Cranberry Juice- Heart, Blood Pressure

Share Button

Researchers note that cranberry juice is rich in antioxidants — naturally occurring molecules in fruit, tea, wine and other foods — which have been associated with lower blood pressure in other studies…”

I am a long-term survivor of multiple myeloma. I underwent lots of chemotherapy, radiation and an autologous stem cell transplant between ’94-’97.

Beside the fact that the chemo did little to manage my cancer, I developed a late stage side effect called chemotherapy-induced cardiomyopathy (CIC).

Over the years I’ve developed a heart healthy lifestyle including nutrition, supplementation and lifestyle therapies. As odd as it may sound, cranberry juice is one of those heart-healthy therapies.

Not just any cranberry juice. You’ve got to drink cranberry juice without sugar in it. And without sugar, the juice will taste sour. I mean really sour. My solution? Mix the juice into other fruit juices that you normally drink.

By doing this you will:

  • add antioxidants to every drink you add it to
  • you reduce the calories because of the added cranberry juice
  • you add flavor (sour flavor but flavor) to every juice you add it to
  • most importantly, you are adding a heart-healthy, blood pressure lowering component-

I’m not saying that by doing this you can forget about whatever heart therapies you take. I’m saying that by including evidence-based, non-toxic heart healthy therapies such as

  • cranberry juice as well as other heart-healthy foods
  • supplementation such as quercetin, curcumin, resveratrol, etc. 
  • frequent, moderate exercise, sauna, etc.

you may be able to lower the dose of toxic heart meds/blood pressure meds. you are taking.

When I developed atrial fibrillation (A Fib) in late 2010, my cardiologist confirmed a diagnosis of CIC and promptly put me on metoprolol. I got very little sleep that first night on metoprolol and decided to stop that medication ASAP. I am not a cardiologist. Be sure to check with a medical professional.

I am not advocating a specific brand of cranberry juice. I am simply saying that UNSWEETENED cranberry juice is good for your heart, and can lower blood pressure.

I have been able to stabilize my chemo-induced cardiomyopathy with heart healthy nutrition and supplementation-


I am saying that I have been managing my heart health ( CIC, blood pressure, A Fib, etc.) since late 2010 with a combination of non-toxic therapies. Cranberry juice being one of them.

If you have any questions about non-toxic therapies to manage CIC, A Fib, blood pressure, etc. send me an email. I will reply to you ASAP.

Thank you,

Cranberry Juice Fights Heart Disease

“Researchers have long suspected that antioxidant-rich cranberry juice may help lower risk of heart disease. However, this is the first study looking at the effects among people drinking the juice.

Besides heart disease benefits, previous studies have shown that cranberries can help prevent urinary tract infections and may reduce the risk of gum disease, stomach ulcers, and cancer…”

Low calorie cranberry juice lowers blood pressure in healthy adults, study finds

“In a study that measured the effects of drinking low-calorie cranberry juice, participants drank either low-calorie juice or a placebo drink every day for eight weeks as part of a controlled diet.

Blood pressure was measured at the beginning, mid-point and end of the study. After eight weeks, blood pressure values had significantly dropped from an average of 121/73 mmHg to 118/70 mmHg for those drinking the low-calorie cranberry juice. The placebo group showed no change.

Cranberries 101: Nutrition, Benefits, Uses, Side Effects, and More

“Cranberry juice made from concentrate offers about 70 calories per 8 ounces, plus 18 g of carbs and 26 percent DV of vitamin C, but no fiber, per the USDA. (6)

There are many other cranberry products, such as canned cranberry sauce and dried cranberries. The nutritional profile, including flavonoid content, changes depending on the product and its preparation method. Flavonoids are natural substances with antioxidant and anti-inflammatory properties, according to a review published online in December 2016 in the Journal of Nutritional Science. (7) Another study analyzed flavonoid content differences in fresh cranberries, freeze-dried berries, cranberry juices, cranberry sauces, and dried cranberries. The researchers found that the less processed the products were (as in homemade cranberry sauce versus store-bought), the higher the flavonoid levels. (8)

What are cranberries good for?
Cranberries and cranberry juice are rich in antioxidants and are excellent sources of vitamin C. They’ve been linked to preventing UTIs among people with recurring issues, possibly lessening the impact of cancerous cells, and boosting heart health.
Can I drink cranberry juice?
Yes, choose a variety labeled “100 percent cranberry juice” with no sugar added. Many varieties have sugar and flavor added, which take away from the healthfulness. Too much juice can lead to stomach issues, so speak to your doctor if you notice any adverse effects.

Health Benefits of Cranberries

Cranberries have been used in folk remedies to treat disorders involving the bladder, stomach, and liver, as well as diabetes and wounds. (2)

Here are some potential cranberry benefits:

Preventing Urinary Tract Infections (UTIs)

Cranberry juice is often said to help with UTIs, a common bacterial infection. Research shows that there’s some truth here — they do seem to protect against recurring UTIs. A meta-analysis published in December 2017 in The Journal of Nutrition involving participants who had a history of UTIs found that cranberry reduced the risk of a recurring UTI by 26 percent. Nonetheless, more studies are needed to understand the reason for this benefit. (9)

“It is likely that compounds in cranberries help keep bacteria from adhering to surfaces in the bladder,” says Kelly Jones, RD, CSSD, a sports dietitian based in Philadelphia. Cranberry juice works better as a preventive measure than as a treatment, according to the University of Rochester Medical Center. (10) The science is mixed, though. Earlier research found that drinking cranberry juice daily didn’t significantly reduce UTI risk. (11)

Keeping Certain Cancers at Bay

A review published in September 2016 in Antioxidants found that cranberries may have a positive effect on 17 types of cancer, potentially due to their ability to help slow the growth of cancerous cells and clear them from the body. The authors said more research is needed to confirm a causal relationship between cranberries and cancer prevention, but the results so far seem promising. (12)

Improving Heart Health

A limited but growing body of research has shown that consuming cranberries may positively affect cardiometabolic health, including blood pressure and serum lipid profiles, according to a study published in July 2016 in Advances in Nutrition. (13) Cranberries may also positively affect cholesterol levels and have been shown to reduce cardiometabolic risk factors, according to a review published in November 2020 in the Journal of the Science of Food and Agriculture. (14)

Warding Off Kidney Stones

Some people have linked cranberries and kidney stones. The idea stems from the fact that cranberries contain the molecule oxalate, which can sometimes stick together and form a kidney stone, according to the National Kidney Foundation. (15) In reality, though, cranberries don’t seem to be to blame. The foundation doesn’t list cranberries as foods that are especially high in oxalate, and what’s more, a study published in American Family Physician noted that cranberry juice can make urine more acidic, which may help prevent stones in the first place. (16)

Additional Benefits of Cranberries

Cranberries and cranberry juice have also been linked to other health benefits, including increased sex drive, constipation relief, and treatment for yeast infections and upper respiratory infections, but the research surrounding each of these is murky. (10)
