Fish Oil Supplements and Heart Health:

A Frequently Asked Questions (FAQ) section is provided at the end of this article.

To Healthcare Practitioners,

We recently reviewed the study published in the BMJ Medicine journal (BMJ) and titled "Regular use of fish oil supplements and course of cardiovascular diseases: prospective cohort study" by Chen et al. (2024). This study has garnered significant attention from major media outlets regarding the potential risks associated with fish oil supplements, particularly an increased risk of atrial fibrillation (AFib)(1). While it is important to consider these findings, it is equally vital to evaluate the broader scientific evidence and overall benefits of omega-3 supplementation. Our goal is to provide a balanced perspective and address the concerns raised, ensuring that practitioners have a comprehensive understanding of the evidence surrounding fish oil supplements like MAG-O3™.

Key Findings from the BMJ Study

The BMJ study examined the potential risks associated with regular use of fish oil supplements, particularly focusing on the incidence of AFib among individuals without pre-existing cardiovascular disease. Here are the key findings:

• Potential Increased AFib Risk: The study observed a 13% increased risk of developing AFib among regular fish oil users without pre-existing cardiovascular conditions. This finding was derived from observational data within the UK Biobank, a large-scale biomedical database.
• Potential Benefits for Disease Progression in Existing AFib: For individuals that developed AFib during the course of this study, it is suggested that regular fish oil supplementation may be associated with a potential reduction in progression from AFib to major adverse cardiovascular events (MACE) and from AFib to death.*
• Observational Nature: As an observational study, it highlights associations but does not establish causality. This means while there is an association between fish oil use and AFib, it does not prove that fish oil causes AFib.
• Population Studied: The study analyzed data from a substantial cohort within the UK Biobank, enhancing the reliability of its findings but also highlighting its specific population context.

Limitations of the BMJ Study

1. Observational Nature: The study identifies associations but does not establish causality.
2. Confounding Variables: Factors such as participants' baseline health and lifestyle may influence both fish oil use and AFib risk.
3. Self-Reported Data: The accuracy of self-reported fish oil consumption may be compromised by recall bias.
4. Dose and Duration: The study lacks detailed information on the dosage and duration of fish oil use.
5. Types of Omega-3: The study does not differentiate between various forms of omega-3 supplements (FFA, EE vs TG vs rTG), which can have varying effects.

By understanding these limitations, we can better contextualize the BMJ study's findings and address the concerns they raise.

Understanding AFib

Atrial fibrillation (AFib) is a condition characterized by an irregular and often rapid heart rate, which can lead to blood clots in the heart. These clots can increase the risk of stroke, heart failure, and other heart-related complications. Symptoms of AFib can include heart palpitations, shortness of breath, and weakness, although some individuals may not experience any symptoms.

Insights from Recent Reviews and Experts

2023 Review by Huh et al.

A comprehensive review published in 2023 by Huh et al. provides a nuanced perspective on the relationship between omega-3 supplementation and AFib(2). Key conclusions from the review include:

• High Doses and AFib Risk: The review suggests that high doses (>1.8g/day) of omega-3s may increase the risk of AFib, although it also notes substantial overall cardiovascular benefits.*
• Potential Pro-Arrhythmic Effects: The review suggests that the potential pro-arrhythmic effects of high-dose omega-3s are related to the modulation of ion channels and electrical activity in the atrial myocardium.
• Personalized Medicine: The importance of personalized medicine is emphasized, recommending tailored omega-3 supplementation based on individual patient profiles to optimize benefits and minimize risks.

2024 Study by O'Keefe et al.

The study by O'Keefe et al. (2024) further explores the relationship between omega-3 blood levels and stroke risk(3). Key findings include:

• Lower Stroke Risk: The study suggests that higher levels of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are associated with a lower risk of total and ischemic stroke.*
• No Increased Hemorrhagic Stroke Risk: The study found no association between high omega-3 levels and an increased risk of hemorrhagic stroke.*
• Consistent Benefits: The protective effects against stroke were consistent across different population subgroups, including those with and without preexisting cardiovascular diseases.*

Insights from Dr. Bill Harris and Dr. Kristina Harris Jackson

Dr. Bill Harris, an omega-3 expert, explained in a recent podcast that habitual fish oil use was associated with a 10% increase in AFib risk, regardless of genetic predisposition, but only in those without baseline cardiovascular disease(4). He emphasized that seven out of eight UK Biobank studies showed significant health benefits from omega-3s, including reduced risks of type 2 diabetes, fractures, dementia, primary liver cancer, and total mortality.

Dr. Kristina Harris Jackson added, "You're not supposed to take your diet and health advice from large epidemiology studies, but how do you balance the good news with the AFib news?" Dr. Harris responded, "If it protects you against 15 other adverse outcomes, then a 1% increase in absolute risk might be worth the balance."*

GOED's Position on Fish Oil and AFib Risk

In response to recent discussions on the potential link between fish oil supplementation and an increased risk of atrial fibrillation (AFib), the Global Organization for EPA and DHA Omega-3s (GOED) has issued a statement. GOED emphasizes that the overall body of evidence supports the cardiovascular benefits of omega-3 fatty acids, such as EPA and DHA, while noting that the observed increase in AFib risk is relatively small. GOED advises healthcare practitioners to consider the broader context of omega-3 benefits and to tailor their recommendations based on individual patient needs, especially considering the potential cardiovascular advantages that outweigh the slight AFib risk increase for most individuals(32).

Safety Considerations and Omega-3 Recommended Intakes and Upper Limits

The safety of omega-3 supplementation is paramount, and it is important to adhere to guidelines set by major health organizations. Recommended intakes and upper limits for omega-3 fatty acids, particularly EPA and DHA, have been established by several authoritative bodies:

• Health Canada recommends that daily intakes of combined EPA and DHA should not exceed(5):
• Adults (18 years and older): Up to 5,000 mg per day
• Adolescents (14-17 years): Up to 2,500 mg per day
• Children (1-13 years): Up to 1,500 to 2,000 mg per day depending on age.
• The U.S. Food and Drug Administration (FDA) has determined that omega-3 intakes of up to 3 grams per day from supplements are generally recognized as safe (GRAS)(6).
• The European Food Safety Authority (EFSA) has set an upper limit of 5 grams per day for combined EPA and DHA from all sources(7).
• The American Heart Association (AHA) suggests that people without documented coronary heart disease should consume about 500 milligrams of EPA and DHA per day (2 fatty fish at lest twice per week)(8), while those with coronary heart disease should take 1 gram per day, preferably from fatty fish(9). For patients needing to lower triglycerides, 2 to 4 grams of EPA and DHA per day provided as capsules under a physician's care is recommended(10).
• The Global Organization for EPA and DHA Omega-3s (GOED) make the following recommendations(11):
• General Healthy Adult Population: 500 mg to lower the risk of coronary heart disease (CHD).
• Pregnant and Lactating Women: 700-1000 mg with at least 300 mg being DHA to support optimal health.
• Secondary Prevention of CHD: 1000 mg of EPA + DHA.
• Additional Health Conditions: Higher intakes (greater than 1 gram) are supported for conditions such as blood pressure regulation and triglyceride levels.

Benefits of Omega-3 Fatty Acids

Omega-3 supplements have been extensively studied and are considered a valuable part of a balanced health regimen. Here are some potential benefits of omega-3 supplementation:

Cardiovascular Health: Studies suggest that omega-3s, particularly EPA and DHA, may help maintain healthy blood pressure levels, support healthy triglyceride levels, and promote overall heart health(12-15).*

Cognitive Function: DHA is an important structural component of the brain and may support cognitive function across all ages, including memory and learning in children and cognitive health in older adults(16).*

Anti-Inflammatory Effects: Omega-3s have been shown to play a role in the body's natural inflammatory response, which may help support joint health and overall well-being(17).*

Prenatal Health: During pregnancy, DHA is important for the development of the fetal brain, eyes, and nervous system. Omega-3 supplementation may support maternal and fetal health(18,19).*

Eye Health: DHA is a major structural component of the retina, and adequate levels may help in slowing the progression of wet age-related macular degeneration and may significantly improves dry eye symptoms and signs in patients with dry eye disease. (20,21).*

Mental Health: Emerging research suggests that omega-3s may support mental health by influencing neurotransmitter pathways and supporting the body's natural inflammatory response(22). They may help maintain a healthy mood and improve symptoms of ADD and ADHD in children (23-25).*

Joint Health: Omega-3s may help support joint health by supporting the body's natural inflammatory response, which can contribute to improved mobility and comfort(26).*

Omega-3 supplements are an important part of a health regimen, supporting various aspects of health such as cardiovascular, cognitive, inflammatory, prenatal, eye, mental, and joint health. Incorporating omega-3s into daily routines may contribute to overall health and well-being.*

Personalized Health Approaches: The Omega-3 Index

The Omega-3 Index measures the combined percentage of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in red blood cell membranes, reflecting an individual's omega-3 status and predicting cardiovascular health. Introduced by Harris and von Schacky in 2004, it has become a vital tool for evaluating coronary heart disease (CHD) risk(27). Higher Omega-3 Index levels correlate with improved cardiovascular biomarkers, such as increased high-density lipoprotein (HDL) cholesterol and reduced triglyceride levels.* Conversely, lower levels are linked with higher cardiovascular risk factors like increased body mass index (BMI) and smoking.*

Maintaining an optimal Omega-3 Index, typically 8% or higher, provides significant cardiovascular benefits.* Incorporating omega-3s into red blood cell membranes enhances blood flow, reduces inflammation, and decreases triglycerides, offering substantial cardiovascular protection(28).*

Given recent concerns about the potential link between fish oil supplementation and an increased risk of atrial fibrillation (AF), the Omega-3 Index provides a personalized approach to manage these risks. Regularly measuring and monitoring the Omega-3 Index allows individuals to tailor their omega-3 intake to maintain optimal levels, balancing benefits and potential risks. Tools like the Omegaquant Omega-3 Index Test Kit enable consumers to accurately measure their omega-3 levels and tailor their supplementation accordingly, ensuring optimal health outcomes and addressing individual health needs effectively.

Using the Omega-3 Index as part of a personalized health strategy supports the safe and effective use of omega-3 supplements.
