THORNE Vitamin D3 Supplement - Supports Healthy Bones, Teeth, Muscles, Cardiovascular & Immune Function* - Gluten, Dairy & Soy-Free - 1,000 IU - 90 Servings

So far it is effective, I think I will continue with it.

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!

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.

For me this is an ideal D3 supplement

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.

Love this brand and the vitamins are great on my third order pretty soon!
