Ketogenic diets have been around for at least a century in one form or another, but they have really grown in popularity over the last few years. The idea is that you follow a diet with virtually no carbohydrates in it whatsoever.
This is not a low carb diet, this is a very low carb diet (less than 20g per day). After following this for 24 hours your body should be almost completely void of glycogen, the main fuel source (that comes from carbohydrates).
When this happens the body goes into a process known as ketosis – where it uses stored body fat to convert to ketones, which can be used for energy as a replacement for glycogen. Exogenous ketones are ones that are not produced in the body.
They are taken as nutritional supplements, to 1) help a person enter ketosis faster, and 2) to increase the benefits of doing so.
Supplementing with ketones can have physical and mental benefits – improving endurance, reducing appetite (great for people on diets), and increasing cognitive performance (short term memory, decision making, focus).
In this article we are going to take a brief look at five of the best exogenous ketone supplements that are currently available to buy. Starting with the best first.
1. Perfect Keto
Perfect Keto are a supplement company dedicated to selling exogenous ketones, they have two base products: Chocolate Sea Salt flavour and Peaches & Cream flavour.
They use stevia leaf as a sweetener which helps keep calories (and carbs) down to an absolute minimum and each serving contains 11.38g of Beta Hydroxybutyrate (BHB) – which is the main form of exogenous ketone.
They have spent a lot of time ensuring that their product tastes delicious which sets them apart from most companies (exogenous ketones have a reputation for tasting disgusting).
2. Nutricost Ketone Salts
Nutricost sell a stripped down version which is very no nonsense, it is unflavoured, and combines Beta Hydroxybutyrate (BHB) with Sodium, Potassium, Magnesium, and Calcium to increase the effectiveness of the ketones.
Each bottle contains 34 servings which should last you around 17 days.
If you can handle the taste then you’ve got yourself a decently priced product that will work really well.
3. Keto Drive
Keto Drive’s Beta Hydroxybutyrate supplement is all about the taste, with the orange and mango flavour being particularly pleasant.
It promises fast, sustained energy, improved athletic endurance, increased mental performance, and appetite control (which can help lead to weight loss).
The packaging is gorgeous, which should not be relevant, but is always nice to see from a supplement company.
Each container has 16 servings with 11.7g of exogenous ketones in each dose. This product may be a bit on the pricey side, but it looks good, is well dosed, and the attention to detail is fantastic.
4. Pruvit KETO//OS
KETO//OS is a exogenous ketone supplement from Pruvit.
The product comes in a caffeinated and un-caffeinated version allowing you to choose which one suits your needs.
It promises increased focus, increased energy, increased fat loss, it also mentions increased strength and improved mood.
One thing that you should be aware of is that KETO//OS contains 3g of carbohydrates, which is important for people who are trying to follow <20g of carbs per day!
5. LevelUp Keto Boost
The last product that we are looking at is Keto Boost by LevelUp, it promises instant energy, mental clarity, appetite reduction, and it also promises to preserve muscle and glycogen stores.
There appears to be around 10g of exogenous ketones (most coming from Beta Hydroxybutyrate) and Keto Boost also contains Calcium, Sodium, and Magnesium which complement it nicely.
This is a caffeine free product, and it is flavoured to taste like Raspberry lemonade. The price is pretty decent and there are 20 servings per container.
