The nattokinase does the heavy lifting. The other seven ingredients aren't filler to pad a label. Each one was picked to work a different lever of the same problem:
Bromelain: a second enzyme that works right alongside nattokinase on the fibrin breakdown.
Grape seed & pine bark extract: support nitric oxide, the compound that lets stiff vessels relax and open.
Aged garlic: a long-studied circulation support.
CoQ10: fuels the heart muscle that's been doing all the extra work.
Turmeric: supports a calmer inflammatory response inside the vessel walls.
Dandelion root: a gentle natural diuretic for the fluid side of the equation.
Clearing, flow, flexibility, fuel, inflammation, fluid. Six angles on one problem, in one capsule. It's the exact stack a lot of people spend a year assembling on their own.
