Bests & Worsts Reviews from Amazon

My vitamin D levels were very low (12 ng/ml) Healthy is 30 ng to 100 ng. I tried many supplements for years. I'm a vegetarian so some limitations. Vitamin D has shown to help in lessening the viral load for Covid and I am immunocompromised so I was working hard to find a D supplement that worked. I started this March 2021 at 1ml per day. Three months later my D was 74 ng/ml. We were hoping for anything over 30. My doctor didn't think I could get a number this high. The stopper for the first 4 bottles did have an issue with not dispensing a full dose so I had to dispense it twice but bottle 5 is dispensing the full 1ml. I still take it every day. My friend also takes it but less religiously and her D is now 42ng/ml up from 25 ng. My sister takes half a dose as she was already in the safe range. It does have an unpleasant taste but I immediately drink water and eat something and it is worth the minor unpleasantness. I will take this for the rest of my life unless it stops working.
