How & Why Ketones Work

  • Pruvit ketones drink is a dietary supplement that provides the body with exogenous ketones. This drink is designed to help your body maintain ketosis, or a state in which the body burns fat for energy, rather than carbohydrates. To use Pruvit ketones drink, mix one scoop of powder with 8-10 ounces of cold water. Consume this drink twice daily, preferably before or after exercise.

    There are many benefits of ketosis and KETO OS NAT:

    Fat-Loss: KETO OS NAT targets and burns body fat with every serving by positioning your body to follow a proven, accepted, and universal fat-loss formula.

    Appetite Suppression: Ketones naturally suppress your appetite allowing you to make better choices and eat less frequently.

    Protect and preserve muscle: Ketones are extremely anti-catabolic (they are protein/muscle sparing) and will preserve and protect your lean tissue during periods of caloric restriction.  The more muscle you preserve, the more fat you burn.

    Fast & Sustained Energy: Ketones offer fast energy that maximizes your mindset and mental focus while motivating you to move more, do more, and be more.

    Improved Clarity & Focus: KETO OS provides a cleaner, quicker energy pathway than glucose while providing very important signaling molecules to the body.

    Joint Mobility: Ketones, specifically beta hydroxybutyrate found in Prüvit’s Proprietary Technology, help maintain healthy joint mobility.

Ketone FAQ's

How often can I take exogenous ketones?

Exogenous ketones can be taken multiple times a day depending on the outcome you want to achieve. Follow the specific directions printed on each product for the recommended daily dosage. If you do experience any side effects after introducing exogenous ketones into your diet, consider reducing your daily dose by half and increasing your water consumption. As symptoms subside, slowly return to the full dose.When first introducing exogenous ketones into your diet, start by taking them in the morning to allow your body to make use of the ketones without the presence of other fuels like sugar. If you want to do a second dose, we recommend taking additional ketones in the afternoon when you start to feel your energy dip, or before you enter a workout to optimize your performance.

Is KETO OS NAT® Dairy Free?

Yes, KETO OS® NAT™ is both dairy and gluten free.

What are BHB Salts and where do they come from?

BHB is found in nature in many foods including eggs and milk. Salts are acids and bases bound by ionic bonds. Salt is a chemistry term used to describe a specific type of chemical compound. Technically, they are defined as ionic compounds formed by the neutralization of an acid and a base. They consist of positively charged and negatively charged components, which typically dissociate in water or water-based solutions (such as blood). In lay terminology, we call table salt, which is actually sodium chloride (NaCl) “salt,” but it is just one of many chemical compounds which are defined as salts. The “BHB salt” is simply a compound that consists of sodium (Na+), potassium (K+), and the ketone body β-hydroxybutyrate. In the Keto OS product package, these individual components are being held together by ionic bonds; however, when you eat the product, it is absorbed into the blood where it dissociates into free Na+, K+, and BHB since it is a water-based solution. Thus, consuming the product directly and immediately puts ketones into your blood.Ketones are naturally slightly acidic, so the combination of BHB with sodium acts as a bit of a buffer to this acidity. Ketones will also naturally act as a diuretic, so you lose salt, potassium calcium and magnesium, and it is generally encouraged to increase sodium intake with ketones. The addition of sodium to the product will replenish this salt loss.


Yes, our KETO OS NAT® is vegan friendly as we use naturally fermented ketones and amino acids.

What are ketones and what is ketosis?

Ketones, B-hydroxybutyrate (BHB), acetoacetate (ACA), and acetone, are molecules made in the liver from the breakdown of fats. This typically only happens when you’re following a very strict high fat and low carbohydrate diet, or fasting. When insulin levels are low and glucagon and ephine levels are relatively normal, fat is released from fat cells and travels to the liver. Here, ketones are produced and used as an alternative to glucose as energy to fuel the body. Nutritional ketosis is the process of your body breaking down fat as a source of fuel and creating ketones. Supplementing with exogenous ketones like KETO//OS® introduces ketone bodies into your bloodstream without pushing your body into nutritional ketosis, allowing you to experience a range of health benefits.

What Is The Source of Caffeine?

Caffeine Hydrous.

Why is there sodium in KETO//OS NAT®?

Prüvit’s Pure Therapeutic Ketones® in KETO OS NAT® need to be bound to something in order for the body to absorb and utilize them. Prüvit uses a combination of the minerals sodium, calcium, and magnesium to bind to BHB ketone salts, and a higher percentage of sodium specifically because sodium is absorbed very rapidly by the body. Those sodium-bound ketones get into the bloodstream faster, and the body can reach a state of ketosis faster! Calcium and magnesium are absorbed at a slower and steadier rate, resulting in the more sustained ketone utilization and benefits your body experiences after drinking KETO OS NAT®.

Why would I take KETO//OS®?

Supplementing with exogenous ketones allows you to optimize your human potential and experience the whole-body benefits of ketosis, without having to follow a restrictive ketogenic or low carb diet which can be very difficult to adhere to.
