People may take pre-workout supplements to delay fatigue and boost their energy levels so that they can make the most out of their exercise. Some manufacturers design pre-workout supplements specifically for women or men, but anyone can take them.

This article explains everything a person needs to know about pre-workout supplements, how pre-workouts for women differ from other types, and what to consider when choosing a pre-workout supplement.

We use “men’s” and “women’s” in this article to align with how companies market their products, but there is no need to stick to one or the other. A person should choose the product with the fit, style, and features that work best for them.

Pre-workout supplements, or simply pre-workouts, are dietary supplements that claim to boost a person’s energy levels, delay fatigue, and improve focus for optimal workout performance. And, as their name implies, people take pre-workouts before beginning their exercise session.

Pre-workouts come in various forms, including powders, shakes, canned drinks, pills, and snack bars. They vary in dosage, ingredients, and how they affect the user.

Women can take generic supplements and those designed for men. However, men and women often need to take different dosages according to body weight. Individuals also have different tolerances to supplements and react to them in different ways.

Some women’s supplements do not contain ingredients that focus on muscle mass gain, which is common in supplements marketed for men.

People who are pregnant or breastfeeding should avoid taking supplements containing certain ingredients, such as vinpocetine, caffeine, and other stimulants. Check product warnings and talk to a medical practitioner before taking any pregnancy-friendly workout supplements.

Female athletes and competing individuals should not use ingredients banned from the World Anti-Doping Agency and the National Collegiate Athletic Association.

Pre-workouts contain a combination of ingredients that aim to enhance the body’s performance during workouts. A 2018 study stated that multi-ingredient pre-workouts might be good ergogenic aids for active persons. Ergogenic means that it increases energy production and enhances performance.

Pre-workouts may produce the following benefits:

Better athletic performance

Most pre-workouts contain caffeine, a known stimulant that helps people sustain high-intensity workouts with less fatigue. One study showed that pre-workouts containing caffeine improve anaerobic power performance.

Creatine has associations with improved exercise performance and may aid post-exercise recovery, energy production, and injury prevention.

The International Society of Sports Nutrition (ISSN) advocates the use of creatine. It also states that creatine monohydrate is one of the few supplements that show consistent ergogenic benefits throughout studies.

Increased endurance and delayed fatigue

Acid accumulation results in muscle fatigue. Beta-alanine, another common in pre-workout products, may control cells’ pH levels to prevent this.

A recent study found that pre-workouts reduce feelings of exertion. Another study also found they improve muscle endurance. However, using beta-alanine may trigger pins and needles.

Enhanced strength and anaerobic capacity

Most pre-workouts contain amino acids, specifically branched-chain amino acids (BCAAs) and essential amino acids (EAAs), that aid metabolism, muscle growth, injury prevention, and energy function.

Acute citrulline malate supplementation positively affects strength and aerobic power in female master-athlete tennis players and resistance-trained females.

Many fitness enthusiasts also take pre-workouts to increase muscle mass. A 2014 study found that people taking pre-workouts with eight days of training showed more significant gains in lower body strength and lean body mass than people not using pre-workouts.

Greater alertness and focus

In a 2014 study, people reported better concentration and focus after taking pre-workout supplements.

A study found that tyrosine, a common pre-workout ingredient, enhances cognitive performance and counteracts cognitive decline under stress by enhancing dopamine and epinephrine levels in the brain.

People should research their options to find good pre-workouts for women. Some factors to consider include:


People should look for ingredients that target their exercise goals. In addition, athletes should check that sports and athletic associations have not prohibited any of the ingredients.

People should also inspect for ingredients’ dosages. They should choose products that list all the ingredients on the label rather than other products that do not specify the dosage of the ingredients.

Health conditions

People with diabetes, insomnia, or heart conditions should consider the effects of pre-workouts on their bodies, especially their heart rate and blood pressure. Also, some supplements may interact with over-the-counter (OTC) and prescription medicines a person is taking.

Stimulant content

Most supplements contain stimulants, such as caffeine, which boost energy levels during workouts. However, most of these cause side effects, such as palpitations, poor sleep, headaches, diarrhea, and increase blood pressure.


Check for product reviews online as well as the manufacturer’s website. A person could see if products have verification, approval, certification, or registration from the United States Pharmacopeia, Informed Choice, the National Sanitation Foundation, or the US Food and Drugs Administration (FDA).

  • Power smoothies: Make smoothies out of fruits and vegetables. A person can also opt to add protein shake and grains for muscle buildup. Learn about protein powder for women here.
  • Proper nutrition and sleep: Having adequate nutrition and optimal sleep ensures that a person can work out at optimum levels.

People can speak to a nutritionist or a registered dietitian for advice on pre-workouts and similar supplements. If someone is experiencing chronically low energy levels, they should talk with a doctor.

There are a variety of pre-workout supplements for women. While pre-workouts offer some benefits, they should not replace good nutrition, sleep, and a healthy diet. In addition, females and males do not need to take supplements marketed specifically for their gender or sex.

People should consider different factors when choosing pre-workout supplements, including ingredients, certifications or approvals, and what a person’s fitness goals are.
