I never know some supplements can increase gray hair. I've been taking vit C, collagen, glutathion and bunch of other stuff for skin on and off since 28 y old. I'm 37 soon 38 y old. Hopefully gray hair not showing up anything soon. Your comment is really helpful as I don't understand japanese but there are translation options for the comment. Arigato🌸
every person’s body is unique,it really depends on how one’s body take the side effects, transino white for me,never had an upset stomach,unlike the vitamin c, i had sores😢
