The short answer

Ask five questions.

1. Was it tested in humans, or in mice and dishes?

2. Was it a randomized trial, or a story?

3. Did it measure something that matters, such as heart attacks or strength, or only a lab number?

4. How many people, and for how long?

5. Who profits if I believe it?

A confident voice, a white coat, and a large audience are not evidence. Neither is a list of references under a video. Be especially careful with anyone who is never uncertain.
