especially when they contain substances that disrupt hormonal balance. Women, in particular, may face specific challenges, including the development of male-pattern voice changes, hair thinning, and issues related to fertility and menstruation. These adverse effects underline the importance of approaching such products with caution and considering the long-term health consequences.
