Healthline Media, Inc. is an American website and provider of health information headquartered in San Francisco, California.

[5] A 2020 study of readability ranked Healthline the second hardest to read (highest education level required) among the top five Google search results for "phenylketonuria", excluding Wikipedia.

For example, the site Health News Review said a Healthline article about a new medication used promotional language copied from the drug-maker's press release, neglected to cite side effects, and framed the drug's claimed benefits in misleading language that failed to accurately reflect the evidence in a peer-reviewed medical journal.

[16] In a study using coverage of neck pain to evaluate a tool designed to review health websites, researchers from the University of Brighton gave Healthline a score of "good".

A study of top-ranking health websites published in 2021 evaluated its quality as "good", lower than MedlinePlus's "excellent" scores but higher than affiliate Medical News Today's "fair/good" ranking.
