Product Overview


  • Dietary Supplement

Vitamin D in liquid form for easy dosing

  • Liquid form allows for easy dosing for children and adults
  • In medium chain triglyceride oil – no soy or sesame oil
  • Preserved with mixed tocopherols (natural vitamin E)
  • 500 IU of vitamin D per drop

It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age. Vitamin D helps protect a number of important functions in the body. The current recommended daily vitamin D intake of 200-600 IU for adults is based on the minimum allowance to protect against bone disease. However, an upward revision of the FDA's guideline is now under consideration in light of new research, especially pertaining to immune function. Although direct sunlight exposure is a good source of vitamin D, many people do not get enough sun due to season change, latitude, or lifestyle. Therefore, vitamin D supplementation can be of great benefit in these cases.

The Vitamin D Council (VDC) is a non-profit organization of medical professionals, vitamin D researchers, and concerned citizens whose goal is to educate professionals and the public on vitamin D deficiency and its associated health risks. The VDC recommends an average of 5,000 IU/day vitamin D for adults. Better yet, they suggest testing 25-hydroxyvitamin D levels and dosing accordingly. Ideal blood levels should fall between 50-80 ng/mL.

Infants should not receive more than 400 IU/day, which is the daily dose of vitamin D supplement that the American Academy of Pediatrics recommends for breast-fed and partially breast-fed infants.

Thorne Research's Vitamin D Liquid is in a base of medium chain triglyceride oil, preserved with mixed tocopherols.

Suggested Use

Take 2 drops one to three times daily or as recommended by your health-care practitioner. Invert bottle to dispense individual drops. May be added to food or mixed in beverages.

Very Very Effective!

Posted by iHerb Customer on May 22 2017 | Verified Purchase

The only vitamin D brand i will ever buy again! For years my daughter had very low vitamin D levels. Of course the doctors never told us the importance of it. My mistake for trusting them. For years we tried to get her levels up but nothing was working. A combo of this and the thorne vitamin D with K/2 did the trick. Levels went from 18 to 67 in a couple of months!!!

Thanks for your feedback!

Liquid form!

Great that vitamin D comes in liquid form, makes it so much easier for smaller children to take.

Thanks for your feedback!

Made my skin break out badly.

Posted by iHerb Customer on April 30 2016 | Verified Purchase

After a few weeks of taking the supplement I started getting terrible acne on my forehead and brow line. I've never had cystic acne before. After doing some research, I discovered that I can't tolerate vitamin d supplements. The acne cleared up after I stopped taking it. I bought a Sperti UV lamp because I want to get vitamin d naturally. It won't raise your vitamin d level too much, but it works. I use the lamp everyday and my d level stays around 50 mg.
