Bodybuilders are known to train hard and diet intensely. To gain a lot of muscle mass, they lift weights often. Then, to reveal a chiseled, ripped physique, bodybuilders usually count their macros to a T and/or eat a low-carb dietWith the intense training splits and rigorous dieting comes the need for next-level supplementation.

To support their in-gym performance and recover, bodybuilders most likely need an array of different supplements. For example, a joint support supplement may help to keep bodybuilders safe while lifting heavy weights often. And to recover, a sleep aid can help them get the seven to nine hours of Z’s they need while whey protein feeds growing muscles. Not sure where to start? No worries — we rounded up the best supplements for bodybuilding to help you on your journey.

Best Pre-Workout

A good pre-workout powder can facilitate better pumps and provide you with the energy you need to kick butt in the gym.

Jacked Factory Nitrosurge

This product contains the usual pre-workout players — caffeine, energy, L-citrulline for better blood flow and therefore pumps, and beta-alanine for improved strength and endurance. We like that you can see the dosing for each ingredient, so you know what you’re getting, and that Nitrosurge contains AstraGin, a formula that enhances the absorption of each ingredient. That said, those who are sensitive to caffeine should be warned: there are 180 milligrams of the stuff per serving.

Jacked Factory’s pre-workout is affordable, comes in 13 flavors, and contains fully-dosed ingredients that may help with muscle growth, like the 1.6g of beta-alanine. 

Who Should Buy Jacked Factory Nitrosurge

  • People who need an occasional energy boost before hitting the gym.
  • Those who want a quick-absorbing, fast-working pre-workout. 
  • Folks who value transparent dosing in their supplements.

Who Shouldn’t Buy Jacked Factory Nitrosurge

  • People who can’t take or don’t want caffeine. 

Best Pre-Workout Without Caffeine

If you train late or can’t tolerate stimulants, like caffeine, there are still pre-workout options for you. Some formulas — like this one — lean on focus-enhancing and pump-inducing ingredients instead of stimulants.

Kaged Pre-Kaged Stim Free

To make up for the lack of stimulant-induced energy, Kaged relies on ingredients like tyrosine and taurine that can help improve your ability to focus on the task at hand. Pre-Kaged Stim Free still contains ingredients that promote blood flow for pumps, like citrulline, and ingredients that can help with muscle retention, like BCAAs.

If you’re an early bird and want the caffeine energy boost, this is likely not the formula for you. However, if you’re looking for a blend of citrulline, BCAAs, and tyrosine that can help keep you focused and building muscle throughout your workout, Pre-Kaged Stim Free may be a great pick. Plus, it comes in two tasty flavors — Fruit Punch and Cherry Bomb.

This pre-workout includes BCAAs, taurine, tyrosine, citrulline, and creatine — but it does not contain caffeine. You'll also find coconut water powder, which can help with hydration throughout your workouts. 

Who Should Buy Kaged Pre-Kaged Stim Free

  • People who don’t want stimulants in their pre-workout will like that this blend is caffeine-free.
  • Folks who want to improve their focus while training will appreciate the taurine and tyrosine here. 
  • Anyone who wants BCAAs in their pre-workout, so they don’t have to have a separate dedicated BCAA supplement.

Who Shouldn’t Buy Kaged Pre-Kaged Stim Free

  • People who train early in the morning and may want a pre-workout with a caffeine-based formula.
  • If you’re looking for more than two flavors to choose from, you can find pre-workouts that offer a wider variety of flavors. 

Best Whey Isolate

A whey isolate protein is better for bodybuilders because it’s filtered more thoroughly and contains fewer grams of carbs and fat. So you get all of the protein with none of the extra macronutrients.

Transparent Labs Whey Isolate

One 32-gram scoop yields you only two grams of carbs and 28 grams of protein. There’s no fat, either. The whey is sourced from naturally-fed hormone-free cows, so the product quality is high if that matters to you. But at $60 for 30 servings (or $2 per serving), you’re definitely paying a pretty penny for the macro-profile and quality whey.

  • Lifters who want just protein and little to no carbs or fat.
  • Folks who care about where their protein powder is sourced from.

Who Shouldn’t Buy Transparent Labs Whey Isolate

  • Penny pinchers; this protein costs $2 per scoop.

Best Intra-Workout

Long, rigorous training sessions can deplete your body of energy. That’s why lifters who work out intensely for over an hour may benefit from drinking an intra-workout supplement. Intra-workout nutrition has actually been shown to make a workout seem easier to lifters. (1)

Kaged In-Kaged Intra-Workout

In-Kaged’s formula offers blends of ingredients that focus on muscle building, pump, and energy. It contains five grams of BCAAs, which can help with muscle retention. It also has three grams of citrulline, which may help with pumps during your workout. And it also provides one gram of tyrosine, which can help with focus. On top of all of that, you’ll find caffeine, beta-alanine, taurine, and even coconut water powder, which may help with intra-workout hydration. 

However, this supplement is low in carbs. As you exercise your carbohydrates are depleted, which is why some intra-workout supplements will provide a dose of carbs for replenishment — this intra-workout only contains two grams of carbs, which is nothing significant. If this isn’t an ingredient you’re keen on though, In-Kaged comes in three delicious flavors — Blue Raspberry, Cherry Lemonade, and Watermelon — all of which contain no artificial colors or flavors.

  • Folks who want a low calorie intra-workout. This supplement is only 10 calories per serving. 
  • Anyone who wants potential help with focus, muscle retention, and pumps will like the formula here. 

Who Shouldn’t Buy Kaged In-Kaged Intra-Workout

  • People who don’t necessarily train at a high intensity often or for long periods of time may not need an intra-workout.
  • If you’re trying to avoid caffeine, you can find intra-workout supps without this ingredient.

Best Sleep Aid 

Sleep is vital — to your performance, your mental health, and your survival. It’s been referred to as a magic pill for athletes, and a study on Stanford Basketball players proved that more sleep undoubtedly improved their performance. (2) If you have trouble falling asleep, that’s a problem, but there are supplements designed to lure into a slumber. 

Transparent Labs Sleep Aid

One three-pill serving offers up 3 milligrams of melatonin, a hormone your body produces that regulates your sleep cycle. Taking extra melatonin has been shown to help those with sleep difficulties. (3) This sleep aid also comes with tart cherry, which contains melatonin and tryptophan, another sleep-helper. Also, zinc and magnesium, two ingredients in Transparent Labs formula, have been shown to improve sleep when paired with melatonin considerably. (4) Though, for some, melatonin can cause headaches and daytime sleepiness.

A solid night's sleep is essential for your recovery and to optimize performance in the gym. Transparent Labs sleep time formula offers up tried-and-true ingredients such as melatonin and zinc and a couple of extras like tart cherry and vitamin B6. The end result: great sleep without that groggy feeling.

Who Should Buy Transparent Labs Sleep Aid

  • People who have trouble getting to sleep regularly. 
  • Those who want a multi-ingredient sleep aid.

Who Shouldn’t Buy Transparent Labs Sleep Aid

  • Folks who aren’t comfortable or don’t like swallowing multiple pills.
  • People who many no handle melatonin well. 

Best Beta-Alanine

Supplementing with beta-alanine has been linked to a significant uptick in training performance compared to lifters who didn’t take it, potentially allowing athletes to work harder for longer. (5) If you’re a seasoned gym-goer who needs to push past plateaus, beta-alanine may be able to help you do just that.

Swolverine Carnosyn Beta-Alanine

This is a single-ingredient supplement, so there’s not a whole lot to look for other than dosage. That said, typically beta-alanine doses across the market range from 1.6g to 5g, and Swolverine provides a 5g dose, putting it on the higher end of the market. In addition to that, this product comes with 100 servings per container, making the cost around $0.60 per serving, which is a great deal. This is also an unflavored powder, so it’s easy to add to another flavored beverage or smoothie without altering the taste.

And if you want to save 15 percent per container, you can subscribe to have your product delivered before you run out next. It’s worth noting that beta-alanine can cause a tingling sensation in your skin, which isn’t inherently dangerous, but some people may not like the feeling.

Who Should Buy Swolverine Carnosyn Beta-Alanine

  • Lifters who want to work harder for longer may appreciate this research-backed performance supplement.
  • Those who want to take a single ingredient supplement versus consuming beta-alanine in a pre-workout blend. 
  • If you’re looking for a high dose of beta-alanine, this product provides five grams. 

Who Should Buy Swolverine Carnosyn Beta-Alanine

  • Novice lifters who don’t necessarily need a helping hand in the strength and performance department — yet.
  • Those who aren’t comfortable with the tingling sensation that beta-alanine can cause will want to steer clear. 
  • If you’re looking for beta-alanine within a blend (like pre-workout), you can find supplements with a more robust ingredients list that includes beta-alanine. 

Best Multivitamin

If you are looking for a supplement that may help fill in the gaps in your diet, a multivitamin can help. While it’s important to eat a diet of whole foods first and foremost, a multivitamin may be able to fill in a few nutritional gaps while also supporting a lifter’s body for rigorous workouts.

Huge Supplements Huge Multivitamin

Let’s get the con out of the way first: A serving of this supplement is four capsules. That’s a lot compared to some multivitamins that only require one or two capsules for a full dose. But if you can deal, we like this multi because it provides one of the most robust ingredients lists we’ve seen.

It contains over 30 vitamins and minerals, including zinc, vitamin D, and vitamin C, all of which can be helpful in reducing inflammation after tough bodybuilding workouts. Huge Supplements also provides calcium for joint health and B vitamins, which can help with energy. If you’re looking for a multivitamin that can pair particularly well with your training, we think you’ve found one of the best options.

Huge Supplements Huge Multi

This supplement packs 100 percent to 41,667 percent of the eight essential B vitamins into one dose. Plus, Huge Supplements includes over 30 essential vitamins and minerals overall, like vitamin K1, K2, and D, and zinc, magnesium, iodine, and calcium.

Who Should Buy Huge Supplements Huge Multivitamin

  • Bodybuilders who train hard and heavy and would benefit from a joint supplement — you’ll like the calcium here.
  • Folks looking for ingredients that can help fight inflammation may appreciate the zinc, vitamin D, and vitamin C in this supplement. 
  • Anyone who wants a robust ingredients list. This multivitamin contains over 30 vitamins and minerals, which is higher than the market average. 

Who Shouldn’t Buy Huge Supplements Huge Multivitamin 

  • People who don’t want to take a large four-pill dose should look elsewhere. 
  • Non-bodybuilders who may not need such a comprehensive multivitamin formula.

Best Creatine

Creatine is scientifically proven to make you stronger and more powerful. (6) Some creatine supplements are paired with other ingredients to increase their absorption and efficacy rate. 

Transparent Labs Creatine HMB

Transparent Labs makes one of those products. The added black pepper extract helps the creatine absorb more effectively. And according to Transparent Labs, when combined with HMB (hydroxymethylbutyrate), the creatine’s strength-boosting benefits are enhanced. This supplement comes in three flavors, which isn’t ideal for those who like to mix their creatine with other supplements like protein or beta-alanine. Also, those extras cost you: Compared to other creatine products, this one is pricey. 

Transparent Labs Creatine HMB

We like that this product includes hydroxymethyl butyrate, the main metabolite in leucine that prevents muscle protein breakdown. Plus, the blue raspberry flavor is tasty, and the blend contains no artificial sweeteners.

Who Should Buy Transparent Labs Creatine HMB

  • Bodybuilders who to want to maximize their creatine supplementation with beneficial extras.
  • Those who like drinking creatine on its own and may enjoy the flavors (tropical punch, blue raspberry, strawberry lemonade).

Who Shouldn’t Buy Transparent Labs Creatine HMB

  • Folks who are used to mixing creatine with protein powder or other supps.
  • People who don’t desire extra ingredients would rather save a little money by choosing a basic creatine monohydrate.

Best Non-Melatonin Sleep Aid

Some folks don’t react well to melatonin. Either they find it addictive, or it causes unwanted side effects such as dizziness, nausea, and daytime sleepiness. You can, however, take a sleep aid that doesn’t contain melatonin. 

Nested Naturals Luna Melatonin-Free Sleep Aid

This blend of herbs — which includes L-theanine, valerian extract, chamomile extract — is meant to put you in a state of relaxation. While this formula isn’t as powerful as one with melatonin, this is a solid option for those who want to steer clear of the stuff. And we like that this product is vegan-friendly.

Who Should Buy Nested Naturals Luna Melatonin-Free Sleep Aid

  • People who don’t want to take melatonin.
  • Vegans, as this product is vegan-friendly 

Who Shouldn’t Buy Nested Naturals Luna Melatonin-Free Sleep Aid

  • Folks who want a product that’s backed by a little more science. 

Best Essential Amino

Amino acids are the building blocks of muscle, so taking them may help prevent muscle breakdown. That said, you want a formula that has both branch chain amino acids and essential amino acids. 


BCAAs, (leucine, isoleucine, and valine) were thought to be the amino acids needed to support muscle growth for a while. In recent years, more supplement manufacturers have been adding EAAs, of which there are nine (including the three BCAAs). Ghost Amino delivers 5.5 grams of EEAs and 4.5 grams of BCAAs for a complete muscle-preservation formula. GHOST is also known for its delicious flavors, and its product is vegan-friendly. That said, the science on the efficacy of BCAAs and EEAs is mostly inconclusive, and the product is a tad pricey.


Essential amino acids (EAAs) help prevent muscle breakdown and can elicit growth. GHOST transparently gives you the correct amount of all of the EAAs and BCAAs (branch chain amino acids) you need. Their product is also soy-free and vegan-friendly. 

Who Should Buy GHOST AMINO

  • Bodybuilders who want to try and preserve muscle mass, especially during a cut.
  • People who may want to spice up their water with a low-calorie, tasty powder.
  • Folks who want to get both EEAs and BCAAs instead of just the latter.

Who Shouldn’t Buy GHOST AMINO

  • Those who aren’t sold on the product’s effectiveness.
  • People who don’t want to shell out for a relatively pricey amino powder. 

How We Decided on the Best Supplements for Bodybuilding

Bodybuilders have unique supplementation needs, and those were taken into consideration when putting together this list of the best bodybuilding supplements. 

Sport-Specific Needs

As we’ve said, bodybuilders are typically working out more often with more intensity. And that intense training is usually coupled with a restrictive diet to support muscle gain while simultaneously losing fat. For that reason, certain supps — like beta-alanine, creatine, and a sleep aid — were considered. That’s not to say non-bodybuilders can’t benefit from these products, but more intensive goals typically require a more intensive supplement regimen.


We opted for companies we trust for their transparent dosing and thoughtfully curated ingredients for brand selection. Sometimes, companies will hide lackluster doses behind blends. Instead, you want to look for products that list each ingredient and its exact dose. After all, a supplement is only as good as the ingredients that it’s made of. Blends are usually more of an issue with pre-workout supps and multis, not so much single-ingredient supplements like beta-alanine and creatine.

Supplement Interaction

All of the supplements on this list play a unique role in supporting bodybuilding goals. For example, protein helps you meet your protein macro needs, while amino acids help stop muscle protein breakdown. Both creatine and beta-alanine support strength, but they also work better together. (6) None of these supps will negatively interact with one another, though we don’t suggest taking a non-stim and standard pre-workout as it’s a bit redundant. 

Frequently Asked Questions

Do I really need all of these supplements?

No. At least not right away. If you’re new to bodybuilding or lifting weights in general, then you’ll most likely see good progress from a solid diet and training plan alone. That said, as you progress in training your body will require you to push harder and harder for more gains. Once your progress starts to stall, you can begin adding in certain supplements to your nutrition regimen.

Should I add all of these supplements to my diet at once?

Not necessarily. This is a case by case scenario. For example, if you’re having trouble lifting more weight or more reps, then beta-alanine and creatine may be all you need to keep on progressing. Or, if you just increased your calories and are having trouble hitting your protein goals, then a whey protein may be required to boost your intake. And if you’re in a cutting phase and started fasted cardio, then amino acids may be a worthwhile supplement to add. Your supplement choices can be cyclical and goal-based.

Are supplements safe?

Yeah. But you should always — always — consult with your doctor before taking any new supplement. Especially if you have a pre-existing condition. In fact, if you’re serious about living the bodybuilding lifestyle, you should consult with your doctor anyway as it’s most likely a drastic change from how you’ve been eating and lifting anyways.

Can of these supplements replace real foods?

Definitely not — they’re called supplements for a reason. Even f you’re dieting down or eating low carb, you can still get a diverse array of fruits, veggies, and meats to ensure all of your nutrient needs are being met. Whey protein should be used to help you reach a large protein intake. Some bodybuilders eat 1.5 grams of protein per pound of bodyweight. For a 200-pound man that’s equal to 300 grams of protein or three pounds of chicken breast, which is a lot of chicken.
