Vitamin D-3 from Source Naturals is a bioactive form of vitamin D specifically for bone and immune health support. Sunlight is the source of life on Earth, but we may not be aware of all the ways it may benefit us. Our bodies manufacture vitamin D3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D3 maintains healthy calcium and phosphorous levels in the body for strong bones, and new research is being done to investigate its potential role in immune health support. Vitamin D3 (cholecalciferol) is the form the body naturally manufactures, and it is the form most efficient for the body's needs.

Rated 5 out of 5 by from Vitamin D-3 Great product at extremely reasonable price!
Date published: 2013-05-31
Rated 5 out of 5 by from Easy to Take This supplement is easy to take and a very good value for 2,000 IU. What I really like about this product is that a small amount of calcium is added to each tablet making it more rounded, and in my opinion, helps the absorption of the D. I prefer the 2,000 unit size since if I want to take more I can or I can just take one pill to obtain my desired dosage.

Q: Why are some vitamin D products measured in IU while others are in mcg?

Due to changes in FDA labeling guidelines, vitamin D amounts must now be listed in micrograms (mcg) on supplement facts and nutrition labels instead of international units (IU). Although these new guidelines were issued in 2016, updates weren't required until June 2020.

At Swanson, we began updating our labels in early 2017. You will see a mixture of both IU and mcg as our national brand partners complete this process.

Q: Did my vitamin D supplement change?

A: You may have noticed a change in the daily value percentage on your favorite vitamin D product, but that doesn't mean your product changed. The FDA increased the recommended daily intake (RDA) of vitamin D, which means the same product with the same ingredient amounts fulfills a lower percentage of the RDA than it prior to the change.

Q: How much vitamin D do I need each day?

In 2016, the Food and Nutrition Board increased the Recommended Dietary Allowance (RDA) of vitamin D for most adults from 10 mcg (400 IU) to 15 mcg (600 IU) per day, and 20 mcg (800 IU) for ages 70+.

Some doctors and nutritionists recommend higher daily vitamin D intakes, especially for those at risk for having low levels. The Vitamin D Council, an organization dedicated to raising awareness about vitamin D, recommends average adults supplement with 125 mcg (5,000 IU) of vitamin D daily. Talk with your doctor about your individual needs.
