The nutritional content of lettuce varies across varieties. Almost all lettuces contain a significant amount
of vitamin A, along with small amounts of vitamin C and iron.

Health Benefits

Bone Strength

Lettuce is a source of vitamin K, which helps strengthen bones. Consuming adequate amounts of vitamin
K can also reduce your risk of bone fracture.

Hydration

Water makes up over 95% of raw lettuce. As a result, eating lettuce hydrates the body. Although drinking
liquids is necessary, water in foods can also significantly contribute to hydration.

Improved Vision

Lettuce is a source of vitamin A, which plays a role in eye health. Vitamin A can reduce a person’s risk of
cataracts. Vitamin A also helps prevent macular degeneration.

Improved Sleep

Extracts of multiple lettuce types have also been shown to promote sleep. Until further research is
conducted, it’s unknown if lettuce in its natural form can produce a similar effect.
