I don't know if coffee is OK or not.

I usually have the Taurine+water first thing. Then I go about a few morning tasks, brush teeth, etc, and then have a cup of green tea followed by a cup of black tea.

I drink coffee later in the day.

But that's just me.

I found this:

It seems Taurine might diminish the effects of caffeine, but they are talking energy drink doses of caffeine.

I generally trust the National Institute of Health, pubmed site more than others. Since it's peer-reviewed in scientific journals, it's open to scrutiny by other scientists. That doesn't mean the author does not have an agenda, but it lessens it.

open pubmed and put taurine in the search box and there are plenty of articles written about it.

I do hope this works for you. Remember, it works gradually, and you won't know for a couple of months.

Over the years my tinnitus had diminished at least 90% and I have many quiet days, when before taurine, I had none.

If it works for you, I'll be happy for you.
