The three most essential B vitamins are; Thiamin(B1), Riboflavin(B2) and Niacin(B3). Without these, you could be left feeling slow and sluggish as they convert food into adenosine triphosphate (ATP).
Thiamin rich foods include lentils, nuts, seeds, tuna and pork.
Riboflavin is found in leafy green vegetables, tomatoes, almonds and eggs.
Niacin is found in the highest concentrations in animal protein such as beef, pork, chicken and fish. Also found in beans.
