So, what’s inside this supplement? Is Keto BHB a promising supplement? Let’s find out more below.

Purely Optimal Keto BHB Ingredients

The main ingredients of Purely Optimal Keto BHB are calcium beta-hydroxybutyrate, sodium beta-hydroxybutyrate, and magnesium beta-hydroxybutyrate. These ingredients are combined in Keto BHB’s ingredient list and named “BHB Proprietary Blend.”

Keto BHB specifically works by aiding in inducing ketosis in your body. This is why this works best (and in fact, only on) the ketogenic diet. While this may sound limiting, this can work well with people who chose to follow the ketogenic diet.

The beta-hydroxybutyrate (BHB) of Keto BHB is said to aid in weight loss, energy levels, focus, and possibly even athletic performance.

Purely Optimal Keto BHB Benefits

Purely Optimal Keto BHB provides a large number of various health benefits, including using fat as fuel, assisting in ketosis, boosting physical performance, increasing cognitive function, and managing cravings. Below we will take a more thorough look at each of these benefits.

Purely Optimal Keto BHB Benefits

1) Aids In Using Fat As Fuel

To begin with, this is essentially what the ketogenic diet aims to achieve – by lowering (or even temporarily eliminating) carbs from your diet, your body will be forced to use fat – specifically, ketones – as its fuel once it is depleted of carbs and glycogen.

Once the body is used to burning fat instead of carbs, you are going to lose weight and burn fat because the fats stored in your body will eventually be melted away, and it will be used as fuel to keep your body functioning properly.

Keto BHB aids in this process by simply providing BHBs in your body, which is also a ketone. The more ketones you have, the more your body will adapt to utilizing fat as its fuel.

2) Quickly Puts Your Body Into Ketosis

Aside from providing added ketones to your body, Keto BHB helps in burning fat by quickly inducing ketosis compared to its normal or average rate.

Before you can experience weight loss, you must be in the state of ketosis first. However, getting into that state varies from person to person – to some, it is very fast; to others, it will take time. While it’s not necessarily bad if you take some time before you get to that state, this explains why some people can shred a whopping 12lbs in a month, whereas others may only shred half of it in the same timeframe.

Keto BHB helps in inducing ketosis by sending more BHB into your system. The more BHB you have, the quicker it can trigger your body to begin ketosis right away.

3) Can Boost Physical Performance

Exogenous ketone supplements such as Keto BHB can improve your physical performance because it provides added ketones to maintain your energy levels.

Keep in mind that you still have carbohydrates even when you are on the ketogenic diet – you’ll still want some carbs anyway because they are still important for your body to function properly.

Normally, under ketosis, your body will utilize ketones first before they go after your glucose. But if you have exogenous ketones such as what you’ll get from Keto BHB, you will have extra fuel to keep you going throughout your day.

Also, some people who follow the ketogenic diet report that they tend to be more tired than when they first started on the diet. If you are one of them, Keto BHB will help you sustain your energy levels and to help you keep going.

4) Can Boost Your Cognitive Function

If you are feeling foggy, cannot focus, or are simply mentally drained throughout your day, ketones can help you boost your focus, mental clarity, and overall brain function.

Glucose is our brain’s preferred fuel source to keep it going. However, in instances where our body lacks enough glucose to keep our brain working – such as in the case of a ketogenic diet where we lower our carb intake – our brain’s next preference is ketones. Not only that, but ketones are the type of fat that can quickly enter our brain to be used as fuel compared to other types of fats!

Okay, these are all interesting, but how can ketones improve our cognitive function?

The brain has two major neurotransmitters – glutamate and GABA. These two neurotransmitters should be balanced to achieve optimal cognitive functioning. If they are imbalanced, it can lead to problems with our cognitive state. For instance, excess glutamate and little GABA may lead to headaches, lack of focus, and anxiety.

So, what’s the role of ketones here? Ketones will help convert excess glutamate into GABA, eventually promoting a balance between the two. As the two neurotransmitters are balanced, our cognitive function will stay intact.

5) Helps In Managing Cravings

Finally, Keto BHB can help you manage your cravings to avoid excessive or overeating.

Ketones can suppress your appetite. When you are used to a diet that’s loaded with sugar, your body will crave a lot of sugar once you stop getting them. Ketones help in suppressing your appetite by somehow helping you feel fuller. Since a ketogenic diet is also relatively high in protein, and protein is also great at suppressing appetite for the same reason, this would all lead to lesser and controlled eating, thereby aiding you in burning fat and losing weight.

Is Purely Optimal Keto BHB Safe?

For the side effects, there are no associated side effects with Purely Optimal’s Keto BHB. 

So far, the only negative side that I see with Keto BHB is its limitedness – it is only limited to a ketogenic diet. Sure, some people may use it for other low-carb diets, but the results may not be as effective as if you use it for the ketogenic diet.

This is not necessarily a bad thing, though. After all, Keto BHB is designed for a ketogenic diet. Some may argue that some fat burners apply to all diets, which is true. But Keto BHB does not only aid in losing weight but in supplementing the specific needs of those who follow the ketogenic diet.
