What is the Immunity bundle for?

The Immunity bundle is designed to support your natural immune defenses and help you maintain performance during periods of higher strain - during intense training, stress, travel, or during challenging seasonal periods.

Why combine vitamin C, D3 + K2, and zinc with copper?

These micronutrients complement each other:

  • Vitamin C contributes to the normal function of the immune system and helps reduce fatigue
  • Vitamin D3 + K2 support immunity, proper muscle function, and bone health
  • Zinc contributes to the normal function of the immune system, and copper helps maintain mineral balance with long-term use

    Together, they form a balanced everyday foundation.
Who is the bundle suitable for?
  • Athletes and active individuals
  • People exposed to higher physical or mental stress
  • Anyone who wants year-round immune support
  • Ideal during winter or demanding training blocks
Can I take the bundle every day?

Yes. The Immunity bundle is intended for daily, long-term use, as long as you follow the recommended dosage.

Can I combine the bundle with other supplements?

Yes, we designed our product portfolio so the individual products can be freely and meaningfully combined based on your needs and goals.

Thanks to the well-thought-out formulas, the supplements don’t unnecessarily overlap, but instead complement each other functionally, so you can safely include them in your everyday routine.
