I did some light research and asked AI, which said it would be extremely dangerous. But come on, it wouldn’t be that dangerous, right? We evolved from animals that lived in the ocean.

does the immune system nullify risk of contracting an illness in other contexts? Certainly not perfectly - and injecting dirty sea water directly puts the bacteria, fungi, and parasites into your bloodstream, bypassing the protective measures your body normally has for keeping that stuff on the outside (like mucus, hair, the acidic environment of the stomach, etc.).
Yeah, you might be able to make ghetto saline with distilled water and the ocean and not become emergently ill, but you shouldn’t actually do it. Even if you collect from an immaculate site and dodge any human (or mammal? This is the kind of weird situation where zoonosis could happen) pathogens, foreign bodies in the bloodstream won’t make you healthier.
I haven’t seen much evidence OP thinks this is a good idea and not just a thought experiment, though. That would be weird.
I wouldn’t want to do that without some significant heat and pressure for an extended period of time, and maybe without some preservatives added for good measure, and honestly I wouldn’t be past using a syringe filter to further purify it - anything that gets injected into my body better be safe, those are crazy risks
