Immune Support Stack

A defense-oriented stack combining micronutrients that are commonly deficient in modern diets with botanicals that prime innate immunity. The core trio of vitamin C, D, and zinc addresses the most frequently studied immune-nutrition gaps. Botanical adjuncts add polysaccharide-based immunomodulation. This is maintenance-level support — not a treatment for active illness. Individual responses and needs vary.

• vitamin-c

  500–1000 mg/day in divided doses

• vitamin-d3

  2000–5000 IU/day; test serum levels and adjust

• zinc

  15–30 mg/day with food; avoid chronic high doses

• elderberry

  500 mg extract daily during high-exposure periods

• beta-glucans

  250–500 mg/day

• echinacea

  300–500 mg extract; most studied for short-term use at onset of symptoms
