What are the real Benefits of Omega-3 fatty acids on Heart Health?

by Bartosz Olechowski • 17 January 2025
The evidence supporting Omega-3 for heart health is not as convincing as initially thought, though not without promise, especially in a form of Icosapent Ethyl. Improving cardiovascular wellness appears to be mediated by reduction in triglycerides levels, which indeed are a risk factor for heart disease. However, the magnitude of these benefits can vary based on individual factors such as baseline risk and underlying past medical history. For individuals considering Omega-3 supplements, consulting a healthcare provider is essential to ensure appropriate use. Professionals like Dr Bart, with expertise in advanced diagnostic tests and personalised care, can guide patients toward optimal heart health. Ultimately, there are several valuable tools that can help in the fight against cardiovascular disease. The broader lifestyle changes and medical care is something that we would recommend.
