Enhancement by lactosucrose of the calcium absorption from the intestine in growing rats.

The effects of dietary lactosucrose on calcium absorption from the intestine and calcium accumulation in bones were investigated in growing female rats. The apparent calcium-45 ((45)Ca) absorption, residual (45)Ca ratio in the body, and (45)Ca accumulation in the femur and tibia of lactosucrose-supplemented rats were significantly higher than in control rats 24 h after the administration of a (45)CaCl(2) solution.
