The 8 Best Natural Pre-Workout Ingredients to Pump Up Your Training Session

Get the scoop on these natural ingredients for your pre-workout shake.

Written by Alex Polish
Last updated on July 27th, 2023

Your weightlifting shoes are in your bag and you’re crossing your fingers that nobody will be doing biceps curls in the squat rack when you get to the gym. You’re amped up and ready to go — and you want to make sure nothing gets in the way of you and your weight plates for a solid training session.

Or maybe you’re completely lacking energy and motivation today, and you want to help get yourself into the right gear. Whatever your situation, you’ve probably wondered at some point or another about pre-workout. To the uninitiated, taking pre-workout to fuel your sessions may seem like the line in the sand between the weekend warriors and the competitive athletes.

If you’re focused on fitness enough to want to try pre-workout, you’re probably thoughtful about what you put in your body. Here, you’ll get the scoop on the best natural pre-workout ingredients so you can get all the benefits with none of the artificial flavors.

The opinions and articles on this site are not intended for use as diagnosis, prevention, and/or treatment of health problems. It’s always a good idea to talk to your doctor before beginning a new fitness, nutritional, and/or supplement routine. None of these supplements are meant to treat or cure any disease. If you feel you may be deficient in a particular nutrient or nutrients, please seek out a medical professional.

What Is Pre-Workout?

A pre-workout is a supplement meant to enhance performance during your training session. Certain pre-workouts are meant to be all-purpose, while others hone in on a specific aspect of your training that you may want to improve. 

For example, some pre-workouts are aimed specifically at increasing your mental focus, while others are meant to improve muscle mass and endurance. Generally speaking, most pre-workouts — except the non-stim pre-workouts — contain ingredients like caffeine that are meant to give you a big energy boost.

You typically take your pre-mixed supplement — or mix the pre-workout powder into your shake or water — about 30 or 45 minutes before your workout.

What Goes Into a Good Pre-Workout?

There are no set guidelines for pre-workout ingredients so companies are free to choose their own ingredients and dosages, which can vary widely. (1)(2)

You can typically expect some combination of ingredients like caffeine, branched-chain amino acids, beta-alanine, nitrates, different plant extracts, and creatine.

Many pre-workouts also assume you’re going to be working up quite a sweat while you’re hoisting all those barbells overhead. So they’ll come with electrolytes to support your hydration needs.

What Is a Natural Ingredient?

Supplements do not have to be approved by the U.S. Food and Drug Administration (FDA). Still, once they hit the market, the FDA can perform checks on companies regarding labeling requirements. In terms of the ability to call a product “natural,” the FDA states on its website:

The FDA has considered the term “natural” to mean that nothing artificial or synthetic (including all color additives regardless of source) has been included in, or has been added to, a food that would not normally be expected to be in that food.

So if it’s got anything patented that was made in a lab, you probably won’t be considering it natural.

Remember that not everything that’s natural is necessarily healthy or desirable. For example, excess caffeine can cause jitters or nausea and may even increase anxiety in some lifters.

Best Natural Pre-Workout Ingredients

  • Green Tea Extract
  • Watermelon Juice
  • Beetroot Juice
  • Betaine
  • Cocoa Extract
  • Turmeric
  • Black Pepper
  • Lion’s Mane Mushroom Extract

Green Tea Extract

Looking for a way to get your caffeine that’s not quite coffee-based? Green tea extract may be a great pick for you. If you’re okay with having stimulants in your pre-workout, having some caffeine before your workout has been shown to increase strength, endurance, power, and speed. (3)

Green tea extract doesn’t just have caffeine, either. It also boasts the amino acid L-theanine — which is often touted as improving focus — and antioxidants, which may help support recovery after all that work. (4)(5) The L-theanine in green tea can also have a calming effect — which can be very helpful amidst all that jitters-inducing caffeine. (6)

Watermelon Juice

Watermelon contains the amino acid citrulline. Citrulline has been found to elevate the body’s level of nitric oxide — which is helpful because it helps relax your blood vessels, therefore increasing blood flow and lowering blood pressure. (7)(8) This dilation can have implications for improving blood flow to your muscles, which may stimulate nutrient dispersal and growth.

Citrulline is a non-essential amino acid, meaning that your body does produce some on its own. Still, due to its potential to give you a better pump, you might want a splash of extra watermelon goodness in your pre-workout.

Beetroot Juice

Beetroot juice comes from where it sounds like they come from — beets. In its pure form, beets contain nitrates, which can help increase endurance, improve blood pressure, and boost your oxygen uptake while you’re running or walking. (9)(10)

The more endurance and more efficient breathing you have, the better your workout is bound to be. Whether you’re doing high-rep sets or getting in much heavier, lower-volume work, efficiency is key. And beets, of all things, can help you get there.

Betaine

Betaine, also known as trimethylglycine, found in foods like spinach, beets, sweet potato, and quinoa. It is a non-essential nutrient — meaning that your body can produce it in some amounts. Your pre-workout can incorporate any combination of these ingredients or their extracts to provide this nutrient.

Adding betaine to your pre-workout can potentially have a positive effect on muscle size, work capacity, and power. (11) If you’re about to perform an explosive workout, betaine might come in clutch when you’re trying to push your plyometrics to the max. When you’re about to get after it in the gym, it’s key to feel confident in your work capacity.

Cocoa Extract

It’s not just yummy. Cocoa extract contains high quantities of the antioxidant epicatechin. This is great news for your pre-workout because epicatechin doesn’t just increase the amount of nitric oxide in your bloodstream. It helps increase nitric oxide’s bioavailability, which means that the nitric oxide you have in your body can be more effective in the presence of epicatechin. (12)

Epicatechin is also found in tea and apples. So if those ingredients show up in your pre-workout, there’s likely some epicatechin in there, too.

Turmeric

You might associate it more with tea or curries, but turmeric may be a helpful pre-workout ingredient, too. This earthy spice contains curcumin, which can significantly increase your levels of nitric oxide — which, again, is helpful for increasing blood flow to your muscles during your workout. (13)

Curcumin, a known anti-inflammatory, isn’t easy for your body to use on its own. If you’d like to include it in your pre-workout, look for your pre-workout to also include piperine — the active component of black pepper — which increases curcumin’s bioavailability. (14)

Black Pepper

Your pre-workout certainly adds some spice to your routine when you’re getting ready to lift. Adding some literal spiciness by way of black pepper — specifically, its active component piperine — can enhance the effectiveness of curcumin in your pre-workout. (14)

Having piperine alongside curcumin won’t only help turmeric do its job. It can also help bolster your body’s immune system — this is significant because your immune system can take quite a beating when you hit it hard at the gym day after day. (15)

Lion’s Mane Mushroom Extract

Inflammation is not the universal bully that one might think. Inducing inflammation through exercise is a critical part of setting yourself up for muscle repair and regeneration — i.e., muscle growth. (15) That said, too much inflammation during your workout can reduce the quality of your overall performance. (15)

Enter lion’s mane mushroom extract. Research suggests that this fungal extract can act as a powerful anti-inflammatory. (16) By incorporating an anti-inflammatory like this into your pre-workout, you can help ensure that you’ll be able to push your training to the limit without hitting a point of no return when internal inflammation builds up.

What to Avoid in a Natural Pre-Workout

If you’re on the hunt for a natural pre-workout, it’s likely that you’re looking to avoid any artificial sweeteners, flavors, or dyes. Keep in mind that a pre-workout may say that it’s sugar-free or that it contains no added sugar — but, to add sweetness, it may still include artificial sweeteners.

That might be alright with you, and it might not be. It doesn’t have to be all or nothing. Read the label and check out the ingredients for yourself before you hit that purchase button.

Keep It Natural

Strength athletes are often very concerned about what they put into their bodies. They meal prep, count macros, and measure out portions. There’s no reason you can’t be just as exacting with what goes into your pre-workout. 

The best natural pre-workout ingredients are the ones that match your goals. If you’re looking to improve blood flow, increase endurance, and get a bit of a power boost, ingredients like green tea extract and turmeric might be exactly what you’ve been looking for.
