Background and objective: Oxidative stress is a common factor for various diseases like cancer, diabetes, metabolic disorders, atherosclerosis, and cardiovascular diseases. The incidence of such diseases is growing day by day around the globe and causes various complications. The disease not only affects the quality of life but also the mortality rate with this disease is too high. Considering these factors, it is important to come up with a simple yet potential solution for reducing oxidative stress. Therefore, RV New Visions Health Care Pvt. Ltd has developed an RV forte capsule as a potential treatment for reducing oxidative stress and help to fight against cancer. Materials and Methods: Antioxidant activity of RV forte capsule was evaluated In-vitro by using DPPH scavenging assay, H2O2 radical scavenging assay, and Reducing power assay. Further, toxicity testing in animal models and the standardization using the HPTLC method was done. Results: The formulation RV forte capsule showed significant anti-oxidant action when compared with standard ascorbic acid. The percentage scavenging activity of RV forte capsule was found to be 14.2 - 60.05 % at 50 - 500 ug/ml by DPPH scavenging assay,17.57 – 55.27 % by hydrogen radical scavenging assay, and the reducing power was found to be increasing with increased absorbance at 50-500 ug/ml concentrations. In toxicity testing, no toxicity was found at the dose of 100mg/kg. Conclusion: The study thus proves, RV forte capsule has significant antioxidant activity
