ACS researchers attempt to develop standardized vitamin D testing
WASHINGTON — Vitamin D deficiency or insufficiency may be even more common than previously thought and a risk factor for more than just bone diseases, according to new research published Friday in the American Chemical Society journal Analytical Chemistry.
In an effort to help identify vitamin D deficiency, the authors of the report developed a Standard Reference Material called SRM 972, the first certified reference material for the determination of the metabolized vitamin D in human serum (a component of blood). According to the report, researchers attempting to determine vitamin D deficiency by measuring vitamin D itself doesn’t work because it is rapidly changed into another form in the liver. Current methods detect levels of a vitamin D metabolite called 25(OH)D. However, the test methods don’t always agree and produce different results.
The researchers developed four versions of the standard, with different levels of the vitamin D metabolites 25(OH)D2 and 25(OH)D3 in human serum. They also determined the levels of 3-epi-25(OH)D in the adult human serum samples. They found that this metabolite — previously thought to only exist in the blood of infants — was present in adult serum. “This reference material provides a mechanism to ensure measurement accuracy and comparability and represents a first step toward standardization of 25(OH)D measurements,” the researchers stated.
Between on-half and three-quarters of people in the United States may not have enough vitamin D, and low levels of vitamin D have been linked to the development of several conditions, including rickets (soft and deformed bones), osteoporosis, some cancers, multiple sclerosis and Parkinson’s disease.

P&G and Dr. Oz couple on fan contest featuring Metamucil
CINCINNATI — Procter & Gamble on Monday announced a partnership between its Metamucil brand and the syndicated "The Dr. Oz Show" to help raise awareness around fiber supplementation during Heart Health Month in February.
Fans of the show can enter a sweepstakes at DoctorOz.com/heart2heart for a trip to New York along with two tickets to "The Dr. Oz Show," that includes meeting Dr. Oz. The sweepstakes will be open Jan. 27 through May 7.
During February Heart Health Month, Dr. Oz will be focused on heart health, including offering such tips as taking a psyllium fiber supplement.
In 2011, more than 80,000 Dr. Oz fans had entered for the chance to win a trip to New York culminating in a "heart-to-heart" with the host of that show, Mehmet Oz.
Meda Consumer preps good-better-best iron proposition
ATLANTA — Meda Consumer Healthcare last week featured three revitalized Feosol SKUs, which are set to launch at retail in May, at the ECRM Vitamin, Diet & Sports Nutrition EPPS conference.
The lineup lends itself to a good-better-best merchandising strategy in what has been a commoditized category, and the marketing plan in place to support the launch will mean a significant uptick in promotion of iron supplementation.
The three SKUs include the Feosol Original, an entry-point iron supplement containing ferrous sulfate iron; Feosol Natural Release formulated with carbonyl iron for those with sensitive stomachs; and Feosol Complete, formerly Meda’s Bifera brand, which represents the best in iron supplementation with two forms of iron that helps minimize side effects associated with iron supplementation.
In addition to a traditional marketing campaign, Meda’s pharmaceutical arm also will be raising awareness among physicians around the availability of the three iron supplements.
