What's the best ketone supplement?

We compare ketone esters, bhb salts and MCT oils. See the best option for your needs, be it a rapid rise or a sustained-slow-burn for satiation, focus and flow.

KetoneAid Ke4 is the fastest acting and most effective ketone supplement available.

It is the most efficient and cost-effective option to quickly attain and maintain a high performance or therapeutic blood ketone level. The chart above shows how it affects your blood ketone levels over time compared to equivalent serving  sizes of C8 MCT Oil (the fastest acting MCT oil option) and BHB salts.

To achieve a therapeutic blood ketone range of 2-4 mmol, you would have to consume:

  • 38g of Ketone BHB Salts (that's heavy!)
  • 50ml of C8 MCT Oil (3 tablespoons, which can upset the stomach)
  • 20ml of KE4 Ketone Ester (1/3rd of a bottle = 10g of ketones)
  • 120ml of Ketone Shot (2 bottles = 10g of ketones)


C8 MCT Oil like Brain Octane Oil or a C8 MCT Oil Powder (better if you have a sensitive stomach or prefer an easier and more versatile mixing powder) is best for people not on ketogenic diets who want to feel satiated and focused.

If you're already on a ketogenic diet and have raised ketone levels, then C8 MCTs may provide you with another 1mmol boost. Best used in combination with intermittent fasting. When a therapeutic or performance enhancing increase in blood ketone levels is not needed but you want the satiation, focus and energy, then MCT oils are a great choice.

A mixed MCT oil (typically C8-C10) is a more cost-effective option for those looking to support a low-carb lifestyle, but are not in need of the rapid focus and energy offered by the pure C8 options.

MCT powders are perfect for everyday lifestyle integration. They're versatile and can be added in small quantities to most drinks like coffee and meals.


What about BHB Ketone Salts?

A 38g dose of Ketone Salts (2 standard servings) can also offer a peak on par with Esters, although consuming this quantity of salts on a regular basis is a challenge due to palatability and the amount of sodium.

Ketone Salts are the most cost effective way to get into a a therapeutic range of 2-4mmol.

KetoneAid Ketone Shotcontains only the best ketone - Ketone (Mono)Ester - D-BHB bonded to R 1,3 Butanediol. It's a more economical and more palatable option compared to KE4, but without the same ketone elevation offered by the most effective Ketone Supplement: KetoneAid KE4. This is because Ketone Shot contains 5g of ketones per bottle, vs 30g in a bottle of KE4.
