Certain supplements can raise blood pressure either by directly affecting the cardiovascular system or by interfering with blood pressure medications.
This article will examine whether vitamins and supplements raise blood pressure, and supplements to avoid if you have high blood pressure or are on medications to lower blood pressure or thin the blood.
Do Vitamins Raise Blood Pressure?
Dietary supplements include vitamins, minerals, and herbs that add to or “supplement” the nutrients you get from food. They are readily available in stores and online, and often are marketed as helping to improve or prevent certain health conditions. However, unlike prescription and over-the-countermedications, supplements do not have to be approved by the FDA to ensure they are effective and safe, or undergo clinical research to back up their claims.Some vitamins and supplements, such as coenzyme Q10 (ubiquinone) and melatonin, have been found to have antihypertensive effects, meaning they can help lower blood pressure. However certain supplements have been found to raise blood pressure or interact with blood pressure, blood-thinning, and other medications. It’s important to talk to a healthcare provider before taking anyvitamin or supplement.

Arnica
Arnica comes from a perennial flower and is most often used in topical creams and ointments to assist in the healing of bruises, sprains, swelling, and inflammation. Arnica is considered safe when used on the skin but should not be taken by mouth in pill or other forms. When taken internally arnica can cause heart issues, dizziness, and other medical problems, and can be fatal in large doses,
Asian (Panax) Ginseng
Asian ginseng, also known as panax ginseng, has been promoted for a variety of uses including to increase wellbeing, reduce stress, and improve concentration and memory. Ginseng has been found to elevate blood pressure, although this typically occurs in those with low blood pressure. In those with low blood pressure, taking ginseng can restore blood pressure to normal, but in those with high blood pressure, it may be dangerous.
It’s not certain whether ginseng interacts with certain medications including blood thinners, and calcium channel blockers and other medications for high blood pressure. Anyone taking these medications should consult with a healthcare provider before using ginseng.
Bitter Orange
Bitter orange is a supplement that comes from extract of the fruit or peel of a bitter orange. It’s often used in weight-loss supplements and sports performance products. While there have been cases reported of heart attack, angina, and stroke after consuming products that contained bitter orange, it’s not known for certain if bitter orange or other ingredients played a role. Studies on whether bitter orange increases blood pressure or heart rate have produced conflicting results.
Guarana
Guarana contains caffeine and is an herb commonly used in energy drinks. Many energy drinks contain high amounts of caffeine, and adding guarana increases caffeine amounts. Excessive caffeine can cause increases in blood pressure and heart rate, and heart rhythm disturbances.
Licorice Root
Licorice root is a supplement most commonly used for digestive issues such as heartburn, along with coughs, and viral and bacterial infections. Licorice root can have serious side effects including increasing blood pressure, especially when it’s consumed in large amounts or over long periodsof time.
Licorice also decreases potassium, which plays a role in blood pressure. Licorice should not be taken by anyone with high blood pressure or heart disease.
St. John’s Wort
St. John’s wort is an herb that’s used for a variety of conditions including depression, menopausal symptoms, attention-deficit hyperactivity disorder (ADHD), and obsessive-compulsive disorder (OCD). St. John’s wort can cause serious interactions with many common drugs including blood thinners.
Vitamin E
Vitamin E is an antioxidant that protects the body’s cells from damage. High doses of vitamin E might increase the risk of bleeding after an injury or bleeding in the brain because it reduces the body’s ability to form blood clots. Vitamin E can also increase bleeding risk for those onblood-thinning medications. It is recommended that adults take no more than 1,000 mg per day of natural or synthetic vitamin E supplements.
Vitamin K
Vitamin K helps the blood clot and keeps bones healthy. Vitamin K can interfere with how blood-thinning medications work, which can increase the risk of blood clots, heart attacks, or strokes. Those taking blood thinners needs to keep their intake of vitamin K at consistent levels. Any sudden changes in vitamin K levels can interfere with the medications’ effectiveness.
Yohimbe
Yohimbe comes from the bark of African evergreen trees. It’s most commonly touted for helping erectile dysfunction and increasing sexual arousal. Yohimbe has been associated with serious side effects including high blood pressure, rapid heartbeat, and heart attacks. Its use has been restricted in many countries.
Summary
Unlike prescription or over-the-counter medications, the FDA does not oversee the sale of vitamins or other supplements. Some common vitamins and supplements can raise blood pressure or alter how blood pressure or other medications work. You should always seek the advice of a healthcare provider when considering taking any supplement, especially if you are taking medication to control blood pressure or blood-thinning medication.
A Word From Verywell
Don’t just believe the hype. Always ask a healthcare professional if a supplement will benefit you, or comes with side effects or drug interactions that could potentially be harmful.
