Product Details

Highly Concentrated Pure Soy Protein

100% Plant-Based

Health, general well-being, climate change, and animal welfare are driving more and more people toward a plant-based lifestyle. At Prozis, we are committed to helping you reach your fitness goals, whether you're following a vegan diet or just exploring different options.

Made exclusively from soybeans, each 30 g serving of Prozis 100% Soy Protein (unflavored version) delivers:

  • 25 g of protein
  • 1.5 g of carbs
  • 0 g of sugars
  • 0 g of saturated fat

It also provides a complete amino acid profile with naturally occurring branched-chain amino acids (BCAAs)—Leucine, Isoleucine, and Valine—to fuel your body.

"It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable."
Socrates, 469-399 BC
A great addition to your healthy diet

Most plant protein powders aren't complete, meaning they don't contain optimal levels of all the nine essential amino acids. Soy protein powder is one of the few exceptions. It's a complete protein source that provides all the amino acids your body cannot produce and needs to obtain from food.

Protein
Why does it matter?

People need significant amounts of protein daily to ensure a normal growth and maintenance of muscle mass, which is not only important for its aesthetic appeal but also, and foremost, for supporting overall wellness.

Moreover, protein plays a crucial role in the maintenance of normal bones, which provide the foundations for a strong, healthy body.

For what?

Many vegetables and cereals make excellent protein sources. However, soy stands out in terms of quality, amino acid profile, and digestibility. Prozis 100% Soy Protein was developed to complement your daily protein intake in a very convenient, healthy, and tasty way.

For whom?

100% Soy Protein by Prozis is a high-quality vegetarian protein source, developed for just about everyone who leads an active lifestyle and is looking to increase the amount of protein in their diet.

Whether you're an athlete with specific protein requirements, follow a vegetarian or vegan diet, or simply want to cut back on animal products, 100% Soy Protein by Prozis is the healthy, delicious, and complete protein you need.

With Prozis 100% Soy Protein, not only will you be fueling your fitness goals with high-quality vegetarian protein, but also truly enjoying every sip of your shake. There are several flavors to explore—try them all and choose your favorite!

How to prepare

Add 1 scoop (30 g) to 350–400 mL of water or vegetable drink in a shaker and shake well. Should you prefer a creamier consistency, add the same amount to a bowl and gradually add 30 mL of water or vegetable drink while stirring vigorously.

the best vegan proteins - vanilla

I didn't think they'd surprise me so much! Excellent vanilla-flavored vegan protein. They dissolve really well, especially in whipped soy milk, delicious, or in porridge... really good! Excellent vegan alternative!
