Exogenous Ketones: A Faster Path to Ketosis

You eat right, exercise, and (try) to keep stress levels low and positive thoughts high—all things that have been shown to improve health. Scientists hypothesize that being in ketosis can improve longevity and health. But, the ketogenic diet isn’t for everyone, and some people find it hard to commit to intermittent fasting.

Other ways of achieving ketosis, like exogenous ketones, could provide a way to get many of the health benefits of ketosis even in the moments where you fail to maintain a keto diet. Exogenous ketones have been widely researched and are increasingly being studied for potential benefits shown for the keto diet or fasting. Let’s look at how these ketone molecules can better your health and maybe even your lifespan.


Exogenous ketones are ketones that are not produced by the body. Instead, you consume them to enter ketosis without fasting or following the ketogenic diet.

Studies have shown that ketone esters can elevate levels of blood ketones to 1.0-3.0 millimolar (mM) within just 30-60 minutes, while it could take 2-4 days with a ketogenic diet or up to 48 hours of fasting to get your ketones this high.

Exogenous Ketones:
Exogenous means outside the human body. Ketones you drink or consume as supplements.


The consumer market for exogenous ketones is growing, and there are many different types out there. Here are some of the benefits and a watch out.

1. Ketone salts

Ketone salts are made up of a ketone molecule bound to a mineral like sodium, potassium, calcium, or magnesium. These usually come in a powder form that can be mixed with a liquid.

Ketone salts come with certain watch outs. To consume about 50g of ketone salt you would need to consume a lot more than the daily recommended intake of sodium, potassium, calcium, or magnesium. Studies found that ketone salts can elevate blood ketones to around 0.6 - 1.0mM—a relatively low level of ketosis.

While there are some potential side effects of ketone salts, including gastrointestinal symptoms, many studies on ketone esters have found them to be well-tolerated.

2. Ketone monoester

Ketone monoesters contain the ketone molecule β-HB bound to butanediol, a chemical often used in supplements. After they’re consumed, the bond between β-HB and butanediol is broken and the liver converts butanediol into ketones.

Ketone monoesters come in liquid form, and they raise blood ketones quickly and effectively. Studies have found that blood levels of β-HB can reach 3-5mM within 30-60 minutes and stay elevated for several hours after.

3. C6 Ketone Di-ester

The C6 Di-ester, also known as Metabolic Switch®, is a bit different from the rest. It is broken down by the body into both butanediol and two fatty acids (C6). The fatty acids stimulate natural ketogenesis, which causes the body to create ketones that are biologically identical to ones created naturally when fasting.

Ketosis is a natural state, and exogenous ketones have the potential to mimic the health benefits of ketogenic diets and intermittent fasting.

For many people, the taste of ketone esters takes some getting used to, but a little bitterness seems a good trade-off for the health benefits.


Exogenous ketones, together with or instead of a ketogenic diet and fasting, show promise for providing many of the same benefits of ketosis. If you seek to embrace healthy aging, exogenous ketones can be a good tool on that journey.
