THE IMMUNE COLLECTION
IMMUNE 101
Your immune system has two layers. The innate arm (NK cells, macrophages) responds within minutes — fast and general. The adaptive arm (T-cells, antibodies) takes days but is precise and remembers. Most immune nutrients support the innate arm first, because that's where daily resilience lives.
Vitamin D is the single most clinically supported immune nutrient — most immune cells carry D3 receptors. Zinc drives healthy T-cell production. Vitamin C provides antioxidant protection for immune cells and powers their function. AHCC® activates natural killer cells. Medicinal mushrooms (reishi, shiitake, maitake) supply beta-glucans that prime innate immunity. These are the non-negotiables.
There's a difference between keeping your system primed (daily foundational support — D3, zinc, AHCC) and responding fast when you feel something coming on (elderberry, echinacea, higher-dose botanicals). The daily stack is insurance; the rapid stack is intervention. Most people need both, layered.
