How to Boost Immunity Before Flu Season

As the days grow shorter, our bodies produce less vitamin D. Vitamin D3 plays a key role in activating immune cells, so a daily supplement of 1000 to 2000 IU is a common recommendation during winter. Ask your pharmacist about the right dose for you.

Zinc supports the development of white blood cells and can shorten the duration of a common cold when taken early. Pair it with vitamin C for a well-rounded immune routine.

Nutrition matters just as much. Build your plate around colorful vegetables, citrus fruits, garlic, yogurt with live cultures and oily fish. Stay hydrated, sleep seven to eight hours and keep moving every day.

Finally, do not forget the basics: wash your hands frequently and consider your annual flu vaccine.
