Taking Psyllium Husk While Intermittent Fasting

Incorporating Psyllium Husk into your intermittent fasting routine can be an effective way to help curb hunger and make fasting less challenging. It’s important, however, to take it at the right time for optimal results.

During a 16-8 or 18-6 intermittent fast, you should take your Psyllium husk powder around 7 pm in the evening, which is just before dinner.
