Boost Immune Function Vitamin B12 is essential for producing white blood cells, which are pivotal for proper immune system functioning
44 An open-label, uncontrolled trial in 51 patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) found improvements in 34 patients after 3 months of supplementation with hydroxo-B12, 10 000 mcg twice per week as nasal drops
That's why the Office of Dietary Supplements states that people over 50 should gain most of their B12 from dietary supplements or fortified foods
