I’ve been enjoying using the liquid caffeine product. It’s easy to dispense from the pump bottles and mixes in well with my electrolytes in the morning. Customer service is GREAT.

I've been purchasing from Liquid Caffeine for several years, and the product is always consistent. Their website is glitchy, but it gets the job done.

Five stars forever and always. I learned about Liquid Caffeine from a local, mobile coffee truck here in 'Podunk', FL that made their own energy drinks; I will never forget his selfless act of sharing... See more

Excellent caffeine source instead drinking energy drinks or energy powders or pills that would make you sick.
I like how it is versatile to blend in with any liquid. I even tried mix it with straight water and it didn't change how the water taste.

I have been a loyal customer for 7 years and they rock. Always fast shipping and the product amazing. I put in my water bottle in the morning. Perfect amount of pick me up. Highly recommended. You can't taste it and two pumps approximately two cups of coffee in the caffeine content. Great product

Longtime customer
I need caffeine to counteract medication side effects. I don't like coffee. LC, which I've been utilizing for more than a decade, is the perfect solution

15 Years of Flawless Service
I've been using Liquid Caffeine since 2010—nearly every day—and the service has been just as dependable as the product. Orders are always well-packaged and arrive on time. On the rare occasion there’s an issue (like a burst bottle), they fix it immediately, no questions asked. Over the years, they’ve even sent me thank-you extras for being a loyal customer. It’s rare to find a company this consistent, responsive, and genuinely customer-focused after so many years.

Reply from Liquid Caffeine
Kym we are really sorry that we gave you the impression the caffeine levels in our Liquid Caffeine has dropped. We would like to reassure you we are putting the same quantity of caffeine in our Liquid Caffeine as before. We merely changed the labeling to reflect the fact that the dosage isn't always exactly the same due to a number of variables.

Keeps me awake when not even prescription meds will.
I have narcolepsy and even 2 strong amphetamines don’t work to keep me awake. It is awful. But 2 squirts of liquid caffeine in my 6:30 pm cup of coffee will keep me awake until bedtime at 10 pm. May not seem like a lot to you but to me it’s a life changer. Thank you!
