What are exogenous ketones?

Ketone bodies are our body's best sources of energy, especially for muscles, brain and organs! They can positively influence inflammatory processes in a natural way via the immune system. Your sleep is deeper and more restful.

The ketone products, Keto//OS NAT, are the only exogenous ketones in the world, produced by natural microbial fermentation of plants and only from dextrorotatory BHB's. That's why we're proud to offer a nearly 100% natural energy source that's made vegan, gluten-free, and dairy-free.

Artificially produced additives are avoided. In addition to the three macronutrients protein, carbohydrates and fat, the exogenous ketones can be described as the fourth macronutrient that provides large amounts of energy.

How do I take exogenous ketones?

A truly delicious drink

At the beginning it is advisable to slowly get used to the ketones. Therefore, an amount of only half a sachet per day is recommended for the first 2-3 days. This can be taken in the morning or in the afternoon. Feel free to use one of the colorful bags that contain caffeine (charged). The white sachets are without caffeine (caffeine free) and are recommended in the late afternoon or in the evening.

It is best to dissolve the powder in 0.4 - 0.5 liters of cold water. If it is still too sweet for you, you can dilute it further with water. Make sure to stir the powder well or better use a shaker.

Since it is not easy to cut the sachet in half, it is advisable to dissolve the whole sachet in 0.8 - 1 liter of water and then cut it in half. You drink half (within 15 - 30 minutes), the other half you can keep in the fridge until the next day without hesitation.

For those who are struggling with a somewhat sensitive stomach / intestines, it is advisable to proceed as follows for another 2-3 days:

Take half a sachet in the morning (with caffeine) and half a sachet in the afternoon or evening (without caffeine). Once the stomach / intestines have gotten used to it, you can increase to a whole sachet in the morning as well as in the afternoon or evening.

After this time, the majority of users take one sachet in the morning and one sachet in the evening. With caffeine in the morning and no caffeine in the evening.


It makes sense not to eat carbohydrates for at least 1 - 1.5 hours before taking it. Especially no sugar. The same goes for 4 - 5 hours after ingestion. This causes the body to start using its own body fat. You should also drink a lot during this time. Water or tea is best, but coffee is also allowed - but without sugar (exceptions: stevia, erythritol, xylitol). Gladly with some cream.

For the athletes among you:

It is best to dissolve a sachet in approx. 0.5 - 1 liter of cold water 30 minutes before exercising and drink half before training. The other half during training - this gives you more focus and more power.

For regeneration, ketones without caffeine can be taken after a workout or before going to bed to optimize sleep.


If your stomach / intestines are sensitive, please do not drink the exogenous ketones all at once, but allow about 15 - 30 minutes before starting the workout. Please remember that your body needs to get used to it.
