Supplements and Vitamins to Be Careful With If You Have High Blood Pressure
If you have high blood pressure, it’s important to consider how supplements and herbal products may affect your blood pressure or interact with medications.
Although many products are marketed as natural, natural does not always mean risk-free. Some supplements may affect heart rate, blood pressure, electrolyte levels, or the way certain medicines work.
Before starting a new supplement, especially if you take medication for high blood pressure, speak with a qualified healthcare professional.
Supplements That May Affect Blood Pressure
1. Licorice Root
Licorice root can contain glycyrrhizin, a compound that may cause the body to retain sodium and lose potassium when consumed in significant amounts.
These effects can contribute to increased blood pressure in some people.
If you have hypertension, avoid using concentrated licorice supplements without discussing them with your healthcare professional.
2. Asian Ginseng
Asian ginseng is commonly used in herbal products marketed for energy and alertness.
Its effects can vary between individuals, and it may interact with certain medications. People with high blood pressure should discuss ginseng supplementation with their healthcare provider before using it regularly.
3. Guarana
Guarana naturally contains caffeine and is commonly included in energy and weight-management products.
Because caffeine can temporarily increase blood pressure and heart rate in some people, products containing concentrated guarana may not be appropriate for everyone with hypertension.
Check the total caffeine content of supplements and energy products before using them.
4. Bitter Orange
Bitter orange is found in some weight-loss and sports-performance supplements.
It contains compounds that may affect heart rate and blood pressure. Evidence regarding its effects is not completely consistent, so people with hypertension should be cautious and consult a healthcare professional before taking concentrated bitter-orange products.
5. St. John’s Wort
St. John’s wort is an herbal product commonly used for mood-related concerns.
One of the biggest concerns is its potential to interact with medications. It can affect enzymes and transport systems involved in how the body processes many medicines.
This may reduce or alter the effects of certain prescription medications, including some cardiovascular medicines.
If you take blood-pressure medication or other prescriptions, speak with your healthcare provider before using St. John’s wort.
6. Yohimbe
Yohimbe is an herbal ingredient found in some supplements marketed for weight management, energy, or sexual health.
It can have cardiovascular effects, including increases in heart rate and blood pressure, and may cause other adverse effects.
People with high blood pressure should avoid using yohimbe unless specifically advised by a qualified healthcare professional.
7. Arnica
Arnica is commonly used in topical products for muscles and joints.
However, concentrated oral arnica can be unsafe and should not be taken without appropriate medical guidance. People with health conditions or those taking medication should discuss herbal products with a healthcare professional before using them.
What About Vitamin E?
Vitamin E is an essential nutrient, and getting it from foods is different from taking a high-dose supplement.
High-dose vitamin E supplements may increase bleeding risk, particularly when combined with certain medications.
If you take blood thinners or other medications, ask your healthcare professional whether vitamin E supplementation is appropriate for you.
What About Multivitamins?
A standard multivitamin may be appropriate for some people, but taking more vitamins is not necessarily better.
Whether you need a multivitamin depends on your diet, age, health status, medications, and nutritional needs.
A balanced diet containing vegetables, fruits, whole grains, legumes, nuts, seeds, and other nutrient-rich foods is generally an important foundation for good nutrition.
Why You Should Check With Your Healthcare Provider
Supplements can interact with prescription and over-the-counter medications. Some may affect blood pressure, heart rate, blood clotting, or electrolyte levels.
Before starting a new vitamin, mineral, herb, or other supplement, tell your healthcare professional about everything you currently take.
This is particularly important if you have high blood pressure or another cardiovascular condition.
The Bottom Line
Having high blood pressure doesn’t automatically mean you must avoid every vitamin or supplement. However, certain herbal products and concentrated supplements can affect blood pressure or interact with medications.
Be especially cautious with products containing ingredients such as licorice root, guarana, bitter orange, yohimbe, and St. John’s wort.
When in doubt, check with a qualified healthcare professional before starting a new supplement.
