Monteloeder, a subsidiary of SuanNutra, has published clinical study results backing its natural, beauty-from-within formulation Nutroxsun. The two-phase trial supports Nutroxsun’s role in helping maintain the skin’s collagen integrity and visible radiance when exposed to environmental stressors such as ultraviolet (UV) radiation. Nutroxsun is a proprietary combination of extracts of rosemary (Rosmarinus officinalis) and grapefruit (Citrus paradise). It will be presented at Vitafoods Europe, Barcelona, Spain (May 20–22, 2025).
