Fortified food and dietary supplement products may be administered to produce desirable physiological improvement. In particular, embodiments of the invention relates to the administration of products enhanced with plant products and iridoids. A study was performed to evaluate the iridoid content, as well as the in vitro and in vivo bioactivities, of a beverage containing noni fruit, Cornelian cherries, and olive leaf extract. The major iridoids present were identified as asperulosidic acid, deacetylasperulosidic acid, oleuropein, morroniside, loganic acid, and loganin In the 2,2-Diphenylpicrylhydrazyl (DPPH) radical scavenging assay, remarkably high in vitro antioxidant activity was observed, with an IC.sub.50 of 3.8 .mu.L/mL. In vivo bioactivities were evaluated in type 2 diabetic Sprague Dawley rats. In a dose-dependent manner, the composition reduced abnormal weight gain, blood glucose levels, and serum advanced glycation end products (AGEs), as well as improved immunity via increased T cell counts and CD4+/CD8.sup.+ ratios.
