Tinospora cordifolia (TC) and &lt;em&gt;Azadirachta indica&lt;/em&gt; (AI) are traditional medicinal plants that has been used for diabetes since ancient times, but their combined potential as a formulation has not been evaluated for the management of diabetes. &lt;strong&gt;Objectives:&lt;/strong&gt; This study aimed to profile the phytochemical composition of 70% hydroethanolic extracts of TC and AI, assess their antioxidant and antidiabetic activity individually and in combination, and further substantiate their efficacy through in-silico molecular docking and ADMET evaluation of their key bioactive compounds, berberine and nimbolide. &lt;strong&gt;Methods: &lt;/strong&gt;Hydroethanolic extracts of TC and AI were subjected to preliminary phytochemical screening, quantification of primary and secondary metabolites, and HPTLC profiling. Five combinations of TC:AI (1:1, 1:2, 2:1, 1:3, 3:1) were prepared and evaluated for antioxidant activity using DPPH, ABTS, and FRAP assays, and for antidiabetic potential using α-amylase, α-glucosidase, and PTP1B inhibition assays. IC&lt;sub&gt;₅₀&lt;/sub&gt; values were calculated. &lt;em&gt;In-silico&lt;/em&gt; studies were performed for berberine and nimbolide using AutoDock 4.2.6 against PPARγ, GLUT4, and IRS1. Drug-likeness and ADMET properties were predicted using SwissADME and pkCSM. &lt;strong&gt;Results:&lt;/strong&gt; Phytochemical profiling confirmed the presence of alkaloids, polyphenols, flavonoids, and tannins. TC demonstrated stronger inherent antioxidant and antidiabetic activity than AI. Among combinations, 1:1 and 3:1 formulations showed the highest potency with IC₅₀ values comparable to standards. Molecular docking revealed strong binding affinities of berberine and nimbolide toward PPARγ, GLUT4, and IRS1, while ADMET prediction indicated acceptable pharmacokinetic behaviour and good drug-likeness. &lt;strong&gt;Conclusion:&lt;/strong&gt; The TC:AI 1:1 formulation exhibited synergistic antioxidant and antidiabetic effects, supported by favorable &lt;em&gt;in-silico&lt;/em&gt; interactions and pharmacokinetic profiles, highlighting its potential as a natural therapeutic option for T2DM management.&lt;/p&gt;
