Isabgol (psyllium) is India's default fibre. PHGG is what most people should probably be taking instead. Here's the honest comparison.
Psyllium works — it's well studied for regularity. But it thickens instantly into a gel most people can't stand drinking, it can cause gas and bloating early on, and compliance collapses within weeks. A fibre you quit is a fibre that doesn't work.
Fibre only works daily. That's why SILT Mornings uses PHGG at the full 5 g clinical dose inside a Lemon Orange morning drink you'd actually look forward to — the fibre disappears into the ritual instead of fighting it.
