In the US legal system something or some act is considered legal until a law makes it illegal. They’re selling a good as food so it’d come under whatever regulations are in place for food. Their products don’t contain any ingredients requiring any other regulation. There’s maybe some approval process to show that what they say is in the product is actually there through some regulation somewhere, but they’re not like certifying a drug with drug trials.
