What is a functional drink?

A functional drink is a ready-to-drink beverage that delivers a specific nutrient on top of hydration: L-carnitine, protein, electrolytes, carbohydrates or guarana. No powder, no shaker: the dose is already in the bottle or can.

Every QNT drink lists its composition per serving, so you know exactly what it provides. For the most popular family, drinkable protein, our protein drinks guide compares the formats in detail.

L-carnitine drink: ready to drink and sugar-free

L-carnitine is a compound the body makes from two amino acids, lysine and methionine. It is found mainly in meat. As a drink it needs no preparation, so it fits into your day or around your training.

L-Carnitine 2000 mg comes in a 700 ml bottle, sugar-free, in four flavours. L-Carnitine Water, in 500 ml, adds vitamin D, zinc and selenium, which contribute to the normal function of the immune system. It is also sugar-free and vegan.

Before training: a ready-to-drink pre-workout

Kick Pre Workout comes in a sparkling 250 ml can: caffeine from guarana, anhydrous caffeine and beta-alanine, with no sugar. Its caffeine content is high, so it is not recommended for children or for pregnant or breastfeeding women.

For a lighter format you can also enjoy outside the gym, Energy Collagen combines guarana, matcha tea and collagen in a sugar-free sparkling drink.

During exercise: electrolytes, BCAAs and carbohydrates

During your session, Electrolyte Water provides electrolytes in a sugar-free sparkling water, in a 330 ml can.

For long sessions, two 700 ml bottles take over: BCAA 8000 mg, with branched-chain amino acids in a 2:1:1 ratio and no sugar, and Carbo Load, a carbohydrate drink with caffeine, designed for prolonged efforts.

Drinkable protein: Protein Water or Protein Shake

Two styles of protein drink. Protein Water from the QNT LIIFE range is clear and sparkling: 12 g of protein with collagen per 330 ml can, sugar-free. Protein Shake is creamy: 25 g of protein in 330 ml, closer to a snack.

Protein contributes to the maintenance of muscle mass. Every format sits together in the Protein drinks collection.

How to choose your functional drink?

The simplest way is to start from the moment: before exercise, Kick or Energy Collagen; during, Electrolyte Water, BCAA 8000 or Carbo Load; after, Protein Shake or Protein Water; every day, an L-carnitine drink.

To compare every QNT drink in one place, the Drinks collection gathers the whole ready-to-drink range.

Frequently Asked Questions

Your health and results are our top priority. This FAQ answers the essential questions about QNT products, so you know exactly what you’re buying and how they support your goals.

What is a functional drink?

A functional drink delivers a specific benefit beyond hydration: protein for muscle, caffeine or guarana for energy, electrolytes around training, or collagen. At QNT, every ready-to-drink option is built around one clear function, with the amounts per serving stated on the label.

Which functional drink should you choose for your goal?

Start from your moment: Kick Pre Workout or Energy Collagen before training, Electrolyte Water during exercise (BCAA 8000 and Carbo Load for long sessions), Protein Shake or Protein Water afterwards, and an L-carnitine drink every day. Compare the product pages: the amount per serving is always stated.

Do QNT drinks contain a lot of sugar?

It depends on the type. Protein waters like Protein Water and Iso Whey are light and low in sugar, while carbohydrate drinks like Carbo Load are deliberately high in carbs to fuel effort. Always check the sugar value per serving on the label and pick according to your goal.

Can you drink a protein drink every day, even on rest days?

Yes. A protein drink is first and foremost a source of protein, useful day to day and on rest days to reach your needs. Just count it within your daily protein total, the same way you would a meal or a snack.

Does a protein drink replace a meal?

No. A protein drink completes your diet, it does not replace a balanced meal, which also brings fiber, vitamins and minerals. Use it as a snack or a backup when a protein-rich meal is not an option, and keep real meals as the foundation of your day.
