Regarding Mercola.
He is widely regarded as dangerously and intentionally misleading by a variety of reliable sources, including many from outside the media. Here are just two:
Boston University:
Research: Fake News and News Bias: Fact checking links
Monmouth College:
Hewes Library: Evaluating Information Sources: Resources
Additionally, he has a laundry list of specific examples, including:
- He says that there is a specific risk to those who take the Covid vaccine, when that risk does not exist:
Post makes false claim about COVID-19 vaccine risk
- That seniors dying from the Covid vaccine are having their COD listed as natural causes, which they are not:

(This is a registration-needed archive site, reprinting an article that was once on his website.)
- He insisted that a variety of products that he conveniently sells in his shop could cure Covid, when they couldn't. Here is the FDA warning letter:

- On the non-Covid front, he said a heat detector can catch breast cancer more safely than a mammogram, which is dangerously wrong:
FDA warns doctor: Stop touting camera as disease screening tool
There are a lot more.
In poking around while writing this post, I also found this paragraph in an article from Quackwatch:
Many of Mercola’s articles make unsubstantiated claims and clash with those of leading medical and public health organizations. For example, he opposes immunization [11] fluoridation. [12], mammography [13], and the
routine administration of vitamin K shots to the newborn [14,15]; claims that amalgam fillings are toxic [16]; and makes many unsubstantiated recommendations for dietary supplements. He has advised against eating many foods that the scientific community regards as healthful, such as bananas, oranges, red potatoes, white potatoes, all milk products, and almost all grains [17]. He has also given silly advice, such as minimizing exposure to electromagnetic fields by avoiding electric razors, microwaving of foods, watches with batteries [18]. Mercola’s reach has been greatly boosted by repeated promotion on the “Dr. Oz Show.”

Personally, that alone would convince me to avoid his advice.
