Provided herein are compositions (e.g., pharmaceutical compositions, nutraceutical compositions, foods, beverages, cosmetic compositions, diet supplements) comprising deuterated caffeine. The provided compositions may be useful for treating and/or preventing various diseases and conditions, such as obesity, causing weight loss, increasing metabolic rate, reducing appetite, increasing energy expenditure, increasing urine output, increasing sodium excretion, reducing edema, a pain disorder, apnea, hypotension, an encephalopathy, a neurological or psychiatric disorder, and an inflammatory disorder.

The invention relates to a process for the preparation of a composition including free amino acids, oligopeptides and polypeptides, characterized in that the process comprises at least the following step: adding at least two different peptidases, which are present in purified form, to a composition comprising at least one protein.

An energy composition includes a methylated xanthine, a choline derivative, and at least one flavorant in a sufficient amount to render the energy composition palatable. The energy composition may also include vitamins, amino acids, enzymes, preservatives, and the like.

The present invention generally relates to compositions and methods for supporting exercise performance or activities of daily living. The compositions described herein are pharmaceutical or nutritional compositions suitable for enhancing exercise performance. The compositions are based on a specially formulated mixture of essential amino acids (EAAs) with additional components. The compositions target support of muscle protein synthesis and reduction of muscle breakdown during exercise, increasing muscle blood flow during exercise, decreasing the perception of fatigue by supporting optimal availability of neurotransmitter precursors, providing energy for rapids bursts of exertion during exercise, and maintaining adequate electrolyte balance during exercise.

The present invention relates primarily to the use of certain hydroxybenzoic acid amides or the salts or mixtures thereof for masking an unpleasant taste impression, preferably of a bitter, adstringent, dusty, dry, floury, rancid, metallic and/or cardboard taste or aftertaste, of one or more unpleasant-tasting peptides or of certain amino acid mixtures. The invention further relates to a corresponding method for masking unpleasant taste impressions and to novel preparations.
