In a study on two groups of soldiers, one supplemented with high doses of vitamins of the B coumplex and ascorbic acid, the other receiving placebos, the following observations were made:

There were no statistically significant differences between the two groups in regard to urinary nitrogen excretion, blood glucose, hemoglobin, creatinine excretion, and 17-ketosteroid excretion. Urinary and blood ascorbic acid showed the expected differences between the treatment groups, with very high values in the supplemented group. A statistically significant increase in oxidized ascorbic acid excretion occurred in both groups during cold exposure.

The fall in eosinophil count during forced marches was statistically significantly greater in the supplemented than in the control group.

There was a statistically significantly greater fall in body weight in the supplemented group during the course of the experiment.

A group of psychological tests performed at intervals during the study did not reveal any differences between the two treatment groups.
