How to pronounce cholesterol in American English
kuh·LEH·stuh·rohl
Start here
Americans pronounce cholesterol as kuh-LEH-stuh-rohl (/kəˈlɛstəˌroʊl/). The L in "cholesterol" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, a hallmark of natural-sounding American speech. It comes out as kuh·LEH·stuh·ROHL. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "I have been monitoring my diet to manage my cholesterol levels".

uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
l/l/
Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.
eh/ɛ/
Drop your jaw moderately. Touch the tongue tip behind the bottom front teeth and lift the mid-front part slightly toward the roof.
s/s/
Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.
t/t/
Touch the tip or front edge of your tongue to the roof of your mouth just behind your teeth. Keep your jaw relaxed. Stop the air, then release with a puff.
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
r/r/
SyllabicThe schwa before R disappears — R becomes the vowel of the syllable. This is the 'er' sound without a distinct vowel before it.
oh/oʊ/
Start with your mouth slightly open, then close your jaw slightly as your lips round. Shift your tongue back slightly, then stretch the back up.
l/l/
DarkKeep the tongue tip down and pull the back of the tongue up toward the throat. The 'dark' sound comes from the back.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.

Treating every L the same.

cholesterol→kuh·LEH·stuh·ROHL
02
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch LEH — keep everything else short and quick.
KUH·leh·STUH·ROHL→kuh·LEH·stuh·ROHL
03
Pronouncing the first syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
KUH·LEH·stuh·rohl→kuh·LEH·stuh·ROHL
Questions
Questions people ask about this.
How is "cholesterol" stressed in American English?
Stress falls on the second syllable — say "LEH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "kuh-LEH-stuh-rohl" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the first syllable in "cholesterol" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "kuh-LEH-stuh-rohl" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "cholesterol" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "kuh-LEH-stuh-rohl" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
