Health benefits Of Cranberry Juice


Cranberry juice comes from a small berry, also known by its English name: “cranberry”.

Renowned around the world for its deliciously sweet taste, this fruit is also a treasure trove of natural antioxidants.

Here is what you need to know about the health benefits of cranberry juice, a drink with unsuspected properties.

Cranberry juice: origin and nutrition facts

Cranberry berry comes from a plant that goes by many names: cranberry, North American lingonberry, lingonberry, stock, etc.

This small berry is very common and its use in industry is widespread. The richness of its composition is no stranger to it.

Cranberries, rich in vitamin C and various flavonoids, are one of the most antioxidant fruits in the world.


It is very difficult to find equivalents among other fruits. Likewise, the cranberry shines with the diversity of its natural antioxidants. But what exactly is it made of?

The cranberry whose juice is consumed contains vitamin C, citric acid as well as various phenolic acids.

You can also find organic acids, simple carbohydrates (fructose, D-mannose, glucose, sucrose) and polyols.

And that’s not all, since there are many other components to complete this list.

This is the case with proanthocyanidins, resveratrol, anthocyanosides, quinic acid and hydroxycinnamic acid.

Of course, this list ends with various natural flavonoids and antioxidants that the cranberry berry brings together.

And to understand its health benefits, you have to take an interest in its major active ingredients!

Antioxidants, active ingredients in cranberries
Vitamin C is naturally antioxidant, and it is present in large amounts in cranberries (and in its juice, by association).


To it are added flavonoids, which are antioxidant molecules present in most plants.

However, there are several, which are more or less concentrated depending on the fruit or the plant in question.

Here, the cranberry contains three main flavonoids, which are active ingredients present in very large quantities.

These are the natural antioxidants that help block the harmful effects of free radicals on the body.

Cranberry juice owes its red colour to anthocyanins (a flavonoid), which turns out to be a natural pigment. Resveratrol is a polyphenol belonging to the stilbenes. These are powerful antioxidants.

Thus, we quickly understand that the unusual composition of the fruit gives it its health properties.

The health benefits of cranberry juice are directly linked to the presence of several powerful natural antioxidants in its composition.

Health benefits of cranberry juice

Here are the details of the health benefits of cranberry juice: urinary tract infections, cardiovascular prevention, anti-cancer properties… They are very varied and concern different body systems.


1. Benefits of cranberry juice for cystitis

The properties of cranberry juice are known around the world, particularly in the prevention and treatment of urinary tract infections (or cystitis).

Cranberries (juice, infusion, dried fruit, food supplements, etc.) help prevent infection of various organs of the urinary system, especially in women. These organs are the urethra, the bladder or even the kidneys!

Cranberry juice contains a very special flavonoid: proanthocyanidin type A. This molecule prevents the bacteria that cause most urinary tract infections (Escherichia coli.) From adhering to the walls of the bladder. And therefore, to cause infection.

Due to its powerful antioxidant properties, cranberry juice facilitates the elimination of bacteria by stimulating urination and limiting possible anchor points for bacteria.

People who suffer or want to prevent the risk of UTI can include cranberries in their diet, in all its forms. It can be a very effective preventive solution in the context of recurrent cystitis.

Finally, cranberry is also a powerful antibacterial which acts on various other bacteria such as Vaccinium oxycoccos, Vaccinium myrtillus and Vaccinium Vitis-idæa. Its juice can be consumed to prevent infections that usually affect the urethra, kidneys or bladder.

2. Cranberry juice for cardiovascular health

Cranberry juice has been the subject of numerous studies, many of which are concerned with the beneficial effects of its flavonoids.

The latter is particularly useful in the prevention of cardiovascular diseases.


The natural antioxidants present in cranberries help to eliminate free radicals present in too many in the body. And they block the harmful effects on health.

Indeed, free radicals promote the development of cardiovascular diseases.

Cranberry juice, therefore, helps prevent the risk of atherosclerosis, which leads to other health problems and diseases.

Also, the active ingredients (antioxidants) in cranberry juice inhibit the oxidation of bad cholesterol and the aggregation of blood platelets.

Regular consumption of this drink helps reduce blood pressure and is effective against high blood pressure.

Finally, the health benefits of cranberry juice also extend to the heart muscle, since it is beneficial for the functioning of the heart!


3. Benefits of cranberry juice for stomach

Cranberry juice, therefore, acts on the urinary system. But it also preserves our intestinal system!

Studies on the berry show that its juice helps prevent and fight Helicobacter pylori infections, which affect the stomach.


This bacteria generally causes various gastric problems as well as chronic gastritis.

Consuming cranberry juice in addition to treatment adapted to these intestinal problems offers real support.

This drink helps eliminate bacteria from the intestinal system quickly and effectively.

Likewise, cranberry juice here can be combined with marjoram to offer superior relief to people who suffer from an intestinal infection, or to prevent it.

4. Fill up on nutrients, including vitamin C

Cranberries contain many nutrients, including a high concentration of vitamin C (or ascorbic acid).

It is also one of the best sources, alongside sea buckthorn berry, Camu Camu or acerola, in particular.

In the past, sailors consumed cranberry juice to prevent scurvy, a disease associated with a lack of vitamin C. Cranberry juice is an excellent source of vitamin C and essential nutrients.

We explained it at the beginning of the article: cranberries contain very powerful natural antioxidants (flavonoids).


Precisely, vitamin C is also the most antioxidant vitamin there is. Its effects are therefore added to those of the antioxidants naturally present in the berry.

To preserve these nutrients, choose fruits from organic farming, grown in season and the most natural conditions possible.

Likewise, the cold extraction of its juice guarantees the preservation of its many nutrients, including vitamin C and other antioxidants from the berry.

5. Cranberry juice for brain health

The cranberry berry, because of its antioxidant properties, is of considerable interest in terms of cell protection.

As such, it also acts on the preservation of neurons.

Cranberry juice helps to slow down and sometimes even reverse the phenomenon of loss of communication that can appear between neurons and different brain cells.

By consuming this fruit juice, it is possible to prevent age-related neuronal impairments and all those that affect cognition and motor mechanisms in our brain system.

Finally, the consumption of berries (blueberries, cranberries), fruits and vegetables helps to preserve memory and prevent the onset of Alzheimer’s disease.


These foods can also considerably slow down the development of the disease for people who have it.

6. Benefits of cranberry juice for cancer

Due to its content of active ingredients (very powerful natural antioxidants), cranberry juice is a passion for science.

Necessarily, researchers attempted to identify the potential benefits of cranberry juice in the prevention and treatment of various cancers.

Epidemiological studies carried out to date show that a diet rich in fruits and vegetables helps prevent the risk of cancer.

We now know that cranberry juice also helps prevent the risk of developing cancer. Its active ingredients block the proliferation and development of cancer cells.

Here, the small berry is particularly effective against breast, lung, colon and prostate cancers.

Cranberry juice contains ursolic acid. It is a molecule belonging to the triterpenes family, with considerable anti-cancer potential.

This is likely to slow down or block the proliferation of cancer cells of different types, especially in the face of liver or breast cancer.


The other health benefits of cranberry juice
The fruits and vegetables that we eat contain sugar (fructose), which is naturally present in their composition. As we know today, the fructose of fruits (like that of cranberries) has beneficial effects.

And in particular on dental health. Cranberry juice can therefore help prevent the onset of dental plaque, tooth decay or periodontal disease.

However, one should not consume just any juice. Many commercially contain added sugars, which are harmful to dental health.

It is, therefore, necessary to choose a natural, organic, cold-extracted cranberry juice without added sugar.

Or, you can make it yourself from fresh berries and a juice extractor! If you find it tastes too sour, consider healthy alternatives to refined sugar to sweeten your drink.

Side effects of cranberry juice

Drinking cranberry juice is feasible safe for most adults.

Drinking too much cranberry juice might cause some side effects such as mild stomach upset and diarrhea in some people.


Consuming cranberry juice is great in preventing many diseases. Some of them may be heavier than others.


From simple UTI to cancer, the panel of illnesses that cranberry juice helps prevent and cure is very wide. With antioxidants as major active ingredients, this fruit juice is a great ally.

He supports us against every day ills and the most serious pathologies. It would be a shame to deprive yourself of the health benefits of cranberry juice. Especially when we know that they are so numerous and diverse!
