Best Pre-Workout Powder Supplements to Buy for Real Results

Via Peters

Whether you’re hitting the gym to lift weights, crushing a Peloton workout in your living room, a jog around your neighborhood, or you’re doing laps in the swimming pool; no matter what your workout routine entails, there’s no doubt that you want to make sure that you want to get as much out of it as you possibly can.

There’s an easy way to maximize your workouts. How? By taking pre-workout supplements!

Pre-workout products are specially formulated to fuel your exercise routine. Fueling up with healthful, nutrient-dense food is a strategy that has been used for ages as a way to improve energy levels and boost performance, but in recent years, the use of supplements to achieve this goal has gained serious traction.

In fact, if you have a favorite fitness influencer, you thumb through exercise magazines, or you chat with buddies at the gym, you’ve probably heard about pre-workout supplements. While the specific ingredients can vary from formula to formula, the vast majority are stimulants, such as coffee or green tea, as well as ingredients that support muscle growth and repair, such as creatine and amino acids. Various vitamins and minerals can also be added to the mix.

From pro-athletes to regular Joe’s like us, countless people use and swear by pre-workout supplements. Because they have become so popular, if you’re thinking about using a pre-workout supplement yourself, you’re going to find that there are hundreds, if not thousands, of options to choose from.

Summary of Our Top Pre-Workout Supplements for 2021

Now that you’ve read through our detailed reviews of each of the products we selected, here’s a brief summary of the pre-workout formulas that are featured on our list.

How We Rated the Top Pre-Workout Supplements for 2021

While there’s no shortage of pre-workout supplements on the market and every one of them claims to provide powerful results, they don’t all live up to their claims. In order to sift through all the different options, we used the following factors to select and rank the options that are featured on our list.

Ingredients and dosages that are backed by science. We gave preference to supplements that are made with ingredients and dosages that are backed by scientific evidence.

Claimed benefits. A lot of pre-workout formulas market great claims but don’t live up to them. We gave preference to options that actually lived up to the claims that they made.

Healthiness, safety, and testing. Some pre-workout supplements are dangerous; particularly those that are made by companies that aren’t reputable. The top-rated supplements undergo rigorous health and safety testing to ensure that they are not only effective, but that they are safe to consume.

Backed by medical professionals. Some of the pre-workout supplements that are on the market are made by marketing teams that have no experience with health. Others are made by doctors, dietitians, naturopaths, and other experts that have extensive knowledge in health. We gave preference to supplements that were formulated or made by the latter group.

Taste and texture. Many pre-workout supplements are supposed to be taken with water, and as such, you can taste them. When rating the supplements on our list, we preferred options that were flavorful and that had a smooth texture.

Reputation and ingredients. There are so many pre-workout supplements on the market, and unfortunately, some of them are made by fly-by-night manufacturers and contain poor-quality, unproven ingredients. We preferred formulas that were made by manufacturers with proven reputations of excellence and that used high-quality ingredients.

Satisfaction guarantee. When companies stand behind their products, that’s a good indication of the quality of their products and their commitment to their customers. We preferred pre-workout supplements that were backed with satisfaction or money back guarantees.

Price and value. Like any other type of supplement, pre-workout supplements vary in price and value. We preferred options that were affordably priced and that offered a good value for the money.

Serving size. The serving sizes of the pre-workout supplements that are featured on our list have serving sizes that range from 5 grams to 31 grams.

Who Should Use a Pre-Workout Supplement?

From professionals to laymen, anyone who wants to maximize their workouts can take pre-workout supplements. The following are just some of the people who might be interested in and benefit from taking these types of supplements:

  • Weight lifters
  • Bodybuilders
  • Cyclists
  • Runners
  • Swimmers
  • Professional athletes
  • Anyone who wants to support their weight loss and fat loss goals
  • Those who want to boost their endurance levels

No matter if you’re trying to boost your pump or enhance your fat burning power, with a pre-workout supplement, you can boost the success of every single workout you do.

What Does the Science Say About Pre-Workout Supplements?

Pre-workout supplements are supported by plenty of scientific evidence. Numerous studies have found that these supplements can increase physical performance and boost mental clarity, while also reducing fatigue and enhancing focus. These benefits have been confirmed by several peer-reviewed, controlled clinical trials.

In a study that was published in the Journal of International Society of Sports Nutrition, it was determined that pre-workout supplements were an effective way to boost energy levels. Other studies have also found that these supplements support cognitive health. A study that was published in the Journal of Alzheimer’s Disease found that caffeine increases the concentration and arousal levels of participants, and enhanced their moods. By taking a pre-workout supplement that contains caffeine, you may be able to enjoy the same benefits.

In another study, it was found that caffeine increase endurance levels while working out, which allowed participants to work out for longer periods of time before they felt tired. Caffeine can also boost energy expenditure by about 11 percent, which means that your cardio workouts could potentially be 11 percent more powerful and effective when you’re taking a pre-workout supplement that contains caffeine.

Do Pre-Workout Supplements Have Side Effects?

It has been found that pre-workout supplements can cause certain types of side effects. This is particularly true for people who aren’t able to tolerate caffeine and other types of stimulants well. The majority of health adults who take these supplements will experience few, if any, side effects; especially if they’re taking a high-quality formula with standard dosages. It’s important to note that it seems like supplements that are made by non-reputable companies tend to be more likely to cause negative side effects.

Some of the side effects that have been attributed to pre-workout supplements include the following:

  • Jitters
  • Anxiety
  • Sleep interruptions
  • Tolerance build-up
  • Digestive upset (constipation and diarrhea)
  • Nausea and vomiting
  • Headaches

In more severe cases, pre-workout supplements can result in liver and kidney damage; however, these side effects are very rare.

Certain ingredients have been found to increase the likelihood of bad reactions. For example, magnesium, sodium bicarbonate, caffeine, and creatine, have been linked to digestive upset. Caffeine and other stimulants have also been linked to anxiety and jitters (especially when taken at higher doses).

Dangers of Poor-Quality Pre-Workout Supplements

If you’re thinking about adding a pre-workout supplement to your routine, choosing a high-quality formula is imperative. If you use a poor-quality supplement, not only is it possible that you won’t experience any benefits, but there’s also an increased risk of side effects.

Researchers examined a number of pre-workout supplements and discovered that they offered no help. They also found that some formulas increased heart rate and blood pressure. Supplements that are made with proprietary formulas have also been found to increase the risk of adverse side effects. Proprietary labels list the overall dosages that are used in the supplement, but they don’t provide a specific breakdown of the ingredients or the dosages that are used. As such, it isn’t possible to determine how much of each ingredient you’re ingesting, and you can’t determine exactly what ingredients you’re taking. It also makes it easier for manufacturers to conceal any questionable ingredients that they may use. Pre-hormones, amphetamines, and other dangerous additives have been found in some pre-workout supplements in the past.

For these reasons, it is absolutely crucial to make sure that you look at labels to find out the ingredients and dosages so that you can ensure you are taking something that is safe and effective.

Recommend Pre-Workout Supplement Dosages

A lot of people who use pre-workout supplements take one serving about ½ hour to an hour before they plan on working out; however, some start by taking small servings and increase them overtime. For example, you may start with 0.5 servings to see how you react and get used to the ingredients, and then increase the amount when you know how your body handles the supplement.

Be sure to pay careful attention to caffeine amounts when you’re exploring serving sizes. When taken in high doses, caffeine can be extremely hazardous and even lethal. Even when taken in moderate amounts, caffeine can cause negative effects, such as increased anxiety and jitters. The recommended amount of caffeine per day is 400 mg, maximum.

According to scientific studies, the recommended doses for popular ingredients that many pre-workout supplements contain are as follows:

  • 1.25 to 2.5 grams of betaine
  • 8 grams of citrulline per day
  • 1:2 ratio of L-theanine when taken with caffeine
  • 10 grams of BCAAs (both pre- and post-workout)
  • 500 mg to 2,000 mg of taurine per day
  • 2 g to 3 g of L-ornithine
