Common Ingredients in Pre Workout Products

Familiarize yourself with a few of the common ingredients in some of these sugar-free pre workout products, so that you will know what to expect when making purchase decisions. While there are many, many brands on the market, many of the actual formulas are surprisingly similar. That is where some factors like flavor and cost may come into play. Consider what your own health and wellness goals are and then shop for a pre workout that contains nutrients and ingredients that support those objectives.

Some common ingredients in pre workout products include these:

Branched-Chain Amino Acids (BCAAs)

BCAAs, or branched-chain amino acids, consist of three different aminos that foster muscle growth and development.


Beta-alanine is a common ingredient in workout supplements, and some users report a tingling side effect which may- or may not- be bothersome. Beta-alanine is an amino that helps reduce the build-up of lactic acid in your muscles. This is what makes them hurt after strenuous activity. Beta-alanine lowers this incidence, so you are able to work out and train more frequently, consistently, and rigorously, without discomfort.


There are a couple benefits that Caffeine brings to a pre workout formula. The first is that since caffeine is a stimulant, it can help give you a boost of energy. Also, caffeine is lauded for providing mental focus and clarity, so it offers improved cognition.

Caffeine also contributes to weight loss by burning fat and improving your workout performance. Add these perks all together and looking for caffeine in your pre workout makes good sense.


If you are familiar with supplements, Creatine is nothing new to you. Creatine is naturally made and it gives you strength as well as energy. Red meats and seafood contain Creatine, but to fully take advantage of the benefits, you need Creatine supplements. This is where pre workouts come in.


L-citrulline is often added to supplements for its inherent ability to stimulate blood flow and reduce blood pressure. This allows for more free flow of oxygen and necessary nutrients to your muscles, making them work more efficiently.

Vitamin D

Most industry gurus suggest that a person gets at least 1,000 IU of Vitamin D daily. Vitamin D offers a lot of heart health benefits, and with regular supplementation, you should see improvement in cardio performance, strength, and healing post-workout. Sure, the sun and your diet contain Vitamin D, but it may surprise you how many people are actually Vitamin D deficient. Supplements ensure that you are getting what you need for optimal wellbeing.


It is recommended that a person gets between 200 mg and 400 mg of Magnesium daily; do you get enough Magnesium in your diet? Magnesium is often found in pre workout formulas and other supplements as so many people are deficient in this nutrient. Magnesium plays many roles in keeping the body healthy, including contributing to muscle contraction and growth.


Did you know that beetroot is attributed with improved endurance and strength? It’s true- this is why beetroot is found widely in many different health and fitness formulations. Industry experts suggest that you look for a pre workout product that contains around 500 mg of beetroot for optimal effects and to see improved endurance and muscle pump, crucial for strength training goals.

Naturally, there may be other ingredients like sweeteners or flavorings added. Read the product label to learn more.

Furthermore, always look to make sure that the products you buy are tested by a third-party for potency, purity, and quality. These will be clearly stamped and identified as having been tested.

Pre Workout FAQs

What is a pre workout?

A pre workout is a supplement, typically powder form, that is consumed before you work out or engage in physical activity. These formulas usually contain nutrients, protein, and stimulants like caffeine to help inspire and improve athletic performance. These pre workout supplements also are formulated to optimize your activity so you get the most out of your exercise.

Is a pre workout product necessary?

A pre workout is necessary if you lack the stamina and motivation to work out. If you are looking to improve and maximize the time that you spend engaging in physical activity, then a pre workout makes good sense. Also, if you are new or starting your regimen, a pre workout can reduce the aches and pains that often follow a rigorous routine.

Are pre workout products safe?

Pre workouts are safe when used as the manufacturer recommends. You also need to review the ingredients on any supplement that you take to ensure that you are not allergic or sensitive to any of them. Typically, the only ingredient that some users report sensitivity with is caffeine, which is added to many formulas for energy.

Also, check the label for the use of synephrine or bitter orange peel, which are not necessarily safe for anyone to consume.

When should you take a pre workout?

Generally speaking, you should take your pre workout about a half hour before you plan to exercise or work out and expect it to last a few hours or more. The best rule of thumb is to read and follow what the product label recommends in terms of dosage amount and how to use and/or take the product safely, and for best results.

Added sugars and artificial flavorings simply may not fit into your lifestyle and regimen. Look for these highly rated, sugar-free pre workouts and make the most of your training today!
