Find out which keto supplement is the best for your body type and fitness level

Keto supplements are taking the world by storm because the right ones can provide the balance of fats that your body needs to get your body into that state of ketosis.

Those of you who have tried this form of weight loss before are aware of how hard it can be to get your body to adapt to such a dramatic change in your daily intake of food, especially without the help of keto supplements. 

Getting proper assistance from these keto supplements is why we will go deep in the science behind this fascinating diet and then review some of the best ketone supplements out there today. Because without the knowledge and the right information about these products that you can properly follow, you might never reach your goals and you may as well keep eating pizzas for lunch and mashed potatoes for dinner.

But before we get into the different keto supplements, let's dive in real quick into the our favorite products that can easily lead you into ketosis.

Here are 5 of the top exogenous ketones to help you adjust and maximize your low carb diet.

The 14 Best Keto Supplements:

It’s hard to get all of the nutrients your body needs on ANY diet. Keto especially.

Ask anyone you know who’s on keto and they’ll tell you it’s AMAZING...but a little bit extreme (maybe crazy!). It will definitely get you awesome results fast, but since most people are used to eating a high-carb diet it does present a few challenges—namely, the keto flu, low energy levels, and nutrient deficiencies.

While keto supplements aren’t necessary on the keto diet, they definitely make your life WAY easier and can even help you kickstart ketosis, have more energy, lose more weight, and be your best you.

The only problem is that there are too many to choose from (and not all are good for different keto'ers). So we whiddled the list down to the 14 best that are easy, effective, and simple to incorporate into your lifestyle.

Here are some of the best supplements we recommend to take while on the keto diet:

best keto supplements
  • Fish oil
  • MCT oil
  • Sodium & Potassium (Electrolytes)
  • Magnesium
  • Vitamin D
  • Chromium and Alpha Lipoic Acid (ALA)
  • Creatine
  • Hydroxymethylbutyrate (HMB)
  • Tribulus
  • Digestive Enzymes
  • Carnitine (in L or Acetyl-L-form)
  • Glutamine
  • ECA Stack
  • Exogenous ketones

1. Fish Oil

Omega-3 fatty acids are essential for protecting the brain, combating fat molecules in the blood (triglycerides), and fighting inflammation. They are also a great way to stay in ketosis and prevent heart disease. Most people (especially when doing keto) don’t get enough of them (1). 

During keto, you’re going to take in more omega-6 fatty acids (2) that are known to promote inflammation. Upping your omega-3 intake can counteract this and offer a ton of other health benefits.

While you definitely want to eat healthy foods high in omega-3s (salmon, avocado, etc.), just one dose of this keto supplement will do wonders for your health (3).

Fish Oil

2. MCT Oil


MCT oils are like the duct tape of the keto world: they hold everything together and make life way easier.

Medium-chain-triglycerides are fats that are easily absorbed by the body and provide a number of really powerful health benefits. Fast energy (4), appetite control for better weight loss (5), increased ketone levels, —you name it. They are also one of the most convenient and flexible, too. Add it to a shake, make a smoothie, or take a spoonful of it straight with some water for a quick, healthy keto boost that lasts all day. If you’re the kind of person that struggles to stick to a diet or eat a lot throughout the day, MCT oils are the perfect keto supplement (6).

3. Sodium & Potassium (Electrolytes)

Keto flu—we all get it. In the first few weeks, your body is going through an extreme adjustment process as it slowly realizes you aren’t feeding it the way it’s used to. As you shed water (you WILL SHED WATER), you will always lose electrolytes fast (7).

Loss of electrolytes could lead to headaches, lack of energy, and cramps, so it’s important to supplement your levels of sodium and potassium to counteract these symptoms (8). Table salt and bouillon are time-tested methods of getting more sodium into your diet. For potassium, try leafy greens, nuts, and avocados (9).

Sodium & Potassium

4. Magnesium


Magnesium (10) is another key electrolyte that keto'ers struggle to get enough of (11). This mineral boosts energy, protecting your body from everything, and regulating your blood sugar (12). It also helps regulate mental function, reducing mental fog and improving focus.

Watch your diet very closely, as it’s easy to develop magnesium deficiency when on keto. If you start to experience fatigue, cramps, or headaches, start taking a supplement: 200-400 mg per day ought to do (13).

5. Vitamin D

Vitamin D is a vital nutrient that most people (14) struggle to get enough of. Its functions range from immune health to cell growth and strong bones. There are few natural sources (15) of it (our bodies get it mostly from sunlight and a few select foods), so taking a supplement in general is a good idea whether you are on keto or not.

Vitamin D

6. Chromium and ALA

Chromium and alpha lipoic acid (ALA) work in tandem to help metabolize glucose in the blood. You see, glucose is normally stored in the body to be used as energy. When you supplement your intake of these two antioxidants, it helps you burn energy faster and move you into ketosis quicker (16).

ALA also has shown to help protect the mitochondria in your cells, enhance insulin sensitivity, optimize blood sugar levels, and has a few other key health benefits.

Chromium and ALA

7. Creatine


Keto is great, but it’s even better when combined with crushing it in the gym. If you want a supplement that helps you get that extra oomph in the gym to get bigger muscles and a sculpted physique (or just great weight loss results), creatine (17) is your best bet.

Creatine is an amino acid that increases endurance (18), and as we age our bodies produce less and less of it. Since keto should be combined with a challenging workout regimen, taking a supplement to increase weight loss, muscle endurance, and strength building is a great idea!

8. Hydroxymethylbutyrate (HMB)

Pronunciation aside, HMB is a great ally to have in your corner in the fight against fatigue and muscle loss (19). The first few weeks of a keto diet are tough enough. When you combine that with tough workouts it gets even harder (especially if you’re a beginner).

HMB has anti catabolic effects, meaning it helps fight the breakdown of your muscles. So if you’re going to be starting a workout program while on keto, this supplement will help take your workouts to the next level and build bigger muscle mass (20).

Hydroxymethylbutyrate (HMB)

9. Tribulus


Tribulus is a common keto supplement that ketoers (mostly males) use to boost their testosterone levels (21). While healthy fats on the keto diet have been shown to increase testosterone levels, taking tribulus can magnify those results even further.

It isn’t necessary and doesn’t have major health benefits, but it can help you achieve much better results with each workout (hey, you’re doing keto to look good, right?).

10. Digestive Enzyme Blends

Keto is great, but it’s not always great on the digestive tract.

Keto is high fat, moderate protein, low carb, which kind of turns your normal diet on its head (22). All of the extra fat (HEALTHY FATS) can lead to some unpleasant digestive issues (we aren’t going to name names).

Taking a digestive supplement that contains both protease and lipase enzymes (23) can help ease nausea and other symptoms that most people encounter when starting keto.

Digestive Enzyme Blends

11. Carnitine (in L or Acetyl-L form)

Carnitine (in L or Acetyl-L form)

Carnitine comes in two forms, one is more specialized for keto but they both provide key health benefits for people on the diet (or in general), and they can both be taken at the same time.

L-carnitine helps metabolize fat for energy so ketoers will use it as a supplement to get a metabolic boost. Basically, it helps you achieve weight loss faster and turn fat stores into energy. Acetyl-L carnitine is more of a general health supplement that has shown to have positive effects on the brain (24).

Take this supplement to help propel you into ketosis and burn more fat.

12. Glutamine

Are you an extreme keto dieter who wants to give it their all in the gym? Glutamine is a must-have supplement in your diet.

Glutamine is an amino acid (25) that acts as an antioxidant in your body, which can both boost your performance in the gym and fight the free radicals that extremely intense exercise produces.

When you’re on keto, you’re cutting way back on carbs which also means you may struggle to get enough antioxidants. So now you’re in a catch-22: you don’t want to increase carb intake but you need more energy in the gym and antioxidants in your blood.

Glutamine solves that issue. Taking a dose of glutamine daily will decrease your recovery time, leading to better, more productive workouts.


13. ECA Stack

ECA Stack

This cool acronym for ephedrine-caffeine-aspirin is a serious keto cocktail that will boost your energy levels, increase your metabolism, and help you achieve short-term fat loss.

We recommend this only for serious ketoers, and you should have a talk with a medical professional first. Some people can have serious complications if they have existing cardiac issues.

You probably know caffeine and aspirin, but ephedrine is usually a mystery to new keto users. It’s the main agent that spurs on fat consumption, meaning it increases the amount of fat available to be turned into energy. An ECA stack as a keto supplement can help you get great results. You just need to exercise some caution.

14. Exogenous Ketones

The goal of the keto diet is to put your body into a ketotic state (where your body has raised ketone bodies). Exogenous ketones (26) are a healthy “shortcut” to getting there. There’s no substitute for hard work, but taking exogenous ketone supplements can help you reach ketosis quicker and stay there longer.

Many dieters take them to increase their margin for error and jump into a ketotic state faster. Also, some research shows that they can help improve athletic performance (27), control your appetite, and improve mental function. Just one scoop can give you a healthy boost that turbocharges your diet results and improves your workouts.

Exogenous Ketones

So... Do Exogenous Ketone Supplements Really Work?

Good question. There have been many tests and studies that have been conducted to see if ketogenic supplements genuinely do work and many of these studies have shown that ketosis theories are correct. Adding ketones to your body and using fats as a resource of energy has some fantastic effects and if done right can help your body fight all sorts of ailments such as cancer, heart disease, diabetes and many other illnesses that can only be cured by chemical therapy. Keto therapy or nutritional ketosis is paving the way for more natural solutions, and it's a good thing that scientists have created these exogenous ketone supplements that help us induce more ketones in our body.

However, it's important to NEVER overlook the power of exercise and of course sticking to a proper routine to get the most optimized results. The most common mistake people make is by treating any keto supplement like a "wonder drug" that will help them shed weight in their sleep. Seriously... how is that even scientifically possible. So if you are thinking about trying out a particular keto supplement, I would suggest two things:

1. Check out our reviews to help you get an idea of which beta-hydroxybutyrate supplement is best for you.

2. Be realistic about your expectations of the results produced. If you are serious about your health goals and have decided to take action by taking only the best exogenous supplements, then don't forget to tie it in with a good exercise or training routine and sticking to the plan.

From my personal experience, there are plenty of ketogenic supplements that certainly do work, but you do have to be careful of the "phonies." You can find highly recommended ketones products that are endorsed by celebrity life coaches such as Timothy Ferris and Joe Rogan; then you also have those infomercial products that are probably as effective as eating Tic Tacs, which is why it is really important to do your research before experimenting. Once you are finished scouring this website full of its information, you should be well-equipped to make a calculated decision on whether this whole thing is for you and that means our mission is complete.

Testing Your Ketone Levels

I’m often asked if it’s necessary to buy and use keto products like urine sticks. They’re small test strips that you dip in urine to see if your body is producing ketones (and therefore indicate if you’ve entered ketosis.) There's very little information on how to know that you are in ketosis other than using these ketones supplements because they are as accurate as can be in determining your current state. Outside of that, you can only guess if you are in it or not by your body's performance.

a chart explaining your levels of ketones in the blood and urine

It comes in a small bottle that usually contains 50-100 strips depending on the type you choose. It’s very thin, and on one end there’s a small square of paper (this is the end you dip in the urine). If there are ketones in your urine, the little paper will change color. The darker it is (light pink up to a purple color) the more it is in your urine. On the bottle, there’s a picture you compare the color of the paper with that can be a very good indication of your current ketone state. 

Above is a color chart to help guide you when you are testing for ketosis levels so that you can track your performance. The chart is relatively simple; it's in shades of purple, except for those that have a negative trace of ketones. Check it out above.

Where Can I Buy Exogenous Ketones?

There are many places where you can buy ketone supplements especially online. You have Amazon, Craigslist, and eBay to name a few but the thing with that is, they are often over-priced compared to the actual costs from the direct manufacturer. If you buy ketones directly from the official website of the product or brand, you are likely to get a way better deal than buying from any third-party seller that you might bump into on the internet. 

So, now that we've established that purchasing BHB supplements directly from the manufacturer is the way to go. Now, let's talk about which ketogenic product you should be buying in the stores. Well, if you read our review about the different exogenous ketone supplements, you will also know that Perfect Keto is rated #1 on our list which was a pretty close race but it came out on top after all the tests that we've performed on all the different products.
