December arrives with cold, dark winter days, drawing us indoors to heated spaces. Dry air and mucous membranes create a perfect environment for cold viruses, which spread rapidly through coughing and sneezing droplets.
Acute and chronic infections often deplete vitamin C levels. Think of it like a bank account: deposits (daily intake) build reserves, while withdrawals (metabolism, immune demands) reduce them. As a water-soluble vitamin, vitamin C isn't stored extensively, requiring regular replenishment. Infections spike consumption, rapidly lowering blood levels.
Unbalanced diets often provide less than the recommended 75 mg daily for adults over 14. Food loses vitamin C through poor storage, heat-sensitive preparation, and limited gut absorption via specialized transporters in the small intestine—meaning only a fraction reaches the bloodstream.
During the onset of a cold or flu, immune cells rapidly consume vitamin C to combat pathogens. Without replenishment, the immune response may weaken.
Boost intake with vitamin C-rich fruits and vegetables. Severe deficiency signs include bleeding gums and subcutaneous hemorrhages—consider supplements in such cases.
