The Best Supplements to Get Shredded in 2023

Are you looking for the best supplements to get shredded? You’re in the right place.

Your diet and training are the keys to success in your efforts to cut and lose fat. If those aren’t on point, no pills or powders can get you shredded.

That being said, the right supplements can be that icing on the cake that takes your cut to the next level.

This article covers the five nutritional supplements that are the best to use on a cutting diet to get that ripped body, all based on scientific evidence.

How Do Supplements for Fat Loss Work?

Many dietary supplements claim to aid with weight loss and burning fat. It’s a multi-billion dollar industry, growing every year. Some popular workout supplements are supported by scientific evidence, but many are not. 

Most supplements intended for fat loss work through these mechanisms:

  • Increase the number of calories you burn.
  • Keep you fuller for longer and decrease your appetite.
  • Accelerate your body’s fat-burning processes.
  • Reduce the amount of fat or carbs you absorb.

All four factors boil down to attaining a negative energy balance.1 You need to eat fewer calories than you burn to lose fat, and a select few supplements offer a helping hand to reach that goal.

Another factor many people forget is your lean muscle mass. If you lose ten lbs. but five of those were muscle tissue, you’re just a smaller version of your old self. Maintaining or increasing your lean body mass is essential for a successful cut.

Supplements for muscle building that help you maintain or build muscle during a cut are as important as supplements that “burn fat.”


Creatine supplements for getting shredded? Doesn’t creatine make you bloated?

While creatine is universally accepted as an excellent supplement for building muscle and strength, it can also help you during a cutting diet. Here’s how.

Creatine is the most effective supplement for boosting your exercise performance and gaining lean body mass.2 The human body naturally produces creatine, and you can get it from your diet through animal products like red meat and fish. However, you need a supplement to see any significant benefits.

Creatine has no proven fat-burning properties, but research shows that people using creatine generally lose a little more body fat compared to placebo.3

Remember that losing fat is just one part of a successful cutting diet. The other part is retaining, or even building, muscle. If you lose as much muscle as fat while dieting, you’re not going to look and perform your best. Unless you’re getting stage-ready as a natural bodybuilder, you shouldn’t lose any muscle to speak of at all during a cutting diet.

That’s where creatine can help you.

While creatine itself doesn’t help you burn fat, neither does it prevent fat loss in any way. A creatine supplement while you cut, combined with a high-protein diet and some high-intensity strength training, effectively prevents muscle loss and maximizes fat loss. By maintaining your hard-earned muscle or even aiding in muscle gain, creatine helps you reach your goal of getting both shredded and muscular.

But what about water retention? Don’t worry.

Creatine does make you retain water, but the good news is that it’s almost all inside your muscles. Creatine pulls water into your muscles, and nearly all of it ends up in your muscle cells, not under your skin.4 Therefore, it doesn’t make you “puffy.” If anything, creatine makes your muscles look fuller, precisely what you want when you show off the results of your cutting diet.

Five grams of creatine per day fill your muscle with creatine in four months. While not necessary, you can speed up that process by taking 20 grams per day, divided into four 5-gram doses, the first week.

Creatine monohydrate is the least expensive and the most effective type of creatine on the market.5 Don’t waste your money on different forms of creatine. Most studies show them to be less effective than monohydrate and never better.

Best of all, there are no known unwanted side effects associated with creatine supplementation.

Creatine might not be a fat loss supplement, but it can definitely help you get that shredded, muscular look. It’s great during a bulk but also one of the most effective supplements to maintain or even gain muscle while cutting.

Whey Protein Powder

When you’re on a cutting diet, you need more protein than usual to build or maintain muscle.

While 1.6–2.2 grams of protein per kilogram of body weight per day maximize your potential for muscle growth during calorie balance or above, you might need up to 2.7 grams per kilogram of body weight per day during a cutting diet.6 7

Getting that much protein through regular foods can be a challenge. If you’re on a fat-loss diet, you might have to cut down on everything but protein-heavy foods to reach that goal. That’s where protein supplements enter the picture, and that’s the reason you find them on this list of the best supplements to get shredded.

Protein supplements are usually very “lean,” meaning they don’t contain much fat or sugars, just pure protein. That way, you get the protein your muscles crave but without any unwanted calories.

Protein supplements help whether you’re bulking or cutting.

  • They make it easier to get enough protein during a bulk, even if you’re feeling stuffed from all the food you eat.
  • They allow you to reach your protein intake goals during a cut without getting too many calories from carbs and fat.

Whey protein, in particular, seems to be beneficial during a cut.8 Whey is one of the two milk proteins you find in dairy products, the other being casein. You absorb whey rapidly, providing you with all the essential amino acids for muscle protein synthesis.

A recent meta-analysis concluded that whey protein maximizes lean body mass or fat-free mass gain when used during a strength-training program.9 If you use creatine simultaneously, you get an even better effect. Remember that maintaining or even gaining muscle during a cut is a sign of a successful diet.

In addition, whey protein also suppresses your appetite more than other proteins, like casein and soy protein, making it easier to stay on a strict diet.10

There are several types of whey protein supplements on the market, the two most common being whey protein concentrate and whey protein isolate.

  • Whey concentrate is the least expensive and retains some sugar and fat. It also typically contains more biologically active compounds, many of which have potential health benefits.11
  • Whey protein isolate, on the other hand, is the purest form of whey protein and has a higher protein content than concentrate. Isolate contains at least 90 percent protein.

Given that whey protein isolate has a lower fat and carb content, you might be inclined to think that it’s the best option for cutting purposes. However, a recent meta-analysis found that only whey protein concentrate effectively reduces body fat.12

Overall, whey protein builds muscle, keeps your appetite in check, and might even help you with fat loss. That makes it a prime candidate for this list of the best supplements to get shredded. As an added bonus, whey protein is also associated with several health benefits and a stronger immune system.

A protein shake or two of whey protein per day helps you get enough muscle-building protein and is an excellent part of your fat-loss regimen. Twenty to thirty grams per serving maximizes muscle protein synthesis.13 You can use whey protein both as a muscle recovery aid after workouts or at any other time during the day.

Caffeine is the most popular drug in the world, and coffee, the most well-recognized source of caffeine, is one of the most widely consumed beverages. Regardless of the source, caffeine can aid you in your struggles to get shredded.

Caffeine increases your energy expenditure and may decrease your energy intake, meaning it makes you eat less.14 Drinking a large cup of coffee every couple of hours makes you burn up to an extra 150 calories per day.15 That might not sound like much. It’s the equivalent of a banana. However, it adds up over time. Everything else being equal, burning 150 extra calories per day would make you lose a kilogram of body fat in less than two months.

Caffeine also increases your fat oxidation, meaning the process of breaking down fatty acids. You can then burn those fatty acids as fuel for your body. Caffeine can increase fat oxidation significantly, up to 29%, and boost your fat metabolism.16

Several recent meta-analyses support coffee and caffeine for losing weight and body fat.17 18 Even better, if you get your caffeine from coffee, it can be “part of a healthy lifestyle to promote overall health,” according to one of the reviews.

Caffeine is often included in commercial weight-loss supplements and “fat-burners.” As such, it’s one of few ingredients in thermogenic supplements with scientific research backing its effectiveness.19

Overall, caffeine deserves a place on this list of the best cutting supplements to get shredded. It boosts your metabolism and increases fat oxidation, possibly leading to fat loss over time.

Caffeine can also increase energy levels and allows you to perform better in the gym, which is welcome when you’re on a low-calorie cutting diet.20 21 22

You can get your caffeine boost from a caffeine supplement, but if you get it from coffee, you get several potential health effects at the same time.23 For example, the chlorogenic acids in coffee are benficial for controlling oxidative and inflammatory stress.

Regardless, it is likely the best pre-workout supplement out there. If you’re looking for a performance boost, 3–6 mg of caffeine per kilogram of body weight an hour before a training session is a standard and effective dose.24

Staying away from caffeine close to bedtime might be a good idea. It can interfere with your sleep, which is very important for fat loss. Research shows that cutting back on sleep also cuts your fat loss almost in half.25 In addition, you’re more likely to overeat if you haven’t slept enough.26 According to several studies, lack of sleep makes people eat almost 400 calories more than usual. Not a recipe for getting shredded. If you could bottle sleep, it would make this list of the best supplements to get shredded.

Green Tea

Green tea is made from the Camellia sinensis plant leaves, much like any other tea. The main difference between green and black tea is that the leaves haven’t undergone the same wilting and oxidation process. Although not backed by scientific evidence, green tea has many purported health effects documented in Chinese literature for over 1,000 years.

Another possible effect of green tea is weight and fat loss. Green tea contains a natural phenol called epigallocatechin gallate, or EGCG for short. EGCG is the primary component of green tea extract; a supplement often marked for weight loss. EGCG makes your intestines absorb less of the fat and carbs you eat, reducing your calorie intake.27 28

Will you see any weight and fat loss by using green tea extract?

It’s possible. According to a systematic review and a meta-analysis, both published in the last few years, a majority of the research supports green tea extract for weight and fat loss.29 30

A twelve-week study with more than 100 overweight women found that green tea extract led to weight loss and reduced waist circumference without side effects.s.31 

In summary, research supports green tea extract as one the best supplements to get shredded. It won’t do the job for you, but a supplement containing up to 350 mg of EGCG per day might give you a helping hand during the cutting phase.

Even if green tea extract is effective for losing weight and body fat, don’t expect it to help you maintain your new shredded physique. There is no evidence that green tea extracts aids in weight loss maintenance.32

Green tea seems to be safe in moderate amounts, although some have raised concern for liver damage with high amounts.33 350 mg of EGCG per day appears to be safe if taken in the form of a supplement. If you make real green tea and get your EGCG that way, you can safely consume 700 mg of it and be sure you’re only getting natural ingredients.34


Capsaicinoids are chemicals naturally found in chili peppers. Chili does not only make for spicy dishes, but can also help you lose fat. 

best supplements to get shredded capsaicinoids

Research shows that capsaicinoids work in three ways:

  • Increased calorie expenditure
  • Increased fat oxidation
  • Decreased appetite

Capsaicinoids are thermogenic fat burners, meaning they increase your body temperature and burn calories. Adding a capsaicinoid supplement increases your daily energy expenditure by about 50 calories per day.35

While it would take years to lose a significant amount of body way through capsaicinoids alone, burning 50 calories more while adhering to a healthy diet and exercise might aid your fat loss efforts.

Daily consumption of capsaicinoids can also help you get cut by making you eat less. A 2014 meta-analysis found that two mg or more of capsaicinoids per day reduces calorie intake.36

Don’t rely on chili peppers to lose large amounts of weight or prevent obesity, but during a short-term cut, they seem effective in helping you burn a few more calories. Capsaicinoids aren’t a magic bullet of any kind, but when added to a good diet and exercise plan, they can be beneficial.37 38

As a bonus, they possess many properties that positively affect your general health.39 They open up your blood vessels to promote blood flow, stimulate the release of nitric oxide, reduce inflammation and oxidative stress, and scavenge free radicals.40

Capsaicinoids from chili pepper at a dosage of up to 10 mg per day increase fat mobilization and make you burn more calories.41 The majority of published studies use 2–6 grams of capsaicin per day. Most capsaicin supplements contain cayenne pepper, which is high in capsaicin.

Capsaicinoid supplements have a good safety profile, with the most common adverse effect being a burning sensation in your stomach. That feeling is not dangerous but might feel unpleasant. You can prevent or at least reduce it by taking the supplement along with food.

Overall, the three-pronged approach of effective fat-burning mechanisms, health benefits, and the lack of adverse effects makes capsaicinoids one of the best supplements to get shredded.

Which Supplements Do Not Work?

In addition to the few supplements that work, many don’t. Or don’t work as advertised. Here are three of the main culprits that don’t belong on any list of the best supplements to get shredded.


Branched-chain amino acid supplements or BCAAs claim to help you build muscle and prevent muscle breakdown after exercise. However, research does not support those claims.42 43

In one study, using BCAAs even lowered the basal metabolic rate by an average of 400 kcal per day.44 That’s not good when you’re trying to lose weight.

Any Supplement Claiming to Manipulate Your Hormones

Hormones can dramatically alter your fat burning potential. However, dietary supplements that claim to affect your human growth hormone, testosterone levels, or any other primary hormone are illegal or grossly exaggerating their effects.

Legal supplements that claim to “boost” your hormones don’t boost much of anything. Not enough to make any difference.

In addition, more often than not, they might contain illegal substances.45

Fat Burners

Be wary when you see a supplement advertised as a “fat burner.” They are almost always money down the drain.

A natural supplement can only help you lose weight by increasing the calories you burn or lowering your appetite. Caffeine and green tea are the only active ingredients worth anything in fat burners. There is little to no scientific support for other compounds claiming to boost metabolism and burn fat.46

If you see the rare study lending support to a fat burner, it’s usually funded by the supplement industry.47

And there is usually no money-back guarantee when you spend money on a fat burner supplement and find that it does virtually nothing.


There you have it! The best supplements to get shredded and to help you cut.

  • Creatine for maintaining lean mass and performance in the gym.
  • Whey protein builds muscle, increases satiety, and maybe even improves fat loss.
  • Caffeine for enhancing performance and boosting your metabolism and fat oxidation.
  • Green tea extract for improved fat loss.
  • And finally, capsaicinoids increase calorie expenditure, increase fat oxidation, and help you eat less.

Several of these supplements work together for an additive effect. For example, caffeine helps boost the effectiveness of green tea extract. Combining creatine and whey protein is better than using either of them alone.

Of course, no supplement is the magic bullet for fat loss. At best, any supplement intended for fat loss provides a minor benefit.

Unfortunately, there are no short-cuts on your weight loss journey. You can’t replace hard work, a good workout routine, and a proper diet if you want to get shredded and lose stubborn fat.

But if you’re looking for a helping hand, you can’t go wrong with this list of the five best supplements to get shredded.
