This Vitamin D3 works the best
My vitamin D level used to be very low and the doctor had to prescribed me the Vitamin D pill
which was very high dosage and I was required to take one pill per week. Every time I took the pill, it seemed that I got a diarrhea. Make a long story short, I found this one, the second year my blood report, my vitamin D level came to normal level. Highly recommend this products. This time my order is for my mother.
