  • Supports bone health, immune wellness, cardiovascular wellness and more

  • Promotes calcium absorption in the body

  • Our most potent dose with 5,000 IU per serving

Swanson Premium Vitamin D-3 5,000 IU is our highest potency vitamin D supplement available. Did you know that 75–90% of people in the U.S. are deficient in vitamin D? Very few foods in nature contain vitamin D, and if you live in northern latitudes, it’s even tougher to get enough of this sun-loving, super vitamin. Vitamin D helps your body absorb calcium, making it a critical part of healthy bones, but it also functions in immune health, cell growth, and inflammation moderation. New research has also revealed that vitamin D-3 may be twice as effective as vitamin D-2 at raising nutrient levels in the body, making this high-potency softgel one to make sure you stock up on!

Rated 5 out of 5 by from A truly fantastic product! My vitamin D-3 levels were below normal in lab tests until I began taking Swanson's Highest Potency Vitamin D-3. I have been using this product daily for the last two years and my vitamin D-3 levels are perfect now!

Rated 5 out of 5 by from Vitamin D3 My doctor wants me to take 20,000 I.U's a day and most vitamins are either huge or i have to take a handful to reach 20,000, Swansons Highest potency D3 is the same size as 100 i.u, so just having to take 4 a day is much better than 20 of the 100 i,u's I would recommend these to anyone,who has to take Vitamin D3 Thank you

Rated 5 out of 5 by from Blood tests show high vitamin D levels I've used this particular vitamin D3 for several years. I take it as directed on the bottle - one capsule once per day. Blood tests have shown excellent levels of vitamin D. The doctor says whatever I'm taking, keep it up.

Rated 5 out of 5 by from Take Daily I take this 5000 iu daily and have for several years. I just went into my VA doctor for an annual check up. They check my blood and he ALWAYS has said that my vitamin D was excellent. This time he said that it is perfect and asked me what dose I take. I told him and he wrote it down. It is very hard to find many supplements locally that Swanson has. Several other supplements that I take I am not able to find locally, that I purchase here. You just can't go wrong buying from Swanson. Just my opinion. I also take Acetyl L-Carnitine (1000mg daily) and Pregnenolone (50mg) daily for my mind. Also a multivitamin, and fish oil supplement that I purchase here at Swanson Vitamins. I believe that supplementation for our diet is SO very important!! It really helps my body and I CAN tell the difference.

Rated 5 out of 5 by from Just what was ordered My blood tests showed my vitamin D level was way under normal. This is the potency I take daily.

Rated 5 out of 5 by from High potency in a small Sgel What I love about this product is the size and the potency. If you take more than 4 other vitamins a day you dont want them to be big so the smaller the better and if it is high potency even better I wish all pills were this small. I gave it four stars for effectiveness because its hard to tell the effectiveness but I am pretty sure its working.

Rated 5 out of 5 by from Doctor's order I am glad I have been able to find vitamin D in 5000 IU since a while back, doctor order for me in a prescription form. I was not able to find at other vitamin stores in the specific 5000 IU, thank you Swanson for making it available.

Rated 5 out of 5 by from Affordable and Effective This product is very affordable and easy to take - the gel caps are quite small. My recent blood work showed a healthy level (and a higher level than previous Vitamin D tests showed) for vitamin D which I believe is in part due to taking this product.
Date published: 2017-01-01
Rated 5 out of 5 by from A great choice for vitamin D My doctor suggested I take a Vitamin D supplement. I chose Swanson's 5000 IU, and I am very happy with this choice. The price is very reasonable and the ingredients are of superb quality.

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.

For more information about these changes, see Nutrition Label Updates: Important Changes to Sugar, Fiber, Vitamin D & More.
