Carleton University
82 participants
Nov 28, 2025
INTERVENTIONAL
Conditions
Summary
The goal of this pilot study is to determine if taking a commercially available probiotic product can influence levels of vitamins B12, B6 and folate after a 4-week supplementation period in reproductive-aged women without any micronutrient deficiencies. The main question it aims to answer is: • Does a probiotic product influence blood folate, vitamin B12 and B6 levels in reproductive-aged women when it is taken regularly for 4 weeks? Participants in this clinical trial will consume the probiotic product containing multiple probiotic strains regularly for 4 weeks. One group will consume one capsule per day at a particular dose, and the second group will consume two capsules per day at another dose. Participants will also have to: * Attend two in-person visits with a researcher: at enrolment (baseline), and endline (day 28/4 weeks) * Provide a blood sample at baseline (day 0) and endline (day 28/4 weeks) * Provide two stool samples (following each in-person visit) * Complete an online "study diary" every two weeks for 4 weeks (2 study diaries) * Complete two sets of online questionnaires (following each in-person visit) * Complete two sets of dietary assessments (following each in-person visit)
