Review: great find - works great
Review: Great Vitamin D supplement - So I usually have low vitamin D levels. Just by taking a bottle of this, I have normal Vitamin D levels. The ingredients are pure-tasting; I put olive oil under my tongue for about 30 seconds. The texture is like a nice oil, and the taste is like olive oil. Very easy to use. I have not had any side effects from this supplement, aside from increased energy. Quality ingredients from this brand

### ⭐⭐⭐⭐⭐ Great Vitamin D supplement
*by S***S on August 13, 2026*

So I usually have low vitamin D levels. Just by taking a bottle of this, I have normal Vitamin D levels. The ingredients are pure-tasting; I put olive oil under my tongue for about 30 seconds.

### ⭐⭐⭐⭐⭐ Increased Vitamin D Levels - Great Product!
*by J***E on June 17, 2026*

I was consistently using 5 drops per day of this Vitamin D. I had my blood tested and my Vitamin D levels were in the 80's. Then I did an experiment and stopped using it for about 6 months. Retested my Vitamin D and it was in the 30's. Suffice to say, I will resume using this product (5 drops per day) to get my Vitamin D levels back up. On another note, I love the simplicity and price of this product. And also how you can easily adjust the amount of Vitamin D you wish to take. I have given 2 dropperfuls to my son for a couple of days straight to avoid a trip to the hospital for an asthma flare up. It is a really great product and I always have it available.
