The GRAS affirmation recommends a safe usage level of 0.2% to 1.25%.
Verdure Sciences’ (Noblesville, IN) bioavailable Longvida curcumin has been self-affirmed GRAS for food and beverages by an independent scientific panel. The GRAS affirmation recommends a safe usage level of 0.2% to 1.25%.
Longvida showed no toxicity at 720 mg/kg body weight per day, the highest dose tested-and 100 times the dosage range recommended for human use-Verdure reports. This dose was tested as part of a 90-day, subchronic toxicity study, which was included in the GRAS assessment. Verdure adds that Longvida’s GRAS affirmation is based on more than a dozen clinical, preclinical, and safety studies, along with supportive studies on curcumin by numerous government and university research groups.
“The substantial evidence supporting the safety and efficacy of Longvida, particularly at low-dose levels, makes it an ideal ingredient for food and beverage products,” says Blake Ebersole, technical director.
Among the uses Verdure suggests for Longvida in food and beverage are geriatric and healthy-aging nutrition beverages; beverages supporting cognitive, gastrointestinal, liver, and joint health; sports nutrition beverages; fruit and vegetable juices; nutrition bars and baked goods; and milk products, including those for weight management.
The GRAS determination also covers Longvida SD, a water-dispersible form of Longvida.
