Turmeric and boswellia supplements have gained popularity for their anti-inflammatory and antioxidant properties. It is important to critically assess the safety of such supplements for prolonged use. To assess the safety and tolerability of turmeric-boswellia-sesame oil formulation (TBSF) in healthy human volunteers. Forty participants were supplemented with TBSF at a dose of 2,000 mg daily for 90 days. Safety assessments were performed at baseline, as well as on day 30, 60 and 90. Adverse events were monitored throughout the study period. Any evidence of hepatotoxicity injury or drug induced liver injury (DILI) was assessed using R value (R ratio/R factor), which is a relative pattern of liver enzymes. Additionally, Hy's law criteria, based on liver enzymes and bilirubin levels, were employed, along with an evaluation of drug-induced serious hepatotoxicity (eDISH) plot. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were calculated, as these values are relevant to the safety of the intervention. The study found that TBSF supplementation did not cause any adverse effects or clinically significant variations in vital signs, hematological parameters, lipid profile, liver function enzymes, and renal function markers, and all were within the normal range after 90 days of TBSF supplementation. Platelet-to-lymphocyte ratio and NLR did not change significantly and were within the normal range. All the participants when plotted were in the normal range quadrant of the eDISH plot throughout the study period. No abnormal findings were observed in R value and Hy's law criteria, indicating that TBSF does not induce any hepatotoxicity. The present study showed a normal estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), creatinine (Cr), Cr clearance, and BUN/Cr ratio throughout the study period. There was no significant change between these values at 4 abovementioned time points. The study findings suggest that TBSF is a safe supplement for regular and long-term consumption.
