Rated 5 out of 5 by from Tiny and Mighty There are so many health benefits associated with Vitamin D. It's very important to get adequate amounts. Easy to swallow and great value.

Rated 5 out of 5 by from Doctor's Best Vitamin D3 I wish that Swanson offered a small, 1000 IU D3 gel like this, however, this is a very good brand, and I would recommend it if you are Vitamin D deficient. Though I probably need more, one gel, twice a day, several hours and meals apart is all my tummy can handle of any brand of D.

Rated 5 out of 5 by from Great Product This product has worked well to bring my husband's vitamin D3 level in a good range. He took a higher dose with the Swanson label and it didn't help.

Rated 5 out of 5 by from Affordable and well absorbed I have researched the best vitamin D since mine runs low in the winter. As a Registered Dietitian I use and recommend this product.

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.
