What’s Really in the Flavor? Understanding the Natural Flavors in KETO//OS® NAT

Natural Energy, Naturally Flavored

If you're someone who pays attention to what you put in your body (which we are guessing you are), you’ve probably asked: “What do ‘natural flavors’ in ketones actually mean?”

It’s a fair question—and an important one.

When it comes to our KETO//OS® NAT products, we’re committed to transparency wherever possible, while still protecting the integrity of our proprietary formulation. Let’s walk through what we can share and what makes our flavors both natural and trusted.

First, a Quick Note on Our Formula

Our KETO OS® formulation is a proprietary asset of Prüvit, and we take that responsibility seriously. Because of this, we are not able to release vendor or supplier information or specific formulation details, as these are part of our confidential and protected proprietary blend.

That said, we want you to feel confident and informed about what you're drinking—and why quality matters.

Natural Flavors You Can Trust

Every Pruvit flavor is crafted using natural sources, meaning the ingredients used to create both flavor and color come from:

  • Real fruit and vegetable juices

  • Plant-based essential oils

  • Other botanical sources

✅ No synthetic additives
✅ No artificial flavoring
✅ No chemical-based coloring

This means when you're sipping on your favorite flavor—whether it's Raspberry Lemonade, Splash, or Tru Passion—you’re not getting hidden additives that counteract your health goals.

Manufacturing You Can Feel Good About

Every batch of KETO//OS NAT is manufactured in a facility that is:

  • cGMP certified (Current Good Manufacturing Practice)

  • FDA compliant

  • Uses Standard Operating Procedures (SOPs) for quality and consistency

  • Has robust Quality Control systems in place

This isn’t just marketing fluff—it’s industry-leading compliance and safety protocols that protect the product and ultimately, protect you.

Third-Party Testing for Every Batch

Every single batch of KETO//OS NAT goes through rigorous testing before it reaches your shaker bottle. That includes:

  • ✅ Heavy metal testing on all raw materials

  • ✅ Heavy metal testing on all finished products

  • ✅ Microbial analysis to ensure cleanliness and purity

  • ✅ Certificates of Analysis (COA) issued for each batch

This level of scrutiny ensures that what you're putting into your body meets the highest standards for purity, safety, and performance.

Why This Matters

There’s a lot of noise in the supplement space—and plenty of low-quality imitations that use synthetic flavors, cut corners on testing, or hide behind vague labels.

At Prüvit, we believe that you deserve better.
Better ingredients. Better flavor. Better standards.

And while we may not disclose every single vendor or percentage of our blend (to protect the uniqueness of our proprietary product), we’re proud to give you a product that delivers clean fuel with total integrity.
