Immunity Protocol

Updated on 22 March 2026

Preventive use

  • Phytoadapt, 3 before breakfast
  • Vita Multi, 1 after a meal
  • Trizinc, 1 before breakfast
  • Vitamin C 1000 mg TR, 1 daily after a meal
  • A probiotic, e.g. Bactiol Plus or Multibiome, 1 daily after a meal
  • Algal oil, 1 spoonful daily

Vita Multi was developed following years of clinical practice and recurring observations of micronutrient deficiencies. The formula is intended to complement the diet as part of a healthy lifestyle and healthy ageing. Nutrient needs vary according to diet, age and personal circumstances.

Treatment at the first signs of illness (start immediately)

Listed in order of priority

  • Vitamin C powder (Vitals), 1 teaspoon 3–4 times daily. Reduce the frequency as symptoms improve. The approach described uses bowel tolerance as a limit: diarrhoea indicates that the dose should be reduced.
  • Vitamin D 5000
  • N-acetylcysteine 600 mg, 1 twice daily (Optinac, Ortho-Nutrients)
  • Composor 29 (Soria), 50 drops in water three times daily on an empty stomach
  • Lactoferrin, 300 mg four times daily
  • Quercetin, 1 three times daily
  • Biomega 1000, 1 twice daily (or an equivalent omega-3 product)
  • Trizinc, 1 twice daily before meals
