Review: Excelent - that vitamin D3 helped me a lot I will buy it again
Review: Easy and Affordable - This is a great way to get my vitamin D3 during the winter months. I take it every Monday instead of taking a D3 everyday. No side effects and I feel great. I think it also helps with being in a better mood but that is hard to prove that it is the D3. I would recommend this D3.

### ⭐⭐⭐⭐⭐ Works great!
*by M***S on December 13, 2021*

I was encouraged to really up my D levels after having calcaneal osteotomy with a graft that has been slow to heal/fill in. After switching to the once a week 50k Nivagen (had been on the 10k @ 5x a week Designs for Health supplement) my levels are now in the 80s range. The other supplement did take me from 31 for the last 5 years to the 50s range after 3 months so both are effective. I prefer the once a week option in this tiny pill as it's easy to take, is more affordable and lessens the number of pills I take in a day. As a side benefit, it's helped me get off the buproprion I'd been on for 5 years! Yay!
