The dietary supplements discussed in this course are among the most popular in the United States, according to the 2012 National Health Interview Survey (Clarke, Black, Stussman, Barnes, & Nahin, 2015). The combination of glucosamine and chondroitin was the second most popular dietary supplement choice for consumers. Glucosamine salts and chondroitin, individually and in combination, have been investigated extensively for prevention and treatment of osteoarthritis pain and disease progression. Results have been mixed, with the combination of glucosamine sulfate and chondroitin sulfate showing the most positive results. Some studies show equal effectiveness of this combination and NSAID therapy. After completing this course, the learner will be able to identify and monitor potential drug interactions.

Coenzyme Q10 was number four in 2012, a big increase from 2007, when coenzyme Q10 was not in the top 10 supplements list. Cranberry was the seventh most popular supplement in 2012, staying in approximately the same place among the top 10 supplements.

Melatonin moved into the top 10 dietary supplements in 2012. It was ranked at number four behind fish oil, glucosamine/chondroitin, and probiotics. Melatonin is an endogenous hormone that regulates sleep. It can be used by exogenous administration for a number of circadian rhythm disorders, including treatment of blind patients, DSPS, and sleep-wake cycle disturbances. The learner will be able to understand its advantages and potential drug interactions.

Each of these supplements will be discussed individually and the course will provide the criteria for the effectiveness ratings used for the dietary supplements.
