I too, have had a vitamin D deficiency for years and my doctor kept asking me to take a supplement, but I always foud the pills hard to swallow. Last year I found these ddrops hes at my local Whole Foods - 2 drops on my wrist, licked off each morning, and I have 2000 IUs in less than a second - easy, tasteless, but very helpful! For the first time in 5 years my Vit D levels were normal at my appointment last month! It's about $30 for a 3 month supply, and worth it!
