I like the one pill as for 5000 u.
Just started using as my doctor wanted me to get more vitamin D3. I will be seeing her in August to see how my levels are doing. If she want me to continue I will be ordering more and on a regular basis.
Love the product. It is small and easy to swallow. Very happy with it.
Arrived quickly. I like that it comes in 5000IU caplets. Will order again.
