what is a quality vitamin b complex supplement?

[iceprincess]

how do you guys get a good quality consumption of b-vitamins? I heard nutritional yeast is a great to way to increase your intake of b-vitamins but a lot of them come with fortified vitamins the non-synthetic yeast is very expensive. is there any supplement or foods you guys take to increase it?

All wholegrains are filled with b vitamins, legumes, nuts, seeds also have decent amounts. For folate (B9) add some extra greens and lentils and for B12 either animal products or supplements (fortified foods are not sufficient with this one)
