Pivotal study from 20 years ago shows you can lower cholesterol without prescription drugs and without changing diet. It's a simple, natural plant compound: berberine. Mechanism is totally different from statins. Changes how to think about cholesterol, LDL, ApoB manipulation.

Statins can decrease GLP-1, cause insulin resistance, risk for type 2 diabetes. Berberine doesn't. Giving the cell more time to produce the LDL receptor protein. LDL cholesterol dropped by 20%. Basically no side effects. Improved markers of liver function.

Always more details in the newsletter. Not a prescription, but excitement for understanding how bodies work for better health.

Six chapters: How statins work, The berberine paradox, Berberine randomized control trial, Berberine versus statins, My next big experiment, Why I wasn't told about this.

Statins inhibit HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis, especially in the liver. This causes cholesterol starvation inside liver cells, depleting the intracellular cholesterol pool.

Liver senses drop in internal cholesterol, activates sterol regulatory element-binding proteins (SREBPs) held outside the nucleus. SREBPs move into nucleus, bind DNA, turn on genes including LDL receptor gene. Gene produces mRNA transcript (blueprint), which makes LDL receptor protein on cell surface. Receptor grabs LDL particles from bloodstream, pulls them into liver to compensate.
