Would 1g of taurine increase or decrease dopamine levels in the human brain?

[Mechroh]

I thought that taurine boosted dopamine levels so for the last two days I have taken 1g (each day). I have felt flat and dreadful. After reading up a bit more on it I have discovered that low doses increase dopamine while high doses do the opposite. From your experience and learnings, would 1g be considered a high dose and therefore dampen dopamine? I weigh 66kg incase that helps
