Kill Cliff Review - 14 Things You Need to Know

Kill Cliff is a sports drink that aims to keep users hydrated before and after extreme workouts. The website for the drink claims that the drink keeps you “hydrated and energized while you sweat” by offering “slow-release carbs, essential electrolytes, and no junk.” We have reason to doubt the claim that all of the ingredients are beneficial to the user.

Also, we doubt the company’s claim that you can instantly recover from a workout just by drinking the beverage. Our research team has looked at all of the product’s so-called natural ingredients and determined whether trying the drink is worth your time or money. To help you see the truth, we offer our findings here.

Kill Cliff can be purchased through their Official Site.

What is Kill Cliff?

Kill Cliff is a company that sells energy drinks and recovery bars. Sports or energy drinks often provide us with essential nutrients and a caffeine punch.

Kill Cliff produces and markets recovery drinks and protein bars for use as part of a nutritious lifestyle and regular exercise.

Kill Cliff claims to have helped athletes push harder, faster, longer, and provide hydration and sustained energy levels without crashes or spikes.

It has been aiding bodybuilders and fitness warriors to recover from vigorous exercise with a fresh post-recovery energy supplement drink for many years – or so they say. This is what some of the research has to say about these kinds of products:

How Did Kill Cliff Start?

Todd Ehrlich, who was a Navy SEAL, founded Kill Cliff. Ehrlich saw the need for sports drinks that would taste amazing, along with giving out fantastic energy.

kill cliff created by navy seal

After years of research, he came up with a formula that wasn’t just a blend of water and sugar (what most energy drinks are like) but contained a unique formulation of electrolytes, vitamins, enzymes, and specific extracts: green tea, ginger root, and ginseng root.

Ehrlich continued to look for a variety of new ways to help consumers aid their workouts. In 2017, the company launched a second product line, Endure, rich in essential electrolytes and a low glycemic carbohydrate level.

The slow-release carbohydrate fuel results in a sustained glucose supply and helps promote the oxidation of fats for energy during workouts.

It also doesn’t contain any artificial flavors or colors.

The products Kill Cliff sells include:

  • Endurance Drinks in blood orange and berry punch flavors
  • Recovery Drinks in a variety of flavors
  • Apparel and gear include backpacks, hoodies, shorts, sports bras, tees, tanks, hats, and socks.

Kill Cliff Claims

A few claims the company makes about Kill Cliff include:

kill cliff claims

  • It helps the body recover immediately from a sweaty workout.
  • Contains electrolytes, vitamins, enzymes, and a few herbal extracts, including ginger root, ginseng root, and green tea.
  • Alternative to other sports drinks, sodas, or juices.
  • Contains no artificial flavors, sweeteners, or colors.
  • Non–GMO.
  • Has no sugar or agave.
  • Gluten-free.
  • Dairy-free.
  • Contains only 15 calories per can.

Although this product claims to boost energy and the recovery process, it is best to do so naturally. According to Dr. Dugarte, “…this can often be done with little more than some mild caffeine (coffee, tea) + fruit before a workout, followed by lean protein and complex carbs afterward.”

Additionally, if you have consistent energy and recovery issues, you should consult with your physician to discuss other, safer options.

Simultaneously, it helps boost metabolic rate, thus assuring energy generation that maintains optimal stamina and enhances focus.


Caffeine helps improve alertness when a person is fatigued and feels drowsy and lethargic. It also causes the blood vessels to open up by allowing blood to flow.

The ingredients for digestive health include a special formula that aims to help you get the most from your post-workout meal. The ingredients include:

  • Glucuronolactone – a precursor for the ascorbic acid synthesis
  • Lipase – breaks down fats in the digestive system.

Kill Cliff Alternatives

kill cliff alternatives

Kill Cliff vs. Red Bull

Red Bull’s target consumers tend to be fans of extreme sports, party animals, and younger people.

Every eight ounces of Red Bull contain 27 grams of sugar, compared to zero for Kill Cliff, which they market that it’s like drinking orange or apple juice. However, the difference is that fruit juice has some nutritional value despite its high amounts of sugar.

Kill Cliff vs. Monster

Monster also markets to younger people, extreme sports fans, and professional wrestling fans. Monster’s official website doesn’t even contain its ingredients, and it’s easy to see why: each 16oz can of Monster has a whopping 54 grams of sugar on top of guarana and caffeine.

Kill Cliff vs. 5-Hour Energy

In sharp contrast to Red Bull and Monster, 5-Hour Energy’s target audience are coffee drinkers. However, this energy drink has had links to reports of bad health cases, and its directions read like a pharmaceutical label.

The difference is that the FDA doesn’t regulate energy drinks, nor are there any clinical studies about them.

What Users Are Saying

What Users Are Saying

“Great product for recovery, will keep buying.”

“They’re great. But anytime I drink one I have muscle cramps later. I don’t know what’s causing them. I tried hydrating better. That didn’t seem to matter.”

“While this tastes like Cherry Limeade mixed with a 9 volt battery, it does THE JOB in being a WAKE UP and get things done drink. Compared to other KILL CLIFF products which taste much better and not as harsh when you drink them. The fact you aren’t suffering from the Caffeine “Jitters” or have a “HARD CRASH” afterwards is a nice change from other energy drinks. It’s more like drinking around 2-3 Triple Espressos in a row; then going to work. The energy is straight and steady for around 6-8 hours without a huge energy drop at the end; just more like I think I need a 20 minute nap in the car and then I’m good for the rest of the day. I usually take a post-work nap and then go home and do about 3-5 more hours without feeling like I’m AMP’d up when I go to sleep either.”

Bottom Line

The Bottom Line on Kill Cliff

Before you pop the top on a Kill Cliff, here’s our final verdict. We like that we found some favorable customer comments and a few natural ingredients like caffeine and green tea. However, we’re skeptical about this one because no clinical research proving the supplements will boost energy levels or improve recovery. We also have concerns because customers were talking about ineffective ingredients and side effects.

If you want to boost your energy levels, we suggest going with a program that can help you keep track of your health goals and lose weight for good.

Among the best weight-loss systems we’ve researched this year is Noom. We love that the program offers individual coaching, customized meal plans, interactive support groups, and tons of other health tracking tools.

Also, the makers of Noom are offering all of our readers a free trial offer, which is even better!
