^In a randomized double-blinded, placebo-controlled study of 112 healthy volunteers subjects, taking the GNC vitamin and mineral blend for 6 weeks experienced significant improvements in serum levels of certain key nutrients compared to a placebo and a leading multivitamin formula based upon multivariate statistical analysis of a group of B vitamins (thiamin, niacin, riboflavin, pantothenic acid, biotin, folic acid and vitamins B-6, and B-12) and key antioxidants and carotenoids (a group of beta-carotene, alpha-tocopherol, selenium lutein and lycopene). Statistical improvements in SF- 36 Vitality and Mental Health Score were also overserved compared to placebo.
