I do Omega 3 capsules from algae aswell, when i take b12, i knew that it takes some combination, also magnesium needs kalium to support it. I am well into the supplement stuff, but there is always something new to learn. I found a guy who runs a channel, who says iron supplement is actually bad because it accumulates over the years, and says it can be improved with blood letting. ( So giving some blood now and then is actually beneficial to your health.)
We have to be considerate with these supplements, too much can be a problem - to little and it might not have the intended effect.
But lets focus here in this thread on Taurine and Tinnitus - there are enough online information about other supplements. The tipp with B12 is for sure okay, wasnt aware that Prince did injections for that - but i dont know Elvis was killed by his doctor some people say.
Just for the sake of it - i googled it, and pub.med didnt have any beneficial reports for singing actors reportet.
Nevertheless the rat experiment is confirmed by pub.med. I am for sure no doctor, so make up your own mind, and inform yourself.
