in pictures and a few words
What it is and why it matters
Cholesterol is the body’s building material, not dirt in the blood. Total cholesterol alone can’t show the risk to your blood vessels — more precise tests are needed.
- It is part of the membrane of every cell and of the sheaths around nerves
- The body uses it to make sex hormones, adrenal hormones, bile and vitamin D
- About a quarter of all the body’s cholesterol is in nerve tissue
One number — different particles
Total cholesterol is made up of different particles. Two people with the same total cholesterol of 6.2 mmol/L can have very different risk.
- “Good” cholesterol carries the excess from the vessel wall to the liver — it protects
- What matters most is the number of “bad” cholesterol particles — a precise test counts it
- Small dense particles get into the vessel wall more easily
A test that counts particles
There is a test that counts the particles able to leave cholesterol in the vessel wall. It predicts risk better than total cholesterol.
- Target — below 90 mg/dL (0.9 g/L); at higher risk the doctor sets a lower target
- Small dense and oxidized particles, inflammation and blood sugar are checked too
- Repeated every 6–12 months, then once a year
The inherited particle
There is a special cholesterol particle: its level is set by genes and changes little over a lifetime. It is enough to check it once.
- Target — below 30 mg/dL (0.3 g/L) or below 75 nmol/L
- Over 50 mg/dL (0.5 g/L) — see a doctor: more risk of heart attack and aortic valve narrowing
- If it’s high, blood pressure, inflammation and other tests are kept especially tight
What makes particles more dangerous
Particles of “bad” cholesterol are more dangerous when they oxidize. Clean-up cells swallow them without limit and become the core of a future plaque.
- Trans fats, tobacco smoke and high blood sugar oxidize the particles
- Small dense particles appear when the body responds poorly to insulin
- An inflammation protein above 2 mg/L on repeat tests — see a doctor
Food for your blood vessels
Mediterranean eating: olive oil, fish, vegetables, nuts and legumes.
- Cut out trans fats: margarine, fast food
- Fewer fast carbs and less fructose
- Berries, green tea and dark chocolate
Movement, sleep and fish oil
Endurance exercise of 150 minutes a week or more raises “good” cholesterol and lowers triglycerides — blood fats.
- Strength training 2–3 times a week helps the body respond better to insulin
- Sleep 7–8 hours: sleeping less than 6 raises inflammation and triglycerides
- Omega-3, 2–4 g a day (count the omega-3 itself, not the capsules), lowers triglycerides
Cholesterol pills
The article is not against cholesterol pills — they are justified in the cases below. At low risk by precise tests and a heart scan, they are rarely needed for prevention.
- “Bad” cholesterol above 190 mg/dL (≈ 4.9 mmol/L), including inherited
- Already had a heart attack or stroke; a heart scan showed vessel calcium above 100
- Type 2 diabetes together with other risk factors
Important. Already taking cholesterol pills? Don’t stop them on your own. The decision is made with your doctor, not by a single number.
Who should see a doctor first
Discuss checking your blood vessels with a doctor if at least one of these applies. Any supplements — also with a doctor first.
- Heart attack, stroke or heart disease in relatives before age 60
- Total cholesterol above 6.2 mmol/L without precise tests; triglycerides above 1.7 mmol/L (150 mg/dL)
- Prediabetes, type 2 diabetes, waist over 94 cm in men or 80 cm in women
Important. Cholesterol pills prescribed without extended tests? Discuss it with a doctor, but don’t stop them on your own.
In one sentence
The body needs cholesterol, and extended tests show the risk to your blood vessels more precisely. Food, movement and sleep help, and pills are decided together with a doctor.
Introduction: A Slandered Ally
When a patient receives a lipid panel marked “total cholesterol 6.2 mmol/L,” in most offices this automatically leads to a statin prescription. Yet total cholesterol is an extremely limited metric. About 25% of all cholesterol in the body is found in nervous tissue, where it forms myelin sheaths. Sex hormones, cortisol, aldosterone, bile acids, and vitamin D are impossible without cholesterol.
It is not a “pollutant,” but a structural material. LDL (low-density lipoprotein) cholesterol is not the only marker: ApoB and particle number reflect risk more accurately. Oxidation, inflammation, glycation, and a shift in the lipoprotein profile toward small dense particles amplify their harm.
This article explains why total cholesterol is misleading, which subfractions truly determine risk, and what an extended lipid panel looks like in my practice.

What Cholesterol Does in the Body
Before discussing “lowering,” it is important to understand what is being lowered:
▸Structural basis of the cell membrane — cholesterol ensures membrane fluidity and the function of membrane receptors (insulin, thyroid, adrenergic receptors). ▸Precursor of sex hormones — testosterone, estradiol, and progesterone are synthesized from cholesterol via pregnenolone. ▸Precursor of glucocorticoids and mineralocorticoids — cortisol and aldosterone are impossible without cholesterol. ▸Raw material for bile acids — without them, absorption of fat-soluble vitamins (A, D, E, K) is impaired. ▸Precursor of vitamin D — synthesis in the skin under UV exposure requires 7-dehydrocholesterol. ▸Myelin sheaths of nerves — about 25% of all body cholesterol is located in the CNS.
When HMG-CoA reductase is aggressively suppressed by a statin, all these functions are affected at the same time. This is not an argument against statins as a class; it is an argument against hunting a total cholesterol number in isolation without assessing real risk.
🌀
Why Total Cholesterol Is Misleading
Total cholesterol ≈ HDL + LDL + triglycerides/5 (in mg/dL; in mmol/L, triglycerides/2.2). It is an arithmetic sum that combines fundamentally different particles:
▸HDL — anti-atherogenic particles that remove cholesterol from the vascular wall back to the liver. High HDL is a protective factor. ▸Large buoyant LDL — penetrate the endothelium less easily than small dense particles; risk still reflects the total particle number (ApoB). ▸Small dense LDL (sdLDL) — atherogenic particles that easily penetrate the subendothelial space and undergo oxidation. ▸Lp(a) — an independent genetic risk factor not reflected in a standard lipid panel. ▸Triglycerides — an indicator of insulin resistance and rapid carbohydrate intake.
Two patients with the same total cholesterol of 6.2 mmol/L may have fundamentally different risks. One has high HDL, low ApoB, and low Lp(a) — low risk. The other has low HDL, high sdLDL, Lp(a) > 100 nmol/L, and hsCRP 4 mg/L — catastrophic risk. The total cholesterol number is the same.
ApoB <90 mg/dL predicts cardiovascular risk better than total cholesterol (Sniderman AD, JAMA Cardiol 2019, PMID 31642874). Each atherogenic particle (LDL, VLDL, Lp(a)) carries exactly one apolipoprotein B-100 protein. ApoB concentration = the number of atherogenic particles. This is a direct quantitative risk marker.
🌀
What Amplifies the Harm of LDL Particles
An LDL particle is a transport container for cholesterol. LDL cholesterol is not the only marker; ApoB and particle number reflect risk more accurately. Oxidation, inflammation, and glycation amplify the harm of the particles in the vascular bed.
•Oxidation — by products of trans fats (partially hydrogenated oils), tobacco smoke, and hyperglycemia. Oxidized LDL (oxLDL) is recognized by macrophage scavenger receptors that lack saturation feedback. Macrophages absorb oxLDL without restriction and become foam cells — the core of a future plaque. •Inflammation — elevated hsCRP (high-sensitivity C-reactive protein) activates endothelial adhesion molecules (VCAM-1, ICAM-1), attracts monocytes, and increases macrophage uptake of oxLDL. hsCRP > 3 mg/L is associated with high vascular risk. •Glycation — high glucose (HbA1c > 6%) glycates ApoB, the LDL particle protein. Glycated LDL is recognized less effectively by hepatic LDL receptors, circulates longer, and oxidizes more easily. •Small dense particles (sdLDL) — form in insulin resistance and high triglycerides. An sdLDL size <25.5 nm allows them to pass through the endothelium more easily than large buoyant LDL. This is the main atherogenic subfraction shift. •Homocysteine — high homocysteine (>10 μmol/L) damages the endothelium and promotes LDL oxidation. •Antioxidant deficiency — low vitamin C, a low omega-3 index, and low glutathione reduce LDL resistance to oxidation.
This is the logic of the md_pereligyn protocol: look at ApoB and particle number, not only at LDL cholesterol, and remove the oxidative and inflammatory context that amplifies the harm of the particles.

Extended Lipid Panel: What to Order
A standard lipid panel (total cholesterol, HDL, calculated LDL, triglycerides) is the minimum from the 1980s. Modern vascular screening includes:
| Marker | Target |
|---|---|
| ApoB | <90 mg/dL (0.9 g/L) |
| ApoA1 | >120 mg/dL (1.2 g/L) |
| sdLDL-C | <25 mg/dL |
| oxLDL | <60 U/L |
| Lp(a) | <30 mg/dL (0.3 g/L) |
| hsCRP | <1 mg/L |
▸ApoB — target <90 mg/dL (low risk), <80 mg/dL (moderate risk), <70 mg/dL (high risk). A direct count of atherogenic particles. ▸ApoA1 — target >120 mg/dL. The main HDL protein. ▸ApoB / ApoA1 ratio — target <0.7. Predicts risk better than the total cholesterol-to-HDL ratio. ▸Small dense LDL (sdLDL-C) — target <25 mg/dL. Available in major laboratories (Quest, LabCorp, Synevo). ▸Oxidized LDL (oxLDL) — target <60 U/L. A direct marker of atherogenic particle modification. ▸Lp(a) — target <30 mg/dL (or <75 nmol/L). Tested once in a lifetime — genetically determined and changes little over life. >50 mg/dL is an independent risk factor for myocardial infarction and aortic stenosis. ▸Triglycerides/HDL — target <2.0 (mg/dL) or <0.87 (mmol/L). An indirect indicator of insulin resistance and sdLDL predominance. ▸hsCRP — target <1 mg/L. A marker of systemic inflammation. ▸Homocysteine — target <8 μmol/L. A marker of methylation and endothelial toxicity. ▸HbA1c, fasting insulin, fasting glucose — assessment of the glycation context. ▸Omega-3 index — target >8%. A marker of membrane protection from oxidation.
In my practice, I order this panel at the first vascular risk consultation. Total cholesterol alone is a 1985 diagnosis.

A Holistic Protocol for Reducing Vascular Risk
Principle: treat the context, not the number. Restore endothelial function, reduce oxidative burden, and decrease sdLDL and oxLDL.
1. Nutrition Against Oxidation and Glycation
▸Mediterranean pattern — olive oil, fish, vegetables, nuts, legumes. In PREDIMED, among people aged 55–80 at high cardiovascular risk, a Mediterranean diet with extra-virgin olive oil or nuts reduced major cardiovascular events (MI, stroke or cardiovascular death combined) by about 30% versus a reduced-fat diet (Estruch R, NEJM 2018, PMID 29897866). ▸Eliminate trans fats — partially hydrogenated oils, margarine, fast food. In a meta-analysis of 60 controlled trials, replacing trans fats with unsaturated fats or carbohydrates improved the total-to-HDL cholesterol ratio almost twice as much as replacing saturated fats (Mensink RP, Am J Clin Nutr 2003, PMID 12716665). ▸Limit omega-6 — sunflower, corn, and soybean oil. A shift in the omega-6/omega-3 ratio toward a pro-inflammatory profile. ▸Limit rapid carbohydrates and fructose — increase triglycerides, sdLDL formation, and ApoB glycation. ▸Polyphenols — berries, dark chocolate (>70%), green tea, red wine in moderate amounts.
2. Antioxidant Protection of the LDL Particle
▸Vitamin E supplements are not recommended for vascular protection: in a meta-analysis of 19 trials, doses of 400 IU/day or more were associated with higher all-cause mortality (Miller ER, Ann Intern Med 2005, PMID 15537682); there is no evidence that mixed tocopherols are safer. ▸Vitamin C 500–1000 mg/day — regenerates oxidized vitamin E. ▸Coenzyme Q10 (ubiquinol) 100–200 mg/day — especially during statin therapy (statins suppress CoQ10 synthesis). ▸N-acetylcysteine (NAC) 600–1200 mg/day — a glutathione precursor.
3. Omega-3 — Reducing Triglycerides and sdLDL
▸EPA+DHA 2–4 g/day — triglyceride reduction by 25–35%, with a shift in LDL distribution toward large buoyant particles. ▸In the REDUCE-IT trial, 4 g EPA (icosapent ethyl) reduced cardiovascular events by 25% in patients with triglycerides 135–499 mg/dL (Bhatt DL, NEJM 2019, PMID 30415628). ▸Check the omega-3 index every 4–6 months; target >8%.
4. Milk Thistle and Bergamot — Native Ligands
▸Bergamot (citrus extract) 500–1000 mg/day — lowers LDL by 15–25% and raises HDL. The active components — brutieridin and melitidin — inhibit HMG-CoA reductase more gently than statins. ▸Milk thistle (silymarin) 200–400 mg/day — supports hepatic lipid metabolism.
5. Lowering Lp(a)
Lp(a) is genetically determined, and most classic interventions do not affect it.
▸Niacin (nicotinic acid) 1–2 g/day — lowers Lp(a) by 20–30%, but tolerability is poor (flushing, hepatotoxicity). I do not recommend it without medical supervision. ▸Icosapent ethyl (purified EPA) 4 g/day — modest reduction, with the main effect mediated through oxPL-apoB. ▸The future: pelacarsen (antisense oligonucleotide) — clinical trials show an 80% reduction in Lp(a). FDA approval is expected in the coming years. ▸Today, the main strategy for high Lp(a) is aggressive control of all other risk factors (ApoB, hsCRP, BP).
6. Movement and Insulin Sensitivity
▸Aerobic exercise 150+ min/week — raises HDL and lowers triglycerides. ▸Resistance training 2–3 times/week — improves insulin sensitivity and reduces the sdLDL fraction. ▸HIIT — in adapted patients, produces the strongest effect on the omega-3 index and triglycerides.
7. Sleep and Stress
▸Sleep 7–8 hours — less than 6 hours increases hsCRP and triglycerides. ▸Cortisol control — chronic stress increases BP, insulin resistance, and the pro-inflammatory background.
8. Statins — When They Are Justified
I am not against statins as a class. They are justified in:
▸Familial hypercholesterolemia (LDL >190 mg/dL (≈ 4.9 mmol/L), genetically confirmed) ▸LDL >190 mg/dL (≈ 4.9 mmol/L) regardless of other factors ▸CAC-score >100 Agatston units ▸Prior myocardial infarction or stroke (secondary prevention) ▸Type 2 diabetes combined with other risk factors
They are not justified for primary prevention in patients with low real risk (low ApoB, low sdLDL, low hsCRP, CAC = 0), even if total cholesterol is 6.5 mmol/L.
🌀
What Does NOT Work (and Why)
▸Isolated lowering of total cholesterol without assessing subfractions — the patient may still have high ApoB, sdLDL, and Lp(a) despite “normal” total cholesterol. ▸Low-fat diet — increases triglycerides, lowers HDL, and increases the sdLDL fraction. ▸Replacing saturated fats with omega-6 (sunflower oil) — does not reduce cardiovascular mortality (Ramsden CE, BMJ 2016, PMID 27071971). ▸High-dose vitamin E (≥400 IU/day) — may increase all-cause mortality (Miller ER, Ann Intern Med 2005, PMID 15537682). ▸Aspirin “just in case” for primary prevention — USPSTF 2022 recommends against starting it at 60 or older (no net benefit); at 40–59 with 10-year CVD risk ≥10% the net benefit is small and the decision is individual (Davidson KW, PMID 35471505). ▸Phytosterols in large doses — lower LDL, but increase cholesterol absorption into the endothelium, which creates an ambiguous net effect on plaque. ▸Trusting total cholesterol alone as a target — this is an outdated model.
🌀
When to Seek Care
▸Family history of CHD, myocardial infarction, or stroke before age 60 ▸Total cholesterol >6.2 mmol/L when ApoB, sdLDL, and Lp(a) are unknown ▸Lp(a) > 50 mg/dL (0.5 g/L) ▸Repeated hsCRP > 2 mg/L ▸Metabolic syndrome, prediabetes, type 2 diabetes ▸Triglycerides > 150 mg/dL (≈ 1.7 mmol/L) ▸Waist circumference > 94 cm (men) / > 80 cm (women) ▸A statin prescription without an extended lipid panel and CAC-score
I perform full vascular screening (ApoB, sdLDL, oxLDL, Lp(a), hsCRP, omega-3 index, homocysteine, HbA1c, insulin) and create a personalized protocol to reduce real risk, not the total cholesterol number.
🌀
Conclusion
Cholesterol is not the enemy, but the structural material of every cell membrane. LDL cholesterol is not the only marker: ApoB and particle number reflect risk more accurately, while oxidation, inflammation, glycation, and a shift toward small dense subfractions amplify the harm of the particles.
Total cholesterol in 2026 is an outdated marker. Real vascular risk is reflected by ApoB, sdLDL, oxLDL, Lp(a), hsCRP and the omega-3 index. Treat the context, not the number. Restoring the endothelium, reducing oxidative burden, Mediterranean-type nutrition, and controlling insulin sensitivity stop atherosclerosis more reliably than chasing the “normal” total cholesterol range.

FAQ
My total cholesterol is 6.5 mmol/L — is this dangerous? Total cholesterol of 6.5 mmol/L by itself does not determine risk. You need ApoB, sdLDL, Lp(a), hsCRP, and the omega-3 index. If ApoB <80 mg/dL, sdLDL <25, Lp(a) <30, hsCRP <1, omega-3 >8% — real risk is low. If ApoB >100, sdLDL >35, Lp(a) >75, hsCRP >3 — risk is high, and total cholesterol is only the tip of the iceberg here.
ApoB or LDL — which is more accurate? ApoB. Each atherogenic particle (LDL, VLDL, Lp(a)) carries exactly one ApoB-100 protein. ApoB concentration = the number of atherogenic particles. LDL cholesterol reflects cholesterol mass, but not the number of particles. At the same LDL cholesterol level, a patient with a larger number of small particles (high ApoB) has substantially higher risk.
Should I take a statin if total cholesterol is 6.5 and ApoB is normal? Not necessarily. The decision requires an extended lipid panel, CAC-score, and assessment of 10-year risk (ASCVD calculator accounting for hsCRP and Lp(a)). With low ApoB, CAC = 0, and low hsCRP, primary prevention with a statin is rarely justified. The decision is always individual and made with a physician, not based on a single number.
Lp(a) is high — what should I do? Lp(a) is genetically determined and difficult to lower in isolation. Strategy: aggressive control of the other modifiable factors (ApoB <70, hsCRP <1, BP <120/80, HbA1c <5.4%, omega-3 >8%, smoking cessation). Niacin lowers Lp(a) by 20–30%, but tolerability is poor. Pelacarsen (an antisense oligonucleotide) is awaiting FDA approval and may potentially lower Lp(a) by 80%.
Which tests are enough to take once in a lifetime? Lp(a) — once in a lifetime, because it is genetically determined. Genetic testing for familial hypercholesterolemia (LDLR, APOB, PCSK9) — once if there is a family history. The other markers (ApoB, sdLDL, hsCRP, omega-3) — every 6–12 months during the active phase of the protocol, then annually for monitoring.
