Thorne’s B-Complex #12 brings together all eight essential B vitamins—thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, biotin, and pantothenic acid—plus choline, in forms your body can use straight away. With active B12 (methylcobalamin) and folate (5-MTHF), this formula supports energy-yielding metabolism, helps reduce tiredness and fatigue, and contributes to normal psychological and nervous system function.

Each capsule is designed to fit easily into your daily routine, helping you maintain normal red blood cell formation, immune function, and healthy skin. Whether you’re looking to support your focus, energy, or overall wellbeing, B-Complex #12 is a simple way to help your body thrive every day.

Thorne's B-Complex #12 includes the bioavailable forms of vitamin B12 (methylcobalamin) and folate (5-MTHF), which are more readily absorbed and utilised by the body compared to their less-bioavailable counterparts, such as cyanocobalamin and folic acid. These active forms bypass the conversion steps required by non-active forms, ensuring that your body receives the full benefits of these vital nutrients, which are essential for energy production, red blood cell formation, and neurological function. Additionally, being free from yeast makes this supplement an excellent choice for individuals with yeast sensitivities or those who prefer to avoid yeast-derived ingredients, ensuring a cleaner, more easily tolerated formula. With Thorne's B-Complex #12, you get a superior, high-quality supplement that supports optimal health with maximum efficacy.
