KETO//OS NAT Review: I Tried Pruvit‘s Exogenous Ketones… Here‘s What Happened

Hey there, keto queen! If you‘re anything like me, you‘re always on the lookout for the latest and greatest tools to take your keto lifestyle to the next level. So when I heard about Pruvit‘s KETO//OS NAT — an exogenous ketone supplement that promises to supercharge your ketosis and accelerate your results — I knew I had to get my hands on some and put it to the test.

As a certified keto lover and biohacking babe, I‘ve tried my fair share of keto supplements and products. I‘m a big believer in the power of nutritional ketosis for fat loss, mental clarity, and overall energy. But let‘s be real, getting into ketosis by diet alone isn‘t always easy or convenient. It can take weeks of strict eating to reach that optimal fat-burning state. That‘s where exogenous ketones come in.

What Is KETO//OS NAT?

In case you‘re new to the world of exogenous ketones, here‘s the deal: They‘re basically ketones that come from an external source (outside your body), as opposed to the ketones your body produces naturally when you restrict carbs and burn fat.

The idea is that by taking these extra ketones, you can raise your blood ketone levels and trick your body into thinking it‘s in ketosis, even if you‘re not following a perfect keto diet. It‘s like a cheat code for ketosis!

KETO//OS NAT is one of the most popular and highly marketed exogenous ketone supplements out there right now. It‘s made by Pruvit, a health and wellness brand that specializes in ketone technology. The "NAT" stands for "Nutritionally Advanced Technology," which is Pruvit‘s proprietary blend of pure, therapeutic ketone salts (BHB) and other ingredients designed to optimize your performance and results.

KETO//OS NAT Benefits

So what exactly does KETO//OS NAT claim to do? According to Pruvit‘s website, the potential benefits include:

• Easy, immediate ketosis without the strict dieting
• Increased fat loss and weight loss
• Suppressed appetite and reduced cravings
• Sustained energy and focus
• Better athletic performance and recovery
• Improved GI health and digestion

Sounds pretty awesome, right? Of course, individual results can vary and Pruvit is careful to note that KETO//OS NAT is meant to support a ketogenic lifestyle, not completely replace the need for a proper keto diet.

KETO//OS NAT Ingredients

To really understand how KETO//OS NAT works, you need to know what‘s in it. The primary ingredient is beta-hydroxybutyrate (BHB), which is the main ketone body produced when you‘re in ketosis. Pruvit uses a specific type of BHB salts that they claim allows for faster absorption and more efficient use by the body.

In addition to the BHB, KETO//OS NAT also contains:

• MCTs (medium chain triglycerides) – easily digestible fats that are readily converted into ketones
• Amino acids (L-taurine, L-tyrosine, L-arginine) – building blocks of protein that support energy, mood, and athletic performance
• Minerals (sodium, potassium, calcium, magnesium) – essential electrolytes that can be depleted on keto
• Vitamin B6 and B12 – important for blood cell formation, energy, and brain health
• Prebiotic fiber (acacia gum) – helps feed beneficial gut bacteria
• Stevia leaf and monk fruit extract – natural zero-calorie sweeteners
• Caffeine (in the "Charged" versions) – for an extra energy boost

One serving of KETO//OS NAT (1 packet or scoop) clocks in at about 110-130 calories, depending on the flavor, and less than 1g net carbs.

The Science Behind Exogenous Ketones

Now I know what you‘re thinking. This all sounds very sciency and technical. Can drinking a powdered supplement really put your body into ketosis and speed up weight loss, just like that? To answer that, let‘s look at some of the research.

A 2016 study published in Frontiers in Physiology found that exogenous ketone supplements can indeed raise blood ketone levels, mimicking a state of nutritional ketosis without restricting carbs[^1]. The study participants who took a BHB supplement reached ketosis within 1 hour, compared to the 48-72 hours it typically takes by fasting or following a ketogenic diet.

Another study, this one published in the Journal of Nutrition and Metabolism, looked at the effects of a BHB ketone supplement on weight loss and other health markers[^2]. Over a 6 week period, the volunteer subjects lost an average of 7 lbs and 1 inch from their waistline. They also reported decreased appetite, reduced cravings, and improved energy and cognitive performance.

While these studies show promise for the use of exogenous ketones like KETO//OS NAT, it‘s important to note that research is still limited and most of the studies so far have been small and short-term. We need more clinical trials to really understand the long-term safety and efficacy, especially in combination with a ketogenic diet and lifestyle.

My KETO//OS NAT Review & Results

Alright, enough of the heavy science stuff. Let‘s get to the real tea: my personal experience trying KETO//OS NAT! I decided to do a 30-day experiment to see if I could notice a difference in my keto results. For context, I‘ve been keto for over 2 years and am pretty well fat-adapted, but I was stuck in a bit of a weight loss plateau.

I committed to taking 1 serving of KETO//OS NAT every morning, mixing up the flavors between Raspberry Lemonade, Maui Punch, and Swiss Cacao (the caffeinated versions). I also stuck to my usual keto diet of 75% healthy fats, 20% protein, and 5% net carbs, while also incorporating 16/8 intermittent fasting on weekdays.

Here‘s a breakdown of my observations:

• Week 1: The first few days were a little rough, not gonna lie. I definitely had some GI discomfort and loose stools (TMI, I know). But that‘s pretty common with any new supplement as your body gets adjusted. The taste of all the flavors was great though! Maui Punch was like a tropical vacation in a cup.

• Week 2: Started noticing a big difference in my energy levels, especially in the mornings. I‘m usually groggy and slow to start, but with the KETO//OS NAT I felt alert and focused right away. Was able to power through my fasting window no problem. Digestion normalized too.

• Week 3: Appetite suppression was in full effect. I had to remind myself to eat my first meal because I simply wasn‘t hungry. Noticed my ketone levels were consistently higher according to my blood tests (in the 1.5-3.0 mmol/dL range). Clothes started fitting a bit looser.

• Week 4: Energy and focus remained stable throughout the day. No afternoon slumps or brain fog. Workouts felt easier and I had faster recovery. Ended up losing a total of 4.5 lbs and 1.2 inches off my waist!

Overall, I was pretty impressed with the results. I didn‘t experience any crazy or drastic changes, but I did notice a definite improvement in my energy, ketosis, and fat loss compared to before. The appetite control was also a nice bonus and helped me stick to my fasting and keto goals.

Of course, I can‘t say for sure if these results were 100% due to the KETO//OS NAT or just a coincidence. I‘m sure being super consistent with my keto diet and workouts played a part. And I‘ve seen similar benefits from other exogenous ketones like Perfect Keto.

But I will say, the convenience and taste of the KETO//OS NAT was a big plus. It was easy to take on the go and fit into my busy lifestyle. And having the variety of flavors kept things interesting so I never got bored.

How to Use KETO//OS NAT

If you‘re thinking of trying KETO//OS NAT for yourself, here are some tips:

• Start with 1/2 scoop or packet to assess your tolerance, then gradually increase to a full serving
• Mix into 12-16oz of cold water or your favorite keto-friendly beverage
• Take in the morning and/or between meals (not too close to bedtime if caffeine sensitive)
• Use in conjunction with a well-formulated ketogenic diet and healthy lifestyle for best results
• Drink plenty of water and replenish electrolytes, as exogenous ketones can have a mild diuretic effect
• Discontinue if you experience any prolonged side effects and consult your doctor

As with any supplement, it‘s always a good idea to check with your healthcare provider before starting, especially if you have any pre-existing medical conditions or are taking medications.

Is KETO//OS NAT Worth It?

Now for the million dollar question: is KETO//OS NAT worth the hype and the moolah? Here‘s my take:

KETO//OS NAT can definitely be a helpful tool for supporting your keto journey and optimizing your results. The exogenous ketones can give you an energy boost, help control cravings, and provide some nutrients and electrolytes. It‘s super convenient and tastes great.

But — and this is a big but — it is not a magic pill or a replacement for doing the real work with your diet and lifestyle. You can‘t just slam a KETO//OS NAT drink and expect to reach all your weight loss and health goals without any other changes.

You still need to follow a proper ketogenic diet, be mindful of your calories and macros, move your body, manage stress, and get good sleep. The KETO//OS NAT should be the sprinkles on top of your keto sundae, not the whole dang scoop, if you know what I mean.

There‘s also the issue of cost. Not gonna sugarcoat it, KETO//OS NAT ain‘t cheap! Depending on how many servings you get (20, 30, or 60 packs), it comes out to around $4-6 per serving. That can definitely add up over time, especially on top of buying keto-friendly foods and other supplements.

Only you can decide if the cost is worth the potential benefits for your individual situation and goals. Maybe you‘re the type of person who thrives on novelty and likes to experiment with different products. Maybe you have a high-pressure job or athletic performance goals where optimizing ketosis could give you a leg up.

Or maybe you‘re like me, a busy mom and entrepreneur who‘s always looking for quick and easy ways to feel my best and stay on track. In that case, having a drink like KETO//OS NAT on hand can make a difference on those days when you‘re running around like a headless chicken and need a little extra oomph.

But if budget is a big concern, or you‘re just starting out on your keto and wellness journey, there are definitely less expensive ways to support ketosis, like plain ol‘ MCT oil, electrolyte drops, or even just being more strategic with your keto food choices and timing (hello, intermittent fasting!).

At the end of the day, no supplement is going to do the work for you. But if you have the means and the interest in optimizing your ketogenic experience, I think KETO//OS NAT can be a valuable addition to your routine. Just remember to always listen to your body, trust the process, and stay committed to your goals!

Final Thoughts

Whew, that was a lot of info! I hope this deep dive into KETO//OS NAT has given you some helpful insights and food for thought as you navigate your personal keto and wellness path.

As a full-time working mom and avid keto enthusiast, I know firsthand how challenging it can be to stay on track and reach your goals amidst the chaos of everyday life. That‘s why I‘m always on the lookout for tools, tips, and products that can make the journey a little easier and more enjoyable.

Trying KETO//OS NAT was a fun experiment for me, and I‘m grateful for the boost it gave me during my 30-day trial. It‘s not a permanent fixture in my routine, but it‘s nice to know it‘s there when I need a little extra support.

That said, nothing can replace the power of solid keto fundamentals, mindset, and consistency. Supplements are just that — supplementary. True, lasting health and vitality comes from nourishing your body, mind, and soul with whole foods, joyful movement, restorative rest, and aligned actions.

So whether or not you decide to give KETO//OS NAT a shot is totally up to you! But I hope that sharing my experience and insights has empowered you to make the best choices for your unique journey.
