Vitamin C may have a beneficial effect on blood pressure, but the research is inconclusive. Several studies have shown that people with higher levels of vitamin C in their bloodstream have lower blood pressure than those with lower levels.
However, a number of other studies have failed to find a significant link between vitamin C intake and blood pressure.
One reason for this inconsistency may be that vitamin C is just one of many nutrients and other factors that play a role in blood pressure. Also, our bodies need certain other nutrients in order to use vitamin C effectively.
These include zinc, copper, and other trace minerals. Therefore, it is possible that vitamin C alone may not be enough to lower blood pressure, but it might be beneficial when combined with other nutrients.
The best way to address high blood pressure is to follow a heart-healthy lifestyle. This means eating a balanced diet filled with fruits and vegetables, whole grains, lean proteins, and healthy fats; exercising regularly; and reducing stress levels.
It is also important to speak to your healthcare provider about medications, if necessary. Vitamin C may help support a healthy lifestyle and lower blood pressure, but more research is needed to fully understand the impact it has and how it might best be used in conjunction with other treatments.

What can cause a sudden increase in blood pressure?
These include stress, anxiety, certain medications, changes in diet or activity level, certain medical conditions, and even certain environmental factors. Stress and anxiety can lead to a sudden spike in blood pressure, particularly when it is a sudden or difficult event.
Certain medications like amphetamines, decongestants, and over-the-counter cold or sinus medications can also increase blood pressure, as can some herbal supplements. Changes in diet, such as eating high-sodium foods or large amounts of caffeinated beverages, can also cause a sudden rise in blood pressure.
Additionally, increased activity, such as overexerting oneself while working out or playing a sport, may cause blood pressure to spike. Medical conditions such as kidney disease, heart disease, thyroid disorders, and metabolic syndrome can also cause blood pressure to increase, as can environmental factors like extreme weather or altitude changes.
It is important to speak to a medical professional if you experience a sudden surge in your blood pressure to properly diagnose and treat the cause.
What should you not take with blood pressure medicine?
You should not take any supplements, herbal remedies, or other over-the-counter medications without consulting with your doctor first. This includes anything containing omega-3 fatty acids, as they can raise your blood pressure and interfere with prescribed medications.
You should also not take any medications that may interact with your blood pressure medication, such as tramadol, ibuprofen, naproxen, or aspirin. Additionally, it is important that you avoid foods and beverages that contain a lot of salt or caffeine, as these can also impact your blood pressure levels.
Does vitamin C help lower BP?
Yes, vitamin C is thought to help lower high blood pressure (BP) in some cases. A 2017 review published in Nutrition and Dietary Supplements found that vitamin C supplements can lower systolic and diastolic BP in both adults and children, with the effect being most pronounced in those with hypertension.
Specifically, the vitamin has been shown to reduce BP by 3. 83 to 4. 66/2. 82 to 3. 48 mmHg, respectively. This is thought to be due to its antioxidant activity, which has been found to reduce oxidative stress, improve endothelial dysfunction, and reduce inflammation.
In addition, it can lower blood levels of certain substances linked to higher BP, such as homocysteine, a well-known risk factor for cardiovascular disease. However, low doses of vitamin C are not likely to have any effect on BP, and the impact of higher doses is still being investigated.
Therefore, it’s important to speak with your doctor before taking any supplements for high BP.
What medications does vitamin C interfere with?
Vitamin C can interfere with the absorption and actions of certain medications, including:
– Antifungal medications such as fluconazole, itraconazole, and ketoconazole
– Certain antibiotics like tetracycline, doxycycline, and ciprofloxacin
– Cisplatin, a chemotherapy drug
– Quinolone antibiotics, including ciprofloxacin
– Medications used to lower cholesterol, like cholestyramine and colestipol
– Nelfinavir, a medication used to treat HIV
– Didanosine, an oral medication used in HIV treatment
– Digoxin, used to strengthen heart contractions
– Warfarin, a blood thinner
– Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
– Some birth control pills
– Iron supplements
The exact amount of vitamin C which might interfere with these medications may vary, so it’s important to speak to your doctor or pharmacist before taking it in large doses. Vitamin C can also affect the way the body processes certain medications, so it’s best to take medications and supplements at least two hours apart.
What are the symptoms of too much vitamin C?
The symptoms of having too much vitamin C (also known as vitamin C toxicity) are difficult to pinpoint and can vary depending on the individual and how much vitamin C they have ingested. Generally, they could include nausea, vomiting and stomach discomfort, abdominal cramps, diarrhea, bloating, and headaches.
Extreme vitamin C toxicity may also lead to a condition called oxalate nephropathy, which involves severe kidney damage. There is also a risk of developing kidney stones if too much vitamin C is consumed.
It is important to be aware that some Vitamin C supplements contain other compounds such as magnesium and citric acid, which can also contribute to these symptoms. It is always best to consult a doctor or nutritionist to ensure you are taking the proper amount of Vitamin C.
Who should not take extra vitamin C?
Extra vitamin C should be avoided by people who already get adequate amounts of vitamin C from their diet. People with certain medical conditions should also avoid extra vitamin C. These conditions include hemochromatosis, kidney disease, G6PD deficiency, active liver disease, and thalassemia.
Additionally, some people may be at an increased risk of experiencing side effects from consuming too much vitamin C. This includes those who take medications to lower cholesterol, blood pressure or suppress the immune system, smoke cigarettes, or who have had an organ transplant.
Therefore, it is always important to talk to your doctor before taking any extra vitamin C to make sure it is appropriate for you.
