We live in Washington State. The sunshine here is rare during the rainy late fall, winter, and spring.
The last two days it has rained with temps in the mid-sixties to mid-seventies. This means staying inside the house for me. If it wasn’t for the oral dose of D3, I probably wouldn’t be receiving that vitamin.
I live in Washington State but on the sunny and hot eastern half of the state. High last week was 110 at Hanford.
Glad it helps you. The D3 seems to do nothing for my wife’s sinus problems. She doesn’t like to go out in the sun so was hoping it would help.
