Pacific NW residents need Vit D

by Chateau -

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.

Immune booster

by PCM -

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.

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

Keeps Vit D levels up during winter

by Julie -

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.

I will buy this product again

by Nana Linda -

For the past three years, my annual complete physical blood-work showed Vitamin D level decline. Three medical doctors—one female, said I needed Vit D3 supplement. After researching at length I found this one with all the ""Healthy"" or correct ingredients. After taking Thorne D-5,000 daily for four months, and then switched to Thorne D-1,000 thereafter, my tests are in normal range again. Must add, the doctors suggested taking VitD along with a good ratio Calcium/Magnesium/Zinc supplement —""Metabolic Maintenance Cal/Mag 1:1"" order from Professional Supplement Center. I sleep better now and overall health is Good for my age now!

Bone health

by Camille -

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.
