Micronutrients & recovery

Restoring deficient micronutrients (Vitamins A, C, D, E, B2, B6, B12, folic acid, iron, selenium, zinc) to recommended levels improves immune function and increases resistance to infection.

If you suspect you are deficient in key immune-supporting nutrients (like Vitamin D, Zinc, or Vitamin C), getting your levels checked and restoring them to the recommended range is a proven way to support your immune system. This is especially important for infants, the elderly, and those with restricted diets, as food alone may not provide enough of these specific nutrients to maintain optimal immune defense.

Immune function may be improved by restoring deficient micronutrients to recommended levels, thereby increasing resistance to infection and supporting faster recovery when infected.
