Criteria and recommendations for vitamin C intake.
TL;DR: The tolerable upper intake level, the highest daily level of nutrient intake that does not pose risk or adverse health effects to almost all individuals in the population, is proposed to be less than 1 g of vitamin C daily.
Journal ArticleDOI
Glucose Transporter Isoforms GLUT1 and GLUT3 Transport Dehydroascorbic Acid
Steven C. Rumsey,Oran Kwon,Guo Wei Xu,Charles F. Burant,Ian A. Simpson,Mark Levine,Mark Levine +6 more
TL;DR: GLUT1 and GLUT3 isoforms are the specific glucose transporter isoforms which mediate DHA transport and subsequent accumulation of AA according to Xenopus laevis oocyte expression system studies.
Journal ArticleDOI
Absorption, transport, and disposition of ascorbic acid in humans
Steven C. Rumsey,Mark Levine +1 more
TL;DR: Elucidation of mechanisms that modulate the delivery of ascorbate to tissues and its utilization under different metabolic conditions will be invaluable for making recommendations for asCorbate ingestion.
Journal ArticleDOI
Dehydroascorbic Acid Transport by GLUT4 in XenopusOocytes and Isolated Rat Adipocytes
Steven C. Rumsey,Rushad Daruwala,Hadi Al-Hasani,Mary Jane Zarnowski,Ian A. Simpson,Mark Levine +5 more
TL;DR: It is indicated that the insulin-sensitive transporter GLUT4 transports DHA in both rat adipocytes and Xenopus oocytes, and Alterations of this mechanism in diabetes could have clinical implications for ascorbate utilization.
Journal ArticleDOI
Ascorbate recycling in human neutrophils: Induction by bacteria
TL;DR: Ascorbate recycling occurs in human neutrophils but not in microorganisms, it may represent a eukaryotic defense mechanism against oxidants with possible clinical implications.
