Delivery System Constraints & Modeling

Every active compound behaves uniquely based on the physical matrix it is suspended in. Below are the known physical chemistry challenges for L-Citrulline across standard consumer modalities.

💊 Standard Capsules

The high hygroscopicity of L-Citrulline requires moisture-resistant HPMC capsules and desiccant inclusion to prevent clumping and degradation.

🍬 Gummy & Pectin Formats

Achieving therapeutic dosages in a gummy format is physically challenging due to the high active-to-excipient ratio required, which compromises structural integrity and texture.

🔬 Thin-Film Oral Strips

The significant payload requirement for L-Citrulline far exceeds the typical 50-100mg capacity of thin-film oral strips, making this delivery method impractical for clinical efficacy.
