Bioavailability of chondroitin sulfate sodium from bovine and vegetarian sources in healthy adults.

This is a two arm, randomised, double-blind, single-dose, crossover study which includes two study arms separated by a washout period of at least seven days. At each visit, participants will consume one of the following: A: Vegetarian chondroitin sulfate sodium (2400 mg) - taken as an oral capsule B: Bovine chondroitin sulfate sodium (2400 mg) - taken as an oral capsule By the end of the study, participants will have received both study interventions. Each study arm spans 48 hours. Participants must consume their intervention as quickly as possible with 200 mL of water. Interventions will be delivered face-to-face by a research associate who has experience in participant management during clinical studies. Participants will be supervised by a member of the research team to monitor adherence. Participants will remain on site for the initial 14 hours of each study arm. There are additional timepoints at 24, 36 and 48 hours. Participants will leave the facility after the 14-hour timepoint and will return at the 24-hour, 36-hour and 48-hour timepoints. All visits will take place at the Bioeconomy Science Institute (BSI) clinical research facility.
