What is a good ApoB level?

ApoB apob cholesterol heart-health

By Arun AgrahriLast reviewed 1 timecoded source

Short answer

Lower than most labs flag as normal. Studies Precis has read agree that heart risk keeps rising as ApoB climbs. Targets on tape run from under 90, ideally under 70 mg/dL, to a ceiling of 60. One study in high blood pressure found the lowest death risk near 100 mg/dL.

Detailed Answer

A good ApoB level is lower than the lab's normal flag, by the studies Precis has read. There is no one universal number, but the direction is clear. ApoB counts the particles that build plaque (LDL, VLDL and Lp(a)) instead of the cholesterol they carry. That gives a fuller picture of heart risk than LDL-C.

What the verdict rests on

Seven credited sources count: five studies and two researchers on tape. Six back the claim and one does not. A genetic study, using Mendelian randomization (a method that uses inherited gene variants to test cause), found that risk of coronary artery disease and death kept climbing as ApoB rose.

A UK Biobank study of people with type 2 diabetes found heart risk rising in a roughly straight line with ApoB. A pooled analysis of trials of the drug alirocumab linked lower achieved ApoB to fewer major heart events. After a heart attack or unstable angina, the drug's benefit grew as achieved ApoB fell.

The targets on tape

Peter Attia, on his own show, treats an ApoB of 60 as the ceiling, which he places at about the fifth percentile. He would go further and lower ApoB with drugs to 20 to 30 mg/dL for everybody. He points to children, who run about 20-40 mg/dL, as the benchmark, and works to about 60 mg/dL for people in their late 30s and early 40s.

Mark Hyman, a guest on Rangan Chatterjee's show, says under 90 but ideally under 70. On his own show, he puts the likely optimal range at 40 to 70.

Where the evidence parts ways

One study pushes back. In people with high blood pressure, the link between ApoB and death was U-shaped, with the lowest risk around 100 mg/dL. Few studies Precis has read set a lab's normal range against outcomes directly. The case rests on risk rising inside that range. Another 12 studies on this claim wait for a full read before they count.

What to ask for

ApoB is often missing from a basic cholesterol panel, so ask for it with advanced lipid testing. A normal LDL can hide a high particle count. Hitting a low target usually takes diet plus medication under a doctor's care, such as statins, ezetimibe, bempedoic acid or PCSK9 inhibitors. Your target, and whether to add a drug, is your physician's call.

Related Questions

What ApoB level is optimal?
Lower than most labs flag as normal. Targets on tape run from under 90, ideally under 70 mg/dL, down to a ceiling of 60 mg/dL, with childhood levels of about 20-40 mg/dL as a benchmark. Targets are individual and set with a physician.
Is ApoB better than LDL cholesterol?
On the record, yes. ApoB counts the particles that build plaque instead of estimating cholesterol mass. After a heart attack or unstable angina, one trial analysis found benefit grew with lower achieved ApoB at every LDL-C level.
Can a normal LDL still mean high ApoB?
Yes. Many heart-attack victims have normal LDL. Measuring ApoB alongside a standard panel catches that.
Can ApoB be too low?
One study of people with high blood pressure found a U-shaped link with death, with the lowest risk around 100 mg/dL. The other studies Precis has read found risk rising with ApoB. Ask your physician where your target should sit.
