Safety and Pharmacokinetics of Orally Administered Strontium L-Lactate in Healthy Adults
A study testing Strontium L-lactate in people with Low Bone Density and Osteopenia, run by BioLink Life Sciences, Inc. at 1 site in United States.
Trial summary
No clinical trials have evaluated strontium L-lactate (SrLac), the strontium salt of the L-enantiomer of lactic acid. Therefore, this clinical study was conducted to obtain general safety and pharmacokinetic (PK) information following acute oral intakes of three doses of SrLac by healthy adults.

About this study
No clinical trials have evaluated strontium L-lactate (SrLac), the strontium salt of the L-enantiomer of lactic acid. Therefore, this clinical study was conducted to obtain general safety and pharmacokinetic (PK) information following acute oral intakes of three doses of SrLac by healthy adults.

Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Strontium L-lactateDietary supplement
Also called SrLac
The Study Product was a highly pure form of SrLac, the strontium salt of L-lactic acid. SrLac was manufactured in compliance with current Good Manufacturing Practices. SrLac was thoroughly tested and met rigorous purity specifications. It was free from contamination by D-lactic acid and trace metals known to harm human health.
| Study group | Role | What they receive |
|---|---|---|
| Strontium dose of 170 mg | Active comparator | The Sponsor provided each 170 mg dose of strontium as strontium L-lactate dry powder packaged in individual vials. The powder was prepared for consumption by adding 10 mL of distilled water to the vial and stirring until dissolution was complete. This liquid was then poured into an administration cup. An additional 10 mL of distilled water was used to rinse the remaining SrLac into the administration cup. Then 80 mL of distilled water was added directly into the administration cup. Following consumption of the 100 mL solution of SrLac, another 100 mL of distilled water was added into the administration cup, swirled, and consumed by the subject. Receives: Dietary Supplement: Strontium L-lactate |
| strontium dose of 340 mg | Active comparator | The Sponsor provided each 340 mg dose of strontium as strontium L-lactate dry powder packaged in individual vials. The powder was prepared for consumption by adding 10 mL of distilled water to the vial and stirring until dissolution was complete. This liquid was then poured into an administration cup. An additional 10 mL of distilled water was used to rinse the remaining SrLac into the administration cup. Then 80 mL of distilled water was added directly into the administration cup. Following consumption of the 100 mL solution of SrLac, another 100 mL of distilled water was added into the administration cup, swirled, and consumed by the subject. Receives: Dietary Supplement: Strontium L-lactate |
| Strontium dose of 680 mg | Active comparator | The Sponsor provided each 680 mg dose of strontium as strontium L-lactate dry powder packaged in individual vials. The powder was prepared for consumption by adding 10 mL of distilled water to the vial and stirring until dissolution was complete. This liquid was then poured into an administration cup. An additional 10 mL of distilled water was used to rinse the remaining SrLac into the administration cup. Then 80 mL of distilled water was added directly into the administration cup. Following consumption of the 100 mL solution of SrLac, another 100 mL of distilled water was added into the administration cup, swirled, and consumed by the subject.

Questions about this trial
What is this clinical trial studying?
A study testing Strontium L-lactate in people with Low Bone Density and Osteopenia, run by BioLink Life Sciences, Inc. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
iAUC-0.25-12h (time frame: 0.25 hour pre-dosing to 12 hours post-dosing on each day of dosing). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2018; AzTrials last refreshed its copy on 8 Nov 2026.
