Vilgain
7% Off
Limited time deal
Why we love it
100% natural premium protein.
Grass-fed free-range cows.
Excellent taste and digestibility.
Main Highlights
The first protein of 100% natural origin: premium protein powder made from high-quality ingredients without additional frills. It is rich in highly usable protein, including BCAAs that support muscle growth and retention.
From the milk of free-range cows: the cows are fed with grass for at least 10 months a year. As a result, it has a cheaper fatty acid composition than the milk of cows that receive compound feed.
Maximum ease of use: Whey protein has a similar bioavailability to meat and is therefore best suited for the human body. It has excellent digestibility and contains a high proportion of essential amino acids.
Good macronutrient ratio: Our protein powder has less than 125 kcal per serving, is naturally protein rich and contains little sugar and fat*, making it a great aid for a simple, high-quality protein replenishment.
Natural sweetener from stevia leaves: the stevia plant allows us to produce a high-quality sweetener with steviol glycosides. They have no effect on blood sugar levels, are 200-300 times sweeter than sugar and are considered a safe calorie free sweeteners for our whey protein powder. Note: measuring spoon not included
