Short answer: Gotu Kola stimulates collagen and elastin production, supporting connective tissue integrity and strengthening weakened veins.
Why collagen and elastin production connects to vein strength
These two proteins form the structural foundation of blood vessel walls — supporting their production is a genuinely relevant, checkable mechanism for vein health specifically.
Why this ingredient is grouped under "stress & tissue support"
Motherwort and Gotu Kola are grouped together under this category — addressing stress response and structural tissue integrity as two related, supporting roles.
💡 Worth knowing: strengthening weakened veins is a specific, named benefit of this ingredient — worth understanding alongside the formula's other circulatory ingredients.
