How do I use KE4?
Starters
Many customers consume only 5 ml of KE4 daily, which amounts to about €2.15 per day. As a result, a pack of 3 can last up to 36 days. However, the average intake is twice as high. Based on the cost per effective gram, KE4 Concentrate is still the most cost-effective exogenous ketone (compared to salts, diols, or other "esters").
Advanced
Elite athletes sometimes choose a whole bottle of KE4, especially after a multi-day competition. However, such a high intake is usually unnecessary and can even hinder performance if taken during exercise. For the full deep dive, visit KetoneAid.com/Protocol.
Not for weight loss
Although it can be used to skip meals and during fasting, this product is NOT designed for weight loss. It will not burn fat for you. We recommend watching this video explaining exogenous ketosis versus endogenous ketosis, or this detailed video on why most supplements do not contribute to long-term weight loss.
Taste
The "Very Scary Cherry" flavor is an improvement over the previous "rocket fuel" flavor, but it is still very intense and tastes more like a shot of apple cider vinegar. If it's not to your liking, we recommend trying the diluted, better-tasting Ketone Shot.

Detailed information about the use and effects

The original Veech ketone ester is the king among ketones.
KetoneAid Veech Ketone Ester (also known as ketone monoester or KME) is D-Beta Hydroxybutyrate bound to R 1,3 Butanediol. This is the primary molecule used in most clinical studies on exogenous ketones and is used by 8 out of 10 Tour de France teams. It is many times more powerful and offers the best value compared to Diol, ketone salts, MCT oil, or other non-mono "ketone esters." Veech Ketone Ester – The King of Ketones. Nothing comes close.

Different ketones, different results - the real science
Beware of "fake ketones"! Many brands claim to be "scientifically proven," but they are guilty of misleading practices by hijacking the clinical results of the Veech Ketone Monoester as if they apply to their own inferior 'diol' or other ketones. Stick to the scientifically proven Veech Ketone Ester if you want to experience the results that other fake ketones only promise.
