    Pure, High-Potency Vitamin D

    Vitamin D's reputation as a super nutrient is now well-established, but many people still aren't getting enough. Boost your overall health with a boost from D-5000 by Thorne Research.

    D-5000 contains a potent 5000 IU of pure vitamin D3 per capsule for healthy bones, immune function, and cell growth.

    Although our bodies can produce vitamin D by absorbing ultraviolet radiation from the sun through the skin, in our indoor lifestyles, many people aren't getting sufficient amounts through the traditional method. With office jobs, increased screen time, temperature extremes, and indoor luxuries, people are spending less and less time outside.

    The elderly and many individuals in colder climates are at increased risk for vitamin D deficiency - and it can take large doses to restore healthy levels.

    To ensure the healthiest way to replenish vitamin D stores, Thorne Research uses no hidden ingredients or fillers like lactose, BHT, BHA, sodium benxoate, or sorbic acid. And D-5000 is made without flowing agents that can inhibit bioavailability.

    To restore or maintain your vitamin D levels, choose a supplement from a company that's dedicated to quality. Choose D-5000 by Thorne Research.

    Professional-grade products adhere to the strictest standards for purity and potency, and use the highest-grade ingredients available.

    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.

    I appreciate the quality

    I trust the quality of Thorne Research supplement products and am pleased to be able to buy them from Natural Healthy Concepts. I used to have to get them from my Holistic Md.

    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.

    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.
