Pruvit KETO OS NAT Review: Honest Take

Recently, I started experimenting with a ketogenic diet in an effort to reduce my appetite by emphasizing low-carb foods and limiting decadent desserts like cake.

I discovered Pruvit’s KETO//OS NAT during my investigation; it had a delicious cheesecake flavor and promised to satisfy those needs without going overboard. So of course, I had to give it a shot. Not sure if it met my expectations or not?

I will be reviewing Pruvit KETO//OS NAT soon, so that should provide the answer. But before we get started, let’s take the time to learn a little bit about the company that created this unique keto shake.

About the Brand

Leading the way in the field of ketogenic nutrition is Prüvit’s KETO//OS® brand, which is renowned for its premium ketone supplements that promote ketosis—a metabolic state in which the body burns fat for energy.

Their products provide an efficient and effective approach to entering and staying in ketosis, with benefits ranging from improved mental clarity and physical performance to weight management. They are built with an emphasis on bioavailability and Nutritionally Advanced Technology.

With a wide variety of tastes and a helpful community, KETO//OS has made a name for itself as a reliable source for people looking to benefit from the ketogenic lifestyle.

KETO//OS NAT Nutritional Breakdown

Based on the company’s website, this ketone drink is formulated with exogenous ketones that allow you to optimize your human potential and experience the whole-body benefits of ketosis without following a restrictive ketogenic or low carb diet, which can be difficult to adhere to. Let’s dig down into its nutritional breakdown and key ingredients list.


According to the product label, 1 Ampoule of KETO//OS NAT packs 35 calories, which is pretty darn reasonable, especially if you’re all about that keto lifestyle. See, the ketogenic diet is all about going low on those calorie counts, and this right here fits the bill nicely. And if you’re looking to supercharge your energy with this drink, just remember to match it up with the calories your body’s craving.

Main Macros

Watching your macros carefully when following a ketogenic diet is crucial, especially when it comes to carbohydrates. The key to this diet is to cut your carbohydrate intake significantly and replace it with fats in order to activate your body’s fat-burning process. Speaking of macros, the 4g of carbohydrates in the KETO/OS NAT may seem reasonable to some people. However, it’s a good idea to pair this drink with low-carb side dishes like crisp green salad, stir-fried veggies, or sautéed spinach.

The worst part is that, despite what its labeling suggests, this blend doesn’t include a significant amount of protein or fat. This is in contrast to some other excellent keto drinks available. This implies that to maintain your ketogenic lifestyle, you must ensure you’re eating plenty of protein and healthful, fat-rich foods.

Key Ingredients

Let’s take a closer look at the ingredients list of this shake to determine its relevance to your keto diet plan.

Max NAT Blend

According to the product description, this ketogenic drink mix has an outstanding lineup in its Max NAT Blend, including fermented leucine, L-arginine, L-taurine, and KetoNAT (R-Beta Hydroxybutyrate). Let’s dissect it now: By using R-Beta Hydroxybutyrate, you may be able to gently encourage your body to produce more ketone bodies. Conversely, adding amino acids to your diet, such as L-Arginine, L-Taurine, and Fermented L-Leucine can be extremely helpful to your body’s ability to assemble and rebuild proteins.

Vitamins Minerals

In addition to having mixes with Max NAT Blend KETO//OS NAT is packed with vital vitamins and minerals that your body longs for, such as 5 mg of Vitamin B6, 100 mcg of vitamin B12, 245 mg of magnesium, 880 mg of sodium and 170 mg of Calcium.

According to studies, increasing your intake of vitamin B complex may be the key to improving your mental health in general and assisting you in reducing anxiety and managing stress. [1] Adding electrolytes like sodium, calcium and magnesium may help boost your fluid intake. [2]

My Pruvit KETO//OS NAT Experience Story

As someone on a personal ketogenic journey, I was eager to see how Pruvit’s KETO//OS NAT Swiss Cacao flavor would fit into my lifestyle. With all the talk of this drink helping with ketone production and potentially assisting in weight loss, I was excited to give it a whirl.

First off, the Swiss Cacao flavor was a delight to the taste buds. It offered a rich and satisfying chocolatey experience, making it feel like a genuine treat rather than just a supplement. I couldn’t complain about that!

But when it came to its impact on my ketone journey, my experience was a bit different. While I did notice an initial boost in my ketone levels after consuming the drink, it didn’t seem to provide any magical weight loss results. However, I must note that the keto journey is highly individual, and what works wonders for one person might not yield the same results for another.

What I did appreciate was the sustained energy I felt after consuming KETO//OS NAT. It helped me stay focused and alert throughout the day, which was a significant plus. However, I didn’t experience any remarkable changes in my weight.

In the end, my Pruvit KETO//OS NAT Swiss Cacao experience was a mixed bag. While it didn’t exactly propel my weight loss efforts, it did contribute to my overall sense of well-being and provided a tasty addition to my keto routine. As with any dietary supplement, it’s important to remember that individual results may vary, and it’s crucial to maintain a balanced diet and active lifestyle for sustainable weight management.

Final Thoughts

In the end, Pruvit’s KETO/OS NAT did find a place in my daily routine, even though it may not have been a miracle weight loss answer for me. But I want to address that the best way to manage weight is to combine regular exercise, a well-rounded, balanced diet, and customized solutions based on each person’s unique needs and objectives.
