BHB salts are said to have a strong taste. In response, this all-natural product features flavors designed to mix easily and taste good so there’s no overwhelming BHB taste. 

Keto Drive supports ketosis, endurance, and mental performance. It is made using high-quality ingredients and is tested for purity.

One serving contains 11.7g of BHBs and is lower in sodium than many of the exogenous ketone supplements that are currently available. 

One advantage of these 4 BHB salts is to promote a balance of electrolytes. This is important because a lack of carbs in the diet may cause an electrolyte imbalance, which can lead to dehydration.

This product is naturally sweetened with stevia and naturally flavored, but does contain fillers. 

Still, Nutricost is a company whose products are 3rd party tested for quality. 

The unique 4-in-1 BHB salt blend makes Nutricost Keto the Exogenous Ketones with the best BHB complex.

The other ingredient that’s not typically included is 500mg of l-carnitine l-tartrate, which helps carry stored fat to be used as energy. 

The unique ingredient profile is designed to boost energy, focus, and performance while increasing levels of ketones in the blood. 

The label is fully disclosed and the taste is all-new. The strength of this formula makes Giant Sports Giant Keto the exogenous ketones with the best potency.

Keto Plus is designed to provide extended energy for training, your daily job, or school obligations.

One of the differences between Keto Plus and other products is that it provides 30 servings at a good price point. 

However, you’re only getting half the strength of BHB salts per serving. This allows for more dosing flexibility. 

The other downside is that there are a lot of “other ingredients” in this product: gums, acids, flavoring, coloring, and sweeteners. All of these ingredients are natural but it’s more than you’ll find in other options.

Buying Guide – How To Choose The Best Exogenous Ketone Supplements?

What Is The Ketogenic Diet? 

The Keto diet has become a popular low carb diet that forces the body to use stored fat for energy. This diet suggests that 10% or less of your total daily calories come from carbohydrates. Having said that, there are variations of the Keto diet:

  • Standard Keto Dieting (SKD)—This is the standard keto diet: as noted above, it’s a low carb, high protein, high fat eating plan. This version is best for people that have fairly inactive lifestyles. That means that users on this program do exercise, but not to the point that a low carb intake significantly affects exercise performance. 
  • Targeted Keto Dieting (TKD)—This version is better suited for bodybuilders and athletes because it allows carb intake in the hours surrounding the workout for better training energy and improved recovery. The goal in this case is to improve exercise performance without affecting ketosis for anything more than the time it takes to workout. 
  • Cyclical Keto Dieting (CKD)—This version is similar to the TKD approach, except it allows planned carb refeeds every 7th day to replenish muscle glycogen stores. This is the most popular version of the Keto diet among bodybuilders and other athletes. If you train intensely but feel your training performance is not at the level you want after using both the SKD and TKD versions, then the CKD version is the best choice for you.

Comparing The Keto Diet To Other Low Carb Diets

How is the keto diet different from other low-carb diets? The keto diet is designed to allow the body to enter a state of “ketosis”. This is when the body produces ketones for energy. 

Ketosis is defined by Medical News Today as “a metabolic process that occurs when the body does not have enough glucose for energy. Stored fats are used for energy, resulting in a build-up of ketones in the body”. Ketones are compounds that are synthesized in the liver and come from stored fat. This happens when carbohydrate intake is extremely restricted. Your body then uses stored fat as fuel. (1, 2)

What Are Exogenous Ketone Supplements?

Exogenous ketone supplements contain end-products that are used in the metabolism of fat. Without this supplement, users would have to fast to create a high content of ketones in the bloodstream. However, an exogenous ketone supplement provides ketones directly, which will rapidly increase blood ketone levels. This is true even if you aren’t following a strict keto diet.

Exogenous Vs Endogenous Ketones

These are the two types of ketones:

  • Endogenous ketones – These are made by the body and are the result of fasting and low carb intake.
  • Exogenous ketones – These are provided by supplements.

The “Keto Flu”

Taking exogenous ketone supplements help alleviate the negative effects caused by low carb dieting. This is known as the “keto flu”, and it’s flu-like symptoms experienced by some people when they first start the keto diet. This is caused by the body adjusting to a low carb diet. Instead of not feeling well while going into a state of ketosis, exogenous ketones provide the energy and clarity needed for your daily obligations. 

Exogenous ketones do not burn calories, they stimulate more energy and focus without experiencing the “keto flu”. So you feel OK while benefiting from the natural fat-burning state of ketosis. Having said that, it’s important to understand that by themselves, exogenous ketones are not a fat loss supplement. They burn fat indirectly by helping your body go into ketosis. You must be following a low-carb diet to get long term fat loss benefits from these products. (3, 4)

Exogenous Ketone Benefits

Here are the benefits of ketosis:

  • Fat Loss 
  • Increased Energy & Focus
  • Reduced Hunger & Cravings
  • Helps Control Blood Sugar

How To Use Exogenous Ketones

Read all label directions before using an exogenous ketone supplement. Mix one serving with water or the beverage of your choice. If you are using capsules or a liquid, use it as directed. 

The great thing about this product is that blood levels of ketones will increase quickly and should be at maximum levels within an hour. 

Exogenous ketones will maintain a state of ketosis, even if you are eating a higher carb meal. For this reason, you should take them within 30 minutes of eating. 

That could mean before a refeed meal if you are following that version of the keto diet. It can be before your first meal if you are following an intermittent fasting program. 

This supports fat loss because you are still burning fat for fuel even after you begin your eating period. 

Athletes can use exogenous ketone supplements within half an hour of starting their event. 

A second dose can be used after 3 hours if the event is 4 hours or longer. This is because after three hours, ketone levels decrease, and after about four hours, you’re back to a baseline level.


There’s a number of high quality  exogenous ketone supplements available. 

The best overall is Perfect Keto Base. This product is designed by a Doctor and features a fully disclosed label with 11.4g of BHB salts per serving. You can mix it with anything, there’s no clumps and it tastes good. 

If you want the best BHB blend, Nutricost Keto BHB Exogenous Ketones takes their BHB complex one step farther. This blend includes 4 patented goBHB salts per serving. This product is lower in sodium than many other choices and provides a good electrolyte balance. 

If you’re new to keto or low carb dieting and want to try an exogenous ketone supplement, KEPPI Keto is a simple, no-frills formula that contains 11.8g of patented BHB salts per serving. It’s naturally flavored and naturally sweetened.
