Abstract: Composition comprising a combination of oleuropein or metabolite thereof and nicotinamide riboside thereof are provided. The composition may be an oral nutritional composition, for example a nutritional supplement, an oral nutritional supplement, a food product, a food for special medical purpose (FSMP). The composition can be administered to an individual in need thereof for (i) improving a physiological state or disorder related to NAD deficiency/restriction in one or more cells, (ii) improving a physiological state linked to metabolic fatigue in one or more cells, (iii) increasing mitochondrial energy and mitochondrial calcium uptake in one or more cells, and (iv) increasing antioxidant capacity, reducing oxidative stress and/or enhancing mitochondrial function, (v) treating or preventing a NAD deficiency/depletion disorder in an individual, (vi) improving healthspan.

Abstract: The present invention relates to use of a composition comprising an effective amount of a combination of oleuropein and/or metabolite thereof and quercetin and/or derivative for maintenance of joint health or prevention or treatment of joint disorders in an individual. In particular, the invention relates to a composition comprising an effective amount of a combination of oleuropein and/or metabolite thereof and quercetin and/or derivative for use to prevent or treat cartilage degeneration in an individual.

The composition can be administered to an individual in need thereof for improving a physiological state linked to metabolic fatigue in one or more cells, (ii) increasing mitochondrial energy and mitochondrial calcium uptake in one or more cells, and (iii) increasing antioxidant capacity, reducing oxidative stress and/or enhancing mitochondrial function, (iv) treating or preventing a calcium deficiency/depletion disorder in an individual. Additionally, or alternatively, the method can treat or prevent a mitochondria-related disease or a condition associated with altered mitochondrial function in an individual in need thereof or at risk thereof.

Abstract: A method of preventing or treating muscle fatigue from exercise and/or for resistance to muscle fatigue from exercise, the method including orally administering at least one of oleuropein or metabolite thereof to an individual before, during and/or after the exercise. A unit dosage form contains at least one of oleuropein or metabolite thereof in an amount effective for administration of the unit dosage form before, during and/or after exercise to thereby prevent or treat muscle fatigue from the exercise and/or for resistance to muscle fatigue from exercise. A method of making a composition for preventing or treating muscle fatigue from exercise and/or for resistance to muscle fatigue from exercise, the method including adding an effective amount of at least one of oleuropein or metabolite thereof to at least one ingredient selected from the group consisting of protein, carbohydrate, and fat.

Abstract: A composition effective for restoring mitochondrial and other cellular function and/or increasing mitochondrial energy in one or more cells contains adenosylcobalamin. Other aspects are directed to method of improving in a physiological state linked to metabolic fatigue in one or more cells and/or reducing fatigue in an individual; method of treating, reducing an incidence of, and/or reducing a severity of a chronic illness and/or of a mitochondria-related disease or condition associated with altered mitochondrial function or a reduced mitochondrial density.

Abstract: A combination of calcium and at least one of oleuropein or metabolite thereof can be orally administered to an individual in an amount effective to decrease muscle fatigue in an individual who participates in at least one of 1) resistance exercise, 2) anaerobic or repeated sprint-type exercise, or 3) endurance exercise. Preferably, the combination of calcium and at least one of oleuropein or metabolite thereof is administered to the individual less than two hours before the exercise, and/or during the exercise, and/or less than two hours after the exercise.

Abstract: A combination of calcium and at least one of oleuropein or metabolite thereof can be orally administered to an individual in an amount effective to achieve at least one result that is (i) improved mitochondrial calcium uptake in muscle cells, (ii) improved utilization of calcium in muscle cells, (iii) increased mitochondrial energy in muscle cells, (iv) improvement in at least one of muscle functionality, muscle performance, or muscle strength, (v) decreased muscle fatigue, (vi) increased mobility, and/or (vii) treatment of a muscle disorder linked to calcium depletion or deficiency. The individual can be at least one of an aging subject; an elderly subject; a subject with muscle fatigue or muscle weakness; a subject with impaired mobility; a frail subject; a pre-frail subject; a sarcopenic subject; a subject recovering from pre-frailty, frailty, sarcopenia or impaired mobility; a subject undergoing physical rehabilitation; a sportsman; or a pet.

Abstract: At least one of oleuropein or metabolite thereof can be orally administered to an individual in an amount effective to achieve at least one result that is one or more of (i) improvement in a physiological state linked to metabolic fatigue in one or more cells, (ii) increased mitochondrial energy and mitochondrial calcium uptake in one or more cells, and/or (iii) treatment or prevention of a calcium deficiency/depletion disorder. Additionally or alternatively, the method can treat or prevent a mitochondria-related disease or a condition associated with altered mitochondrial function in an individual in need thereof or at risk thereof.
