I have been buying from Liquid Caffeine for over a year now after unsuccessfully trying other brands and I have to say Liquid Caffeine is by far the best Caffeine additive out there. They are prompt in getting the product to me, never any mistakes, the product itself is good and their customer service is among the best. I definitely recommend this company for your purchase

Bad taste. One man's opinion!
Response from Liquid CaffeineFeb 24, 2026
Socal Guy we are sorry you didn't like our Liquid Caffeine, but we feel like 1 star is unfair. We know it is bitter. That is why we recommend adding it to a drink. We have intentionally kept it as pure of caffeine as possible, which means it will have the bitter flavor of caffeine. If you want something that tastes good on its own, we are afraid Liquid Caffeine is not for you. But if you to be able to add caffeine without all the other chemicals to any beverage easily than Liquid Caffeine is for you.

Customer service has always been top notch. I had a couple questions and Ben F. responded well within 24 hours and provided the tracking number I needed and answered my other questions. And as always, the Liquid Caffeine is great. I've never had an issue with the product. It's the clean energizing caffeine I've come to know and love.

The product is great and priced well. My first order I only got the vitamin B thinking it also had caffeine in it, so had to make another order for the actual liquid caffeine. That could have been more clear on the site, but overall I'm satisfied and will order again in the future.
