High Cholesterol Support

Reviewed by the Nimbera editorial team · Last updated May 2026

High cholesterol refers to elevated levels of LDL (low-density lipoprotein) cholesterol or total cholesterol in the blood, increasing the risk of heart disease and stroke. Lifestyle changes and certain evidence-backed supplements can meaningfully reduce cholesterol levels alongside medical treatment.

When to see a doctor

See a doctor if you have a family history of early heart disease, have been diagnosed with high cholesterol, experience chest pain or shortness of breath, or if lifestyle changes have not improved your levels after 3-6 months.
