Why it is included
Niacinamide is included as part of Prebiotic's skin barrier nutrients active ingredients.
Niacinamide, also known as vitamin B3, supports cellular energy metabolism and skin barrier function. It is involved in pathways linked to epidermal renewal, barrier resilience, and antioxidant defence. Within a gut–skin formula, niacinamide helps support the nutritional needs of healthy skin while the fibre blend supports gut balance from within.
