Daily Immune Support Routine

Your immune system is not a single organ — it's an intricate network of cells, proteins, and tissues that requires consistent, daily support. The most powerful immune protocol is the one you actually do every day.
The Immune-Lifestyle Connection
Sleep, stress, movement, and nutrition are the four pillars of immune function. Chronic sleep deprivation reduces natural killer cell activity by 70%. Chronic stress floods the body with cortisol, which actively suppresses immune response. No supplement can compensate for these deficits.
Core Daily Supplements
Vitamin D3 (2,000–5,000 IU with K2), Zinc (15–30mg), and Vitamin C (500–1,000mg) form the research-backed foundation of immune supplementation. These three address the most common deficiencies in the modern diet and have the strongest clinical evidence.
Seasonal Adjustments
During high-risk periods (travel, seasonal changes, stress peaks), consider adding elderberry extract, Andrographis, and beta-glucans. These have specific antiviral and immunomodulatory properties that go beyond baseline support.
