Top News: SOUDAL QUICKSTEP CYCLING TEAM ANNOUNCES PARTNERSHIP KETONEAID Press Release

Update Feb 5th 2024: Full inventory available in the US.

EU now has all Ke4 in stock. EU customers please do not exceed 35 characters in your street address, or there will be a 3-day delay. 

Our top seller is Ke4 Pro, featuring a super-concentrated formula with 50% Ketone Ester. It can be optionally diluted in a splash of cold water.

3 Sizes: (Subscribe and Save 10%, USA & Canada only)

  • 3 x 60ml concentrated small bottles. $90 (90g of KE, $1/g) 
  • 12 x 60ml concentrated small bottles. $355 (360g of KE, $0.97/g)
  • BULK 36 x 60ml concentrated small bottles $999 (1,080g of KE $0.93/g) 
  • New limited release Ke4 with Sucralose Bulk 36 set. $750. Tastes better. Details here. Available in US & EU only.
  • Trial pack with 1 Ke4, 1 Ke1 and 1 SnakeWater 100ml $45 (not available in the EU) 

Many customers consume as little as 5ml of Ke4 daily, about $2.50 a day. Therefore, a 3 pack can last up to 36 days. However, the average intake is double this amount. On a per effective gram basis, Ke4 is more cost-effective than most non-racemic ketone salts.

Elite athletes might opt for a full bottle of Ke4, however, such a high intake is typically excessive and could even hinder performance. For further details, refer to our video featuring a pro rider that used much less.

Disclaimer: This product is not designed for weight loss and will not burn fat for you. We recommend watching this video explaining exogenous ketosis vs endogenous ketosis or this extended video on why most supplements don't contribute to long-term weight loss.

The "flavor" is called "Very Scary Cherry". It no longer tastes like rocket fuel when slightly diluted. It still doesn't taste like OJ, but more like cough medicine. Most are fine with it. If not, try our diluted, better tasting,

Our "Very Scary Cherry" flavor improves upon the earlier "rocket fuel" taste, but it still is very rough and more reminiscent of cough syrup. If it's not to your liking, we suggest trying our diluted, more palatable,  Ke1 drink or our delicious  Ketone Water. Compare Ke4 to KE1 and SnakeWater. 

*This Ketone Ester is a Ketone Monoester, a bond of D- Beta Hydroxybutyrate and R 1,3 Butanediol. It's the primary molecule utilized in 90% of exogenous ketone clinical trials.
Other ingredients: Water, Allulose (non-GMO zero glycemic all-natural sweetener), Stevia, Natural Cherry Flavors, Potassium Sorbate (freshness). (Does not contain Taurine)
