The crunch

(47Ca = radioactive calcium so it can be traced)

http://ajcn.nutrition.org/content/22/4/381.abstract

3) In the majority of patients the plasma levels of 47Ca were lower during the intake of sodium fluoride than in the control studies indicating decreased absorption of 47Ca. The average decrease of the 47Ca plasma levels was 30% and the average decrease in 47Ca absorption, determined from fecal 47Ca excretions, was 23%.

which from the conclusion is not what they were anticipating . . .

4) These studies have shown that the intestinal absorption of calcium and the calcium balances did not improve during an intake of 20.6 mg sodium fluoride/day given for 22-42 days.

somewhat of an understatement
