How to Follow the Immunity Boost Protocol

1

Take 5 Capsules Per Day

Take 5 capsules of Tundrex 1.1 per day for 10 days. For best results, spread them throughout the day — one capsule approximately every 4 hours.

2

Suggested Daily Schedule

Example: 7 am, 11 am, 3 pm, 7 pm, 11 pm — or create your own consistent schedule that fits your routine. Taking with food is recommended but not required.

3

Complete the Full 10-Day Course

Consistency is key. Complete the full 50-capsule box over 10 days. Do not skip doses for best results.

4

Repeat Every 3–4 Months

To stay at maximum immunity, repeat this protocol every 3–4 months. Set a reminder to ensure consistent, ongoing microbiome support.

Important: Do not take Tundrex while on antibiotics — antibiotics will neutralize the probiotic bacteria. There is no health risk, but wait until your antibiotic course is complete. Tundrex is a food supplement, not a medication, and has no known side effects.

Frequently Asked Questions

Who is the Immunity Boost protocol for?+
The Immunity Boost is ideal for anyone looking to support their daily immune function and maintain a healthy gut microbiome. It is the recommended starting point for new Tundrex users — a simple, single-product 10-day course that can be repeated every 3–4 months.
What is the difference between Immunity Boost and the other protocols?+
Immunity Boost includes only 1 box of Tundrex 1.1 — a 10-day course. The Microbiome Recovery protocol adds Tundrex 3 for a more intensive 20-day regimen. The Return to Well-Being protocol uses all three Tundrex products over 35 days for comprehensive full-system restoration. Immunity Boost is the entry-level option for ongoing maintenance.
How often should I take the Immunity Boost?+
It is recommended to repeat the Immunity Boost protocol every 3–4 months to maintain maximum immune and microbiome support. One person needs 1 box of Tundrex 1.1 per course.
Can I take more than one box at a time?+
For deeper microbiome support, we recommend upgrading to the Microbiome Recovery or Return to Well-Being protocols rather than simply taking extra boxes of Tundrex 1.1 alone. Those protocols add Tundrex 3 and/or Tundrex 4 for broader digestive tract coverage.
Does this protocol treat any disease?+
No. Tundrex products are food supplements, not medications. They are not intended to diagnose, treat, cure, or prevent any disease. These statements have not been evaluated by the Food and Drug Administration. Always consult your healthcare provider before starting any new supplement.
