Triglycerides

CardiovascularMeasured in mg/dL

What it measures

Circulating fat carried mainly in VLDL and chylomicron particles.

Why it matters

Elevated fasting triglycerides are among the earliest and cheapest signals of insulin resistance, typically appearing years before fasting glucose becomes abnormal.

Where the claimed ranges actually sit

Measured in mg/dL. Each row is one claim about where your result should fall.

Where the sources disagree

Almost all the disagreement here is about measurement conditions rather than biology. Triglycerides swing widely with recent food, alcohol, and illness. A platform that draws blood without confirming a genuine fast, then flags your result against a tight 'optimal' cutoff, is generating findings from noise. Ask what fasting state your draw assumed before you act on the number.

The marketed ranges, examined

Each claim gets its strongest possible case before it gets its criticism. Several of these are substantially correct.

Under 80 mg/dL

Promoted by metabolic health platforms and low-carbohydrate programs

The strongest case for it

Fasting triglycerides in the 80–150 range often reflect early insulin resistance well before glucose or HbA1c move, so a tighter target catches metabolic dysfunction earlier.

What it leaves out

The threshold is inferred from association studies rather than tested in trials, and triglycerides are the most volatile common lipid marker. A single meal, a drink, or a bad night's sleep moves them substantially.

Before you act on your result

Requires a genuine 10–12 hour fast for the standard interpretation.
Alcohol within 48 hours can substantially elevate results.
Very high values (above roughly 500 mg/dL) are a pancreatitis concern and need clinical attention, not optimization.
