A recent peer-reviewed study in Integrative Food, Nutrition and Metabolism (2025) confirms the performance advantages of plant-based minerals over synthetic forms. Star Hi’s patented ingredients, STORG-I (organic curry leaf iron) and STORG-ZN (organic guava zinc), demonstrated higher absorption, strong antioxidant potential, and measurable immune-support benefits, reinforcing the growing value of organic, plant-sourced minerals in clean-label formulations.
Bioavailable Nutrition, Backed by Science
STORG-I and STORG-ZN are derived from nutrient-rich botanical sources—curry leaf (Murraya koenigii) and guava leaf (Psidium guajava)—that naturally bind minerals to polyphenols, flavonoids, and organic acids. This plant-based matrix improves intestinal uptake and utilization in ways that isolated synthetic minerals cannot replicate.
In comparative testing, STORG-I reached a peak plasma concentration of 197.3 µg/mL versus 172 µg/mL for synthetic iron, while STORG-ZN achieved 298 µg/mL versus 270 µg/mL for synthetic zinc. Both maintained steady absorption over time, confirming efficient bioavailability and consistent delivery. The results suggest that the plant’s natural cofactors enhance mineral transport while contributing additional antioxidant support.
Natural Support for Immunity and Recovery
Beyond absorption, both ingredients demonstrated measurable immunomodulatory effects. Animals supplemented with STORG minerals showed higher antibody production and improved hematological parameters following immune suppression. STORG-ZN, in particular, enhanced lymphocyte function and humoral immunity, demonstrating its dual role as a mineral source and immune modulator. The inclusion of guava’s native flavonoids may further contribute to immune resilience and oxidative defense.
Gentle, Clean, and Consumer-Ready
Formulators seeking alternatives to synthetic salts often struggle to balance efficacy with digestive comfort. STORG-I provides effective iron supplementation without the gastrointestinal irritation commonly linked to ferrous sulfate. STORG-ZN adds further value through guava’s natural antioxidants, offering broad support for immune, metabolic, and skin health applications.
Both ingredients are USDA Organic certified, non-GMO, and suitable for clean-label and vegan formulations. With strong scientific validation and growing consumer demand for plant-based nutrition, STORG-I and STORG-ZN set a new standard for mineral supplementation— natural, effective, and clinically supported.
