1–2 g/day |
Vitamin D |
Maintenance of functional and structural integrity of mucosal cells in innate barriers |
2000 IU/day (50 µg/day) |
10,000 IU during few weeks, followed by 5000 IU (until 25–hydroxyvitamin D concentrations rise above 40–60 ng/mL (equivalent to 100–150 nmol/L)) |
Vitamin E |
Maintenance of functional and structural integrity of mucosal cells in innate barriers |
15 mg/day (RDA) |

Selenium |
Differentiation, and functioning, of innate immune cells |
50 µg/day |
Up to 200 µg/day |
Zinc |
Maintenance of functional and structural integrity of mucosal cells in innate barriers. |
Men: 8 mg/day |
Zinc lozenges: over 75 mg/day administered within 24 h (divided into 6–8 doses, each separated by 2–3 h when awake) |
Iron |
Maintenance of functional and structural integrity of mucosal cells in innate barriers |
Men: 8 mg/day |
Ferrous iron salts (ferrous sulfate and ferrous gluconate): 60 mg Fe/day (taken with food to avoid gastric discomfort) |
Omega-3 fatty acids (EPA + DHA) |
Conversion to specialized pro-resolving mediators (SPMs) such as, protectins, resolvins and maresins to relieve the inflammation and enhance lung injury |
250–300 mg/day of EPA + DHA |
1500–3000 mg/day EPA + DHA |
Multivitamin supplements including vitamins (A, B6, B12, C, D, E and folate) and trace elements (Zn, Fe, Se, Mg and Cu) |
Support of the cells and tissues of the immune system overall |
Supplying nutrient requirements according to the 100% RDA for age and gender |
