Emergen-C is 25% off on Amazon, and the flash sale couldn’t come at a better time.

Flu cases are ticking up this year, and the illness is spreading fast and hitting hard. Preliminary NYC hospital data indicate more people visited the ER for flu symptoms the week before Christmas than they did during any other week in the last decade. The strain even earned itself the title of the ‘Super Flu.’

As someone who just recovered from a two-week-long bout with it, I can confirm the so-called Super Flu was just as gnarly as people were saying it was. Besides sitting in bed, sleeping it off and sniffling up a storm, the one thing that helped me feel a little less like a zombie was my daily dose of Vitamin C.

A single serving of Emergen-C powder delivers 1,000 mg of vitamin C‚ which accounts for about the same amount you’d get from 10 oranges. It’s also packed with B vitamins, antioxidants like zinc and electrolytes, which can help with hydration when you’re under the weather. The powder mixes easily and, in my opinion, tastes like a refreshing raspberry lemonade, so taking it is really no hassle.

It’s no wonder that reviewers rave that it’s a cold-season “health essential.” While it didn’t ease all my flu symptoms, I felt that my daily dose of Emergen-C gave me the energy boost I needed to take care of myself and my sick toddler — and that made it feel like the best $12 I’d ever spent.
