Omega Blend supplements typically contain a mixture of omega-3 and omega-6 fatty acids, often derived from sources such as fish oil, flaxseed oil, and other plant oils. The scientific rationale for using omega fatty acids to support capillary and overall vascular health is primarily based on their well-documented effects on endothelial function, inflammation, and blood lipid profiles. Several studies have shown that omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), can help reduce inflammation in blood vessels, improve endothelial function, and decrease blood viscosity, all of which can support the integrity and function of capillaries.

A 2014 review in the journal BioMed Research International highlighted that omega-3 supplementation is associated with improved microcirculatory function and may enhance capillary blood flow. Additionally, omega-3 fatty acids have been shown to reduce the risk of atherosclerosis and thrombosis, conditions that can compromise capillary health.

However, the direct evidence specifically linking “Omega Blend” supplements to capillary health (as opposed to general cardiovascular benefits) is moderate rather than strong. Most clinical trials focus on broader cardiovascular outcomes rather than specifically on capillaries. Thus, while there is a scientific basis for their vascular support, the evidence is indirect when it comes to capillaries per se.
