The sports drink for during and after exercise

- Rick, 21 September, 2025

Several isotonics used, but I like this one best in terms of taste and quantity.

Ideal complement to water

- Jan, 16 August, 2025

When cycling, especially in hot or cold weather, you find that isotonic drinks are much more palatable than water. And you immediately supplement part of your energy needs. Easy to modulate using the measuring spoon, just shake the bottle and go. To refill the water bottle on long rides, it would be handy if it was also available in 1-portion sachets or effervescent tablets.

Pros & Cons

Easy to prepare
Sugars and salts you need
Difficult to take with you on the bike

Feels good

- Nelus, 13 July, 2025

Have tried them all. Of the 3 flavours, I like the orange the best. The red fruit tastes like soap. The lemon is too present for me. Felt good with it during the Bartje200.

Pros & Cons

Drink away easily.
Falls well on the stomach.
Orange flavour is fine.
Red fruit tastes like suds.

Great thirst quencher
No gastrointestinal complaints

I say . buy !

- Mient Heidema, 25 April, 2025

As an avid athlete, I am always looking for ways to improve my performance and properly support my body during and after an intense workout. This isotonic sports drink really surprised me in a positive way! What I noticed first was the taste - refreshing, not too sweet, and easy to drink away during exercise. No sticky or artificial feeling, just a nice thirst quencher. But what really matters is the effect. The drink clearly helps replenish lost electrolytes and keeps my energy levels stable, even during long sessions. I feel noticeably less exhausted afterwards and recover faster. Also nice: no stomach upset, which sometimes happens with other sports drinks. All in all, a top product that does what it promises. Highly recommended for both recreational athletes and serious athletes!

Been using the lemon (yellow) flavour for some time. Fine in itself, but I really recommend the new (red) flavour. Drinks down a lot better.

The new (red) variant really comes highly recommended.

Very good iso drink

The tastiest (for me)

- René, 26 May, 2024

Used some powders but always come back to this one. Depends on the effort but I always put 1 1/2 scoop on eem 750 ml bidon. Packaging is too small though, and thus a lot of waste. Refill packaging in vacuum bag would be desirable

Pros & Cons

Dosing scoop too wide
No refill as loose packaging

- Dylan, 9 December, 2023

Very tasty sports drink high in carbohydrates in the right proportions. For light workouts, I do 1 scoop and for very hard long workouts 2 scoops per water bottle.

+-40 grams of carbs per scoop

Good flavour!

Great energy drink at a competitive price.

- Remco, 9 December, 2023

Great product that is not inferior to similar (but more expensive) competitors' products. If you stick to the package's recommended mixing quantity, it will probably be an even better energy drink but then your teeth will flee out of your mouth, so sweet. Halving the quantities is enough. (Still a matter of taste of course)

Pros & Cons

Affordable
Can last longer than the packaging indicates
Too sweet in the recommended quantity

Solid sports drink, good value for money

- Jos, 13 September, 2023

Powder dissolves well, no lumps like some other powders. The small size of the jar also ensures that it runs out before it starts clumping in the container. Seems to hydrate well while cycling. Only downside is that as with all powders, you have to dig for the measuring scoop first.

Pros & Cons

Convenient size
Dissolves well
Digging for the measuring spoon on opening

Super isodrink

- Nicklas, 30 July, 2023

I've recently tested all of mantel's energy products. Mostly because the price was super competitive compared to the other brands, but also because I generally love mantel, so I thought it was worth a try. I was definitely not disappointed! This iced drink has become a regular part of my workouts. It's easy to drink. It tastes really good and provides just the right amount of energy for my long runs. In conjunction with their bars and gels, you are well prepared for adventure!

fresh isotonic thirst quencher as a supplement of necessary 'quick' energy

- Robert, 27 April, 2023

I have been using this house brand for several years to my complete satisfaction. During a day of XC mountain biking I often put up to 3 liters of water with just a pinch of salt in my Camelback, in addition I take 2 750ml water bottles with this isotonic drink and a few cubes e/o granola bars. The sweet and sour grape sugars of this Mantel drink do their job well, do not get boring in terms of taste and drink away nicely. The price is also a lot friendlier than that "hi-tech" astronaut stuff from more expensive competition, while the nutritional value of this private label product is often the same or even better. Therefore, always 'apples-to-apples' thoroughly compare ingredient labels before blindly believing sports marketing or sponsored 'pro' influencers. ;) This isotonic house brand 'powder' remains for me, qualitatively and favorably priced, the 'best' choice for now. Highly recommended in short.

Pros & Cons

good complementary fast sugars/ carbs
good thirst quencher
Good value for money
sour-sweet tastes fresh
sticky

Great Taste for a reasonable price, advice buy them by the five!

- Robèr, 20 February, 2023

Just an excellent sports drink with good value for money. With the possibility to buy them per 5 even 10% cheaper. A full scoop is a fine amount for me for a 750 ml water bottle.
