Supplements that can lower, or raise blood pressure -- blood pressure cuff and bottle of pills
There are many supplements, including fish oil, curcumin, certain probiotics, cinnamon and others, which may lower blood pressure. However, if you already take medication to lower blood pressure, always consult your physician before using these supplements, as they may lower your blood pressure too much, or interfere in some other way with your current medication. Be aware that a number of supplements can increase blood pressure. Sign in to see the full answer >>

I have been taking L-Carnitine 1000 -1500 mg daily, which have lowered systolic and diastolic readings by 15 -20 points. I have also added Berberine 1500 mg daily.

Im 85 male .. have high blood pressure for past 24 years that I know. maybe more. Doctors want to put me on prescription med. I said no. Tried it didnt like side effects. Ive tried a lot of things ie. olive oil, L arginine, flax seed, liquid coQ10, liquid Turmeric, cinnamon, curcumin, reservatrol, CBD, green tea, etc. Nothing works. I check it at home and doctors office. Any suggestions??

I think that it helps to try different supplements/foods (of the ones that CL has mentioned above as possibly helping lower BP), to find what's best for you personally. My husband tried using olive leaf extract, hibiscus tea and cinnamon at one time or another over the years, and none of those helped. What seems to have worked for him is olive oil. I make sure to give him at least 2 tablespoons of it with lunch and liberally use it in my cooking and to drizzle over certain foods; even cut fruit and yogurt tastes good with some olive oil in it. His blood pressure is now in the normal low end of the range.

My husband has been taking Hawthorne in place of Lisinopril for over 3 years with excellent results. I got the approval of his doctor before we made this change.   August 23, 2019
Hi Margaret - Thank you for sharing this. The Encyclopedia article about hawthorn includes the evidence for and against its use for lowering blood pressure

I have been taking a small amount of CBD for anxiety (it works) and to my surprise it normalise my blood pressure from 145am/90pm to 127am/105pm. Amazing side effect,
no drug can do that.

Zion18668   November 24, 2019
Thank you for your post. I am in a similar situation and I'm wondering what CBD brand you're taking that helped you with your blood pressure?

Thank you

micheline19453   April 12, 2020
Sorry, didn't see your post earlier. I buy from recommended by a doctor and inexpensive.

Hi Micheline:
I have not seen am & pm in blood pressure readings, but maybe that is my fault, not yours. Usually I see something like 120/80 mm Hg, with 120 the systolic reading & 80 the diastolic.

I also have blood pressure problems & I take CBD. I am curious that one number went down from 145 to 127, while the other number went up from 90 to 105.

I wish you continued success with CBD & your heart & your health!!


Patricia19115   February 27, 2020
I believe the am referred to a systolic blood pressure reading taken in the morning, and pm the value for systolic pressure taken in the evening. No values were given for the diastolic pressure readings.

Patty19068   February 5, 2020
which brand of cbd oil worked for you ? there are so many.....

Patricia17105   August 26, 2018
Having tried just about all the above suggestions - the ones I can pronounce and easily spell - over the past few decades, I was very happy to finally find what worked for me - big time. Vitamin C, when taken in large amounts dropped my blood pressure from 132/80 to 110/70 virtually overnight. Using 2500-5000 mg per day mixed into my drinking water kept my bp down, forgetting to mix and all it took was a couple of days for it to quickly return to 130/80. Note the decrease in the spread of 10 points, also a significant/healthy change.

Warning: Taking high amounts of C didn't change my number of daily BMs but it certainly changed the consistency, ie, bowel intolerance - get to know your number before getting too far from a toilet.

Hi Patricia - Thank you for sharing your experience with this. However, please be aware that this is a very large dose of vitamin C, which can have negative effects (see the "Concerns and Cautions" section of the Vitamin C Review: In clinical studies showing vitamin C lowered blood pressure, lower doses were used (see the "What It Does" section of the Vitamin C Review:

Patricia17658   March 20, 2019
Another 67 year old, active male, would like to ditto your comments. For the first time in decades my Bp is under 120/80, although it took weeks. I should also add that I started taking Magnesium supplements around the same time which erased what I thought was an irregular heart-beat, but now suspect heart spasms were causing the symptoms. Potassium supplements will soon be added to complete our daily electrolyte restoration. Do Docs even check electrolytes in senior patients - all that tea and coffee we consumed we replaced with water but obviously we were stripping away our electrolytes. With all the sugar in natural juices and being low calorie consumers over-all, we simply cannot keep enough electrolytes in our systems without supplementation.

My personal experience with olive leaf is that it lowers blood pressure as stated in the article. Normally when I go in for a check-up, it's right around 120/80. Last summer at my regular check-up I had been taking olive leaf for a couple of weeks, and my blood pressure registered 101/58.

Like other supplements, the actual level olive leaf extract in the olive leaf capsule can be different from the percentage stated on the label. Good brands I have used are Olympian Labs and Natural Factors. Consumer Labs reviews would show others as well. Before using be aware olive leaf usually cleans out your digestive system the first couple of days of use.

Rutin works. Lowered my BP by 7-10 points.

HTN is poorly understood. HTN is just a symptom and there are many causes. Meaning specific supplements only work on specific causes. The real question is how do I identify what is causing my HTN so I can correct it?

eve16232   November 22, 2017
why not eat a whole food plant based diet, with no flesh. the body makes its own cholesterol. it doesn't need any from animals. that way a body would get all those vitamins and minerals and phytochemicals without taking any pills. what do you think?

Trace16223   November 20, 2017
Good morning, I would say you're missing one of the most important supplements to take for high blood pressure. There are at least a dozen studies on Co Q10 lowering blood pressure. It's very safe, very cheap nowadays, and very effective.   November 22, 2017
Hi Trace - We've now added information about CoQ10 in the answer above.

Richard A16218   November 19, 2017
I read on WebMD

"For high blood pressure: 120-200 mg per day divided into 2 doses."

I would be very interested in your thoughts on this since I am taking 100 mg twice a day to help with my high blood pressure and offset any adverse effects of the low dose Lipitor (5 mg/day) I am also taking. Thank you. I consider Consumer Lab a reliable source of information on the web.   November 30, 2017
Thank you for your kind words, Richard. We've added information about CoQ10 to the answer above.

My husband was taking Lisinopril for BP issues, and we were uncomfortable with the potential side effects. After checking it with his doctor (GP) I discontinued it and put him on Hawthorne Extract - Total of 2500 mg. divided into the 3 meals. It took a few weeks to stabilize, but for over a year and half now his BP reading is usually around 128/62.

Hortensia16226   November 22, 2017
Did he continue taking his blood pressure medication while taking the Hawthorn? I had read online from a pharmacist not to take at the same time. Just asking...

Margaret18222   August 21, 2019
No, it was a complete replacement.

joe16233   November 23, 2017
What do you think was causing your husbands HTN ?
Was it reversed?
Why is hawthorne extract effective at lowering blood pressure?
Is it safer than ACE inhibitors?
Are there any risks?   November 23, 2017
Hi Joe - Please see the Encyclopedia article about hawthorn:

With liquid Hawthorn, how many drops does 2,500 mg. come out to? My Nature's Answer liquid Hawthorn I've been taking is 2,000 mgs & I've been taking 24 drops 2-3 times a day.

mary16216   November 19, 2017
There are at least 6 studies showing co-enzyme Q 10 in doses of 300 and 350 mg/day lower synstolic and diastolic BP. I am surprised you didn't mention this important supplement for BP control. I am a registered and lic. ensed dietitian and nutritionist and use co Q 10 often with patients.   November 30, 2017
Hi Mary - Please see the information we've added about CoQ10 to the answer above.

Mary 16215   November 19, 2017
I have read that olive leaf supplement can lower blood pressure. Is there any research done on that? Thanks.   November 22, 2017
Hi Mary - Thank you for your question. We've added information about olive leaf extract to the answer above.

Geri16214   November 19, 2017
How about hibiscus tea? I've read it can be helpful!   December 19, 2017
Hi Geri - Please see the Encyclopedia article about hibiscus ( for the clinical evidence for its use to lower blood pressure.

Heather17663   March 21, 2019
Readers can go to People's Pharmacy website, enter hibiscus tea in the search box, and several articles will come up regarding use of this tea for high BP, including how to prepare it (flower to water ratio). I began fixing it for my husband just as his BP was beginning to increase, and a daily serving of it has kept his BP within normal range.

What about the use of natural reserpine that is found in the supplement Carditone?
It seems to work well for many people and used to be a prescription drug.   June 13, 2016
Hi Fred - Thank you for your question. We've now answered it here:

Lina9764   June 1, 2016
I was wondering what amounts to take the supplements. You do not mention how much to take to achieve the goal of reducing blood pressure.   June 1, 2016
Hi Lina - The links for each supplement in the answer above provide information about dosage.

I did not find anything on celery seed. I heard that it has been very successful for lowering high blood pressure. Thank you.   March 4, 2016
Hi Ron - There is some preliminary evidence that celery seed extract may help to decrease elevated blood pressure; for example, it was found to lower blood pressure in rats with high blood pressure, but not in rats with normal blood pressure (

We are aware of only one study in people, which was authored, in part, by employees of the companies which sell the exact used in the study ( This study found that 150 mg of celery seed extract standardized to contain 85% 3-n-butyl phthalide (3nB) taken daily decreased systolic blood pressure an average of 8.2 mmHg and diastolic blood pressure an average of 8.5 mmHg after six weeks. However, this study did not include a placebo, and so the significance of this is not clear.
