Abstract
|
|
|
When about 300 mg of L-ascorbic acid was given intravenously to the adults saturated with the vitamin, the increased blood level returned to almost the original level in 3 hours. Also the amounts of the vitamin absorbed by the tissue cells and metabolized in the body or excreted into the gastrointestinal tract were found to average 74.1mg in 3 hours.
When about 300 mg of L-ascorbic acid was given intravenously twice at intervals of 3 hours, an average of 101 mg of the vitamin was absorbed by the tissue cells and metabolized in the body or excreted into the gastrointestinal tract in 6 hours. When the vitamin was given orally to the saturated adults, the absorption rate increased as the test does increased. When large amounts (3.0 gm) of the vitamin were given, the absorption rate reached the maximum. The maximum absorption in 6 hours was estimated as 681 mg of the vitamin.
