How this protocol works

In plain language

Atherosclerosis is the buildup of cholesterol-rich plaques in arteries, driven by inflammation, oxidized LDL, and arterial calcification. This protocol targets all three mechanisms.

  • Berberine is as effective as statins for lowering LDL cholesterol (15-20% reduction) but works through different mechanisms—it activates AMPK and increases LDL receptor expression. It also reduces arterial inflammation.
  • Omega-3s (EPA/DHA) reduce triglycerides by 25-30%, stabilize existing plaques (making them less likely to rupture), and reduce the inflammation that drives plaque formation. The REDUCE-IT trial showed high-dose EPA reduced cardiovascular events by 25%.
  • Aged garlic extract has been shown in CT imaging studies to slow plaque progression by 80% compared to placebo over 12 months.
  • Vitamin K2 directs calcium away from arteries and into bones. Low K2 status is associated with arterial calcification.
  • Niacin raises HDL ("good" cholesterol) and is the only agent that significantly lowers Lp(a), an independent risk factor.
  • CoQ10 protects LDL particles from oxidation—it's oxidized LDL that gets deposited in artery walls.

Expected timeline: Lipid improvements in 4-8 weeks. Plaque stabilization/regression requires 12+ months of consistent use.
