Elastin is a key extracellular matrix protein that provides elasticity and resilience to tissues, notably within the vascular system. Scientific evidence supports its relevance to the structure and function of veins, as elastin fibers are fundamental components of the venous wall, contributing to its flexibility and ability to accommodate changes in pressure and volume. Research has demonstrated that degradation or reduction of elastin content in veins is associated with venous diseases such as varicose veins and chronic venous insufficiency. For example, studies have shown that patients with varicose veins have lower elastin content and altered elastin fiber organization compared to healthy controls (Sansilvestri-Morel et al., 2007).

However, while elastin is scientifically validated as essential for vein structure and function, direct supplementation with elastin or elastin fragments to support vein health in humans is not well-established. Most research focuses on the role of elastin in disease mechanisms or tissue engineering rather than clinical interventions. Some experimental approaches are exploring elastin-based biomaterials for vascular grafts or regenerative medicine, but oral or topical elastin supplementation for vein support lacks robust clinical evidence. Therefore, while elastin is fundamentally important for the venous system, its use as a supplement or treatment is not yet supported by high-level clinical trials.
