The blueberries are a good source of vitamin C, vitamin K, vitamin A, manganese and potassium.

Blueberry juice is rich in vitamin C, an essential nutrient for overall health.

Vitamin C helps in the production and repair of body tissues, and it also helps produce collagen, a protein essential for healthy skin, cartilage, ligaments, tendons, and blood vessels.

This vitamin also helps maintain healthy bones and teeth and helps in healing wounds.

Blueberry juice and Antioxidants

Blueberries and pure blueberry juice are very antioxidant foods, due to their high levels of polyphenols – specifically, anthocyanins, the phytochemical that gives blueberries their colour.

The high levels of vitamins A, C, and E also contribute to blueberry juice’s reputation as a super antioxidant.
Antioxidants help protect your cells from the effects of free radicals.


These molecules are produced when your body breaks down certain foods, or by exposure to environmental toxins, such as radiation or tobacco smoke.

Free radicals can damage cells and can contribute to the risk of heart disease and cancer.

Health benefits of blueberry juice

Consumed intelligently and regularly, blueberry juice can provide exceptional health benefits.

It works beneficial and can markedly improve digestive health, urinary tract health, heart health, brain health, reduce the risk of heart disease, the ageing process, lower blood pressure and manage diabetes, relieve muscle damage after exercise, support weight loss, eye health and improve vision.

All the virtues and properties mentioned below are scientifically proven; they are the result of numerous studies carried out around the world.

1. Benefits of blueberry juice for digestion

The blueberry juice can be of great help when it comes to improving digestive health.

Blueberries are a rich source of tannins, able to reduce inflammation in the digestive tract, and also to counteract the phenomena of constipation and diarrhoea.

Tannins, true antagonists of Helicobacter pylori, also improve the digestive system and its functions, actively contributing to the reduction of peptic ulcers. H. pylori are often identified as a primary cause of peptic ulcers in adults.


2. Urinary health preserved

The people who drank blueberry juice often display better urinary health.

This finding is likely due to antioxidants called proanthocyanins that block certain types of bacteria, including E. coli, from infecting the urinary system.

3. Benefits of blueberry juice for urinary tract infections

Besides, blueberry juice is a rich source of vitamin C, which can provide relief for women and men suffering from urinary tract infections.

A few 100% pure centilitres contain a good portion of the recommended daily allowance of vitamin C.

To prevent and aid in the treatment of urinary tract infections, cranberry juice is often used; in the same way, the juice of blueberries can help improve, and even act in the treatment of cystitis and other infections of the urinary tract.

Bilberries and cranberries are closely related and share the same active ingredients that help treat UTI.

To do this, it is advisable to drink 100% natural blueberry juice and not a fruit juice cocktail containing blueberry juice, prepared with sugar which can aggravate the situation.

4. Blueberry juice and brain health

In addition to slowing the decline in mental function often occurring alongside the effects of ageing, blueberries can prevent the onset of certain mental health disorders, including Alzheimer’s disease.


In this regard, scientists suggest that this improvement in cognition probably occurs due to the high flavonoid content of blueberries.

These flavonoids can be particularly effective in improving working memory and processing speed, and therefore cognitive functions.

Support Brain Health: Free radicals and oxidative stress can damage the brain; this is where blueberry juice can distil its benefits.

Indeed its antioxidants fiercely fight the latter, thus helping to improve brain health. Several recent studies performed on the elderly have found that consuming blueberries delays cognitive impairment.

5. Reduces the risk of heart disease

The blueberry juice can also be effective in preventing heart disease.

Anthocyanins – pigments found in blueberries and blueberry juice – consumed at least once a week, are effective in lowering blood pressure.
Low levels of blood pressure greatly reduce the risk of stroke and heart attack.

The reduction in blood pressure values, even relatively low, leads to a significant decrease in cardiovascular events.

Prevent Heart Disease: Blueberry juice works favourably against high blood pressure and therefore helps reduce the risk of heart disease.


6. Benefits of blueberry juice for weight loss

The blueberries and blueberry juice can help with weight loss.

Recent studies demonstrate the ability of the active ingredients in blueberries to reduce fat mass in rats regardless of their diet.

Researchers believe that these little berries have an impact on the way our body stores and break down sugar.

Although the study was conducted in rats and more research in human subjects is needed, previous studies suggest similar results.

7. Blueberry juice against the ageing process

Thanks to its high concentration of antioxidants, blueberry juice can help fight damage caused by free radicals which accelerate the ageing process.

In one study, participants consumed blueberry juice combined with apple juice for four weeks.

Researchers found that DNA damage and oxidative stress – which promotes ageing and increases cancer risk – was reduced by 20%.

8. Antioxidant reservoir

As mentioned above, blueberries and blueberry juice are rich in antioxidants, which fight free radical damage.


Blueberries offer a greater amount of antioxidants, compared to other fruits.
Aside from fighting free radicals, antioxidants are also linked to improving overall health.

9 Benefits of blueberry juice for blood pressure

Recent studies prove that consuming blueberries and blueberry juice is associated with reduced blood pressure.

After eight weeks of consuming 50 grams of blueberries per day, patients with high-risk heart disease experienced a 4-6% drop in blood pressure.

10. Benefits of blueberry juice for diabetes

The blueberries are low in sugar, making it a healthy snack for diabetics, which will not increase sugar levels in the blood. The properties of blueberries may also benefit insulin control and sensitivity.

11. Relieve muscle damage after strenuous exercise

After an intense workout, the muscles may be fatigued and sore, but this muscle fatigue can be improved with the consumption of blueberry juice.

Blueberries can help reduce inflammation and oxidative stress in muscles, thereby speeding up tissue repair.

12. Support eye health and improve vision

The antioxidants in blueberries can help eye health by preventing free radical damage to the eyes and resulting vision problems.

Hypertension contributes to impaired vision. Blueberries also help regulate blood pressure and therefore protect eye health.


Side effects of blueberry juice

Because Rich in fibre, potassium and vitamins A and K, blueberries alone represent a real nutritional reservoir.

Unfortunately, in some cases, they can have side effects, such as gastrointestinal upset, low blood sugar and increased risk of bleeding if you are already taking medicines to thin the blood, or if you have haemophilia.

If you are in good health, eating blueberries or drinking their juice as part of a balanced diet is unlikely to cause side effects.

However, if you have an underlying health condition, check with your doctor before adding them to your diet.

Especially in cases of sensitivity to salicylate, anticoagulant treatments, severe diabetes and frequent hypoglycemia.
