Exogenous Ketones

If you are thinking about or are already on a ketogenic diet, exogenous ketones may be a life saver!

While the diet can be life-changing, it comes with many difficulties and full discipline is non-negotiable.

In order to stay in a state of ketosis, your carbohydrates, protein, and fats all need to be within a specific range.

Exogenous ketones have been created to help you stay in ketosis no matter what you eat.

These supplements can be utilized whether you are on or off the diet, and they are effective with helping you lose that weight nonetheless.

What are exogenous ketones and how do they work?

The term “exogenous” means “outside of” (1).

This refers to the ketones coming from an outside source and being ingested, rather than being produced within the body.

When ketones are administered through a supplement, they tend to offer the same positive results as when a person puts themselves in a state of ketosis by utilizing the ketogenic diet.


When the body is in a state of ketosis, two ketones are produced.

These are beta-hydroxybutyrate (BHB) and acetoacetate (AcAc) (2).

AcAc breaks down into acetone in small amounts and positively affects the body and brain.

BHB is found in much larger quantities than AcAc because of its stability and ability to be transferred throughout the body.

BHB must be converted into AcAc before it can be utilized by the cells.

The exogenous ketones are responsible for increasing ketone levels in the blood within 30 to 45 minutes of being ingested.

In order to know if the ketones successfully made it into your bloodstream, BHB must be measured.

These levels are usually elevated for 2 to 3 hours after taking the exogenous ketones.

How high your ketone levels are, doesn’t reflect the effectiveness of ketosis; you want your levels to fall within a middle range.

There are three different types of exogenous ketones: esters, salts, and MCT.

  • Ketone esters are compounds created by either BHB or AcAc binding to a backbone molecule. These compounds are produced in the liver during periods of very low carbohydrate intake.
  • Ketone salts are synthetic BHB compounds that are bonded to calcium, sodium, magnesium and/or potassium.
  • Medium-chain triglycerides (MCT) are a form of fat that come in many different oils.

All three of these forms are commonly used; they each have their pros and cons.

They are either naturally or synthetically derived ketones that put you into an induced state of ketosis.

It does not matter whether or not you are following a ketogenic diet while taking a supplement, as the ketone levels are raised independent of carbohydrate consumption.

This happens because the ketogenic precursors cause similar effects as partial fasting.

Exogenous ketones can be looked at as a form of ketogenic food because they aid in overall ketosis and provide the boost of ketones needed to put the body in ketosis that otherwise is achieved by the strict and restrictive diet.

What are the benefits of using exogenous ketones?

While there may be some debate on whether or not exogenous ketones are worth it, as they are newer to the market, there are many benefits of utilizing the different forms of supplements.

Despite these upsides, make sure to always consult with a physician before any utilizations.

The following are some of the major benefits:

  • Ketones are caused to be elevated to higher levels and for longer periods of time than some ketogenic diets (3).
  • There is a great potential for seizure prevention and therapy.
  • The difficulty of keeping up with the ketogenic diet is taken away.
  • There is the possibility of improved energy, mood, and focus.
  • Future research will help eliminate side effects and bad taste and allow for the combination of exogenous ketones with increased carbohydrate intake.
  • They quickly increase ketone levels in the blood, leading to ketosis.
  • They could lead to better athletic performance.
  • Recovery may be improved through protein synthesis and glycogen resynthesis.

What are the potential negatives of using exogenous ketones?

As with any other supplement, always keep the potential side effects in mind when making the change.

Exogenous ketones are still being researched through trials and both the positives and negatives are being discovered.

Here are some negatives that are important to know:

  • The effects of taking a supplement while on medications or having a medical condition is yet to be known.
  • Exogenous ketones are not regulated, and there is a variety in the quality of products on the market.
  • The potential long-term side effects have not been studied yet.
  • They are known to have a bad taste.
  • Prices can be very high.

What is the best supplement?

Keeping in mind both the positives and negatives of using exogenous ketones, Clinical Effect’s Keto BHBoost appears to be the best supplement on the market (4).

It has many positive reviews and an overall 4.8 out of 5 star rating.

This product is being backed by science and uses an optimal blend of BHB ketones that idealizes support for fitness, health, and overall performance.

This product is manufactured in an FDA licensed facility located in the United States; this promises great quality compared to others.

There is also a 100% money back guarantee if you decide within 90 days that the product isn’t right for you.

It is affordable, costing $34.95, for a container of 30 servings.

You are supposed to take 2 capsules a day with a meal, and it does not matter if you are also following a ketogenic diet, as the effects will be the same.

However, your body’s natural response to the ketogenic diet will be enhanced if you do continue to eat that way while taking this supplement.

The Keto BHBoost contains a keto proprietary formula that is comprised of the following short list of ingredients:

  • Magnesium beta-hydroxybutyrate (500 mg)
  • Calcium beta-hydroxybutyrate (200 mg)
  • Sodium beta-hydroxybutyrate (100 mg)
  • Other ingredients: magnesium stearate, rice flour, silicon dioxide gelatin

This product focuses on helping you utilize a superior cellular fuel source while optimizing physical and mental performance and increasing the rate of weight loss.

It does this by elevating your ketone levels while transitioning you into ketogenesis with few to no side effects.

Clinical Effects has only had a very small number of customers report any issues.

Most customers start to see positive results within 1 to 2 weeks.

To summarize everything mentioned, this product is widely-known for doing all of the following:

  • Enhancing fat burning
  • Optimizing performance
  • Elevating ketone levels
  • Causing ketosis without the dieting
  • Supercharging ketosis
  • Providing superior cellular fuel
  • Preventing keto flu (5)

Exogenous ketones can be produced either naturally and synthetically and come in three different forms.

They can help you with putting your body into a state of ketosis, whether or not you want to still follow the ketogenic diet.

Keep in mind both the positive and negative factors that come along with BHB supplements and always consult your physician before making a purchase.
