5 Health Benefits of Drinking Carrot, Beet and Spinach Juice (+ Nitric Oxide Boost)

Have you ever wondered why some juices just feel different? You drink them, and there's this clean, bright feeling — like something good is happening. Carrot, beet, and spinach juice is one of those.

It's been one of our most popular juice recipes for years, and for good reason. These three vegetables happen to be among the most research-backed foods on the planet for cardiovascular health, immune defense, and skin quality. Juiced together, they form something greater than the sum of their parts.

Here's a look at why this combination works so well — and what the science actually says about each ingredient.

The Recipe: Fresh Juice and Powder Options

Fresh Juice Recipe (Serves 1)

• 3 medium carrots (¾ pound)
• ½ medium beet (peeled)
• 1 large handful of fresh spinach (approximately 1 cup)
• Optional: ½ apple for sweetness, 1-inch piece of fresh ginger for an anti-inflammatory boost, and/or a squeeze of lemon
• Instructions: Run everything through a juicer. Drink immediately for maximum nutrient content and nitric oxide conversion. If you let it sit, the nitrates begin to degrade.

This gives you approximately 8–10 ounces of finished juice.

Tips:

• Alternate hard vegetables (beet, carrot) with soft (spinach) when feeding through the juicer for better extraction.
• Organic beets and carrots are worth it here — these are root vegetables that absorb whatever is in the soil.
• Don't skip the ginger if you can tolerate it. The anti-inflammatory compounds in ginger pair very well with the nitric oxide benefits of beet and spinach. Homemade ginger shot! Woo-hoo!

Powder Option:

If you don't have a juicer or want the benefits of this combination in a more convenient form, BeetMax gives you concentrated beet juice powder — one of the richest sources of dietary nitrates available — that mixes easily into water or a smoothie. Pair it with BarleyMax for the spinach-equivalent green nutrients, and you have a genuinely powerful combination without the prep time.

Why These Three Vegetables?

Before we get into the benefits, it's worth appreciating what each ingredient brings to the glass.

Carrots

Carrots are loaded with beta-carotene, which your body converts to vitamin A. They also provide potassium, B6, and antioxidants that help neutralize free radicals. The natural sweetness of carrot juice makes it the perfect base, taming the earthiness of beets and the green bite of spinach.

Beets

Beets are the star of this juice from a cardiovascular standpoint. They contain exceptionally high levels of dietary nitrates, which your body converts to nitric oxide. Nitric oxide relaxes and widens blood vessels, which is how beets earn their reputation as a blood pressure food. They also bring folate, potassium, vitamin C, and a deep red color that makes this juice look as good as it functions.

Spinach

Spinach is the quiet overachiever here. It's a remarkable source of vitamin K, vitamin A, vitamin C, magnesium, iron, and manganese. It also contains lutein and zeaxanthin — two carotenoids that accumulate in the macula of the eye and protect against age-related macular degeneration. It's one of the mildest green juices, which is why it blends beautifully into this combination without overwhelming the flavor.

Nutrition Facts for Carrot, Beet and Spinach Juice

Carrot, Beet, and Spinach Juice Benefits

1. Nitric Oxide Production and Blood Pressure Support

Here's one of the biggest, most important benefits. Beets and spinach are both among the richest dietary sources of nitrates on the planet, and dietary nitrates don't just sit there. Your body converts them into nitric oxide, a molecule that signals your blood vessels to relax and widen. That's a measurable, physiological effect you can actually feel.

The landmark clinical trial on this was published in Hypertension in 2015 by Kapil, Khambata, Robertson, Caulfield, and Ahluwalia. They enrolled 68 hypertensive patients in a double-blind, placebo-controlled trial and gave half of them 250 mL of beetroot juice daily for four weeks. The result? Mean systolic blood pressure dropped by about 8 mmHg (measured three different ways, at home, in clinic, and over 24-hour monitoring) with no sign of the benefit wearing off over the study period.

So what does this mean for you? A glass of carrot, beet, and spinach juice gives you nitrates from two of the best vegetable sources available. Your saliva bacteria begin the conversion to nitric oxide within minutes of drinking it. You're not waiting weeks for this to work, as the process starts right away. Consistent daily use, as the trial showed, is where the sustained benefit builds. 

2. Healthier Skin from the Inside Out

Most people think of skin health as a topical problem, something to solve with creams and serums. But your skin reflects what's happening inside. And this juice happens to feed your skin very well.

Beta-carotene from carrots converts to vitamin A in the body, which drives skin cell turnover and repair. Vitamin A is retinol. the same compound in those expensive skin creams, working from the inside. The betalains that give beets their deep red color are potent antioxidants that protect skin cells from oxidative damage, one of the primary drivers of premature aging. And spinach contributes lutein and zeaxanthin, which research published in Skin Pharmacology and Physiology by Palombo and colleagues has linked to improvements in skin hydration, elasticity, and protection from UV-related damage. [2]

Better circulation from the nitric oxide effect shows up here, too. Wider blood vessels mean more nutrients delivered to your skin and waste products cleared away more efficiently. Good skin really does start from the inside.

3. A Big Immune Boost

A glass of this juice delivers 40% of your daily vitamin C and 25% of your daily vitamin B6, two of the three vitamins most directly tied to a functioning immune system. Vitamin C supports white blood cell production and acts as a systemic antioxidant. B6 is essential for producing the antibodies your immune system depends on. Deficiencies in either don't just leave you vulnerable; they can actively make you sick.

Spinach also brings iron, folate, vitamin K, and magnesium to the table, nutrients that support immune cell replication and the integrity of your mucous membranes, which are your body's first physical barrier against pathogens. It's a broad, complementary set of nutrients, not just one compound doing one job.

4. Liver and Detoxification Support

Your liver is working hard every day — filtering your blood, processing nutrients, neutralizing toxins, and producing bile to break down fat. All three vegetables in this juice actively support that work.

Beets contain betaine, which supports methylation, a key liver detoxification pathway. Carrots supply beta-carotene and vitamin A, which protect liver cells from oxidative damage. Spinach is rich in chlorophyll, which has been shown in research to bind to and help clear certain harmful compounds before the liver even has to process them. A 2015 review of beetroot's bioactive compounds by Clifford, Howatson, West, and Stevenson, published in Nutrients, documented hepatoprotective effects of betalains across multiple experimental models. [3]

The liver story in the research world is still developing, but from a practical standpoint, what you're putting in this juice is exactly what the liver is designed to work with: dense plant nutrition, without the processing burden.

5. More Energy

If you could drink energy, this would be it. Vitamin B6 is a key factor in how your body converts food into usable fuel. Carrots, beets, and spinach all contribute meaningful amounts. Iron from spinach supports oxygen transport in the blood — and when your cells get more oxygen, energy production follows. No caffeine, no crash.

FAQ: Benefits of Beetroot and Carrot Juice

Q: Is beet and carrot juice good for you?

Yes, and the combination is particularly effective. Carrots and beets together provide complementary antioxidants: beta-carotene from carrots and betalains from beets. They also work together on blood vessel health, with beet nitrates boosting nitric oxide while carrot antioxidants protect it.

Q: What are the benefits of beetroot and carrot juice specifically?

The main benefits are nitric oxide production, blood pressure support, antioxidant protection, liver health, and a broad spectrum of micronutrients. Adding spinach to the mix significantly amplifies the nitrate content and adds folate, iron, and carotenoids for skin and immune health.

Q: Can I drink beet and carrot juice every day?

Yes, in reasonable amounts. Because of the naturally occurring sugars in carrots and beets, most people do well with 8–16 ounces per day. If you're managing blood sugar carefully, keep an eye on portions. The spinach helps balance the glycemic impact slightly, and consuming the juice alongside other foods slows sugar absorption.

Q: Does cooking beets destroy the nitric oxide benefit?

Here's an important nuance: nitrates themselves are heat-stable, so cooking doesn't destroy them. What matters is the enzymatic conversion that happens in your saliva and gut. Raw beet juice preserves the full nitrate content, and your body's bacteria and saliva enzymes do the rest of the work to convert those nitrates into nitric oxide. Cooking beets doesn't eliminate the benefit, but raw juice gives you the most direct route.

Q: Is carrot beet spinach juice good for the skin?

Yes. The combination of beta-carotene from carrots, betalains from beets, lutein from spinach, and improved circulation from the nitric oxide boost makes this one of the best juice combinations for skin health from the inside out.

The Bottom Line

This juice has been popular on our site for years, and the science explains why. Carrot, beet, and spinach juice works on multiple systems simultaneously: cardiovascular health through nitric oxide, immune function through vitamins C and B6, skin health through vitamin A and carotenoids, and eye health through lutein and zeaxanthin.

I've been recommending vegetable juicing as a daily practice for a long time, and this combination remains one of my favorites. It's inexpensive, easy to prepare, and genuinely hard to beat for the range of benefits it delivers in a single glass. I personally like to squeeze a little lemon into it, too, to give it a citrus zing. And the ginger is a nice bonus, too.

If you're just getting started with juicing, this is the recipe I'd start with. And if you want the benefits without the prep time, take a look at BeetMax as a concentrated daily option.
