Rez Energy Drink review + coupon code -10%

Rez Energy Drink has removed all of its discount codes. The code ALU10 is no longer available, and there are no promotional offers to apply before checking out.

If you want to pay less, the best option right now is Holy Energy. It is a energy drink powder with an excellent value for money, fast shipping in France, and offers that are still available.

I'll share my opinion with you anyway on Rez Energy Drink !

My opinion on Rez Energy Drink

Rez Energy Drink is a energy drink powder, sugar-free, no artificial colors and low-calorie, which relies on natural flavors to give you a real energy boost without the usual crash you get from traditional energy drinks.

I received the packets in September and tried several flavors before writing this review. The first positive point, even before tasting it: it’s a product Made in France, in a certified laboratory FSSC 22000. Production, warehousing, and offices are all located in France.

Each dose is prepared in a shaker with approximately 500 ml of water. One packet equals one dose. The formula contains natural caffeine, of the vitamins and minerals, for a gradual release of energy and a low number of calories per dose. No sudden crash at the end of the day, which is rare for this type of product.

It's also a drink that's suitable for gaming as in the sport the caffeine promotes focus and stamina, without the excess sugar found in traditional canned drinks.

My thoughts on the package

The package is compact, with minimal packaging. The product arrives in recyclable cardboard, which reduces waste. No complaints there.

My thoughts on the different flavors

The The powder dissolves very well in water. Of all the flavors tested in the shaker, there's never any sediment left at the bottom after shaking. Here are my tasting notes, one by one.

Taste Rez Cherry

First taste test cherry, diluted in 500 ml of water to shaker. The result is clear and distinct: it really tastes like cherries. My rating: 8/10.

Taste Rez Strawberry & Kiwi

Taste strawberry and kiwi It blends the two flavors well. I'm still more of a fan of the cherry, and the strawberry note isn't my favorite, so I'll give it 7/10. But to each their own: try it out for yourself and let me know what you think in the comments.

Taste Rez blackcurrant & raspberry

the blackcurrant and raspberry is a nice surprise. I was a little skeptical when I saw the powder, but the taste is really good and the scent is great. My rating: 9/10.

Taste Rez original

Taste original is the most neutral in the line. A good choice if you prefer a subtle flavor profile without any fruity notes.

Taste Rez Bubble Gum

the bubble gum is the most polarizing in the lineup. Try it out based on your preferences.

Taste Rez Mango and Passion Fruit
