Why mix pea, soy and sunflower when one plant protein would be cheaper?
Because each one has a gap in its amino acid profile that the other two fill. Vegan 3K Protein Banana from nutri+ blends three isolates into one powder and turns 30 g into a creamy banana shake.

Protein contributes to the maintenance of muscle mass
An authorised EFSA claim that applies to this powder as a source of protein. Protein also contributes to the maintenance of normal bones. One shake after training delivers a substantial share of the day's protein in a form that needs no cooking.

Soy isolate, pea isolate, sunflower protein: nine essential amino acids covered
Legume proteins are rich in lysine but short on methionine. Sunflower seed protein brings the sulphur-containing amino acids that legumes lack. The blend lists all nine essential amino acids, from histidine through to valine, with leucine leading at 6.8 g per 100 g.

1 kg pouch, 33 servings, three heaped tablespoons each
Sweetened with sucralose rather than sugar, free from aspartame, lactose and gluten. Shaken into 300 ml of water or plant drink, the isolates dissolve without grit. Banana is one of the many flavours in the 3K range.
Anyone who eats plant-based and lifts weights has done the maths at some point. Lentils, tofu and oats add up, but on a hard training day the protein column still comes up short. A shake would solve it, if only most vegan powders did not taste of raw pea and leave a chalky film on the tongue.
The 3K approach tackles both problems at once. Soy protein isolate forms a mild, neutral base. Pea protein isolate adds lysine and arginine. Sunflower protein rounds off the profile where legumes run low. Isolation strips away most of the fat, fibre and carbohydrate, which is why 83 % of the powder is protein and a serving carries just 111 kcal. What remains is a fine powder that behaves in a shaker the way a dairy-based one does.
The brand behind it is a small German company from Grafschaft near Bonn that calls itself a "100 % Vegan Company" and sells nothing of animal origin. The packaging speaks seven languages, the recipe stays the same in every flavour: three protein sources, flavouring, sweetener, and not a single filler.

📋 Recommended intake
Pour 300 ml of liquid into a shaker and add 30 g of powder (about 3 heaped tablespoons). Shake well until the powder is completely dissolved. Athletes should consume the 3K protein after the workout. We recommend a plant-based drink.

Trade name: Instant powder for the preparation of a protein-rich drink with sweetener.
Ingredients: Soy protein isolate, pea protein isolate, sunflower protein, flavouring, sweetener (sucralose).
Net quantity: 1000 g / 2.2 lb (33 servings of 30 g)
Where does 3.0 g of salt per 100 g come from?
Nobody adds salt to this powder. The figure is calculated from sodium (sodium × 2.5), and sodium occurs naturally in soy and pea protein isolates as a leftover of the extraction process. Per 30 g serving that works out at 0.92 g of salt, roughly what two slices of bread contain. Worth knowing if you track sodium, irrelevant for most.
Is 1.0 g of methionine per 100 g enough for a "complete" protein?
Methionine plus cysteine are the limiting amino acids in most plant proteins. Here the two add up to 2.4 g per 100 g of powder, which is about 2.9 g per 100 g of protein. The FAO reference pattern for adults asks for 2.3 g. So the blend clears the bar, and it does so mainly thanks to the sunflower component. That is the practical reason for the third "K".
⚠️ Mandatory information: Contains soy. The nutrient content of the raw materials is subject to natural fluctuations. When preparing with a plant-based drink, please consider its additional nutritional values. The salt content is exclusively due to the presence of naturally occurring sodium. Filling level is due to technical reasons. After filling, air escapes, causing the powder to lose volume.

💬 Frequently asked questions
-
Does it taste like most vegan powders, sort of grassy and gritty?+
The grassy note comes from pea protein on its own. In this blend pea is only one of three components and soy isolate provides a neutral base, so the banana flavouring takes the lead. Texture-wise the isolates are fine enough to dissolve in a shaker; with a plant drink the shake turns noticeably creamier than with water.
-
Can I switch from whey to this without losing out?+
The EFSA claim "protein contributes to a growth in muscle mass" is tied to protein as such, not to its source. What matters is the amount per serving and a complete amino acid profile. A 30 g serving brings 25 g of protein and all nine essential amino acids, including about 2 g of leucine. Lactose is not part of the recipe.
-
I have a soy allergy. Is there a version without soy?+
Not this one. Soy protein isolate is the first ingredient and therefore the largest share. The nutri+ range at Viterna includes protein powders built on other sources; the overview is linked below.
-
Why sucralose instead of stevia or plain sugar?+
Sucralose (E 955) is around 600 times sweeter than sugar, so a trace is enough to sweeten a full shake. That keeps sugar at 0.4 g per serving and leaves the calories to the protein. It also carries none of the liquorice aftertaste some people notice with stevia. Aspartame is not used.
-
Do I have to drink it straight after training?+
The "after the workout" advice is aimed at athletes. If you simply use the powder to reach your daily protein on busy days, breakfast or an afternoon shake works just as well. It is a food, not a supplement with a fixed dosing schedule.
