Cholesterol & Lipid Support Protocol.
A supportive, adjunctive stack that targets LDL cholesterol, triglycerides, and overall lipid balance alongside a heart-healthy diet. It is meant to complement, not replace, prescribed statins or other lipid-lowering therapy, and several ingredients require clinician oversight.
The cholesterol & lipid support protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Cholesterol & Lipid Support Protocol is an intermediate stack of 6 supplements aimed at heart health: Berberine, Fish Oil, Psyllium Husk, Garlic Extract, Vitamin B3, and Nattokinase. 3 are core and the rest are optional add-ons, at roughly $35-60/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the cholesterol & lipid support protocol.
Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.
| Supplement | Dose | Timing | Role | Evidence |
|---|---|---|---|---|
| Berberine | 500 mg, taken 2 to 3 times daily (1000-1500 mg total) | With meals, divided across the day | Core | Moderate |
| Fish Oil | 2000-4000 mg combined EPA and DHA daily | With meals to improve absorption, split into 2 doses | Core | Strong |
| Psyllium Husk | 5-10 g of soluble fiber daily | Before a main meal, with a full glass of water | Core | Strong |
| Garlic Extract | 600-1200 mg of aged garlic extract daily (standardized) | With food, once or twice daily | Optional | Moderate |
| Vitamin B3 | 500-1000 mg of immediate-release niacin (lipid dose), only under clinician supervision | With the evening meal to reduce flushing, starting low and titrating up slowly | Optional | Moderate |
| Nattokinase | 2000 FU (about 100 mg) daily | Once daily, with or without food, ideally in the evening | Optional | Emerging |
Berberine activates AMP-activated protein kinase (AMPK) and may upregulate hepatic LDL receptor expression, which is thought to help lower LDL cholesterol and triglycerides as a diet adjunct. It can interact with several prescription drugs (including some statins) through CYP enzymes and P-glycoprotein, so clinician review is advised.
The omega-3 fatty acids EPA and DHA reduce hepatic VLDL and triglyceride production, which supports lower fasting triglycerides as part of a lipid-focused diet. Doses at the upper end of this range are best monitored by a clinician, since high-dose omega-3 can modestly raise LDL in some people and may affect bleeding risk.
Psyllium is a viscous soluble fiber that binds bile acids in the gut, which prompts the liver to draw down circulating cholesterol to make more bile and modestly lowers LDL. Always take it with ample water and separate it from medications, because its viscous fiber can reduce drug absorption.
Aged garlic extract supplies organosulfur compounds that may produce small reductions in total and LDL cholesterol as a dietary adjunct. Effect sizes are modest and variable across studies, so the evidence is best described as moderate.
At pharmacologic lipid doses, Vitamin B3 (niacin) can lower LDL and triglycerides and raise HDL, but it commonly causes skin flushing and can affect liver enzymes and blood glucose. Large outcome trials have not shown added cardiovascular benefit when niacin is added to statins, so lipid-dose niacin requires clinician oversight and lab monitoring and is never self-prescribed.
Nattokinase is a fermented-soy enzyme studied for fibrinolytic activity and possible lipid-supportive effects, though the cardiovascular and lipid evidence in humans is still limited and emerging. Because it can affect clotting, it should be avoided or used only with clinician approval by anyone taking anticoagulant or antiplatelet medication.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- This stack supports a heart-healthy diet and is not a replacement for prescribed statins or other lipid-lowering therapy. Continue any prescribed treatment and confirm the full combination with your clinician before starting.
- Berberine and Fish Oil act on different pathways (LDL receptor activity and triglyceride production), so pairing them with a heart-healthy diet, rather than relying on any single ingredient, is the foundation of this stack.
- Take Psyllium Husk with a full glass of water and separate it by at least 2 to 4 hours from Berberine, Fish Oil, and any prescription medication, because its viscous fiber can blunt absorption.
- Vitamin B3 (niacin) at lipid doses commonly causes skin flushing and can affect liver enzymes and blood glucose, so it is optional and requires clinician oversight and lab monitoring. Taking it with the evening meal and titrating slowly reduces flushing.
- Nattokinase affects clotting, so use caution and seek clinician approval if you take anticoagulants or antiplatelets, especially when combined with Fish Oil at the higher end of its range, since both can influence bleeding risk.
