Which vitamin's dietary sources include meats, fish, poultry, and grains?

Explanation:
Niacin (vitamin B3) is found in a wide range of foods, with meats, fish, and poultry being good natural sources and grains often fortified or enriched to boost niacin content. This combination—animal proteins plus fortified grains—best fits the dietary sources listed for this vitamin. Niacin can also be made in the body from tryptophan, so foods containing tryptophan contribute indirectly, but the primary sources described align most clearly with niacin.
