What people say
Sweet version is the best
Sweet version is the best. Does not effect beverage taste.
I have been buying from Liquid Caffeine…
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
Adds energy without taste
I can't have caffeine so I drink decaf coffee but my husband needs the energy, so he adds liquid caffeine to his cup. It's super easy and he doesn't notice a taste difference. Will definitely buy again!

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 #1
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
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.
Great product!
I’ve been using liquid caffeine for a while now and this company never fails me. I’m especially grateful for the fact that this company ships overseas to military addresses. Shipping is fast and the product does its duty.
Tasteless, works well
I love that this product is affordable, tasteless, and versatile. I don’t like that the company uses ai for their images, recipes, and I’m sure more. I also wish there was a way to track the order through the website.
I’m a first time buyer from this…
I’m a first time buyer from this company. Comparing this company to the company that I usually purchase from, the price was a little less, delivery was pretty quick, and I was happy with the product.
I like the ease of ordering, the loyalty points and periodic discounts, and the quickness on receiving my order.
I like the ease of ordering,
Very good if you like energy drinks
This is a Great product
This is a Great product! I've been using it for 12 years! It allows you unrivaled flexibility with my caffeine regiment!
