My wife knew!

She’s been telling me for months to take some! She even got some reinforcement from a CDC article that stated that Vit D deficiency is a key reason that the flu season is in the winter, when people get less exposure to the sun, and thus, their vitamin D levels drop. I can post the link if you’d like.
We both take 4000 IU’s per day now.
