I first started taking exogenous ketone supplements when I tried out the ketogenic diet. While I didn’t stick with this extremely low-carb diet for long, I still find benefits in exogenous ketones.
The problem is that it took me many months to weed out all the crappy products that overpromise and under-deliver.
So, before you buy the first product you find, let me show you the best exogenous ketones that we’ve tested.
Top 4 Exogenous Ketones:
- Perfect Keto Base – the BHB-based formula also suitable for the weight loss and exercise boost
- Real Ketones – sugar-free powder sticks, available in caffeinated and caffeine-free version
- Kiss My Keto – great as an appetite suppressant and mental and physical pick-up
- KetoSports KetoCaNa – very efficient weight-loss formula that comes in unusual flavors –
Our Top Products
1. Perfect Keto Base
This is one of the more well-known exogenous ketone supplements based on BHB (Beta-hydroxybutyrate) salts.
It seems like Perfect Keto Base is not just people on the keto diet who might be benefiting from this product. There are many reviews from people who have successfully used it in a normal weight loss diet and for improved exercise performance.
I also liked that it mixes easily with water, and I didn’t need to use a blender or shaker. And it also works well with smoothies as the flavors aren’t too strong.
- Users have reported getting into ketosis faster
- Provides about 12 grams of BHBs
- Comes in multiple flavor options to mix in with smoothies
- It seems to be very easy to mix with water
- Some of the flavors seem a bit fake tasting – like the chocolate one, but switching to vanilla worked well.
2. Real Ketones
Real Ketones powder sticks may be another great support for your keto diet or just your weight loss plans. Their formula apparently has one of the highest amounts of BHB per serving.
These are available in peach caffeinated and chocolate flavor, so if you prefer the caffeine-free supplements, stick to the chocolate one.
- 10g of ketones enhanced with Magnesium, Calcium, Potassium and Sodium
- Positive online comments about the measured increase in blood ketones
- There’s a caffeine-free version not to have that “fake” mental energy boost
- Sugar-free to not mess up your diet
- Some complaints about not having enough flavors to choose from
3. Kiss my Keto Exogenous Ketone Supplement
Next on our list of recommended exogenous ketone supplements is this powdered supplement from Kiss My Keto.
With 11 grams of ketones, it claims to work well for dealing with appetite suppression during fasting periods.
People on the keto diet also like that they can take it for a fast boost when the keto flu is pulling them down a bit.
- Provides 11 grams of BHBs in each serving
- Claims to work fast for mental and physical energy
- Users like that it helps them control hunger cravings
- Mixes easily with water and doesn’t require a shaker
- The mixed berry flavor is a bit sweet and overpowering due to stevia leaf extract
4. KetoSports KetoCaNa
The final one of our recommended exogenous ketone supplements, KetoSports KetoCaNa has a low overall calorie count that may make it easier to lose weight.
We also liked the variety of unusual flavors, such as Tasty Fruit Punch or Tangy Strawberry Lemonade.
- Total of 11.7 grams of BHBs
- Proven to be very efficient in helping people achieve the weight loss goals
- Lactose and dairy-free formula,without gluten and animal byproducts
- Some exotic flavors to choose from
- Some report it having a strong smell or too sweet taste
Here are the nine key factors that we carefully analyzed for all the above products. And they should be what you focus on as well.
1. Total Ketones
Each exogenous ketone supplement will have details about types of ketones and the amount in each dose. This is probably one of the most important things to look at when comparing prices.
It’s because some products might seem very expensive when you just look at the price tag. But when you see more than 25 grams of total ketones, then it tends to justify higher prices.
You’ll also need to decide on the total amount you need. If you’re trying to battle keto flu symptoms, then you’ll want one of the stronger ones.
But just for some ongoing energy boosts, a lower concentration of about 10 to 15 grams might be enough.
2. Sodium And Potassium Content
There are two reasons to pay close attention to the exact amount of sodium and potassium before taking exogenous ketones.
First of all, these minerals are electrolytes and essential for your body. But under normal circumstances, you’ll get enough of them through your diet.
Taking very large doses of these, especially for people with heart and kidney conditions, might be a health risk, so keep that in mind.
The second reason is that athletes often take other supplements that may contain electrolytes. If this is the case, then you may need to do some more careful planning around the days that you take these supplements.
3. Types Of Ketones
For a long time, people on a low-carb diet like keto relied on medium-chain triglycerides (MCT) to help them with the keto flu.
While they do deliver ketones, you probably won’t get much of a spike in levels.
And that’s where two other types come into play.
First of all, there are ketone salts that are usually tied to the electrolytes mentioned above. They may trigger nutritional ketosis quickly, but it usually doesn’t last too long.
Secondly, there are ketone esters. These are now the generally preferred type because they can trigger a ketosis state that lasts longer.
4. Side Effects
People who start out with the keto diet have enough to be dealing with the transition phase. The last thing you want is some other side effects that might impact how effectively you’re losing weight.
One thing to look out for is the number of electrolytes. If you’re a highly active athlete, then these may be welcome. But for many people, it can make them nauseated while constantly feeling thirsty.
Also, look out for the artificial colors, flavors, and sweeteners. These could cause problems for a weight loss diet and actually make you store more body fat.
5. Powder Or Pills
There are a few exogenous ketone supplement products that come in the form of pills.
Personally, I don’t like taking them, because they are often quite large and you have to take a few of them.
The powders or pre-mixed drinks tend to be a lot more convenient. They also allow you to adjust the dosage a lot easier.
For some people, that will be an important factor to ease their body onto a new supplement, especially if they have a sensitive stomach.
6. Doses Per Day
Another thing you want to look at is whether the exogenous ketone products allow you to spread out the intake across multiple doses per day.
This is especially helpful during the transition phase, where you might want to keep blood ketone levels boosted for longer.
But it might also be helpful to boost your energy levels for college or work in the morning, and then again for a gym workout in the afternoon.
Check out the recommended instructions on the label of each product if this is something you’re planning for your weight loss diet.
Unfortunately, there are plenty of exogenous ketones supplements that taste like crap.
The diet supplement industry, in general, is plagued by this issue, but it is getting better.
Try and find a product with subtle and natural flavors, and the best way to find these is to look at the online reviews.
People will very quickly comment about the flavor if it’s crap.
Also, most keto supplements will rely on sweeteners like stevia so that they don’t taste completely bland. But too much stevia has quite a negative impact on the taste and can turn your taste buds inside out.
If your exogenous ketone supplements are a bit on the lumpy side, you can solve that with a blender or shaker. But it’s annoying and inconvenient if you want to take the supplement while on the go.
Ideally, the powdered supplements should immediately dissolve in a glass of cold water and require no more than a quick stir with a spoon.
If you want to be 100% sure you don’t have to swallow a messy drink, then pick one of the pre-mixed options.
9. Other Benefits
I generally recommend that you approach your exogenous ketone supplementation with an isolated approach.
Basically, each supplement should focus on one area and do it well. Buy a product with pure ketones that actually raise blood ketones, and if you want some other benefits, then buy a different product.
Pretty much all the multi-mineral supplements with keto salts that we looked at were mediocre at best.
And you don’t want to end up wasting money on products that don’t help you to lose weight in the best possible way.
Do exogenous ketones really work for the keto diet?
Yes, exogenous ketones can really work for the keto diet, but they are not a replacement for a low-carb diet approach. The effect will last for a few hours, but if you want all the benefits of the keto lifestyle, then you’ll have to control your carb intake.
Is MCT oil an exogenous ketone?
No, MCT oil isn’t an exogenous ketone. It is a precursor to ketones, which means that it may help your body boost ketone levels slightly after the oil has been transformed. Exogenous ketones have a much more direct impact than endogenous ketones.
Do exogenous ketones get you into ketosis faster?
Yes, exogenous ketones can get you into ketosis faster. But the effect may be limited to a few hours and doesn’t have the same benefits for losing weight as a constant metabolic change.
Do exogenous ketones give you diarrhea?
No, generally speaking, exogenous ketones don’t give you diarrhea. Some keto salts might cause stomach upset and, in larger doses, could trigger diarrhea. But keto esters tend to be the safer option and may have fewer chances of side effects.
Have You Picked Your Exogenous Ketone Supplements?
After all of our testing, we decided that Perfect Keto is the best exogenous ketones supplement. It has a refreshing flavor that easily mixes with water or other smoothies. And you can also spread each bottle out over the day for a more even effect on your metabolism.
It also has a decent concentration of exogenous ketones, which should help newcomers boost their ketone bodies during the transition phase.
