Winter immunity essentials in Bangladesh from Australian Goods Bangladesh

Trusted Australian and New Zealand supplements for Bangladesh’s winter season.

Bangladesh winters bring drier air, shorter daylight, and a rise in seasonal colds. A steady routine of evidence-based nutrients, quality sleep, hydration, and light activity can help your immune system respond faster. Below are the five most relied-on supplement categories, with usage cues tailored for local routines.


1) Vitamin C – The First Line of Winter Defense

  • Best picks: Swisse Ultiboost High Strength C / Healthy Care Vitamin C 500mg Chewable
  • How to take: Once daily with water/juice. Split dose if your stomach is sensitive.
  • Common mistake: Skipping on weekends — consistency matters for winter resilience.
