What is the Keto OS Nat?

The Keto OS NAT is a new keto supplement that brings ketones into your body far and beyond many other competing ketone supplements. In order to understand what all that means, let’s break down the process.

Ketosis is a state that your body naturally falls into when it burns fat for energy or when it enters light starvation as a result of a lack of glucose. Ketones are made in the liver during this process and they force your body to focus on burning fat for fuel instead of carbohydrates. This is the primary weight-loss process relied on by keto diets.

Keto supplements, therefore, add additional ketones into your body and nudge it into burning more fat. They generally also have the helpful side effect of lessening your appetite or helping you retain muscle.

The Keto OS NAT supplement uses ketones that are really similar to ones made by your body naturally during normal ketosis. This helps the fat-metabolizing process happen faster and more smoothly, theoretically making you lose weight more readily and consistently.

What’s in Keto OS NAT?

Keto OS NAT, like other ketone supplements, uses a series of ketone molecules and other ingredients to metabolize fat and help you lose weight. The ingredients list listed by the manufacturer is:

  • Caffeine: this is a little stimulant to help you workout and wake up.
  • Erythritol: this sweetener helps make the supplement taste better when you consume it.
  • Fermented L-Leucine: this amino acid can’t be made by your body but is usually consumed by food. Its presence here helps you build muscle.
  • L-Taurine: this amino acid also helps build muscle tissue.
  • BHB, or R-Beta Hydroxybutyrate: this regulates blood ketone levels. It helps you metabolize fat.
  • C-Med 100: this helps you repair DNA and regulate white blood cell level, although there’s not a huge reason for it to be included in a ketone supplement.
  • Rebaudioside A: This is another sweetener, much more potent than the erythritol.

It comes in a few flavors, too: swiss cacao, raspberry lemonade, and orange dream are just a few.

What Does Keto OS NAT Do, Exactly?

Basically, Keto OS NAT delivers BHB in the form of a salt into your body. Ketones are naturally made by your body during regular ketosis, which is only experienced when carbohydrates are not present in healthy amounts for your body to consume as fuel.

Ketone supplements introduce ketones into your blood without the natural lack of nourishment, causing your body to think that it’s in ketosis.

Your body then starts to burn fat as a result, making more ketones along the way. Your body uses the fat for energy and, in theory, you can maintain a regular diet or follow a ketone body and lose weight effectively.

Your workouts will be a little more effective and consistent as a result since your body’s proteins aren’t being consumed for food instead of carbs, and the protein supplements included in Keto OS NAT are designed to boost your workout effectiveness, as well.

Since the BHB is produced by your body in natural ketosis states, it’ll be absorbed quickly and without any side-effects or other issues.

The benefits are best experienced when you’re following a traditional keto diet, as well, since these types of diets will help you keep a healthy body while you reduce your carbohydrate intake over time.

What’s Different About it from Keto OS and Keto OS Max?

The difference is minimal and seen in the BHB composition. Keto OS doesn’t use fermented BHB ketone bodies, which supposedly makes the BHB harder to be absorbed by the body quickly.

Keto OS Max, on the other hand, includes more amino acid chains that can help you work out longer and with more focused concentration. Your fatigue is reduced as a result of Keto OS Max consumption.

Apart from these two supplements, Keto OS NAT’s major differences can be seen where its amino acids focus on muscle building and stamina and improving your immune response through the inclusion of C-Med 100.


Safety and Side Effects

Ketone supplements such as Keto OS NAT may be accompanied by side-effects commonly seen alongside the ketogenic diet as a whole. Ketosis is a state that the body enters in times of nutritional peril, remember. As a result, your body may burn through water and certain minerals more quickly than normal.

To counteract this, drinking more water and eating mineral-rich food is recommended.

If the event that you become dehydrated or don’t consume enough vital minerals, such as sodium, magnesium, and potassium, you may develop flu-like symptoms such as headaches, cramps, fatigue, dizziness, and diarrhea.

Decreasing the amount of Keto OS NAT you are consuming should eliminate these problems over time.

Overall, Keto OS NAT is safe for most people to use as long as they are vigilant about remaining on their ketogenic diets and consume plenty of water and vital minerals.

Is the Hype Worth It?

Keto OS NAT is a fantastic keto supplement that really does help you burn body fat much more quickly than you might otherwise. That being said, it’s also very similar to other ketone dietary supplements and is especially close to its cousin products.

Is it worthwhile? In our opinion, it’s a great supplement through and through and is particularly effective if you’re already interested in a ketogenic diet. However, you may be able to find cheaper ketone supplements that can give similar results with the same lack of side-effects. There’s no doubt that Keto OS NAT is one of the better choices if you frequently workout, as well, due to its included amino acids.

Finally, if you do not practice a strict diet or follow a ketogenic diet as a whole, you may find it difficult to keep any weight lost from Keto OS NAT off your body over the long term.
