The global demand for herbal and plant-based health supplements continues to grow. With it comes increasing pressure on manufacturers to deliver clean-label, high-dose, and consumer-friendly tablets—without compromising efficiency or product quality.
However, formulating herbal tablets is far from straightforward.
Herbal extracts often show high variability due to differences in species, origin, and harvesting conditions. Many are fibrous, hygroscopic, or lack sufficient binding properties, leading to poor flow, inconsistent tablet weight, and fragile tablets. Wet granulation can improve flow, but moisture sensitivity, microbial risk, and regulatory restrictions on excipients make this approach unsuitable for many herbal actives.
The Challenge
In addition to processability issues, herbal formulations frequently require:
- High active loads, resulting in large or hard-to-swallow tablets
- Good hardness and low friability for bottle packaging
- Effective taste masking and appealing appearance
- Limited excipient choices, especially for “natural” or “health functional food” products
Achieving all this with minimal processing steps is a significant formulation challenge.
The Solution: BonuTab® for Direct Compression
BIOGRUND’s BonuTab® is a fully formulated, ready-to-use tableting system designed specifically to address these challenges. By leveraging synergistic excipient combinations, BonuTab® enables reliable direct compression, eliminating the need for wet granulation.
In this case study, a green tea extract tablet was successfully produced using a customized BonuTab® formulation:
- 67% green tea extract
- 33% BonuTab® premix
The result was a robust tablet with:
- Excellent flow properties
- High breaking force (>300 N)
- Low friability (<0.5%)
- Consistent appearance and improved taste masking
All achieved through direct compression, improving production efficiency and reducing development time.
Why It Matters
BonuTab® helps manufacturers bring herbal supplements to market faster while ensuring batch-to-batch consistency, scalability, and clean-label flexibility—even for high-dose formulations.
