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.

The order and delivery went very well and I have no issue with that at all. I am taking 8000iu as a Vit D3 protocol and am also taking Vit 2- MK4 in the evenings to help the calcium in my body be directed where it should go, to the bones, teeth and nails rather than soft tissue where it could be dangerous. So far I am feeling stronger since starting my protocol so I am happy with that and for the first time in my life my nails are growing and so much stronger than they've ever been. After 51 years of having nails that were like tracing paper, peeling in layers down half of my nail, truly horrific, it is absolutely no coincidence that now they are healthy after starting my protocol. I intend to continue my protocol and am due a blood test in about one month time. I have every confidence my levels will be in the normal expected range. So... so far so good.
