Summary

This pilot study tests whether taking a commercial probiotic daily for 4 weeks can increase blood levels of folate, vitamin B12, and vitamin B6 in healthy women aged 18–40. Participants will take either one or two capsules per day and provide blood and stool samples. The goal is to see if probiotics can help improve nutrient levels without the need for supplements.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Probiotic capsule containing multiple bacterial strains (e.g., Bifidobacterium, Lactobacillus)
What this could lead to: If it works, this could point toward a simple, non-drug way to improve nutrient levels in women of childbearing age.
What could go wrong: This is a small, early pilot study with only 82 participants. It may not show a clear effect, and results may not apply to women with nutrient deficiencies or other health conditions.
