LOUISVILLE, Ky. — It's the season of sharing... gifts, memories, food but sometimes we receive gifts we don't want.

We're not talking about that ugly Christmas sweater - we're talking about germs.

Who has time to be sick during the Holidays?

Immune boosters they are hot sellers especially when it's cold.


Can 'immune boosters' help keep you from getting sick?

Our verify team took a look at that claim.

Dr. Joshi lists the key ingredients for increasing immunity:

  • Vitamin C
  • Vitamin D
  • Zinc
  • Echinacea

"There has been evidence-based research that has proven that these four can decrease the incidents of common colds also the severity and duration of common colds," Dr. Joshi said.

Yes, taking supplements can boost your immunity.

But are you getting the right dose to give you that boost?

Sometimes these supplements are already in your daily vitamin but Dr. Joshi said it is safe to take an extra tablet of both vitamin C and D. Don't forget to double up on Zinc too.

If echinacea is more your cup of tea, it may not be as potent as you thought.

"The studies have shown that you have to take an average dose of 2000 to 2400 milligrams per day for a good three to four months through the season," Dr. Joshi explains.

You may have to drink two cups of echinacea tea each day - just check the label for the amount.


So yes, we verified, when taken properly both vitamins and herbs can boost your immunity - and keep you happy and healthy during the holidays.
