Why KGI Nutrition exists

We often faced the same problem:

Many products taste artificial, contain unnecessary additives, or are full of intense sweeteners that are neither natural nor well-tolerated.

That's why we decided to do it better:

Products that are honest.
Products that are naturally sweet.
Products that truly taste good.

With the premise "Plant-based sweetness, full flavor," we developed unique whey, vegan, clear vegan proteins, and EAAs – sweetened exclusively with agave syrup powder and stevia.

What makes our products special

Our food supplements are exclusively manufactured in Germany according to our specifications – to Swiss quality standards and free from artificial:

  • Sweeteners
  • Flavors
  • Colorants
  • Fillers

Instead, we rely on natural sweetening, high-quality raw materials, and a convincing taste – without compromise.
