The main idea behind a keto diet is to push your body into undergoing ketosis, a state where it uses fat as a source of energy, rather than the glucose and starch from all the carbohydrates you may consume.

Ketosis was initially achieved by cutting out carbohydrates completely, however, that can be quite challenging. You can now take dietary supplements (in this case they are also known just as keto supplements) which help your body achieve ketosis without cutting out carbs completely.

What Supplements Should I Take On A Ketogenic Diet?

You may be wondering, what supplements should I take on keto, and the answer is simpler than you might think. It's generally recommended to take keto diet fiber supplements and electrolyte supplements such as those containing potassium, sodium, and magnesium, along with supplements containing exogenous ketones to reap the maximal benefits of it.

Keto diet
Following a ketogenic diet has its drawbacks. Electrolyte deficiency and vitamin deficiencies are the two major factors you should take in mind.

Following and maintaining a ketogenic diet has its drawbacks, the main of which is electrolyte deficiency. It is important to note that not everyone on a keto diet suffers from electrolyte imbalance, but most people do. That is why a keto booster can help you with this diet.

If you are following a keto diet, you may also suffer from vitamin deficiencies. The presence or absence of these deficiencies depends on your exact diet and lifestyle. It is recommended to take dietary supplements to combat these deficiencies and receive the maximum positive effects of the diet.

The main reason why electrolyte-containing supplements are recommended is that they are often excreted, in high amounts, through urine and the consumption isn’t that high, to begin with, leaving behind very little levels of these ions in the body.

A ketogenic diet, traditionally, is highly dependent on low-carbohydrate consumption and high-fat consumption to reduce the body’s dependency on carbohydrates and starch for energy.

Another aspect of a classic ketogenic diet to keep in mind is that sticking to a low-carb or no-carb diet is difficult and can make you feel miserable. Hence, those supplements are recommended and advertised.

When considering exogenous ketones, you can either consume ketones like BHB in the form of pills of keto or take ketosis-stimulating and enhancing fats, such as MCT oil or Medium Chain Triglyceride oil. Either way, the end result is the same, enhanced ketosis which gives you a metabolism boost and helps with slimming down 2.

According to reviews online, keto dietary supplements are known to really help with the fat-burning process while also enhancing overall health and are highly recommended for people undergoing any form of the ketogenic diet.
