The festive season is a time of year that should be filled with parties, delicious food and quality time with your loved ones – which are all things you can’t enjoy to the same degree if you’re fighting through a cough, cold, or flu.

Luckily, Amazon has just launched a well-timed sale that will help you boost your immunity by making sure you don’t have any vitamin deficiencies that may make you more susceptible to illness.

The retailer has slashed up to 55 percent off vitamins and supplements such as vitamin D, collagen, multivitamins, vitamin C, and a whole lot more in order to help you make sure you’re in tip-top shape in time for your Christmas and New Year celebrations.
