Background: Vitamin C (ascorbic acid, ascorbate) has been shown to enhance neurite outgrowth, promote fi broblast adhesion during wound healing, and reduce xenobiotic-induced leukocyte hyperactivity and
infl ammatory damage. In this study, a comparison was made between Ester-C® and PureWay-C™ on these various cellular activities.
Material/Methods: PC12 cells were stimulated to form neurites with nerve growth factor, NIH 3T3 fi broblasts were seeded on fi bronectin and H9 T-cells were stimulated to aggregate with the pyrethroid pesticide
bifenthrin. The rate of neurite formation, fi broblast adhesion and T-cell homotypic aggregation was then measured in the absence and presence of various formulations of vitamin C including Ester-C® and PureWay-C™.
Results: With PureWay-C™ treatment, 12% of PC12 cells extended neurites within one hour of treatment and 45% of the cells extended neurites by hour nine. With Ester-C®, 0% and 15% extended neurites at one and nine hours, respectively. NIH-3T3 fi broblast adhesion to fi bronectin was enhanced
by 4.7-fold with a 30 minute PureWay-C™ treatment while Ester-C® increased fi broblast adhesion by only 1.5 fold. Further, PureWay-C™ reduced pesticide-mediated T-cell homotypic aggregation
by 83% within 30 minutes of treatment while the reduction seen with Ester-C® was only 33%.
Conclusions: These data confi rm the previous observations that vitamin C supplementation can promote neurite outgrowth, increase fi broblast adhesion and reduce xenobiotic induce immunocytes aggregation.
More importantly, these data show that PureWay-C™ has a faster and greater benefi cial effect on these parameters when compared to other vitamin C formulations.
