Increase in oral dose of intrinsic factor preparations from hog stomach or active gastric materials from humans, with a constant oral dose of vit. B12, up to a certain point, increases the intestinal absorption of vit. B12as measured by the hepatic uptake of Co60-B12. However, further increase in the amount of intrinsic factor may be devoid of any enhancing effect or even result in decreased absorption of B12in the intestine. The latter might be due to an excessive binding of B12to the non-absorbed fraction of the intrinsic factor preparation, having high binding capacity for vit. B12. |
