Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and cellular metabolism, among others. Mounting research is highlighting the ever-increasing benefits of optimal vitamin D3 status. Vitamin D3 is known to interact with over 200 different genes and thus plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes.

Softgel is very easy to swallow, small in size. I like the fact that they have used extra virgin olive oil. 2,000 IU = 50 µg vitamin D3, the best form of vitamin D. You should meaure your vitamin D level sometimes to see that you are getting enough this very important sun vitamin. I have measured my blood serum 25-Hydroxyvitamin D, 25(OH)D three times and last time my test result was 141 nmol/L = 56.4 ng/ml. My test result was now at optimum level which is 125 - 150 nmol/L = 50 - 60 ng/ml when you are taking enough Vitamin D. I will continue with the same dosage that is 2,000- 5,000 IU daily to keep my vitamin D level right. There is no need to worry about overdosing because the tendency for serum 25(OH)D to rise when the starting level already is higher is very gradual. I hope you find this review helpful.

To make the long story short, I am heavily Vitamin D3 deficient, with my blood levels dropping to 8-10 mg/nl without taking supplements. I should add that when my blood levels drop below 25 mg/nl, physical symptoms manifest (plaque psoriasis, lack of focus, insomnia, etc.). With a 5.000 IU supplement, they should theoretically be above 40 mg/nl, and above 50 mg/nl with a 7.000 IU supplementation. As such, I am usually taking 6.000 - 7.000 IU, so I bought one pack of Doctor's Best 5.000 IU and one pack of 2.000 IU. My last blood test in August showed Vitamin D3 blood levels around 44 mg/nl. I switched from another brand to Doctor's Best in the second half October, taking one 5.000 IU and one 2.000 IU softgel. By mid November, physical symptoms like those mentioned above had already started manifesting (plaque psoriasis). I took an extra blood test and my Vitamin D3 blood levels had already dropped to 24 mg/nl. Given the very short time and the "inertia" that the fat-soluble Vitamin D3 has, one can simply conclude that the 7.000 IU that I have been supposedly taking were not being getting absorbed at all. It was as if I was taking nothing at all. I switched to yet another product and, with a 10.000 IU daily dose, my blood levels have again risen above 30 mg/nl three weeks later. Therefore, I strongly advise you taking something else.
