Why I built PROTN.

As a 15 year long athlete I kept running into the same five problems with every protein on the market. So I set out to fix all of them at once.

The Struggle
  • Expensive Whey
  • Bloating & Gas
  • Acne-Forming
  • High CO2 Emissions
  • High in Harsh Metals
The YBP Fix
  • Most Affordable Price
  • No RNA, No Bloating or Gas
  • No Dairy, No Acne
  • Sustainably Produced, No Land or Animals Involved
  • Amazing flavor
People. Planet. Profit.

One mission, two countries.

In Kenya, I'm building the country's first local whey manufacturing facility, closing a gap that's kept protein imported, expensive, and out of reach for most people.

  • Kenya's first local whey manufacturing facility
  • Creating local jobs
  • Lowering the cost of protein locally
  • Reducing reliance on expensive imports
  • Building a valuable product for export

In the Netherlands, I'm introducing a still-unknown but genuinely superior protein. Affordable, with a full amino acid profile, and none of the discomfort people quietly put up with from whey.

  • An affordable protein, priced for daily use
  • Full essential amino acid profile, matching whey
  • No bloating, gas, or acne
  • No land or animal use in production

People

Kenya's first local whey processing facility creates jobs and ends dependence on expensive imported whey.

Planet

PROTN in Europe cuts CO2 emissions by 95% versus beef protein, with no land or animals required.

Profit

Every order funds both missions at once. Growing local, affordable protein production in Kenya and scaling a sustainable protein alternative in Europe.
