Psyllium husk is a natural soluble fibre commonly used to support digestive health, regularity, and fibre intake. It comes from the outer husk of the Plantago ovata seed and is often used in homemade supplements, wellness capsules, and fibre blends.
Because psyllium husk powder is very light and fluffy, it takes up more space inside capsules compared to denser powders like caffeine or creatine. This means larger capsule sizes are usually the best option.
For most people, size 000 capsules are the best capsule size for psyllium husk powder.
What Is Psyllium Husk?
Psyllium husk is a plant-based fibre supplement made from the husks of psyllium seeds.
It is commonly used for:
- Digestive support
- Increasing daily fibre intake
- Supporting regular bowel movements
- Wellness and gut health routines
