Herbs and Vitamins People With High Blood Pressure Should Avoid


Some herbs, vitamins, and minerals have substantial health benefits others like these below don’t. A few of the things to consider:

Vitamin D

Studies show that people with low vitamin D at times also struggle with blood pressure issues. This might be due to vitamin D being a key vitamin that modulates blood pressure indirectly.

A systematic review and meta-analysis discovered in studies totaling up to 25,000 people, that supplementation with vitamin D did not affect blood pressure. The main difference could be in older or obese people with low vitamin D levels. That is where a correlation with high blood pressure has been found.

Herbs and Vitamins People With High Blood Pressure Should Avoid


Arnica is an herb belonging to the sunflower family. It has traditionally been used for treating injuries and pain, but today, there are various arnica supplements available in diluted forms for ingestion.

Taking it in moderation is key, else you will develop high blood pressure, shortness of breath, vomiting, elevated heart rate, rashes, etc.


Guarana is one of the  foods that give you energy and that’s why it is integrated in energy drinks. The native Amazon plant contains caffeine as well as theobromine and theophylline (both are similar to caffeine).

Caffeine and substances that are similar to caffeine can increase the heart rate and, thus, increase blood pressure. According to research guarana and ephedra supplements, even when taken as prescribed, can increase blood pressure and heart rate.


Ephedra is an arid to semi-arid region herb known for its dangerous reactions which may include rare cases such as:

  • Strokes
  • Seizures
  • Heart attacks

Ephedra causes blood pressure elevation and causes a quick heartbeat, especially if you take caffeinated ephedra while with HBP. These herbal supplements are usually used for weight loss. When you take ephedra in doses of 150mg, it can cause a significant increase in both pressure and heart rate.

Staying away from caffeine and any type of fat-burning supplement is ideal for people that have high blood pressure. Smarter food and dietary choices can have a strong effect on regulating blood pressure.

  1. John’s Wort

St. John’s Wort is a well-known herb often used to treat depression. Additionally, the herb has been used topically to treat wounds.

  1. John’s Wort may be a helpful herb for some individuals, but St. John’s Wort has been linked to some severe side effects and potentially risky drug interactions. Notably, St. John’s Wort has been shown to raise blood pressure.


Sodium is found in many multivitamins. So while it is not technically one of the vitamins to avoid with high blood pressure, It is listed here because it is worthy of note. Sodium can be found in several food types and is responsible for nerve and muscle function.

Excess sodium is associated with elevated blood pressure levels. Lowering consumption can bring down blood pressure levels and improve vascular function.

The list of vitamins to stay away from if you have high blood pressure is short, but there’re several herbs and minerals that can be avoided. Natural supplements like beetroot supplement or red spinach supplement may be adopted safely for boosting nitric oxide in a way that is sustainable and healthy.
