Exogenous ketones used as an alternative fuel to carbs

We rank Ketones by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.

What it is

Ketones are small molecules that the body uses for energy. In this supplement form, they are known as exogenous ketones, which simply means they are created outside the body and taken as a supplement rather than being produced naturally by the liver.

Why it's used

These supplements are used as an alternative fuel source to carbohydrates. They are typically taken to provide the brain and muscles with energy without needing to be in a state of ketosis, which is when the body naturally burns fat for fuel instead of sugar.

How it's made

To make these supplements, manufacturers use a chemical process to combine a ketone body with a mineral salt. This creates a stable powder that can be easily dissolved in water or put into capsules for the consumer.

What it typically costs

This ingredient is generally positioned in a higher price tier. This is because the chemical synthesis required to create stable ketone salts is more complex and expensive than the processes used for basic vitamins or minerals.
