Sea lettuce (Ulva spp.) is the only green sea vegetable we sell, and it actually does resemble a small head of lettuce when in the water. Sea lettuce grows abundantly in the tidal and upper subtidal zones. It is thin and fragile, being only two cells thick, and it expresses various hues of vibrant green as it matures.
Sea lettuce is rich in sulfur compounds, which impart a bitter flavor and a distinctive aroma, but which also provide it with a host of potential health benefits. These include supporting liver function and aiding in fighting age-related diseases. Sea lettuce is notable for containing more minerals, especially calcium, iron, potassium, and magnesium, than many of our other sea vegetables. Sea lettuce is about 15% protein by dry weight and it has moderate iodine content compared to other sea vegetables. Its vibrant green color comes from chlorophyll, the same pigment found in land plants..
Sea lettuce is good in soups or salads. Experiment by tearing or cutting the whole dry leaves with scissors into your favorite dish. We also offer sea lettuce in flake and powder form to add to salads and smoothies.
