Formulation, Phytochemical Characterization, and Clinical Assessment of a Novel Natural Supplement Targeting Body Composition in Physically Active Individuals

This randomized, double-blind, placebo-controlled clinical trial assessed the efficacy of a novel, multi-ingredient natural supplement (NNS) designed to improve body composition and metabolic health in endurance-trained individuals. The NNS formulation combines plant-based proteins, dietary fibers, polyphenols, and antioxidant-rich botanicals with the aim of enhancing lean mass, reducing body fat, and supporting cardiopulmonary function. The active ingredients include whey protein, pea protein, oats, sweet potato, flaxseed, chia seeds, spinach powder, cardamom, green tea extract, beetroot powder, and stevia.

Prior to clinical assessment, the formulation underwent detailed chemical characterization, including analysis of physicochemical properties (pH, acidity, °Brix), proximate composition (fat and protein content), mineral profile (via ICP-OES), fatty acid composition (via GC-FID), antioxidant capacity (DPPH and ABTS assays), and bioactive compound identification (GC-MS). The formulation demonstrated high protein content, a favorable fatty acid profile rich in omega-3s, potent antioxidant activity, and the presence of bioactive compounds with anti-inflammatory and muscle-supportive properties.

In the clinical phase, participants were randomly assigned to consume either the NNS or a placebo (matched in appearance, flavor, and texture) daily for 8 weeks. Blinding was maintained for participants, care providers, investigators, and outcome assessors. Body composition was assessed via bioelectrical impedance analysis, alongside measurements of oxygen saturation, heart rate, and serum metabolic markers. The study aimed to provide scientific validation for the role of natural, protein-rich, multi-ingredient supplements in promoting muscle accretion, reducing body weight and BMI, improving metabolic markers, and supporting cardiopulmonary health in physically active individuals
