No, the vitamin D does come from lanolin oils which is from lamb's wool (aka, sheep).

Has this product been tested by any 3rd party labs for contaminants? I don't see it on labdoor or consumerlabs.com

In case it’s helpful, here is a bit of information I can offer. My naturopath cited several studies/research showing that Thorne products contained exactly what the product label stated. Many other brands that were included in the study contained far less of the nutrients listed. I wish I’d written down the research and testing sources. As I recall they were university-supported nutrition research studies. He has been very clear about his faith in Thorne and Vital Nutrients brands, stating one can even take lower dosages to save cost, because the product will contain exactly what is stated on the bottle. In other words, a product that is 200mg within a Thorne product may be comparable to another brand that claims to contain 300 or 500mg. He also feels strongly that Thorne products offer higher bioavailability. I’m not a scientist - but in case it helps, I wanted to offer his opinion. He’s a naturopath with decades of experience and patients remain with him for life. He hasn’t had room for new patients for ten years. He’s just that good! So, I trust his evidence and opinion. But again- I’m not a scientist :-)

Highly recommend this to anyone looking to support their immune system and maintain healthy vitamin D levels—especially if you don’t get much sun!

Good brand

For the most part we don't have issues. Sometimes there is nothing in the capsule which is super annoying. Most of our supplements are Thorne.

The most reliable vitamin brand we use as a family!

We've tried so many brands, honestly, for different supplements. I've found that simply going to the grocery store and grabbing the first one you see is not the answer. Absorbancy is so key! We now use Thorne supplements for four different vitamins, and are very pleased with the effectiveness, and the consistency in packaging and capsule quality. You get what you pay for when it comes to supplements, and these are such a great value.
