A human dietary supplement comprises theacrine and optionally other compounds that modulate the effects of theacrine. Uses for the theacrine-containing supplement include improvement of at least one of mood, energy, focus, concentration or sexual desire or a reduction of at least one of anxiety or fatigue. A synergistic composition comprises co-administration of theacrine and caffeine, wherein the co-administered caffeine reduces theacrine oral clearance (CL/F) and oral volume of distribution (Vd/F). In addition, the co-administered caffeine increases area under the plasma concentration time curve (AUC) of theacrine, and increases theacrine maximum plasma concentration (C.sub.max) in comparison with the corresponding pharmacokinetic parameters when theacrine is administered alone.

A nutritional or dietary supplement composition useful for formulating meal replacements, particularly beverage-based meal replacements. The composition is absorbed well in patients with compromised gastrointestinal absorption status, such as those having undergone bariatric surgery, other gastrointestinal surgery, those undergoing chemotherapy, and those with other gastrointestinal absorption disorders. Moreover, the compositions are nutritious foods for healthy people. Lastly, the compositions are useful for people with insulin disorders, difficulty maintaining healthy body weight, or inflammation-related disorders. Related methods are also provided.
