Recently moved to an area of the country where the sun is none existent most of the day.....I ordered these because I felt off I’ve been taking them for 3-4 weeks and I can feel a huge difference with my hormones

When I was younger I was on prescription strength Vitamin D and Calcium due to a bone disease. As I got older I forgot. I ordered these to make sure I am getting the required amounts I need. The pills are small and easy to swallow. Will buy again.

I take vitamin D3 during the winter as I live in WI and it helps improve my mood quite a bit! Vitamin D3 also helps with immunity...I'd assume then probably why I rarely get sick. I'm sure it helps with that factor a lot too. I've been taking vitamin D3 for about 5 years now. I'm really impressed with's signature series! I love that the pills are small and easy to take!

large amounts of vitamin D3 (cholecalciferol) are made in your skin when exposed to sun. Well, your girl lives in the cold and dark mid west. Very happy with this product! Helps me get the vitamin D I miss in our glorious winters!
