I’ve been taking psyllium husk powder capsules for 3 weeks now. I first bought the Wal-Mucil brand from Walgreens, and took 3g/day (6 capsules). That worked great. My stool went from about a 4.5 to a 3.5 on the Bristol stool scale, and instead of multiple bowel movements a day, it became once or twice a day.
After that ran out I started taking the NOW brand. I took 3g/day, but that wasn’t very effective so I started taking 4g/day. I’ve been taking 4g/day for 2 days now and my bowel movements still haven’t been the same as with Wal-Mucil. I’ve had significant gas, and trips to the toilet multiple times a day, sometimes with strong urge to go that ends up being sharting-like when I do go.
I came across this review on Amazon, which explains that NOW uses Plantago asiatica, while it seems that most other brands use Plantago ovata. For most other brands (including Wal-Mucil), the label just says “Psyllium Husk”, “Psyllium Husk Seed”, or “Psyllium Husk Fiber” under ingredients; it does not specify a species. Wikipedia article for Psyllium seed husks defines them as “portions of the seeds of the plant Plantago ovata”. The article for Plantago asiatica says nothing about psyllium seed husks.
I am going to go cold turkey off of the NOW capsules and see what happens. If that doesn’t work, I will experiment with different doses of NOW. If that fails, I guess I will have to buy Wal-Mucil or a different brand. I will update this thread with the results.
Has anyone else had similar or relevant experiences? @livingparadox I know you use psyllium husk
Update 5/30/15 - So I gave up on the NOW capsules and went back to the Wal-Mucil capsules. I take 6 capsules/day, which is 3g of psyllium husk.
