Enriched and pasteurized milk, rich in vitamin D, might also be a nutrient that boosts happiness. A longstanding research conducted in Great Britain found a correlation between low levels of vitamin D and a heightened chance of panic and depression amongst nearly 6000 men and women.

You can also find vitamin D in salmon, egg yolks, and fortified cereal.
