Do you get enough of the powerhouse Sunshine Vitamin? The body manufactures some vitamin D on its own when it is exposed to sunlight—hence the nickname—but for people living in the northern latitudes where wintertime sun exposure is limited, the body's natural vitamin D production may not be enough. Swanson High Potency Vitamin D-3 capsules tackle this problem by supplying an impressive 1,000 IU of vitamin D-3, the most biologically active type of vitamin D. Vitamin D-3 is an essential bone supporting nutrient that works to absorb calcium efficiently in the body and also supports a healthy immune system.* 


Q: Why are these considered dry?
A: They are considered dry because the vitamin D-3 is not suspended in a liquid oil; rather, it is in a dry powder inside the capsule.

Q: Is the vitamin D-3 in this supplement sourced from fish or lanolin?
A: It is from lanolin.

Rated 5 out of 5 by from Vitamin D high IUs This brand is the only one I could find with 1,000 IU. Taking two a day under doctor's advise. Considering the natural amount I thought I was getting, I didn't think I needed this. Tests proved differently. Excellent price. You only have to take one instead of several pills in other brands.

Rated 5 out of 5 by from Great Value This is a good size dose. Less pills to take with the new higher Vitamin D recommendations

Rated 5 out of 5 by from HP Vitamin D-3 very effective Noticing that my Vitamin D levels were too low, I began a regimen of 1 capsule per day and within 60 days my levels were far above targets. It performed exceptionally well.
Date published: 2009-08-28
Rated 5 out of 5 by from Right size for swallowing I've found that I need to take 3 of these a day. I love that it is in a 1000 mg per tablet and that the pills are small enough to swallow easily.
Date published: 2009-08-20
Rated 4 out of 5 by from "D"vine! Correcting my vitamin D deficiency has really made a difference in how I feel. This higher dose supplement made it much easier to take the recommended amount I needed to bring my level up. The quality is good and the price can't be beat!
Date published: 2009-08-18
Rated 5 out of 5 by from great value Vitamin D3 is a great value and I recommend it to anyone. Easy to take and fits my needs. This is a great health protection for me. I was quite pleased to see that Swanson is keeping up with all the latest research to keep their customer's happy and healthy.

Rated 5 out of 5 by from Vit. D3-the feelgood vitamin I take this vitamin because I was told I was low in vitamin D---probably because of using Sunscreens...Like a Catch-22...But while using this vitamin---2 a day---I have felt so much better physically. I know that I cannot say for sure, but even my skin looks clearer. For some reason I even feel stronger. I guess between the calcium and Vitamin D3 there has to be a win-win situation.
Date published: 2009-08-06
Rated 5 out of 5 by from I'm Not Deficient! As a pale person, I wear sunscreen to go outside without burning. I take 2 capsules most mornings. My blood test just indicated excellent Vitamin D levels.

Rated 5 out of 5 by from Great Product I am so pleased with the Swanson vitamin D3 capsules. The D3 formula is exactly what type of vitamin our body uses, allowign for easy absorption. Plus the capsule is easy to swallow. I am indoors quite often so I get the benefits of the sun on indoor and rainy days.

Rated 5 out of 5 by from Excellent Vit D product My doctor told me to start taking VIT D. I take 6 if your VIT D 3 each day & my Vit D levels continue to be within range at every doctor's visit. It's working.

Rated 5 out of 5 by from Sun's little helper in a bottle Living in the Northwest, I'd become aware that a great majority of northern latitude residents are deficient in D-3. I certainly fell into this category. It's a slow build, but my deficiency is shifting...and I look forward to going into next winter with a healthy balance.

Rated 5 out of 5 by from D-3 This is a very good product. I take it with my calcium everyday.

Rated 5 out of 5 by from This Workks! Our daughter tested noticeably low for vitamin D levels. We used this product for two to three months and her level then tested excellent. Who says you have to buy expensive vitamins to get results? Thanks, Swanson!
Date published: 2009-01-01
Rated 5 out of 5 by from nice size, convenient product the 1000 IU size is very convenient and allows simple seasonal adjustment if desired. The dry d3 for should be pretty stable. The price is excellent, this product works for me.

Rated 5 out of 5 by from Super sunshine without the burn. I believe this supplement to be a help in the days of winter.
Date published: 2008-12-05
Rated 5 out of 5 by from a must have for office workers It is one of my must-haves supplements. Nearly all of us have deficiency of sunlight and consequently deficiency of vitamin D. Even when we go in the open air a lot of us put sunscreens (I dont, as I live in a very mild climate). This supplement is necessary for office workers, I take 2 tablets per day during winter, 1tablet for nearly the rest of year excluding 2-3 brightest summer months of the year when I try to spend as much time as possible outside. Swansonvitamins provide this important vitamin at a very affordable price, I have never seen it any cheaper, and the quality is excellent.
Date published: 2008-11-07
Rated 4 out of 5 by from Vitamin D-3 A good product that I mainly take in the winter months and find that it works very well to maintain proper levels of Vitamin D when adequate sunlight is not available. Some of the reviews are concerned about excess fillers and even sucrose being added as a filler. The formulation for this product could be changed to eliminate some of these items and keep the product as true to Vitamin D as possible.
Date published: 2008-11-03
Rated 5 out of 5 by from Doctor's Orders My wife is required to take Vitamin D supplements and this is the best value I have found.
Date published: 2008-05-26

Date published: 2008-04-09
Rated 5 out of 5 by from high dosage-great value I live in Stockholm, Sweden where during the 5 winter months there is not a great deal of sunlight available. I use Swanson's 1000mg D3 as a valuable supplement to offset this deficiency of daylight, not to mention the important fact that they also provide a high quality low price product.
