Great product. I don't like to take pills and this works perfectly for me.
Excellent product. I have trouble taking pills and this liquid vitamin D is perfect!
Douglas Labs’ products come highly recommended by a physician friend of mine with a PhD in pharmacology. The liquid vitamin D is preferable to tablets for effectiveness.
I have used this product for personal use for about 3 years. It has significantly improved my blood lab work when Vitamin D levels are checked. I recommend this highly to everyone.
