Administering an amino acid-containing composition, containing the following amino acids (1)-(9), wherein the molar content ratio of each amino acid to the total content of the amino acids (1)-(9) falls within the following numerical ranges: (1) leucine 35-66%; (2) isoleucine 5.0-15%; (3) valine 5.0-15%; (4) threonine 7.0-14%; (5) lysine 8.0-16%; (6) methionine 2.0-10%; (7) histidine 0.1-3.5%; (8) phenylalanine 2.5-8.0%; and (9) tryptophan 0.1-2.0%,
is effective for enhancing recovery from muscle fatigue.

Compositions containing one or more kinds of essential amino acids other than leucine and not less than 35 mol % of leucine, relative to the total content of essential amino acids, s are useful for preventing or improving dementia or a depressive state, in particular, a depressive state caused by stress, have high safety, and can be continuously ingested or administered.

The present invention provides compositions and methods for improving the quality of life for a subject, particularly a child, diagnosed with autism spectrum disorder (ASD). In preferred embodiments, a supplement composition comprising natural or naturally-derived ingredients is delivered to a subject in the form of a chocolate bar or other candy alongside administration of an antiviral medication. Advantageously, the composition and methods can improve the immune health of the subject, along with other signs and symptoms associated with ASD, infections and other immunocompromising conditions.

A method of preventing protein glycation using a supplement may comprise: administering a supplement comprising lysine and zinc; monitoring a concentration of glucose before and after the supplement is administered in a bio-sample; and determining a change in a dose of the supplement based on the concentration of glucose found in the bio-sample.

Methods, compositions, and systems for fermentation, particularly large scale operations for production of ethanol and dried distiller's grain are provided. Addition of a transglutaminase source to a process stream aids in removing protein from the system in order to provide a high protein feed product and/or provide clarified backset for fermentation. Transglutaminase can be in reagent form or can be produced by microorganisms added to the process stream.

A nutrient composition comprises an essential nutrient in which at least one exchangeable H atom is .sup.2H and/or at least one C atom is .sup.13C. The nutrient is thus protected from, inter alia, active oxygen species.
