FAQ / KG1 Nutrition – Frequently Asked Questions

What makes KG1 Nutrition Protein special?

KG1 Nutrition stands for radical simplicity:

❌ no sucralose

❌ no aspartame

❌ no acesulfame K

❌ no xanthan gum

👉 Instead: agave syrup powder & a hint of stevia

👉 Result: natural taste without artificial aftertaste

In short: Fewer ingredients. More honesty.

How does protein without artificial sweeteners taste?

Unlike what you might be used to – and that's precisely the advantage.

Our protein is:

  • lightly sweetened
  • natural in flavor
  • not overly sweet

👉 No artificial "candy flavor," but a shake you can drink every day without ever getting tired of it.

Is protein without sucralose better tolerated?

Yes, protein powder without sucralose is often better tolerated – especially by sensitive stomachs.

Why does KG1 Nutrition not use sucralose, aspartame, and xanthan gum?

Because we are convinced: A good product doesn't need artificial additives.

Many conventional proteins contain:

  • artificial sweeteners for extreme sweetness
  • additives for consistency

👉 We deliberately take a different approach:

clean, reduced, and transparent

Can protein powder be heated, boiled, or fried?

Yes – and this is exactly where KG1 shows its strength 👍

Our protein is perfect for:

  • Pancakes
  • Porridge
  • Kaiserschmarrn (shredded pancake)
  • Baking recipes

👉 Many protein powders with sweeteners like sucralose can develop an off-taste when heated

👉 KG1 remains even when heated:
natural in taste – without an artificial aftertaste

Who is KG1 Nutrition suitable for?

For everyone who:

  • consciously wants to avoid artificial additives
  • is looking for a clean protein without unnecessary extras
  • values natural taste over excessive sweetness

👉 Whether for everyday life, sports, or conscious nutrition

Is the protein sweet enough, though?

Yes – but consciously lightly sweetened.

If you're used to heavily sweetened shakes, KG1 may taste milder at first.

👉 Many appreciate exactly that after a short time – because it's more natural and pleasant.

Why "less is more"?

Because we believe a good product doesn't need tricks.

👉 fewer ingredients
👉 more transparency
👉 better feeling

KG1 Nutrition is not an overloaded fitness product.

It's protein in its most honest form.
