How is it prepared?

KÜiK is very easy to prepare: put 4 spoonfuls in your shaker, mix it with 400/500ml of water or more, shake for 10 seconds and GO! It's perfect for those moments when you can't waste much time.

When to take it?

KÜiK can be taken either punctually or regularly at any time of the day, as one portion provides all the nutrients needed for normal body function. One intake of KÜiK provides 438Kcal, which represents between 1/4 and 1/5 of the total reference calories that a normal adult takes in each day (2000Kcal). It also provides up to 128% of all the vitamins and minerals that the body needs. Therefore, the aim of KÜiK is not to completely replace what we usually call "food". It is a balanced alternative, as opposed to "junk food" or ready-made dishes that come saturated with salt and fat, which also have little nutritional value.

Can it help me lose weight?

KÜiK is designed to replace a traditional meal. It provides between 1/4 and 1/5 of the calories needed per day in a normal adult. What really helps you lose weight is the calorie deficit, that is, taking in fewer calories than your body uses at the end of the day. This is why KÜiK is a meal that can be integrated into a low-calorie diet, with the aim of losing weight.

Will taking KÜiK fill me up?

As it is known, solid diets provide more satiety than liquid ones due to the fact of chewing and having a longer digestion. However, one dose of KÜiK provides 23% of the recommended calories for a normal adult. It is a very nutritionally dense food. In addition, vegetable proteins are the nutrient most closely related to satiety and KÜiK Sport has a high content of them (27g/100g). KÜiK is a low glycemic index food, a factor that has also been linked to a higher satiety index.

Aren't liquid-based diets bad for your health?

The doubts about liquid-based diets are due to the fact that chewing is not used and this is part of the digestion process. However, the associated problems are more related to "full liquid diets" with too long periods. From KÜiK we defend the integration of our product in a normal, varied and balanced diet. Another problem associated with liquid diets is that in many cases they are deficient in fibre. KÜiK provides a good amount of this nutrient with 21g per 2000Kcal.

Can it be supplemented with other meals?

The idea of KÜiK is to substitute a meal, but you can take half of it or make 'smoothies' by mixing with fruit or other ingredients. You have some recipes in our blog!


Are all the vitamins and minerals absorbed by the body?

KÜiK's vitamin and mineral blend is designed to increase the supply of these micronutrients that may be deficient in the Western population. It is true that, depending on many factors, the absorption of these is diminished, therefore, in KÜiK there are sufficient amounts so that the vitamins and minerals are absorbed by our body in an adequate form and quantity.

Is KÜiK suitable for people with allergies and intolerances?

Yes. KÜiK Meal in its vegan range is lactose free. It is free of gluten, nuts, soya and GMO ingredients.

And for people with specific diets?

For vegans: We have a premium quality product that will meet the demands of the vegan diet.

For Flexitarians: KÜiK is suitable for Flexitarians! This means that it is for you if you follow a vegetarian diet on a daily basis, but make occasional consumption of food of animal origin.

For pregnant or breast-feeding women and children under 4 years: Consult your doctor before consumption.

What is KÜiK's glycemic index?

KÜiK has a glycemic index known as low or less than 55. This means that carbohydrates reach the bloodstream slowly, thus avoiding the known insulin peaks and providing a greater satiety effect. It also has a low glycemic index due to its mixture with fibres and proteins (see explanation 'MALTODEXTRIN').

Why the use of Maltodextrin? Isn't it bad?

Maltodextrin is a carbohydrate known for its high glycemic index and is also much easier to digest than similar ones such as dextrose. Thanks to this, it has become the main ally of high performance athletes, athletes in minor competitions and people dedicated to the world of fitness. It is found in most sports drinks, good for the health of athletes, since it is a supplement tolerated by most athletes. If taken before training, it helps improve performance in high intensity sports. If you drink it after sport, it helps muscle recovery thanks to the recovery of glycogen reserves. Moreover, thanks to KÜiK's unique formula and its manufacturing process with medical nutrition quality, KÜiK is a 100% complete food with low glycemic index, after mixing with FOS fibers that also have a prebiotic effect.

Can you take it when you're pregnant?

In principle it can, it does not contain any dangerous ingredients for pregnant women. In addition, it contains all the perfect vitamins and minerals to provide the necessary energy during this period. But we recommend that you consult your doctor.

Can people with hypothyroidism take it?

In principle it is beneficial for people with hypothyroidism, as it is rich in iodine, but we advise you to consult your doctor or nutritionist first.


Where is it produced?

In Catalonia. Production is done in collaboration with a Barcelona-based pharmaceutical company, Laboratoires Grand Fontaine, to provide you with a state-of-the-art nutritional solution.

Is KÜiK organic?

Not entirely. Some of its ingredients are of synthetic origin, but this does not mean that it is of a worse quality. In addition, organic ingredients are much more expensive, which would affect the final price of the product and would not allow us to make a food of nutritional quality and affordable at the same time.


Is it possible to buy it from abroad?

Yes. KÜiK is available throughout Europe.

Are returns accepted?

Yes, the products will be refunded or exchanged during the week following your purchase (7 calendar days, shipping costs to be paid by the customer). You can only return unused, unopened products in the same condition as when you receive them (if you were too enthusiastic when you opened the cardboard box... don't worry, you can also return it in another box!) If the packages are sent to us damaged (stained, crooked, broken, etc.), we regret to inform you that we will not be able to refund or exchange them. Also, if you are from Barcelona, you can come personally to our offices (in Calle Valencia, 287, 1º 1ª) to proceed with the return. For the refund, we will need the bank account number and the transfer will be made as quickly as possible.
