Provided are a composition of a dietary supplement and a nutritional additive for food, a unitary dosage form of said composition, and their use for the improvement of the quality of visual performance including contrast sensitivity. An illustrative composition of the present disclosure includes as active substances L-lysine, vitamin C, zinc, grape extract and bitter orange extract in therapeutically effective quantities, and optionally at least one excipient. In some embodiments, the percentages of the individual active substances relative to the sum of the percentages of all active substances are about 50% by weight of L-lysine, about 15% by weight of vitamin C, about 2% by weight of zinc, about 10% by weight of the grape extract and about 23% by weight of the bitter orange extract, with all percentages of the individual active substances adding up to 100% by weight of all active substances.

Provided are methods of making and using an antimicrobial composition, optionally including adding one or more enzymes to a suspension of lees, wherein the lees was formed by fermenting fruit with yeast and the one or more optional enzymes comprise a protease, a carbohydrase, or a combination of a protease and a carbohydrase; and forming a dried lees by drying the lees. In some examples the fruit includes chardonnay grapes, pinot noir grapes, cabernet franc grapes, or a combination of any two or more of chardonnay grapes, pinot noir grapes, and cabernet franc grapes; the yeast includes one or more Saccharomyces cerevisiae strains of yeast; and drying the lees by heating it. In some examples, trub made from fermenting a grain such as barley is used instead of lees. An antimicrobial composition made as provided may be administered to an animal to inhibit bacterial growth.

Contemplated compositions and methods are based on a combination of polyphenols commonly found in the Mediterranean diet that, when combined, reduce pro-inflammatory signaling and expression of senescence-associated genes and support mitochondrial biogenesis and cellular energy metabolism. Notably, the observed pleiotropic effects did not only span across multiple signaling pathways, but also exhibited synergistic activity with respect to a number of markers associated with reduction of age-related decline in energy, immunity, and increase or persistence of chronic subacute inflammation. Viewed from a different perspective, contemplated compositions represent a symphony of biochemically diverse molecules that form the foundation for numerous benefits typically observed with the Mediterranean diet.

An extract of an herbal composition comprising at least two different dried plants useful as antimicrobial and/or antibiofilm agent in the treatment or prevention of microbial infections caused by bacteria, such as for example Escherichia, Klebsiella, Listeria, Pseudomonas, Salmonella, Streptococcus or Staphylococcus, or by fungi, such as for example is herein described. It has been found that in such extract, the active ingredients exert their biological effects in a synergistic manner. The extract may constitute the active ingredient of a food supplement, a nutraceutical, pharmaceutical or cosmetic composition or a functional food or a food additive. A process for preparing said extract is also described here.
