LDL cholesterol of 175: what it means and how to lower it

Ranked by an overall score that blends how much of your gap the lever could close, how doable it is, how strong the evidence is, and how accessible it is. Effects are population averages and are partly overlapping — this is a menu, not a checklist to do all at once.

1. 1

   Cut saturated fat, replace with unsaturated

   Diet

   ~9%

   typical LDL cholesterol drop

   Evidence A

   The swap matters: replace butter/red meat with olive oil, nuts and fish — replacing it with refined carbs undoes the LDL benefit.

   Source: Hooper 2020 (Cochrane) · 15 RCTs, 56,675 participants: cutting saturated fat for at least two years reduced combined cardiovascular events by 17% (RR 0.83, 95% CI 0.70–0.98), with greater reductions in saturated fat producing greater reductions in events.

2. 2

   Plant sterols / stanols (2 g/day)

   Supplement

   ~9%

   typical LDL cholesterol drop

   Evidence A

   Benefit plateaus above ~2–3 g/day. Works through a different mechanism than fiber, so it adds a bit on top of it.

   Source: Ras 2014 (Br J Nutr) · 124 studies: plant sterol/stanol intakes of 0.6–3.3 g/day lowered LDL by 6–12%, with the effect rising up to about 3 g/day and then plateauing.

3. 3

   Viscous fiber — psyllium (~10 g/day)

   Fiber

   ~7%

   typical LDL cholesterol drop

   Evidence A

   Fiber levers are sub-additive — stacking psyllium, oats and beans won't simply add up. Build up the dose slowly to avoid bloating.

   Source: Jovanovski 2018 (Am J Clin Nutr) · 28 RCTs, 1,924 participants: a median 10.2 g/day of psyllium lowered LDL by 0.33 mmol/L (~13 mg/dL), non-HDL by 0.39 mmol/L and apolipoprotein B by 0.05 g/L.

4. 4

   Oat beta-glucan (~3 g/day)

   Fiber

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Counts toward the same viscous-fiber effect as psyllium, not on top of it. ~3 g beta-glucan ≈ a bowl and a half of oats.

   Source: Whitehead 2014 (Am J Clin Nutr) · 28 RCTs: at least 3 g/day of oat beta-glucan lowered LDL by 0.25 mmol/L (~10 mg/dL) and total cholesterol by 0.30 mmol/L, with no significant effect on HDL or triglycerides.

5. 5

   Bergamot polyphenol supplement

   Supplement

   ~15%

   typical LDL cholesterol drop

   Evidence C

   Promising but the evidence is low-quality and short-term. Not a statin substitute; quality varies between brands.

   Source: Lamiquiz-Moneo 2020 (Crit Rev Food Sci Nutr) · 12 human studies: 75% showed a significant LDL reduction, ranging 7.6% to 40.8% — but the authors note the designs were heterogeneous and the scientific quality of the studies was 'quite limited'.

6. 6

   Regular aerobic exercise

   Lifestyle

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Genuinely lowers LDL, but modestly — pooled across 148 trials it is about 5%, alongside a similar drop in triglycerides. Do it for your overall cardiovascular risk; it will not close a large ApoB gap on its own.

   Source: Smart 2025 (Sports Med) · 148 RCTs, 8,673 participants: exercise training lowered LDL by 7.22 mg/dL (95% CI −9.08 to −5.35) and triglycerides by 8.01 mg/dL (95% CI −10.45 to −5.58) — 'significant but modest' 3.5–11.7% improvements. Trial sequence analysis found the evidence base has reached futility, meaning further trials are unlikely to overturn it.

7. 7

   Tree nuts / almonds (~45 g/day)

   Diet

   ~4%

   typical LDL cholesterol drop

   Evidence B

   Modest on its own. Best as a replacement for refined snacks, not added on top of your current calories.

   Source: Del Gobbo 2015 (Am J Clin Nutr) · 61 controlled trials, 2,582 participants: each 28.4 g/day serving lowered LDL by 4.8 mg/dL, apolipoprotein B by 3.7 mg/dL and triglycerides by 2.2 mg/dL.

8. 8

   Lose 5–10% of body weight (if overweight)

   Lifestyle

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Bigger effect on ApoB and triglycerides than on LDL, and the hardest lever to sustain — but it improves many risk factors at once.

   Source: Hasan 2020 (J Clin Endocrinol Metab) · 73 RCTs, 32,496 adults: each kilogram lost lowered triglycerides by 4.0 mg/dL and LDL by 1.28 mg/dL at 12 months. The review did not measure apolipoprotein B.

9. 9

   Cut refined carbs & added sugar

   Diet

   ~3%

   typical LDL cholesterol drop

   Evidence B

   Lowers triglycerides and, by a few percent, LDL — and not just by way of weight loss. What replaces the carbs still matters: swapping them for saturated fat can push LDL back up.

   Source: Te Morenga 2014 (Am J Clin Nutr) · 37 lipid trials: higher versus lower free-sugar intake raised triglycerides by 0.11 mmol/L and LDL by 0.12 mmol/L (P = 0.0001). The relation was strongest in trials that held energy intake constant, and the authors conclude it is independent of any effect of sugar on body weight.

10. 10

    Soy protein (~25 g/day)

    Diet

    ~4%

    typical LDL cholesterol drop

    Evidence B

    Small, well-tolerated effect — most useful when soy displaces animal protein and its saturated fat.

    Source: Blanco Mejia 2019 (J Nutr) · 43 trials identified by the FDA: a median 25 g/day of soy protein lowered LDL by 4.76 mg/dL, about 3–4%, versus non-soy protein controls.

Surfaced because the gap is larger than lifestyle changes can plausibly close. Apolane does not prescribe — these are conversation starters for a visit with a clinician, ranked the same way.

1. 1

   Statin — high intensity

   Prescription (oral)

   ~50%

   typical LDL cholesterol drop

   Evidence ADiscuss with your doctor — we don't prescribe

   The strongest single oral agent (e.g. rosuvastatin 20–40 mg, atorvastatin 40–80 mg). Larger LDL/ApoB drop, slightly higher rate of side effects.

   Source: AHA/ACC 2018 Cholesterol Guideline · The guideline defines high-intensity statin therapy — for example atorvastatin 40–80 mg or rosuvastatin 20–40 mg — as lowering LDL by 50% or more on average.

2. 2

   Statin + ezetimibe (combination)

   Prescription (oral)

   ~60%

   typical LDL cholesterol drop

   Evidence ADiscuss with your doctor — we don't prescribe

   Stacking two mechanisms gets most people to goal with generic, oral, low-cost drugs before injectables are needed.

   Source: IMPROVE-IT 2015 (N Engl J Med) · 18,144 patients after acute coronary syndrome: adding ezetimibe to simvastatin 40 mg lowered time-weighted mean LDL from 69.5 to 53.7 mg/dL and reduced the primary composite endpoint (32.7% vs 34.7%, HR 0.936, P = 0.016).

3. 3

   Statin — moderate intensity

   Prescription (oral)

   ~35%

   typical LDL cholesterol drop

   Evidence ADiscuss with your doctor — we don't prescribe

   First-line, cheap, and the most evidence of any lipid drug. About 5–10% of people report muscle symptoms; often manageable by switching agent or dose.

   Source: AHA/ACC 2018 Cholesterol Guideline · The guideline defines moderate-intensity statin therapy as lowering LDL by 30–49% on average, noting that these percentages are estimates across large populations and that individual response varies.

4. 4

   Bempedoic acid + ezetimibe (combination)

   Prescription (oral)

   ~38%

   typical LDL cholesterol drop

   Evidence ADiscuss with your doctor — we don't prescribe

   A muscle-sparing oral combination — a strong statin-free option for statin-intolerant people who need more than one lever.

   Source: Ballantyne 2020 (Eur J Prev Cardiol) · 301 patients already on maximally tolerated statin therapy: the bempedoic acid 180 mg + ezetimibe 10 mg fixed-dose combination lowered LDL by 36.2%, against 23.2% for ezetimibe alone and 17.2% for bempedoic acid alone.
