Review: Liquid D works for me - I've tried a variety of Vitamin D supplements over the years. This vitamin is in the form of a thick liquid that sits under the tongue until dissolved. It doesn't have a flavor. My vitamin D levels in bloodwork are consistently strong with this form of liquid vitamin versus a pill or tablet. I have had my D level checked over the last 30 years. If I change the variety or brand, the levels drop. Something about this Vitamin D works in my body. Perhaps it is the fact that it is liquid that is absorbed under the tongue. This is a great product.
Review: Love this product - I bought this on the recommendation of my chiropractor years ago when I was caring for my elderly parents. After giving it to them for a few months my dad had a check up with bloodwork and the doctor called later asking what I was giving him bc his vitamin D levels were so good, esp. for someone his age. I was sold - I’ve been taking this ever since. I do 2 drops a day.

This is the best vitamin D. I have taken it for years, so, I decided to also take it with K. It is a very convenient way to take your vitamins. I carry it in my makeup bag so I make sure to take it. It can be absorbed into your tongue. Great stuff!!
