Swanson Ultra set the standard for advanced B-vitamin supplementation with the original Activated B-Complex. Now by popular request, we've developed a lower-potency version of our best-selling formula that is focused on optimized bioavailability. Both formulas feature the same advanced forms of B-vitamins, including Benfotiamine (thiamin/vitamin B1), Pyridoxal 5-phosphate (P5P/vitamin B6), Methylcobalamin (vitamin B12), patented Pantesin (pantethine) and revolutionary Quatrefolic 5-methyltetrahydrofolic acid (folate). These superior forms offer higher bioavailability for reliable supplementation.
