Potential Benefits of Raw Zucchini Juice

Drinking raw zucchini juice may offer several potential health benefits:


Zucchini has a water content of around 95%. This makes zucchini juice a great way to hydrate the body.

Vitamin C

With 17% of the DV of vitamin C in just 1 cup, zucchini juice can help you meet your daily vitamin C needs. Vitamin C is important for immune health and plays a role in collagen production.


Zucchini contains antioxidants like lutein and zeaxanthin which help protect your cells from damage by unstable molecules called free radicals.


Some of the antioxidants in zucchini may help reduce inflammation in the body when consumed regularly.

Vision Health

The antioxidants lutein and zeaxanthin found in zucchini have been linked to better eye health and lower risks of age-related eye diseases.

Heart Health

Animal studies have found the antioxidants in zucchini juice may help lower blood pressure and cholesterol levels, reducing heart disease risk.

Weight Loss

The low calorie, high water content of zucchini juice may help fill you up without adding a lot of calories, which can aid weight loss.

Potential Downsides of Zucchini Juice

While zucchini juice has some benefits, there are a few downsides to consider as well:

Lower Fiber Content

Juicing zucchini removes the pulp and skin, which is where much of the fiber is contained. The fiber content is lowered from 1 gram per cup of raw zucchini to just 0.5 grams in an equivalent amount of juice.

Nutrient Loss

Some vitamins like vitamin C are stable during juicing, but others like vitamin A can degrade when exposed to heat, light and air. Juicing may lead to some nutrient loss.

Quickly Absorbed Sugars

The juicing process removes the pulp, making the sugars in zucchini juice more quickly absorbed. This can potentially lead to spikes in blood sugar.


Zucchini contains oxalates, which can contribute to kidney stone development in some people when consumed in excess.

Frequently Consumed with Fruit

Many zucchini juice recipes include fruit like apples or lemon. This increases the sugar content and calorie count of the juice.

Who May Want to Avoid It

While zucchini juice is likely safe for most people, those with certain medical conditions may want to avoid drinking it regularly:

Condition Reason to Avoid
Kidney stones Zucchini contains oxalates that can contribute to kidney stone formation in susceptible people.
Diabetes The sugars in zucchini juice are absorbed more quickly without the fiber, which can spike blood sugar levels.
Low blood pressure Zucchini juice may lower blood pressure, which can be harmful for those with hypotension.
Digestive issues The high fiber content of whole zucchini can exacerbate some digestive issues. Juicing removes this fiber.

How to Juice Zucchini

If you want to try making your own zucchini juice at home, follow these simple steps:

  1. Wash the zucchini thoroughly and trim off both ends.
  2. Chop the zucchini into sections small enough to fit through your juicer feed tube.
  3. Juice the zucchini pieces, collecting the juice in a cup or pitcher.
  4. Drink the raw zucchini juice right away or store in an airtight container in the refrigerator for up to 3 days.

Consider pairing zucchini with low sugar fruits like lemon or lime if you want to add some sweetness. Herbs like mint or parsley can also complement the flavor.

The Bottom Line

Raw zucchini juice provides vitamin C, antioxidants, and hydration, which may benefit your immune system, heart health, vision, inflammation levels and weight loss efforts. However, juicing removes important fiber and may negatively impact blood sugar levels.

In moderation, zucchini juice can be part of a healthy diet for most people. But those with certain conditions like kidney stones or diabetes may want to avoid drinking large amounts.

Make sure to enjoy zucchini juice as part of an overall balanced diet with plenty of whole vegetables and fruits. Focus on getting nutrients from whole food sources as much as possible.
