Safety and Pharmacokinetics of Orally Administered Strontium L-Lactate in Healthy Adults

Purpose: The aim of this clinical study was to obtain safety and pharmacokinetic information following acute oral intakes of three ascending doses of strontium L-lactate by healthy adults. Subjects and methods: Ten healthy men and women, mean age 43 ± 2 years, ingested one of three ascending doses of strontium L-lactate (SrLac) once per week for three weeks in succession. Fasting blood collections were performed pre-dose and 1, 2, 3, 4, 5, 6, 8 and 12 hours post-dose for determination of serum strontium at each interval.
