Taurine

Is taurine from Chinese company qianjiang yongan pharmaceutical is good? I found some mentions of this taurine on fda.gov website.

Some resellers offer 1 kg of this taurine just for 38 USD

I’m taking 6 grams per day and give 5 grams per day to my cat. so it’s really annoying to buy countless bottles with pills that last just for 2-10 days.
