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.

The present invention relates to a browning-inhibiting composition containing a compound represented by the following formula (1): ##STR00001##
wherein R.sup.21, R.sup.22, R.sup.23, R.sup.24, R.sup.26 and R.sup.27 each independently represent a hydrogen atom or a substituent, and at least one of R.sup.21 or R.sup.23 is a hydrogen atom; when R.sup.23 represents a hydrogen atom, at least one of R.sup.22 or R.sup.24 represents a substituent; R.sup.25 represents a hydrogen atom, an oxygen atom, or a substituent; R.sup.22 and R.sup.23, or R.sup.23 and R.sup.24 may be bonded together to form a ring with an oxygen atom and a carbon atom to which these Rs are bonded; R.sup.25 and R.sup.26, or R.sup.26 and R.sup.27 may be bonded together to form a ring structure with carbon atoms to which these Rs are bonded; X represents an oxygen atom or —CH.sub.2—; and a dashed line may represent a double bond.

The present invention addresses the problem of providing an edible oil and fat that is usable for any kind of food, has an improved oxidation stability, and exhibits a good flavor. By stably dispersing a tea extract together with an acid in an oil and fat, the oxidation stability can be improved without increasing the formulation amount of the tea extract.
