Common Problems with Senna Extract in Supplement Formulation
When formulating with standard senna extract, manufacturers frequently encounter several recurring challenges.
- Poor water solubility in beverages or liquid formulas
- Dark precipitation after storage
- Inconsistent sennoside potency between batches
- Bitter taste profile difficult to mask
- High microbial counts from low-grade leaf material
- Limited documentation for EU / US imports
- Unstable actives under heat processing
