Abstract
ZHANG and COLLEAGUES, Lady Davis Institute for Medical Research, McGill University, and Jewish General Hospital, 3755 Cote Sainte Catherine, Montreal, QC H3T 1E2, Canada. l.hoffer@mcgill.ca conducted a double-blind clinical of vitamin C and D provision to assess whether these could improve the mood state of acutely hospitalized patients.
Background
Hypovitaminosis C and D are highly prevalent in acutely hospitalized patients, but the clinical significance of these biochemical abnormalities is not known. Because deficiencies of vitamin C and D have been linked to psychological abnormalities, vitamin C or D provision could improve the mood state of acutely hospitalized patients.
Methodology
Double-blind clinical trial of the effect of vitamin C (500 mg twice daily) or vitamin D (1000 IU twice daily) on mood, as assessed with a validated instrument, the Profile of Mood States.
Results
Vitamin C therapy increased plasma (P < 0.0001) and mononuclear leukocyte (P = 0.014) vitamin C concentrations and was associated with a 34% reduction in mood disturbance (P = 0.013). Vitamin D therapy increased plasma 25-hydroxyvitamin D concentrations (P = 0.0004), but had no significant effect on mood.
Conclusion
Treatment of hypovitaminosis C improves the mood state of acutely hospitalized patients.
