SourceOnes CoQsource® Higher Bioavailability

CHICAGO—SourceOne Global Partners announced the peer-reviewed journal, Alternative Therapies in Health and Medicine, published the results of a double blind study comparing the bioavailability of patented CoQsource® to three other bio-enhanced coenzyme Q10 (CoQ10) formulations (March/April 2009; 15(2)). The study is entitled, “Relative Bioavailability Comparison of Different Coenzyme Q10 Formulations with a Novel Delivery System”.

According to Dr. Zheng-Xian Liu, lead author of the study and author of more than 60 other peer-reviewed published studies, the scientific and medical community has emphasized the importance in supplementing with CoQ10 and improving the uptake and bioavailability in CoQ10 formulations, especially with the dramatic increase in the number of people taking stain drugs.

In this study, the relative bioavailability of a single oral dose of 120 mg of CoQ10 was assessed using the area under curve (AUC (0-10h)) in which the value for CoQsource reached 30.62 µg/ml/10h; a 622-percent higher bioavailability than the oil-based formula and a 499-percent higher bioavailability than the solubilizate.

“These are the most compelling clinically proven absorption results of any CoQ10 formulation that have been published to date,” said Dr. Liu.

CoQsourc is a patented, lipid-based formulation that naturally self-assembles on contact with an aqueous phase into an association colloid delivery system known as VESIsorb®.

Developed by Vesifact, Baar, Switzerland, VESIsorb is protected worldwide by multiple U.S. and international granted and pending patents. Marc Weder, co-founder and CEO of Vesifact, commented: “These results highlight the many advantages that this delivery system represents. We have been able to broaden the applications for certain bio-active ingredients like CoQ10 into functional foods, drink mixes, beverages and cosmetic products. We have succeeded in this area by addressing issues such as water solubility, oxidative stability, shelf life and uniformity of dispersion in the delivery medium.”

Weder added that Vesifact’s newest research has focused on utilizing VESIsorb with omega-3 concentrated EPA/DHA (OmegaChoice™) alone and in combination with CoQsource; and utilizing VESIsorb with citrus flavonoids (PMF-source™) alone and in combination with palm tocotrienols (TocoSource®).

“It is clear that CoQsource is the most exceptional and exciting CoQ10 formulation available with regard to its pharmacokinetic profile,” said Jesse Lopez, CEO and Founder of SourceOne. “This study showed higher relative bioavailability not compared to CoQ10 powder, but compared to patented soft gel enhanced absorption delivery systems. The results speak for themselves.”

This technology allows SourceOne to offer bio-enhanced ingredients and proprietary formulas containing CoQ10 in either the ubiquinone or ubiquinol (QH) forms. Lopez added, “Perhaps even more compelling is our ability to deliver proprietary Omega-3 and CoQ10 combinations along with utilizing the VESIsorb delivery system to significantly improve the absorption of other natural lipophilic bio-actives such as vitamin D3, resveratrol, citrus polymethoxylated flavones (PMF), palm tocotrienols, and gamma-tocopherols.”

CoQsource is available worldwide exclusively from SourceOne in various potencies up to 200 mg. SourceOne can offer a 100-percent water-soluble form of CoQ10 and deliver the formulation in solid dosage forms, drink mixes, stick packs, food products, beverages

Choose Your Meats Wisely

VICTORIA, Australia—Results from a study published online in the American Journal of Epidemiology suggest different meats may differently affect age-related macular degeneration (AMD) risk and may be a target for lifestyle modification (2009) (DOI:10.1093/aje/kwn393). The authors conducted a cohort study of 6,734 persons aged 58 to 69 years from 1990 to1994. At follow-up (2003 to 2006), bilateral digital macular photographs were taken and evaluated for AMD (1,680 cases of early AMD, 77 cases of late AMD). Higher red meat intake was positively associated with early AMD; the odds ratio for consumption of red meat 10 times/week versus less than five times/week was 1.47. Similar trends toward increasing prevalence of early AMD were seen with higher intakes of fresh and processed red meat. Conversely, consumption of chicken 3.5 times/week versus less than 1.5 times/week was inversely associated with late AMD.

Hispanic Consumer Spending on the Rise

NEW YORK—With buying power of nearly $1 trillion, the 46 million Hispanics (Latinos) living in the United States are wielding an increasingly powerful influence on the American consumer economy, according to a new report from Packaged Facts. The market research firm noted expenditures by Hispanic consumer units grew at double the rate of expenditures by non-Hispanic consumers between 1995 and 2007, and will show a cumulative growth rate of 31 percent by 2013. Gen X and Gen Y Latinos exert particular influence, controlling 60 percent of all Hispanic buying power, and may heavily impact decisions in industries including entertainment, apparel and children’s goods.

Further details on the report, The Hispanic (Latino) Market in the U.S.: A Generational View, 7th Edition, is available online.

Organic Farming Delivers Healthier Food

PULLMAN, Wash.—A panel of scientists at the annual meeting of the American Association for the Advancement of Science (AAAS) affirmed the fact that organic farming delivers healthier and more nutritious foods as well as richer soil, but also said organic farmers need better tools to maximize their efforts.

During the symposium titled “Living Soil, Food Quality, and the Future of Food” the panel presented six encouraging conclusions on the impacts of organic farming on soil quality and the nutritional content of food.

“The work we reviewed over the last decade points directly to two major scientific challenges,” said Dr. Preston Andrews of Washington State University. “First, we need to understand more fully how soil biological communities’ process nutrients and communicate to plant roots in order to promote improved quality in organically grown crops. Second, we need better tools to help organic farmers fine-tune their production systems in order to maximize the soil and nutritional quality benefits of organic farming.”

Upping Phytonutrient Levels in Black Raspberries

WOOSTER, Ohio—The prospective health benefits of black raspberries and other antioxidant-rich produce has led to increased consumer awareness and demand for fresh, locally produced fruit.

New research published in journal HortScience examined whether where black raspberries are grown influences the antioxidant level in the berries.

To estimate variability in phytonutritional quality of black raspberries, the researchers studied 19 samples representing four common Midwestern black raspberry cultivars harvested from eight production sites. Samples were frozen within 24 hours of harvest in on-farm, conventional freezers. These materials were transported in their frozen state to the Ohio Agricultural Research and Development Center and stored in 100-g batches at 29 degrees Celsius until analyzed. The team then evaluated each of the cultivars to determine antioxidant levels.

“Inverse relationships among black raspberry samples suggested that site differences may be partially attributable to fruit ripeness at harvest,” the researchers wrote. “Relationships among these parameters versus regional differences in soil temperatures were also significant, but weak.”

Variation in fruit phytonutrient contents related to growing location may prove important in future health-related studies or clinical applications, as well as affecting nutritional benefits to consumers.

The study also contains recommendations for black raspberry growers and marketers, indicating that phytonutrient levels may be affected by genetic, cultural and/or environmental factors.

GI, Fiber, Whole-Grain Intake Not Associated With BMI

According to a recent study, dietary glycemic index (GI), glycemic load (GL), and fiber and whole-grain intakes in healthy, free-living adolescents were not relevant to the development of percentage of body fat or body mass index (BMI) during puberty (Am. J. Epidemiol. 2009 169:678-682) (DOI:10.1093/aje/kwn388). Linear mixed-effects regression analyses were performed in 215 participants from the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study who possessed weighed three-day dietary records and anthropometric data at puberty onset and over the subsequent four years (1988 to 2007). Neither changes in dietary GI, GL, fiber intake nor whole-grain intake were associated with concurrent changes in percentage of body fat throughout puberty per standard deviation (SD) increase in GI (P=0.8); –0.01 per SD increase in GL (P=0.9); 0.02 per SD increase in fiber intake (P=0.9); and 0.09 per SD increase in whole-grain intake (P=0.5). No concurrent associations were observed between these dietary factors and BMI SD scores. Associations of dietary GI with percentage of body fat and BMI SD score differed between overweight and normal-weight adolescents.

Strawberry Aroma Linked to Consumer Preference

WINTER HAVEN, Fla.—Researchers at University of Florida's Gulf Coast Research and Education Center in Wimauma, Florida, and the USDA Agricultural Research Service (ARS) have determined that the aroma of fresh strawberries is linked directly to consumer preference.

Lead author Anne Plotto of the USDA-ARS said researchers evaluated five selections and one cultivar of the University of Florida breeding program as well as two new cultivars from Australia (‘Rubygem’ and ‘Sugarbaby’). The sensory evaluation showed that tasters determined a high variation among Florida strawberries in terms of flavor, sweetness and tartness preferences.

“This study shows that aroma volatiles and sugar levels must be balanced to ensure a flavor appealing to consumers,” she said. “Although germplasm strongly influenced volatile composition and perceived flavor, harvest date and season were also found to be an important factor influencing strawberry composition. Genotypes with low flavor ratings were most often judged as "not sweet enough" by the panelists, thus linking flavor to sweetness preference.”

U.S. Shiitake Market Growing

COLUMBA, Mo.—A new study from University of Missouri reveals shiitake mushrooms are the third most-popular mushroom species in the United States due in part to an increase in demand for the fungi’s nutritional and health benefits.

Researchers Michael A. Gold, Mihaela M. Cernusca and Larry D. Godsey surveyed 104 U.S. shiitake producers about production and marketing of the mushrooms. Growers chose shiitake because of their nutritional benefits as well as being an environmentally friendly crop. Eighty-eight percent of the growers who responded produced organically, while 40 percent were certified organic by the USDA.

The study, published in journal HortTechnology, also found that 75 percent of respondents sold shiitake to restaurants; 69 percent sold to farmers markets; and 61 percent sold through on-farm outlets. Wholesale prices reported by respondents were between $5 and $7 per pound. Nearly 40 percent of respondents noted an increase in demand over the past five years.

Vegan Before 6 p.m.

The New York Times’ food writer, Mark Bittman, recently wrote a book, “Food Matters: A Guide to Conscious Eating With More Than 75 Recipes” about his diet plan that keeps him healthy and helped him lose 35 pounds: a vegan diet until 6 p.m.—after that, anything is allowed.
