Has Yu Canen Tang Warner Newton compound natto gout been eaten by people?

Yes, I come from Wuhan, and I also have gout. I went to Yu 'entang Yiguang to find out that Yu 'entang's recurrent natto was extracted by nine patented technologies and contained no purine. I ate compound natto for a month, about 15 days. The situation of gout has improved a lot. I hope my answer is helpful to you.
