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!

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.

Easy pull to swallow
Highly recommend for anyone looking for a simple, effective daily vitamin! Energy: Provides a noticeable boost—feel more energized throughout the day. Gentle on the stomach: No upset stomach or digestive issues. Easy to take: Small, easy-to-swallow capsules with virtually no taste. Effective dosage: 1000 IU, exactly what my doctor recommended for daily use. Absorption: Seems well absorbed, I feel the benefits consistently.

Go to D3 for daily use in NE
I just love Thorne... This vitamin d three is great because it's not a super high potency, and the capsule form is much easier for me and my family to take particularly because it is a capsule. Might be a little more expensive than some others. In general, I think that this product is superior to other d3s. Subjective...yes... although we've tried many companies.

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.

It works
What can I say. Worked for me. My D level was low. Took the 5,000 every other day. Now my D level is good
