Immune System

Immune Resilience

Train and balance the immune system with beta-glucan-rich medicinal mushrooms and adaptogens — for everyday resilience, not acute infection.

Prevention

Key nutrients: Vitamin D, zinc, vitamin C, selenium, glutamine, polyphenols.

Eat regularly: Oysters, brazil nuts, citrus, berries, mushrooms, garlic, ginger, leafy greens, oily fish, fermented foods.

Sleep 7–9 hours and manage chronic stress — both shape immunity more than supplements.
