A Good Offering From V8
Flavor Name: Peach Mango, Size: Pack of 6 (8 Fl Oz)
It's no secret that I'm a fan of the V8 energy drinks. This is a six-pack of 8-fluid ounce cans of V8 energy in the flavor duo of peach and mango. Out of all the V8 energy drinks, it's probably my second favorite behind orange/pineapple. It's easy to find and can also be found in a 12-pack on occasion.
V8 falls under the Campbell's brand. There are 80mg of caffeine in each can of V8 energy. This is about equal to most cups of coffee. I've found when I drink one can to get started in the morning that I have a nice energy boost that allows me to get my morning routine going.
The temptation I have to resist is to have too many of these. The cans are smaller and they have such a deceptive, smooth taste that it's easy to forget that you're actually getting a fair amount of caffeine. Too much caffeine is definitely not great and I find it really messes with my digestive system. So, this is definitely a drink I enjoy in moderation.
The peach and mango duo has a nice balance to it. It lacks the spark of the orange/pineapple, however, it tastes substantial and I always feel like I'm getting a solid drink when I have one of these.
V8 Energy has definitely gone up in price during the pandemic and some of the flavors can be hard to track down, however, I pretty consistently see peach/mango. While the price has gone up, it's still less expensive than nearly anything in the energy drink category except for the cheap stuff that isn't at all healthy.
This energy boost comes from green tea and it's just a smoother energy boost without all the jitters and without a sugar crash.
There are 50 calories in each can and each can actually counts as one serving of fruits and veggies.
Overall, I'm a definite van of the V8 energy brand and Peach/Mango is my second favorite flavor duo. I get the boost I need, however, it's healthier and more evenly spread out without giving me the caffeine crash that I hate. While I have to drink these in moderation, when I need an energy boost the first place I'm going to look is at these V8 energy drinks.

Hands down best drink ever!
Flavor Name: Peach Mango, Size: Pack of 12 (8 Fl Oz)
The Peach Mango V8 is genuinely one of my favorite drinks ever. I honestly love these more than coffee or any caffeine drink I get from drive-thrus. I’m not a huge fan of carbonated drinks, so this is absolutely perfect for me. I’m actually the type of person who lets pop go flat before drinking it (yes, I know that’s weird 😂), so having something flavorful without carbonation is amazing.
It has the same fruity, energy-drink type flavor that drinks like Bubblr or Alani have, just without the sparkling part. The peach mango flavor is so good and refreshing, and I always keep these stocked at home.

Great combination of veggies and fruits
Flavor Name: Peach Mango, Size: Pack of 6 (8 Fl Oz)
Thanks Amazon for making this drink affordable. I was buying it from Walmart which was pricey. This is my go to drink in the mornings after drinking water. The energy I feel all morning while I am at work. No jittery feeling, I was diagnosed being pre-diabetic. This drink is perfect for me. I get to drink my veggies and fruit.

GREAT GRAPE FLAVORED AND INCREASED ENERGY
Set name: Welch's Grape
I have tried the competitor’s grape flavored versions.
This is by far the best grape flavored energy drink.
It gives you the increased energy level you’re looking for without making you feel “fidgety.”
Highly recommend this energy drink for its effectiveness and flavor!
