    Good product!

    My Vitamin D level was barely normal, in spite of taking a DAK supplement. I started taking this product about a month ago and have noticed improvement in my general health. I believe this product was helpful. I will continue it.

    Thorne D-5000

    I have been taking Thorne D-5000 for over 5 years. My doctor recommended that I take Vitamin D for my bone health. I am 69 and my bone density is very good. I will continue to take Thorne D-5000 for the foreseeable future.

    Bone health

    By taking 5,000 IU each day and 10,000 IU on the weekends, I am able to keep my Vitamin D at a healthy and effective level. Studies have shown that our level should be at least 50 and by taking this product, my Vitamin D level is maintaining this level quite nicely. It's easy to swallow with no aftertaste.

    Thorne Research D-5000 IU

    My doctor recommended Thorne Research and their products have worked well for me. The vitamin D-5000 is a high dose in a small capsule. I will be purchasing this product again.

    Keeps Vit D levels up during winter

    During cloudy winter months, my naturopath doctor tests my vitamin D levels. Since using this, I am in the normal zone and I feel it is easier to get out of bed on rainy days.

    D-5000

    Typical Americans do not get enough sunlight to produce adequate amounts of vitamin D, so taking this as a supplement is necessary.

    Immune booster

    These small capsules are easy to take and help with the lack of sunshine during the winter. I haven't gotten sick yet this year and I beleive it is from the D3. Most people don't get enough D especially when you work indoors.

    Pacific NW residents need Vit D

    Living in the Pacific NW has its challenges. We only really make our own VitD in August. I use the Thornes Vit D 5,000 and take it daily away from coffee for better absorbency. Thorne products have always been of great quality.
