Skin Inflammation in (Peri)Menopause: A Probiotic Intervention Proof of Concept Trial

This study will explore whether a daily probiotic drink containing Lactobacillus casei Shirota (LcS) can help improve immune function and reduce inflammation in women going through the menopausal transition. Hormonal changes during this stage of life can affect the immune system, gut health, and skin, sometimes leading to increased inflammation or conditions such as eczema, acne or rosacea. Participants will consume either a low-sugar LcS probiotic drink or a skimmed milk control drink every day for eight weeks. The study will assess markers of immune ageing, inflammation, skin health, wellbeing, and hormone levels. The results will help determine whether a safe, non-hormonal probiotic approach may support immune and skin health during the menopausal transition.
