Two things separate this from a supermarket B complex, and both are on the label.The first is that the B vitamins are in activated form, meaning the body can use them as they arrive rather than having to convert them first. The headline inclusion is Quatrefolic®, a patented folate that is already in the active state, which matters if you are one of the many people whose folate metabolism carries a common genetic variation.The second is liposomal delivery. Each molecule is encapsulated in a phospholipid microsphere that shields it through the digestive tract, and the phosphatidylcholine that forms that bilayer is itself a useful nutrient rather than an inert wrapper.One capsule per day. Thirty capsules.Brown rice flour, vegetable stearate, phosphatidylcholine and silica in a clear vegetable capsule. No known allergens, no sugar, no gluten, no artificial flavours or preservatives, which is a genuinely short list for a B complex.
