What are Keto Supplements?

Going keto is a major lifestyle change and takes a lot of getting used to. This is why we came up with this list of the best keto supplements that will help your body adapt to these changes as smoothly as possible, making the most out of your low-carb diet.

Following a cyclic ketogenic diet, you get to benefit from all the good things hormones such as testosterone can do for your body, for example more muscle mass, less body fat, increased sex drive, sustained erections, and stronger bones.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

Most keto supplements are exogenous ketones— which means they contain ketones that are created outside the body, as opposed to the ketones that the body produces when it’s in a state of ketosis.

When on a ketogenic diet, your body releases three types of ketones: acetone, acetoacetate, and beta-hydroxybutyrate (BHB).

Among these three, BHB is the one found in keto supplements because it is what the body can use most efficiently.

In this article we will also mention 3 other crucial supplements for the ketogenic diet: MCT oil, fish oil and electrolytes.

Three Types of Ketone Supplements

Ketone supplements are commonly available in various forms to cater to different customer needs, tastes, and preferences.

There are generally three categories: Ketone Salts, Ketone Esters, and MCT Oils. Knowing the differences between these three will help you choose which one suits you best.

  • 1. Ketone Salts
    Ketone salt supplements are formed when ketones are bonded to a salt (e.g. calcium, sodium, magnesium, or potassium). This results in improved absorption rate, thereby providing rapid energy. Ketone salts are sometimes referred to as “Ketone Mineral Salts” or “BHB Mineral Salts.”

    Among all forms of ketone supplements, ketone salts are the most popular. They are often available in different flavors, making them taste better and easier to swallow. They are more useful and recommended for average consumers.

  • 2. Ketone Esters
    Ketone esters are basically raw BHB ketones with no salt or other compound bound to them. This form allows for quick usage of ketones in the body, which can potentially raise the ketone levels in the blood even more.

    While providing instant energy, esters have poor taste and can be hard to consume, as reported by many consumers. Also, ketone esters are not commonly available in the market and are mostly used only in research.

  • 3. MCT Oils
    Oils—such as coconut oil or more concentrated medium-chain triglyceride (MCT) oil powder—can also be used to increase ketone levels in the body.

    However, unlike ketone salts and esters, which instantly provide energy, MCTs need to be broken down first before the body can use them for energy. They are also not as potent as salts and esters when it comes to raising ketone blood levels, since ketones are not directly ingested.

    Consuming ketones in this form means you are consuming more calories because of its caloric oil density.

In addition to the three types of ketone supplements listed above, consumers must also take note of the products that fall under the category of being NOT REAL ketone supplements.

Some products in the market may claim to have “ketones” or suggest that they help promote ketosis, but in reality they do not contain ketone bodies and have nothing to do with the process. An example of this is raspberry ketones. While it has ketones in its name, it does not contain any ketones nor help induce ketosis.

To ensure you’re getting the ketones you need, make sure to check the product label for “beta hydroxybutyrate” or “exogenous ketones” before buying.

Side Effects and Suitability

As with other nutritional supplements, keto supplements may cause side effects, which are often benign and most likely to improve as your body adjusts to the supplementation. The common downsides are:

  • Electrolyte imbalance
  • Halitosis (smelly breath)
  • Flatulence (gas)
  • Hypoglycemia

Though they provide a multitude of health benefits, keto supplements and ketogenic diets may not be suitable for everyone. 

If you are pregnant or lactating, or have medical conditions such as kidney failure, pancreatitis, abdominal tumors, gallbladder disease, or impaired liver function, it is best to refrain from using these products. In all cases, consult a healthcare professional before taking any keto supplement or going on the ketogenic diet.


Considering quality and effectiveness, Perfect Keto Base Supplement is clearly the best choice. It gives you a burst of energy and enhances your mental clarity and focus. It comes in two flavors and is gluten, caffeine, and dairy free.

If you are looking to go keto and don’t know how to start, or have gone keto but still can’t find that perfect supplement, Perfect Keto Base might be the perfect solution.

Once you include the best possible keto supplement in your diet, you might want to try sipping a cup of Keto Coffee each morning. It will increase your metabolic rate, stimulate your energy production, and get you focused early in the morning!
