5 Supplements That Raise Blood Pressure: Doctor Warns Hypertensives.

According to ТСН: Controlling arterial hypertension is an important step in preventing serious conditions such as heart attack or stroke. However, many people are unaware that even natural vitamins and herbal mixtures can complicate treatment or raise blood pressure. Pharmaceutical sciences doctor Kirstin Hill points out five supplements that should be approached with particular caution when dealing with high blood pressure.

1. High Doses of Vitamin D

Vitamin D is essential for bone health and the immune system, but its excess can be toxic. Consuming doses over 10,000 IU per day can lead to calcium buildup in the blood (hypercalcemia), which harms blood vessels and increases blood pressure. Additionally, large doses of vitamin D can reduce the effectiveness of diuretics, which are often prescribed to hypertensive patients.

2. Licorice Root

This plant is commonly found in teas, candies, and cough remedies, but it can be dangerous for the cardiovascular system. Glycyrrhizin in licorice causes the body to retain sodium and excrete potassium. This creates an electrolyte imbalance, causing sharp fluctuations in blood pressure. Combining licorice with diuretic medications can lead to critical potassium deficiency.

3. St. John's Wort

St. John's Wort is renowned as a natural antidepressant, but it poses another danger for people with hypertension. This plant affects liver enzymes responsible for breaking down medications. As a result, the effectiveness of blood pressure medications such as nifedipine or verapamil is significantly reduced. Patients may continue taking the drugs, but their action can be blocked by the supplement.

4. Arnica

Although arnica is beneficial for external use in treating bruises and swelling, oral consumption (in the form of tablets or drops) is strongly discouraged. Taking arnica by mouth can cause serious damage to heart muscle, nausea, diarrhea, and a sudden increase in blood pressure. Experts recommend using this plant only externally on unbroken skin.

5. Bitter Orange

This supplement is often used in weight loss and sports nutrition programs due to its synephrine content, which acts similarly to ephedrine, prohibited due to a high risk of heart attacks. Bitter orange activates the nervous system, increases heart rate, and constricts blood vessels, which raises risks for people with hypertension.

Every body reacts differently to biologically active supplements, depending on age, genetics, and health status. Before introducing new supplements into your diet, be sure to consult your doctor. Only a specialist can assess their compatibility with your medications and recommend a safe dosage.

In the context of modern life, it is important to remember the consequences that even natural supplements can cause. Awareness of potential risks will help make informed decisions regarding one's health. This is particularly relevant for individuals suffering from high blood pressure — they should be especially cautious in their choice of supplements and treatments.
