Over half of adults in the U.S. rely on medications to manage their blood pressure. If you’re among them, you might encounter discussions about supplements you can take without a prescription. The topic of supplements often sparks divided opinions; some advocate for their natural benefits while others dismiss them as unproven. Dr. Majid Basit, a cardiologist at Memorial Hermann, encourages a balanced view.
He points out that supplements are often overhyped in advertising, with manufacturers playing down any risks. His approach is to help patients find a middle ground between prescribed medications and over-the-counter supplements.
This is a conversation worth having with your healthcare provider, particularly the one prescribing your blood pressure medication. Dr. Basit emphasizes that supplements are not as strictly regulated as prescription drugs. This means that the quality and dosages can differ widely between brands, potentially leading to varied effects. Additionally, mixing supplements with blood pressure medications could result in negative side effects.
Dr. Mary Greene, a cardiologist with Manhattan Cardiology, adds that the repercussions can range from medications losing effectiveness to severe side effects. “Natural” or over-the-counter doesn’t mean something is inherently safe when combined with prescribed treatments.
Fish oil is one supplement often described as heart-healthy. However, cardiologists warn that taking it alongside blood pressure medication without consulting your doctor might not be a wise decision. Let’s look at a few reasons why.
The Supplement To Avoid Taking With Blood Pressure Medication
Cardiologists urge caution regarding fish oil if you’re on blood pressure medication. While it’s often marketed as beneficial for heart health, it can negatively interact with hypertension treatments.
1. Fish oil may have a blood-thinning effect
Dr. Kevin Shah, a certified cardiologist, notes that fish oil can cause a mild blood-thinning effect. Most studies suggest that this isn’t an issue at standard doses, but higher doses might elevate the risk.
2. It may lower blood pressure too much
Fish oil has the potential to lower blood pressure slightly, especially when paired with blood pressure medications. The intent of these medications is to keep blood pressure within a healthy range. When fish oil supplements are added into the mix, they may cause blood pressure to drop too low, leading to symptoms like dizziness.
3. You may take too much fish oil with BP medications
Dr. Greene expresses concern about the mindset some people have that “more is better” when it comes to supplements. Many assume that if a small amount is good, a larger amount must be even better, often without informing their healthcare provider.
4. It might be rancid
A less appealing concern about fish oil is that some supplements can be rancid. Dr. Patrick Kee, a preventive cardiologist, highlights that omega-3 fatty acids can degrade easily when exposed to light, heat, and air. Rancid oils can lose their intended benefits, whereas prescription options usually have stricter processing standards to mitigate oxidation.
Can You Ever Take Fish Oil While on Blood Pressure Medication?
Most cardiologists won’t outright ban fish oil for those on blood pressure medication. However, they advise individual consultations since the interaction can vary. Dr. Shah mentions that it’s generally safe, but caution is necessary for those who may have already low blood pressure.
It’s important to consult your doctor before adding supplements like fish oil if you’re on hypertension medication. Report any unusual side effects promptly, as this helps your healthcare provider monitor and adjust your treatment as needed.
Why You May Not Even Need Fish Oil for Heart Health
Instead of relying on fish oil supplements, many cardiologists suggest focusing on diet and lifestyle changes for better heart health. Dr. Kee states that a balanced diet can provide the same cardiovascular benefits associated with omega-3 fatty acids.
The Dietary Guidelines for Americans recommend that adults consume at least eight ounces of various seafood weekly for heart health. Dr. Greene lists several food sources rich in EPA and DHA.
- Fatty fish like salmon
- Walnuts
- Flaxseeds
- Chia seeds
- Algal oil
- Hemp seeds
Making positive lifestyle adjustments, such as increasing physical activity and managing weight, can yield even more substantial health improvements than fish oil alone could. Dr. Basit reiterates that quitting smoking and treating conditions like high cholesterol and diabetes significantly reduce the risk of cardiovascular issues.
