To observe the absorbability of the dietary V-C in the body, the study was carried on the V-C concentration in the blood and urine after meal. The subjects, two of the nineteen years old boys were fed spinach, pickled radishes, tomato or vitamin C powder which were contained as much 200 mg as V-C respectively. The results obtained are summarized as follows,
1) Total V-C concentration in the blood showed the highest value at 3-4 hours after meal.
2) The highest V-C value in the blood was 1.89+0.13 mg/dl and it was in the saturated condition where as the total V-C excretion in the urine was about 47mg/day.
3) It seemed that the gut has a limitationn on the V-C absorption when a large amount of V-C was ingested.
