Monster Zero Sugar is one of those rare drinks that actually delivers on the promise of big flavor without the crash. It hits with that classic Monster punch—bold, crisp, and just the right amount of bite—yet somehow stays clean, smooth, and shockingly light. For anyone who wants the energy without the syrupy heaviness, this is the gold standard. What really stands out is how balanced it tastes. Most zero‑sugar drinks feel like they’re trying too hard, but Monster Zero Sugar just works. It’s refreshing, it’s consistent, and it’s the kind of drink you can grab at 6 AM or 6 PM and know exactly what you’re getting. I do wish they’d take one extra step: swap the regular sodium for sea salt. It’s a small change that would make a huge difference for people watching their blood pressure. Sea salt tends to be gentler and less processed, and it would open the door for even more folks to enjoy this drink without worry. Still, as it stands, Monster Zero Sugar is a powerhouse—clean energy, great taste, and a dependable boost when you need it most.

I have been drinking these for years.

I don't like sugar-free stuff, but for the sake of not gaining a lot of weight, I have been drinking these for years. I like them. People say that energy drinks are bad for you, but as I said, I have been drinking them for about 10 years now, or more. I am 60 years old.

I used to drink Bang but unfortunately Bang has 300 mg of caffeine whereas Monster only has 160 mg. I drink coffee in the morning too so I felt better after I switched to less caffiene. Dont get me wrong, caffeine is my best friend but too much was making me deficient in potassium and magnesium which is horrible for your heart health.

Great when it’s set to right temperature and

When coke is at it truest formula and tastes it’s amazing. But it doesn’t take much to totally destroy the whole thing. I don’t know if it’s clear plastic bottles in the sun stripping it of its taste and carb” DELICIOUS BUBBLES” if they are flat might as well throw away the whole batch

The gateway

As I enter my 10th year of advanced caffeine addiction I applaud the White Monster Zero as the beverage I choose to fuel my addiction and dependency. I have tried the other leading brands. I’ve even tried one of the white versions of the zero sugar brand from another manufacturer and still keep coming back to monster the Marlboro of energy drinks. So thanks again, monster for making the most addictive taste like a dry sweet tart carbonated magic that helps me face this ever so flawed world that we live in. Cheers.

It's just that good

I love this flavor most of all. I went from drinking the Monster Mango Loco and the other flavors and have tried most of all other Monster's at one point until I tried this flavor of the zero Monster and I've liked it since. It's light ,crisp , refreshing and has a good light not too overly citrus-like taste. I really like that it has no sugar-free aspartame saccharine aftertaste or that twangy diet taste like anything zero or sugarless usually either has or lacks in other ways or you can tell just by that particular taste, but not in this Zero Sugar Monster. The taste is so good I don't feel like anything is missing etc. I don't mind it's zero sugar at all and I choose this instead of my usuals with it now because i like this flavor so much that I get this now every time and keep plenty in my fridge it's always a must have on my shopping list %26 has become 1 of my faves. I recommend if you like light ,crisp, refreshing citrus type of flavors and the Monster kick of energy , it's on point %26 just that good.

The Azle TX store needs to keep more on hand. I go through 5 twelve packs a week. so when I go grocery shopping I usually have to go to two places to get my a week supply because the Azle Walmart only stocks restocks these once a week and they only stock like 14 to 16 twelve packs for an entire week. It is the most sold monster everywhere. so stock up on them instead of planned parenthood supplies because it's obvious that no one is buying that crap.

A Tournament Weekend Must!

These are a must-have for our road trips, especially during busy tournament weekends! They give us the boost we need to power through those long drives home after a full day or weekend of games. They’re also great for those early mornings when everyone is a little sluggish — a few sips helps get us moving and ready for the day ahead. The taste is solid, and they’re super convenient to grab and go. We always make sure to have a few on hand for travel weekends!

Tasty and Not Sweaty!

Great taste for Zero Sugar. Caffine content on point. 200 mg per can. More expensive than competitors but competition makes me sweat if I drink two. With Monster I can drink and stay dry!

About a neutral as you can get

Great citrus flavor that quenches my thirst %26 boost to keep me going. Plus, it is about neutral as you can get for someone who's never tried it before.
