Beetroot juice (also called beet juice) may have a very modest effect on lowering blood pressure. Most beetroot supplements, however, are unlikely to provide the benefit of the juice. See the full answer for details, including dosage >>

I too get 10points or more reduction on both sbp & dbp with one 8 oz cup of fresh juiced beet juice with carrot and celery, every few days. Same as what Dr Oz. show reported.

June 15, 2016

I traveled from elevation of 2000 to 5000 in mountains. My BP increased from
132/90 t0 144/91 after 4 days at higher elevations . I was concerned so researched
And found study on beet juice that found the nitric oxide in beet juice consumption led to systolic reduction in BP. The next day I took 1/2 of 25 mg. diuretic (Spirinolactone) and I ate the following for lunch (as experiment) to reduce BP; 1 avocado with 1/2 can sliced beets (no sodium added) and handful fresh spinach, topped with Balsamic vinegar. Took BP 5 hours later and BP went from previous 144/91 down to 121/85 (remarkable). Did same lunch next day and went down to 115/80, and day 3 in morning was down to 114/74 without taking diuretic, did not eat lunch yesterday and ate dinner out. This morning BP was 129/83. Will eat above lunch today to see if get same reduced BP tonight.

I think that was more due to acclamation than supplemental.

Be aware that drinking large amounts of beet juice may resultin beeturia, turning the urine red. While the condition is likely harmless, it can confused with passing blood in the urine.

Thank you Sanford. This is noted under "Cautions" in the answer above.

I have no opinion about beetroot. The article presents a balanced view. However, the following facts should be mentioned:

1. A 4mm reduction in systolic blood pressure is worthwhile, and similar to that achieved with some blood pressure medicines, reducing drinking, or reducing sodium.
2. Systolic BP is more important than diastolic.

Two cups daily of home-made beet juice made with fresh or steamed beets reduced my systolic blood pressure from 140-170 to 120-135 allowing me to wean myself of beta-blocker and nitrate prescriptions. However, after about two weeks, I developed itchy bumps on my skin. By reducing my beet juice intake to 1 cup daily the incidence of skin problems has decreased, and I am now taking along with it minimal doses of angiotensin receptor blocker (25 mg/day) and nitrate (5 mg/twice a day). By the way to enhance the taste and effectiveness of the juice, I also add berries, melon, celery,apple …whatever I have on hand.

Thank you Myra for your comments on the skin problems after taking the beet juice. I have been taking large doses of arginine (about 2,000 mg), to increase NO for mild hypertension, and within q week or so I also experienced red rashes and bumps on my thigh. This correlation, along with your post, will probably save me a trip to the dermatologist.

High arginine may be contraindicated for people prone to shingles (herpes). Check this out.
August 24, 2017

Hi Margie - There is some evidence from laboratory studies that arginine is required for the herpes virus to replicate ( although there do not appear to be published reports of arginine supplementation worsening symptoms in people with shingles. For more about this, see the Encyclopedia articles about arginine: and shingles article:

After taking 6 gr Arginine/6gr Citrulline for over 1 month, developed what I believe to be shingles. Upon ceasing the use of both supps for 5 days, the rash subsided, but had not completely cleared. I then took 2 gr Arginine to confirm the rash was reactive it, resulting in the rash flaring a bit, thankfully it was short lived. I am discontinuing supplementation for a few weeks, til it's completely receded. My blood pressure had been greatly reduced from the supplementation (150-160 down to 109-130), which I turned to when the ARB (50mg) I was taking made me feel ill with headaches, fatigue, depression and increased BP. I tried 3 different manufacturers of the ARB and have since filed complaints with the FDA to inform thiem of my experience. I like the idea of the spinach, avocado and beet salad, letting food be my medicine.

Thank you for sharing your experience. To our knowledge, skin rash is not commonly reported by people taking arginine. See the Cautions and Concerns section of our Arginine Supplements Review for information about what has been reported ( Also, keep in mind that you should always speak with your doctor before taking a supplement in place of a prescribed medication.

what about hibiscus tea for blood pressure?
August 2, 2017

Hi Eve - The evidence for hibiscus lowering blood pressure is quite preliminary, and better quality studies are needed. You can read more about this in the Encyclopedia article about Hibiscus:

Beet juice is also very high in carbs, around 25 g per cup.

Just an FYI on beetjuice, if you choose to lower BP on occasion with beetjuice that is fine, but please avoid drinking beetjuice on a daily basis. It is very high in oxalates and can cause kidney stones. Good health to all.
