I drink protein practically every day, especially after training, when I do not have time to make a proper meal straight away. Here what convinced me most was the formula - it is short and there is no whole list of additives that I do not need anyway. I have vanilla and it tastes very good both with water and with milk. It is not overly sweet and I do not get that heavy feeling I used to get with other supplements. The 26 g of protein per serving is just right for me too. The only minus is the scoop - it holds 20 g and a serving is 30 g, so you have to remember that extra half.

I buy protein fairly regularly, so I have been through quite a few different products. Here the formula is the main plus: short and with nothing unnecessary. I am not keen on supplements that have half a label of various additives, and here it really is simple. The flavour is very nice too. I have vanilla and it is delicate, it does not hit you with an artificial aroma and it is not overly sweet. That makes it easy to drink every day without getting bored. It dissolves in water without a problem, and with milk it is delicious.

For you if:

  • you find it hard to get enough protein from food across the day
  • you are cutting
  • after training you have no protein meal at hand

Protein contributes to the growth and maintenance of muscle mass. A 30 g serving gives 26 g of protein, and there are 30 servings in a pack.

Who it is for

When it makes sense

  • You find it hard to get enough protein from food across the day.
  • You are cutting: a serving has about 110 kcal and 0,3 g of fat.
  • After training, at work or travelling you have no protein meal at hand.
  • You want a short ingredient list: five items on the label.

It makes no sense if food already gives you the protein you need, or if you are allergic to milk proteins.

It is a pity I only found this protein now. It really does have only the essential ingredients (I counted five) and it tastes great. I drink it with oat milk or lactose free cow's milk. Strawberry suits me best, it has little pieces of freeze dried fruit.

Highly recommended! Top quality products with a clean formula and on top of that very tasty, with no heaviness or stomach ache like with other protein supplements.

The formula of these supplements is first class as always. I definitely recommend the chocolate flavour, which is the best protein of all the ones available on the market :)

Sebastian· verified purchase

God, thank you for this protein. The first one I actually like the taste of <3 It does not have that artificial taste. Ameeezing

Sonia

Strawberry is very nice, especially in porridge, because in a shake the pieces do not dissolve that well.

The price is not the lowest, but with a formula and quality like this it is OK for me.

Szymon

After other proteins I sometimes had a heavy stomach, here I do not have that problem.

The chocolate flavour made with milk tastes like cocoa from a well known brand.

A very good protein, especially if you do not like overly sweet supplements.

Good to know before buying

Have a question?

WPI is whey protein isolate, and WPC is concentrate. An isolate usually has a higher share of protein and less lactose and fat. Compare the table for the specific flavour: the share of the raw material in the formula is not the same as the percentage of protein in the finished product.More in the guide (in Polish): Czy potrzebuję odżywki białkowej? WPI kontra WPC, smak i laktoza

No. The supplement makes it easier to top up protein, but eggs, fish, meat, dairy and pulses also deliver other nutrients. You choose WPI for convenience, not as a replacement for the whole value of food.More in the guide (in Polish): Ile białka dziennie? Rachunek z jedzenia i odżywki

Chocolate contains reduced-fat cocoa. Vanilla goes well with porridge and yoghurt. Strawberry contains freeze-dried fruit. Pick the flavour you like and check the nutrition table for that variant.More in the guide (in Polish): Czy potrzebuję odżywki białkowej? WPI kontra WPC, smak i laktoza

WPI gives no immediate effect once you drink it. It helps deliver protein when your menu is short of it. Changes in strength and muscle mass also depend on training, energy in the diet, rest and time, and we do not promise a particular number of weeks.More in the guide (in Polish): Okno anaboliczne: czy trzeba pić białko zaraz po treningu?

A serving holds 0.3 g of sugars (chocolate), so there is little lactose. The product contains milk, so it is not suitable with an allergy to milk proteins.

Show all questions (17)

Yes, 250 to 300 ml of water or milk. With milk the serving has more calories and protein than the table shows.

30 servings of 30 g. The scoop in the pack holds 20 g, so a serving is 1.5 scoops.

Yes. You can buy every product on its own, without a bundle and without the survey. A bundle is the easier choice when you want the timings written out and the whole plan in one basket.

Amounts and servings come from the product label. Statements about what the ingredients do rest on the list of claims authorised in the European Union, and sports schedules on the publications named next to the sentence. The batch test report covers the tested sample, not how well the product works.

Measure out 30 g. How many scoops that is, check the marking on the scoop in your pack.

Both work. With milk the serving has more calories and protein. Pick what you tolerate well.

As many as your food is short of, within the product instructions. For some people one serving is enough, and some do not need the supplement at all.More in the guide (in Polish): Ile białka dziennie? Rachunek z jedzenia i odżywki

No. The first 30 minutes after training change nothing here. What counts is the daily amount of protein and how you spread it across meals.More in the guide (in Polish): Okno anaboliczne: czy trzeba pić białko zaraz po treningu?

Yes, to porridge, yoghurt or a smoothie. Count that serving towards your daily protein.More in the guide (in Polish): Ile białka dziennie? Rachunek z jedzenia i odżywki

If your food is short of protein. A training day alone does not settle it.

The 2017 ISSN position stand gives 1.4 to 2.0 g per kilogram of body mass a day for people who train. The higher range, 2.3 to 3.1 g/kg, applies to a cut and to fat-free mass. You count protein from food and from the supplement together.More in the guide (in Polish): Ile białka dziennie? Rachunek z jedzenia i odżywki

The isolate has less lactose than a concentrate, but it is not lactose free. Check the label of your flavour. With an allergy to milk proteins the product is not suitable.More in the guide (in Polish): Czy potrzebuję odżywki białkowej? WPI kontra WPC, smak i laktoza
