Very effective, high quality product
August 17, 2012
Vitamin D3 5,000 IU is a very high quality product that really works. It was recommended by a nutritionist that I see regularly. I have been taking it for 2 years. After having had a blood test for my vitamin D level, which turned out to be low, I started taking a less expensive brand of vitamin D3, 5,000 iu, thinking they were all the same. Upon subsequent testing I was dismayed to discovered that after 4 months of taking it, it did absolutely nothing to raise my vitamin D level. It simply didn't work. I began taking DaVinci Vitamin D3 5,000 which brought my level up to where it should be and a bottle lasts for 4 months.
I now realize that there is a huge difference in the quality and effectiveness of supplements on the market and this product I will continue to use.
Pros:It really works.
