Product description

The Real Science-Backed Ketones

Beware of “Fake Ketones”! Many claim to be “backed by science,” as they engage in misleading “science hijacking” – using Ketone (Mono)Ester clinical findings as if it were for their inferior ketones. Stick to the science-backed Ketone Ester if you want to experience the results of what other Fake Ketones claim.

5 Ketones: a brief history

Is a ketogenic diet required? (No)

No, it is not. Unlike the weaker Ketone Salts, Veech Ketone Ester can be used by non-Keto people.

Can anybody take it?

Not for kids and pregnant women. Seek medical advice if used outside of sport.

Can it be used for weight loss?

No. We strongly discourage people from buying ANY exogenous ketones for weight loss. None will burn fat for you, and it is not real “ketosis”. However, it may suppress your appetite.

What is the difference between Veech Ketone Ester and Ketone Salts?

Two main differences:

First, most Ketone Salts are only 50% bioavailable (only half of it can be used by the body as fuel).

Secondly, the Salts have a MASSIVE salt load, which may be fine for a week, but after which, good luck getting your rings off.

What’s the difference between Veech Ketone Ester and Diol?

Different Ketones, Different Results. Diol has a sedative-like inebriating effect, & nil to negative effect on performance. Some companies use ‘science hijacking’ (using Ketone Ester data) to confuse customers into thinking it is a performance drink.

KE4 is not a ketone salt, is naturally derived, 100% bioavailable, and is the only Ketone Ester that’s published FDA GRAS and Made in the USA. Contains no caffeine and no sugar. Ketogenic diet not required.
Taste Warning: Our “Very Scary Cherry” flavor improves upon the earlier “rocket fuel” taste, but it’s still rough and similar to cough syrup. If it’s not to your liking, we suggest trying our Ketone Shot or our Ke4 that is sweetened with sucralose. Sucralose helps to block the bitter taste much better compared to the stevia versions.
