http://www.nal.usda.gov says that 70 grams (~ a can) of "Fish, tuna, light, canned in water, drained solids" has:

- 0.022 mg of Thiamin; RDA is 1.4 mg

- 0.052 mg of Riboflavin; RDA is 1.2 mg

- 9.296 mg of Niacin; RDA is 16 mg

- 0.150 mg of Pantothenic acid; RDA is 5 mg

- 0.245 mg of Vitamin B-6; RDA is 1.3 mg

- 2.09 mcg of Vitamin B-12; RDA is 2.4

So while tune does have enough of some B vitamins, it does not have enough of the others.
