Low Density Lipoprotein (LDL) cholesterol is the amount of cholesterol within LDL particles (proteins that carry hydrophobic molecules through extracellular fluid). It is seen as the 'bad' cholesterol, as it's a risk factor for atherosclerosis, and much of atherosclerotic plaque is made up of LDL, though it's unclear if higher LDL-C is always worse. LDL serves to bring fatty acids and cholesterol from the liver and circulate them to tissues, oxidized LDL (oxLDL) in particular seems to contribute to heart disease.

| Grade | Level of Evidence [show legend] |
|---|---|
|
Robust research conducted with repeated double-blind clinical trials |
|
Multiple studies where at least two are double-blind and placebo controlled |
|
Single double-blind study or multiple cohort studies |
|
Uncontrolled or observational studies only |
|
Level of Evidence
?
The amount of high quality evidence. The more
evidence, the more we can trust the results.
|
Supplement |
Magnitude of effect
?
The direction and size of the supplement's impact on
each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
|
Consistency of research results
?
Scientific research does not always agree. HIGH or
VERY HIGH means that most of the scientific research agrees.

There appears to be a reliable and significant reduction in circulating LDL cholesterol in hypercholesterolemic persons with garlic supplementation, and the magnitude of this change tends to be in the range of 10-20% (more potency in those with worse profiles at baseline)

Cocoa products appear to be able to reduce LDL cholesterol due to their flavonoid component, with the reduction in LDL-C being mild.

A decrease has been noted in persons without high cholesterol in the first place, and the decreasing effect of statins appears to be augmented with fish oil. However, in persons at higher risk for cardiovascular disease due to high triglycerides and cholesterol (who more frequently use fish oil as therapy) it is possible LDL-C may actually be increased. The magnitude tends to be in the 5-10% range.
