The 9 Best Supplements for Men of 2023

Let’s get this out of the way: No supplement can replace a good diet and an effective workout program. But if you are already eating right and training consistently, a fat burner can help you lean out more, or a greens powder can fill in nutritional gaps. And when it comes to supplements for men specifically, you may look for ingredients like vitamin B12 (which men tend to lack), or zinc and magnesium, which may help boost testosterone. 

From pre-workouts and creatine to electrolytes and BCAAs, there’s a supplement for just about any goal a man could want to achieve and a lot of different companies claiming that theirs are the best. So we did the work to separate the hype from the hypertrophy and dug up some of the best supplements for men on the market.

How We Tested

Our team at BarBend has been testing supplements (and everything else gym-related) for years. For this article, we evaluated supplements based on price, taste, and effectiveness, among other things. We considered each one’s claims, then put them to the test. For instance, with pre-workouts, we’d take a dose and monitor our energy levels throughout a workout. For supplements like protein, we’d see how well the powder mixed and taste-test them. 

Best Pre-Workout for Men: Transparent Labs Bulk

Specs

• Form: Powder
• Highlights: 8,000mg of citrulline malate, 4,000mg of beta-alanine, 2,500mg of betaine, 180mg of caffeine
• Flavors: Strawberry Kiwi, Piña Colada, Blue Raspberry, Black Cherry, Peach Mango, Tropical Punch, Watermelon, Sour Grape, Green Apple, Orange, Strawberry Lemonade, Lemon Lime
• Servings: 30
• Price: $44.99

Pros

• The vitamin D, zinc, and boron in this pre may help boost testosterone levels. 
• There’s only 180mg of caffeine, which is great for those who only want a moderate caffeine kick.
• This supplement contains all-natural flavoring with zero artificial ingredients. 

Cons

• If you want creatine in your pre-workout, you’ll have to look elsewhere. 
• The 180mg of caffeine may not be enough for men who want a big jolt of energy.
• If you don’t like skin tingles, the 4,000mg of beta-alanine may not be right for you.

First and foremost, a good pre-workout is meant to give you a boost of energy and focus for your workouts. Usually, this comes in the form of caffeine, beta-alanine, and other ingredients that can help you ramp up the intensity of your workouts. This pre from Transparent Labs goes above and beyond with its inclusion of nutrients that may serve to boost your testosterone levels. The vitamin D3, zinc, and boron included here may not give you superhuman strength, but they have been linked to optimal testosterone levels. (1) 

Of course, it also has the standard pre-workout ingredients as well, including solid doses of citrulline malate and beta-alanine, which gave our tester a solid pump during their workout. The 180mg of caffeine is in the middle of the pack as far as pre-workouts go — our tester felt a surge of energy, with zero crashing after the workout. 

Also, as the name suggests, this product’s label is transparent, so you’ll know exactly what you’re taking, which can be useful if you’re stacking it with other supplements. The flavors are on point as well, tasting pleasantly sweet without being too saccharine.

Best Protein Powder for Men: Jacked Factory Authentic ISO

Specs

• Form: Powder
• Highlights: 25g whey protein isolate, 1g carbohydrates, 0.5g fat
• Flavors: Unflavored, Vanilla Oatmeal Cookie, Vanilla, Chocolate Peanut Butter, Cinnamon French Toast
• Servings: 30
• Price: $34.99

Pros

• The low fat and carbs are ideal for men who want to add lean muscle mass. 
• There’s an unflavored option, which is great for mixing into smoothies.
• At under $40 for a month’s supply, this is a reasonable price for whey isolate.

Cons

• This is a milk-based protein, so vegan athletes should try a different protein.
• There are artificial flavors in this protein, so if you’re looking for an all-natural option, look elsewhere. 

Protein is the main building block for muscle, and protein powder is perfect for men who want to pile on more muscle without accumulating more body fat. The high protein and low fat and carbs in this protein powder may be just the thing. Authentic ISO has 25 grams of protein but only one gram of carbohydrates and half a gram of fat for a total of 110 calories per serving. 

And the protein here comes in the form of whey isolate, which may be easier to digest for men who may experience issues with drinking protein shakes. This is because whey isolate is processed more than whey concentrate, which removes a lot of the lactose and fat. Plus, the five flavors include some creative options, particularly Vanilla Oatmeal Cookie and Cinnamon French Toast. 

Best Creatine for Men: Transparent Labs Creatine HMB

Specs

• Form: Powder
• Highlights: 5,000mg of creatine monohydrate, 1,500mg of HMB
• Flavors: Unflavored, Blue Raspberry, Sour Grape, Tropical Punch, Fruit Punch, Watermelon, Black Cherry, Orange Hawaiian Splash, Peach Mango, Strawberry Lemonade
• Servings: 30
• Price: $49.99

Pros

• 5,000mg of creatine monohydrate has been shown to be the effective dosage.
• The included HMB may help men retain muscle. 
• There are 11 different flavors to choose from, which is handy for those with finicky taste buds.

Cons

• If you are looking for a creatine other than monohydrate, this isn’t the supplement for you. 
• The $1.66 per serving price may be out of some men’s price range.
• This has 5mg of black pepper, so if you’re allergic, go with a different creatine.

Put simply, creatine is the fuel that your muscles use for anaerobic movements like you see in weightlifting. Having more creatine in your system can help you move more weight, which can lead to gains in strength and size. This creatine stands out for the inclusion of HMB in its formula. HMB stands for hydroxymethly butyrate, which is the main component in leucine, the amino acid that prevents muscle breakdown. This means that this creatine powder may help you retain the muscle that you already have while you work to add more. 

The creatine in this supplement is in the form of creatine monohydrate, the most researched and vetted form. Studies have shown that the 5,000mg of creatine provided here is the ideal dosage for those who want to increase muscle strength and size. (2) As an added bonus, there’s an unflavored option, so you can stack it with your favorite pre-workout without messing up the taste.

Best Omega-3 Supplement for Men: Swolverine Krill Oil

Specs

• Form: Capsule
• Highlights: 500mg of krill oil, 100mg of EPA/DHA
• Flavors: Vanilla
• Servings: 60
• Price: $29.99

Pros

• The 500mg dose of krill oil is a higher dose than other krill oils provide. 
• The vanilla flavoring cuts down on the fishy flavor. 
• At roughly $0.50 a serving, this is a solid price point for an omega-3 supplement.

Cons

• The capsules are gelatin, so pescatarians should steer clear. 
• This only comes in vanilla flavor, so if you dislike vanilla, you’re out of luck.

Omega-3 fatty acids are common in fish and seafood. Their positive benefits on the cardiovascular system are well-documented, but it can be hard to eat enough to get those benefits (especially if you don’t like seafood). That’s where supplementation comes in.This krill oil is our favorite for men because it’s loaded with 500mg of omega-3 fatty acids, which is more than the more common 300 to 400mg dose you’ll find in other supplements. This is good news for men, because omega-3s may reduce the risk of heart attacks and strokes, particularly in those with elevated cardiovascular risk. (3)

More good news: The 500mg typically contains 100mg of EPA/DHA, which may reduce the risk of nonfatal heart syndromes, as well as lower inflammation (in other words, your knees will thank you). (4)(5) And while many krill oil capsules tend to have a fishy taste, Swolverine has added a vanilla flavoring to help with the flavor. 

Best Fat Burner for Men: Instant Knockout

Specs

• Form: Capsule
• Highlights: 1,800mg of glucomannan, 300mg of caffeine, vitamin D3, vitamin B6, vitamin B12
• Flavor: N/A
• Servings: 30 servings 
• Price: $65

Pros

• This fat burner contains vitamins D3, B6, and B12, all of which men tend to lack.
• The high dose of caffeine can help men push hard through workouts, even when in a calorie deficit. 
• The green tea extract may help reduce bloating. 

Cons

• 300mg might be too much for those with a sensitivity to caffeine. 
• This has black pepper extract in it, so if you’re allergic, try a different fat burner. 

While it won’t replace a good diet and consistent exercise, fat burners can help speed up your metabolism, helping your body burn more fat, even when it’s at rest. Instant Knockout may not only help burn fat, but it can also help you eat less and push harder in the gym. The fiber from the 1,800mg of glucomannan can help men feel fuller, making them less likely to overeat, while the caffeine and cayenne pepper may help increase thermogenesis. (6)

It was also developed specifically for men, as seen by the inclusion of vitamins D3, which may help boost testosterone, B6, and B12, all of which are vitamins that are commonly deficient in men. (1)(7)

Best BCAAs for Men: Huge Supplements Huge BCAA

Specs

• Form: Powder
• Highlights: 8,000mg of BCAAs, 5,000mg of l-glutamine, 80mg of calcium, 40mg of potassium
• Flavors: Kiwi Blueberry, Bomb Popsicle, Watermelon Lemonade, Sour Grape
• Servings: 25
• Price: $39.99

Pros

• The large dose of glutamine may help reduce muscle breakdown. 
• There’s coconut water in this formula, which can help men rehydrate after a hard workout.
• Huge Supplements offers four different flavors to choose from. 

Cons

• This has artificial ingredients, so if you’re looking to avoid those, this product isn’t for you.
• At over $1 a serving, this may not work for men on a tight budget. 

Branched-chain amino acids can help your body build muscle, reduce soreness, and even stave off fatigue during workouts. Huge Supplements Huge BCAA is our favorite BCAA for men because of its high doses of BCAAs and its four tasty flavors. It has a whopping 8,000mg of BCAAs in it, which can go a long way in reducing soreness and speeding up recovery after hard workouts. (8) In addition, the 5,000mg of l-glutamine may help decrease muscle breakdown, which is great for men who are looking to pack on lean muscle. 

Now, none of that will do you any good if it’s too gross for you to choke down, which is why this supplement comes in four flavors including the nostalgia-inducing Bomb Popsicle, which can bring to mind memories of the ice cream truck rolling down your street. Huge BCAA is over a buck per serving, however, which might bump it out of some men’s price range. 

Best Greens Powder for Men: Athletic Greens AG1

Specs

• Form: Powder
• Highlights: 555mcg vitamin A, 420mg of vitamin C, 22mcg of vitamin B12, 118mg of calcium, 300mg of potassium, 154mg of digestive enzymes, 38mg probiotics
• Flavors: Pineapple Vanilla
• Servings: 30
• Price: $99

Pros

• The probiotics and digestive enzymes may help to improve gut health. 
• There are ingredients, like rhodiola rosea and ashwagandha, which may help with stress and anxiety.
• This product doesn’t taste half bad, especially for a greens powder.

Cons

• $99 for a month’s worth of product is a tough pill to swallow. 
• There’s no vitamin D in this formula, which is odd, considering how many nutrients it already has.
• A lot of the ingredients come in proprietary blends, so it’s hard to say how much of everything you’re getting. 

It can be hard for men to get everything they need just from the food they eat, which is where greens powders come in. Basically a selection of vegetables that are dehydrated and powdered for easy consumption, greens powders are intended to boost your vegetable intake and fill in your nutritional gaps. 

We love Athletic Greens’ AG1 exhaustingly long list of vitamins, minerals, prebiotics, digestive enzymes, and nootropics. Among the heaviest hitters in this group are 700 percent of your daily requirement for vitamin C, 100 percent or more of the B vitamins that men usually don’t get enough of, and 100 percent of your daily requirement for zinc, which can help keep your testosterone levels healthy. 

In addition, AG1 has 7.2 billion probiotic bacteria and digestive enzymes to keep your morning “appointment” on schedule, as well as rhodiola rosea and ashwagandha, which can help reduce anxiety. It is lacking vitamin D though, which is an important vitamin for men, but the company does offer a separate D3 product to supplement.

Best Testosterone Supplement for Men: Hunter Test Testosterone Booster

Specs

• Form: Capsules
• Highlights: D-aspartic acid (DAA), vitamin K2, vitamin D3, 300mg ginseng, 10mg boron, 30mg zinc, 200mg magnesium
• Flavors: N/A
• Servings: 30
• Price: $90

Pros

• The DAA may increase testosterone production. 
• Indole-3-carbinol (I3C) may suppress an enzyme that lowers testosterone levels.
• It’s made in FDA-registered, cGMP-certified facilities. 

Cons

• The capsules contain gelatin, so this is a no-go for vegans.
• You have to take six pills daily, which may be a hard pill to swallow for some. 

One big concern for men, especially as they get older, is dropping testosterone levels. One way to combat this is with a testosterone booster, and Hunter Test is the best of the bunch. What makes it stand out from other over-the-counter test boosters is its 3,000mg dosage of DAA, an amino acid that studies suggest may help increase levels of testosterone. (9) It also has I3C, an aromatase inhibitor, which may prevent the degradation of testosterone into estrogen. (10)

Hunter Test also contains magnesium, zinc, and boron, all of which can play a part in increasing testosterone levels, inhibiting estrogen levels, and keeping the immune system healthy. One thing to note before you buy it: The daily serving is six pills, which could be a problem for men who don’t like swallowing pills. 

Best Gut Health Supplement for Men: Transparent Labs Gut Health Probiotic

Specs

• Form: Capsules
• Highlights: 1,000mg probiotics
• Servings: 30
• Price: $45.99

Pros

• This supplement has 100 billion probiotics in it, which is more than you’ll find in most probiotic supplements. 
• The 10 different strains of probiotics in these capsules, which can provide more well-rounded gut support than the typical two or three strains you’d see in other probiotics.
• The capsules are made from hypromellose, which is vegan-friendly.

Cons

• If you don’t like swallowing pills, you’d be better off with a greens powder. 
• High levels of probiotics can cause bloating, gas, and nausea in people who are sensitive to them. 

Gut health can be an overlooked aspect of fitness, but when you’re having digestive issues, you’ll wish you’d taken better care of your microbiome. Gut health supplements are generally made up of probiotics, a selection of beneficial bacteria, and yeast that live in your stomach that can help you digest your food and keep you healthy. 

Some men prefer to get their probiotics in a greens drink or a multivitamin, but if you already have a favorite green drink or multi, Transparent Labs Gut Health is a perfect addition to the mix. This is because while most supplements offer probiotics in the low billions, this one has a whopping 100 billion probiotics in each serving. 

These probiotics come in ten different strains, which may provide you with a more well-rounded range of gut health benefits. Plus, the capsules are plant-based instead of the usual gelatin, so it’s vegan-friendly as well. 

How We Choose the Best Supplements for Men

The category of best supplements for men is a far-reaching one. To prevent ourselves from casting too wide a net, we focused primarily on categories that are commonly sought out, like creatine and protein powder. Once we had our categories down, we looked at factors like ingredients, dosage, and price to determine which ones were the best in each category. 

Ingredients

For a lot of supplements, the ingredient list should be fairly straightforward. For example, if you’re buying a protein supplement, its first ingredient should be (you guessed it) protein. But even with protein, there are nuances — different types of proteins, additives, etc. To narrow down the options, we tried to stick with ingredients that had scientific backing to their claims of effectiveness. 

When possible, we also gave preference to supplements that included ingredients that are potentially beneficial specifically to men, like vitamin D, vitamin B, zinc, and magnesium.

Dosage

Having the right ingredients doesn’t mean much if you don’t have an effective dosage, however. So, in addition to what was in each supplement, we also checked to make sure there were effective amounts of those ingredients. For example, studies show that 5,000mg of creatine can be effective in amplifying athletic performance and muscle hypertrophy, so we chose a creatine supplement that had 5,000mg of creatine. (2)

For supplements like protein powder that are designed to boost your macronutrient intake, we looked for supplements that had higher doses. A protein supplement that had 20 to 25 grams of protein per scoop received more consideration than, say, a protein powder with 10 to 15 grams of protein.

Price

No matter how effective a supplement is, it won’t do you any good if you can’t afford it, but a lot of the cut-rate supplements on the market may not have high-quality ingredients or a high enough dosage to be effective. We tried to choose picks that sat in the median price range for their categories, and when products had similar specs, we would give preference to the less expensive option. There are some higher-end supplements on this list, though; we chose to include them because they had ingredients and/or dosages that made them worth the extra cost. 

Supplement Certifications

Since the FDA does not approve dietary supplements, anyone can create and market a supplement without passing a vetting process. This puts consumers at risk of taking supplements that are, at best, ineffective or, at worst, potentially dangerous. Luckily, there are third-party organizations that test supplements for quality and potency. 

We gave preference to products that are certified by reputable organizations like U.S. Pharmacopia (USP) or the National Sanitation Foundation (NSF), as well as the NSF International Certification for Sport, which certifies that a product does not contain any prohibited substances.

Benefits of Supplements for Men

As the name suggests, supplements are intended to supplement a healthy diet and a consistent, effective workout regimen. Nothing on this list is going to get you to your goals if you’re not eating right and putting the hours in at the gym. But, if you’re taking care of the essentials, supplements can help you in many areas of health and fitness. Some of the biggest ways supplements can benefit men are by filling in gaps in your nutrition, providing nutrients that men are commonly deficient in, and helping to bolster your performance in the gym.

Pre-Workout

Designed to be taken before your workouts, pre-workouts are meant to give you an energy boost and improve your focus during exercise. This can help you get in a more intense workout and push you through days where you’re feeling sluggish. Most often, these supplements use caffeine and other stimulants like beta-alanine, which not only delivers those fun skin tingles, but can also stave off fatigue during long sets. (11)

Protein Powder

One of the more simple supplements, protein powder is for people who want to add protein to their diet without adding a lot of fat and carbohydrates to their daily macros. As the main building block for muscle, adding protein powder to one’s diet can help speed up the recovery process, helping men pack on muscle and get back in the gym sooner after a tough workout. (12)

Creatine

One of the most studied and vetted supplements available, creatine provides fuel for your muscles in the form of adenosine triphosphate (ATP). Studies have shown that adding a creatine supplement can not only help build strength, but may also help the body increase muscle mass as well. (2)

Omega-3s

Found commonly in fatty fish and other seafoods, omega-3 fatty acids can reduce the risk of negative cardiac events like strokes and heart attacks. (3) But it can be hard to get enough omega-3s to have this effect. A good omega-3 supplement can help bolster your intake.

Fat Burners

Fat burners aren’t magic pills, but they can help you lose that extra bit of fat when combined with a good diet and consistent exercise. Generally, these supplements will use ingredients like cayenne pepper and caffeine — two ingredients that studies show may increase thermogenesis, or your body’s ability to burn calories while at rest. (6)

BCAAs

Branched-chain amino acids (BCAAs) are essential amino acids that can help your body build muscle, reduce soreness, and speed up recovery after exercise. (8) While you can get some BCAAs through your diet, supplementing with BCAAs may increase their effect. 

Greens Powders

At their most basic, a greens powder is a selection of nutrient-rich vegetables that have been dehydrated and ground into a powder. This concentrates the micronutrients in those vegetables, so you can get a solid dose of them by mixing the powder in water and slugging it down.

Studies have suggested that supplementing with a greens powder for 90 days can significantly lower your blood pressure. (13)

Testosterone Boosters

Increasing your testosterone can have positive effects on a man’s energy, strength, muscle growth, and even sex drive. A test booster may help with that, especially in older men. Often, they’ll use ingredients like vitamin D, which studies suggest can help increase testosterone levels. (1) 

Probiotics

Made up of beneficial bacteria and yeast that resides in your digestive tract, probiotics can be taken to bolster your microbiome. Increasing the amount of good bacteria may help your body digest food better and fight off illness. Studies have also suggested that probiotics may even help lactose-sensitive people digest milk products (which can come in handy if you’re taking in a lot of whey protein). (14)

Final Word

Supplements can’t replace a good diet and exercise, but they can be a helpful tool for men who want to round out their nutrition or boost their performance in the gym. While there’s not one supplement that can do everything, there is a supplement in just about every category, so it’s best to know why you’re taking a supplement before you start shopping.

When looking for the right supplement for you, think about what needs you want the supplement to fulfill, then look for supplements in that category that have ingredients that are proven to be effective and are priced within your budget. You can use this list to help you get started.
