Is romaine lettuce good for juicing?


Romaine lettuce has become an increasingly popular vegetable to use for juicing. With its mild flavor and high nutrient content, romaine makes a great base for green juices and juice cleanses. But is romaine lettuce actually a good choice for juicing? In this article, we’ll take a look at the benefits and downsides of using romaine lettuce in your juices.

Nutritional Benefits of Romaine Lettuce

Here are some of the key nutrients found in romaine lettuce and why they make it a healthy option for juicing:

Vitamin A

Romaine lettuce is an excellent source of vitamin A, providing 148% of the RDI in just one cup (47 grams) of shredded leaves. Vitamin A is important for immune function, vision, and cell growth.

Vitamin K

Romaine lettuce contains 136% of the RDI for vitamin K in one cup. This vitamin plays a key role in blood clotting and bone health.


Also known as vitamin B9, folate is essential for making red blood cells and DNA. A cup of romaine lettuce provides about 64% of the RDI for folate.

Vitamin C

While not as high in vitamin C as citrus fruits, romaine still supplies 17% of the RDI per cup. Vitamin C acts as an antioxidant and helps with iron absorption.


With 12% of the RDI in a cup, romaine lettuce can help you meet your daily potassium needs. Potassium supports heart health, metabolism, and muscle function.


Romaine lettuce provides 5% of the RDI for iron in one cup. As a component of hemoglobin, iron is important for delivering oxygen throughout the body.

Other Nutrients

Romaine lettuce also contains small amounts of calcium, magnesium, phosphorus, zinc, selenium, and B vitamins.

Potential Downsides of Juicing Romaine Lettuce

Although romaine lettuce offers some beneficial nutrients, there are a few potential downsides to consider when using it for juicing:

Low in Calories

With only 8 calories per cup, romaine lettuce is very low in calories. This can be an advantage for weight loss but may not provide enough energy for some people.

Low in Fiber

Juicing romaine lettuce removes the majority of its fiber content. Each cup of shredded leaves has 1.2 grams of fiber. Adequate fiber is important for digestion and heart health.

High in Nitrates

Romaine lettuce tends to be higher in nitrates than some other lettuces. Nitrates can convert to nitrites in the body and have been linked to an increased risk of certain cancers. However, the amount provided by romaine is unlikely to be a health risk for most people.

Risk of Contamination

As a leafy green, romaine lettuce is at a higher risk of contamination from bacteria, viruses, or parasites compared to vegetables with peelable skins. Be sure to wash romaine thoroughly before juicing.

How to Juice Romaine Lettuce

If you want to give romaine lettuce juicing a try, here are some tips:

Wash Thoroughly

Rinse lettuce under running water to remove any dirt or debris. Soak the leaves in cold water for 5 minutes, then rinse again. This helps remove sand and bacteria.

Remove Core

Cut the core out of the romaine lettuce heads before juicing. The crunchy core is difficult for most juicers to process.

Chop Leaves

Chop romaine leaves into 2-3 inch pieces to help them feed into the juicer chute easily. Roll leaves together to create a compact bundle.

Combine with Fruit

Balance out the green veggie taste by mixing romaine with sweet fruits like apples, pears, citrus, pineapple, or mango. Aim for a ratio of at least 1 fruit for every 2 cups of greens.

Add Herbs or Spices

For more flavor, add fresh herbs like parsley, cilantro, or basil or spices like ginger or turmeric.

Drink Immediately

Consume green juices with romaine lettuce right after making them. The nutrients start to break down quickly when exposed to air.

The Best Fruits to Mix with Romaine Lettuce Juice

Here is a chart of fruits that pair well with romaine lettuce juice and why:

Fruit Benefits
Apples Add sweetness and reduce bitterness of greens. Provide fiber and vitamin C.
Oranges Citrus fruits like oranges balance out earthy flavors. High in vitamin C and antioxidants.
Pineapple Pineapple enhances the sweetness of green juices naturally. Contains bromelain, an anti-inflammatory enzyme.
Grapefruit Grapefruit adds a tangy flavor and plenty of vitamin C. Helps boost immunity.
Berries Choose berries like strawberries, blueberries, raspberries or blackberries to add color and sweetness.
Pears The mild, sweet flavor of pears works well in green juices. Provide fiber, vitamin C and antioxidants.
Kiwi Kiwi offers a tropical twist and supplies vitamin C, antioxidants and fiber.

Is Romaine Lettuce Ultimate Juicing Ingredient?

While romaine lettuce does supply key nutrients, it lacks some of the juice-boosting benefits of leafy greens like kale, spinach, or swiss chard. Romaine has a milder taste, but other greens provide more vitamins, minerals, and phytonutrients.

For the best results, rotate romaine with other leafy greens when making fresh juices. You can also combine romaine with powerhouse veggies like carrots, beets, celery, cucumber, and ginger. Herbs, spices, berries, and citrus fruits help to provide complementary flavors and additional nutrients.

Drink your green juices immediately to maximize nutrient content. And, as always, it’s important to eat a balanced diet with a variety of vegetables in addition to juicing.

The Bottom Line

Romaine lettuce can be a good addition to fresh juices, especially when combined with fruit and other vegetables. It provides a decent vitamin and mineral boost thanks to nutrients like vitamins A, K, C, potassium, and folate.

However, romaine is very low calorie and higher in nitrates than some other greens. Plus, juicing removes most of the fiber. So while nutritious, it may not be the ultimate juicing green. For best results, include romaine as part of a rotation of leafy greens and other fresh produce in your juices.
