Excellent Vitamins D

I’ve been using Thorne Vitamin D for a few months now, and I can truly feel the difference in my energy, mood, and overall health. The quality is top-notch, and I trust Thorne for their clean, science-backed ingredients. It’s easy to take, gentle on the stomach, and I love that it’s tested for purity. 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! Read more

Never want to be without this

I am convinced this is a great product. I think Thorne is a great company and the vitamin D3 supplement has definitely strengthened my bones. I am 84 years old and I tripped over my husband's wheelchair and landed on my wrist. I am convinced that had I not been taking this high quality supplement I probably would have broken my wrist. I am so grateful that didn't happen. Read more

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. Read more

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. Read more
