Vitamin D3 5000 IU by Seeking Health is a pure and potent vitamin D3 supplement in a vegetarian capsule that provides 5000 IU of cholecalciferol. Many people do not get sufficient vitamin D3 in their diet, and the synthetic vitamin D2 that is often added to dairy products is considered an inferior form of this vital nutrient. Vitamin D3 occurs naturally in fatty fish, cod liver oil, egg yolks, and beef liver. Vitamin D3 5000 IU contains cholecalciferol derived from cholesterol in sheep’s wool, making it suitable for vegetarians.*

Vitamin D is essential for the functioning of many important systems in the body, and recent research has suggested that we may need more vitamin D than previously thought for optimal immune function and long-term health. In some climates, people may be able to produce adequate vitamin D3 from sunlight, but in cooler climates with longer winters, vitamin D deficiency may be more common.*

Vitamin D is required for optimal absorption of minerals including calcium, making it an important nutrient for supporting healthy bones and structural health. It may also play a role in supporting immune health and cellular integrity.*

If you are looking for a lower dose of vitamin D3, consider our Optimal Vitamin D Drops.

Great product
This vitamin D is wonderful! The capsule is tiny and easy to swallow. I felt a difference right away. I do not get sick as often when I am on this product. Review by Erin (Posted on 8/28/2017)
It is so hard to find a quality vegetarian D3 in 5,000 IU. I want to say that this REALLY WORKS! I got my vitamin D tested after taking one of these every day for the past 6-7 months. 51!!

PERFECT considering I started at 18.
I really recommend this product, very easy to digest and metabolize.

Thank you for having this product, it is one of my must haves!

Also price is very reasonable!

Great product, Hi Dose
I have prostate cancer and one of the supplements my Oncologist recommended to take was 5000 I.U. Vitamin D3 daily. Being vegetarian I was so pleased to find this product. The capsule is small and easy to take. I have now used this product for over a year and consider it an important part of my treatment and maintenance regime.
Review by Charlie (Posted on 2/28/2013)
Winter must!
As someone who tends to feel very sluggish and down in winter, having a good quality vitamin D3 supplement is a must. Both my daughter and I have been taking this supplement this winter and feel more balanced than we usually do in the middle of winter. And as with all the Seeking Health supplements I have tried so far, I know it is a high quality supplement! Review by Natasha (Posted on 2/13/2013)
Good product
I think this is a very good product. I feel like it helps my mood. My only uncertainty is that I've recently read that vitamin D is better delivered in an oil base (like fish oil), which this product is not delivered. I'm actually going to experiment with a different product next time to see if I notice a difference. I would also ask Dr. Ben about this before purchasing. He may have an answer. I do feel good on this product, though, and wouldn't discourage anyone from taking it. Review by Shawna (Posted on 1/22/2013)
It's working
I've been exposed to many people this year with the flu my husband for one and I never had any symptoms. I take D3 religiously as well as Dr. Ben's vitamin C. Great products. Review by sunshine (Posted on 1/21/2013)
Awesome Product
I've tried the drops and capsules and like them both. My husband prefers the capsules. They are both excellent products and I no longer have the winter blues. Review by Annette (Posted on 2/10/2010)
Great Product
