Carrot juice is extracted from whole carrots and extremely nutritious.

It not only provides potassium and vitamin C but also is very rich in provitamin A. Drinking carrot juice is thought to boost immunity and improve eye and skin health, among other benefits.

1. Highly nutritious

Carrot juice is low in calories and carbs while packing numerous nutrients. One cup (240 mL) contains:

  • Calories: 96
  • Protein: 2 grams
  • Fat: less than 1 gram
  • Carbs: 22 grams
  • Sugars: 9 grams
  • Fiber: 2 grams
  • Vitamin A (as provitamin A): 255% of the Daily Value (DV)
  • Vitamin C: 23% of the DV
  • Vitamin K: 31% of the DV
  • Potassium: 15% of the DV

Carrot juice also provides the carotenoid pigments lutein and zeaxanthin, which act as antioxidants in your body. Antioxidants fight unstable molecules called free radicals.

The main carotenoid in carrot juice is beta carotene, which is responsible for carrots’ orange color. Your body converts it into the antioxidant vitamin A.

2. May improve eye health

Carrot juice contains high amounts of nutrients that benefit your eyes.

Specifically, 1 cup (250 ml) of carrot juice packs over 250% of the DV for vitamin A, mostly in the form of provitamin A carotenoids like beta carotene.

Vitamin A is vital for eye health. Several studies associate the intake of fruits and vegetables that contain provitamin A with a decreased risk of blindness and age-related eye diseases.

3. May boost immunity

Carrot juice may give your immune system a boost.

Both vitamins A and C found in carrot juice act as antioxidants and protect immune cells from free radical damage.

Additionally, this juice is a rich source of vitamin B6, providing over 30% of the DV in 1 cup (240 mL). Not only is vitamin B6 necessary for an optimal immune response, but deficiency in it is also linked to weakened immunity.

4. May provide anticancer effects

Test-tube studies suggest that certain compounds in carrot juice may protect against cancer.

Specifically, polyacetylenes, beta carotene, and lutein from carrot juice extract may be effective against human leukemia cells.

One test-tube study found that treating leukemia cells with carrot juice extracts for 72 hours led to cancer cell death and stopped the cell growth cycle.

5. May improve blood sugar control

Drinking small amounts of carrot juice may help lower blood sugar levels.

In particular, studies in rats with type 2 diabetes show that fermented carrot juice decreases blood sugar and improves other related markers. That’s because the juice contains probiotics, which are beneficial bacteria that affect gut bacteria associated with diabetes.

Another rodent study found that purple carrot juice boosts blood sugar control due to the anti-inflammatory effect of its anthocyanin pigments.

6. May improve skin health

The nutrients in carrot juice may be particularly beneficial for skin health.

One cup (250 ml) of carrot juice provides over 20% of the DV for vitamin C, a water-soluble nutrient necessary for collagen production. This compound is the most abundant fibrous protein in your body, and it provides elasticity and strength to your skin.

Additionally, vitamin C acts as an antioxidant to protect your skin from free radical damage.

7. May boost heart health

Carrot juice may help reduce risk factors for heart disease.

First, carrot juice is a good source of potassium, a mineral that plays an important role in proper blood pressure regulation. A high potassium diet has been shown to protect against high blood pressure and stroke.

Antioxidant compounds in carrot juice may also benefit your heart.

8. May protect your liver

The carotenoids in carrot juice are thought to promote liver health.

Several studies indicate that the anti-inflammatory and antioxidant effects of carotenoids protect against non-alcoholic fatty liver disease (NAFLD).

NAFLD occurs when fat accumulates on your liver, typically as a result of poor diet, excess weight, or obesity. It may eventually progress to liver scarring and lasting damage.

The bottom line

Carrot juice is incredibly nutritious, providing potassium, several carotenoids, and vitamins A, C, and K.

Drinking this veggie juice may help improve eye health, boost your immune system, and strengthen skin. However, more extensive human research is needed.

Since it contains natural sugars, you may want to drink it in moderation.
