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 My health care provided likes my results Because I'm an indoor worker, I don't get enough vitamin D. So instead of getting a prescription I went Swanson's route instead. My health care provider likes my numbers now. Thank you.

Rated 5 out of 5 by from Works for Appetite Control! I bought this a few winters ago because of all the hype on vitamin D. My husband and I didn't notice any 'wow' when taking the first bottle. We ran out, and I did not intend to repurchase. A few weeks later we both noticed a significant increase in appetite. We finally figured out it was due to the vitamin D. We bought another bottle, and soon our appetites were under control-no more munchies and satisfied with smaller portions. We tried an expensive kind, one in olive oil, and never noticed an improvement over the Swanson's brand, so we are back to stay.

Rated 1 out of 5 by from Anything in There? I take one of these daily and its supposed to be 2 1/2 times the daily allowance but my last lab test showed a Vit D deficiency! So I question whether it has the claimed amount of Vit D (or any at all).

Rated 5 out of 5 by from Use as extra boost to 5000 mg Vit D3 I purchase this to use if I want to use just a bit more than my 5000mg gel cap. It is a very small capsule which I like. Happy with this product!

Rated 5 out of 5 by from This is a great product This brought my Vitamin D level back up to a normal rate. I will continue to take it all the time. I think Swanson is the best place to get vitamins, their great prices keep me coming back.

Rated 5 out of 5 by from Swanson's High Potency Vitamin D-3 If you're looking for a high dose source of Vitamin D-3, then all I can say is here it is. Safe and effective. I work graveyard, indoors for 10-12 hours, and sleep much of the day away, so sunlight is rare for me. This helps, especially since I'm getting into my 50's. If this is too high for you, then go with the 400 I.U. instead, also available right here at Swanson.

Rated 5 out of 5 by from I trust Swanson. I trust Swanson to give me a great product at a great price. I am confident with their D3.

Rated 5 out of 5 by from Great Product! I have been taking this for quite a while. When I started ,my blood work showed that I was deficient in vitamin D. My levels were single digit. After taking 4 a day for a while, the next time I had blood work done it showed that my D was too high. So I cut back to 2 a day and my D level stays great. I know that it worked for me. Suggest you have your blood work check your vitamin D level and dose accordingly. This is a great product if used properly.

Rated 5 out of 5 by from So many people deficient in Vitamin D! This is the best D supplement I've come across! Fantastic price as well!

Rated 5 out of 5 by from Special Find I especially like to take vitamins in the dry formula since the gels do not agree with me. It is the only dry vitamin D I have found and I am very pleased with all of its qualities and also the price. Since Vitamin D is so essential I believe I have discovered a "special find" I have been using it for years.

Rated 5 out of 5 by from D3 I like the 1000 IU for this product . I don't like having to take multiple pills just to get the right dose. This is very convenient to use.

Rated 5 out of 5 by from I take it once a day with my calcium, do not know how it works, but I am feeling great.

Rated 3 out of 5 by from wrong form for me I didn't look closely when buying this. I prefer the gel tab form of D at a higher concentration.

Rated 5 out of 5 by from maintain daily Vitamin D !! I love this 1,000 units size -- that way we can take them 4 different times daily to keep levels in the body up more often.
