High blood pressure, or hypertension, affects millions worldwide and is arguably the most significant risk factor for cardiovascular disease. While lifestyle modifications remain crucial, certain supplements may have promise in supporting healthy blood pressure levels. This post explores the potential of the best supplements for high blood pressure, focusing on natural solutions with scientific backing.
Key takeaways
- Several supplements have shown some potential in supporting healthy blood pressure levels, including CoQ10, fish oil, and garlic
- The effectiveness of supplements varies significantly, with some showing more consistent results than others
- Supplements cannot replace prescribed medications or lifestyle changes but may be used as complementary approaches
1. Coenzyme Q10 (CoQ10)
CoQ10 is an antioxidant that plays a crucial role in energy production in cells. It may help lower blood pressure by reducing oxidative stress and improving endothelial function.
Studies have found that CoQ10 supplementation may lower systolic blood pressure by a mean −4.77 mmHg. In some of the studies included in the largest meta-analysis to date, patients with essential hypertension who took CoQ10 for more than 10 weeks experienced statistically significant decreases in both systolic and diastolic blood pressure.
Typical dosages range from 100-200 mg per day. CoQ10 is generally well-tolerated, but some people may experience mild side effects such as stomach upset or headaches.
2 Fish oil (Omega-3 fatty acids)
Omega-3 fatty acids, particularly EPA and DHA found in fish oil, may help lower blood pressure by reducing inflammation and improving blood vessel function.
Research suggests that fish oil supplementation can reduce systolic blood pressure by about -2.56 mmHg. Some of the studies in one of the largest systematic reviews on the topic found that after 2 months of supplementation, both systolic and diastolic blood pressure decreased by -4-5 mm Hg in both hypertensive and normotensive subjects taking fish oil.
A common dosage is 1-2 grams of EPA + DHA per day. Side effects may include fishy aftertaste, bad breath, or digestive discomfort.

High doses may increase bleeding risk.
3. Garlic supplements
Garlic is thought to work by causing smooth muscle relaxation and vasodilation, which can help lower blood pressure. A study found that garlic supplementation may lower systolic blood pressure by 7-8 mmHg and diastolic blood pressure by 5 mmHg compared to placebo.
Dosages vary, but often range from 600-1,200 mg of aged garlic extract per day. Side effects may include bad breath, digestive upset, or increased bleeding risk.
4. Beetroot juice
Beetroot juice is high in nitrates, which can be converted to nitric oxide in your body. Nitric oxide helps dilate blood vessels, potentially lowering blood pressure.
Studies have suggested that beetroot juice may help slightly reduce blood pressure. The nitrates in beetroot juice are converted to nitric oxide in your body, which can help dilate blood vessels.
Typical dosages in studies range from 250-500 ml of beetroot juice daily. Side effects may include pink urine or stools, which is harmless.
5. Magnesium
Magnesium plays a role in regulating blood pressure by helping to relax blood vessels and maintain proper heart rhythm. Magnesium supplementation may have a modest effect on lowering blood pressure, particularly in people with magnesium deficiency.
Typical dosages range from 200-400 mg per day. High doses may cause diarrhea or other digestive issues.

6. Potassium
Potassium helps balance sodium levels in your body and promotes proper blood vessel function. Increased potassium intake, either through diet or supplements, may help lower blood pressure in some people.
Dosages vary, but should be determined by a healthcare provider. Excess potassium can be dangerous, especially for those with kidney problems.
Supplement | Potential BP Reduction (Systolic) | Strength of Evidence |
---|---|---|
CoQ10 | 5-6 mmHg | Moderate |
Fish Oil | 2-3 mmHg | Weak to Moderate |
Garlic | 7-8 mmHg | Moderate |
Beetroot Juice | Variable | Weak |
Magnesium | Modest | Moderate |
Potassium | Variable | Moderate |
Other promising supplements
While the above supplements have the strongest evidence, some other natural options have shown potential in early research:
- L-arginine: An amino acid that may help produce nitric oxide
- Hibiscus tea: May have a mild blood pressure-lowering effect
- Aged black garlic: A fermented form of garlic with potential cardiovascular benefits

Final thoughts
While lifestyle modifications remain the cornerstone of blood pressure management, certain supplements show promise as complementary approaches. CoQ10, fish oil, and garlic supplements have demonstrated the most consistent benefits in research studies. However, it's important to remember that supplements are not a magic solution and should be part of a comprehensive approach to blood pressure management.
Always consult with a healthcare professional before starting any new supplement regimen. They can help you determine the most appropriate supplements based on your individual health needs and ensure they don't interact with any medications you may be taking.
