I have seen videos of people asking to drink isabgol for fiber intake . I am suffering from indigestion and bloating since few weeks. And my daily fiber intake is poor. According to science is there any good fiber supplement that is safe to drink ? When should one drink it get best benefits ? Some supplements come with pre and pro biotics added ? Is that good ? Also there are some warning like to drink good amount of water or else death can occur. So I am afraid what to do ? Soluble and insoluble fiber is crucial right ? So what to eat ? When ? How much daily ? I live in India. Everything as per science backed evidence
