Compositions comprising an urolithin compound
The invention provides compositions comprising a source of protein and a urolithin. The invention also provides uses and methods associated with, or making use of the compositions, such as a medicament, dietary supplement, functional food or medical food and in the treatment and/or prophylaxis of a muscle-related pathological condition. The invention also provides kits comprising urolithin and protein.
1. A composition comprising:
a) a source of protein; and
b) urolithin A.
2. The composition of claim 1 , wherein the urolithin A has a D 50 size in the range 0.5 to 50 μm and a D 90 size in the range 5 to 100 μm.
3. The composition of claim 1 , wherein the protein makes up 20-99% w/w of the composition.
4. The composition of claim 3 , wherein the protein makes up 30-80% w/w of the composition.
5. The composition of claim 1 , wherein the weight ratio between the protein and urolithin A is in the range 2:1 to 5000:1.
6. The composition of claim 1 , wherein the protein is hydrolyzed.
7. The composition of claim 6 , wherein the protein is derived from milk, animal, cereal or vegetable sources.
8. The composition of claim 7 , wherein the protein is selected from intact pea protein, intact pea protein isolates, intact pea protein concentrates, milk protein isolates, milk protein concentrates, casein protein isolates, casein protein concentrates, whey protein concentrates, whey protein isolates, sodium or calcium caseinates, whole cow's milk, partially or completely defatted milk, soy protein isolates and soy protein concentrates, and combinations thereof.
9. The composition of claim 1 , wherein the composition is in the form of a yoghurt.
10. The composition of claim 1 , wherein the composition is in the form of a solid, a semi-solid, a powder or a liquid.
11. A method of treating a muscle-related pathological condition, comprising administering an effective amount of a composition of claim 1 to a subject in need thereof.
12. The method of claim 11 , wherein the muscle-related pathological condition is selected from musculoskeletal diseases or disorders; muscle wasting; myopathies; neuromuscular diseases; sarcopenia; and muscle atrophy or cachexia.
13. The method of claim 11 , wherein the subject suffers age-related decline in muscle function, age-related sarcopenia, age-related muscle wasting, physical fatigue, muscle fatigue, or is frail.
14. The method of claim 11 , wherein the subject is pre-frail.
15. A method of treating a muscle-related pathological condition, comprising administering to a subject in need thereof an effective amount of urolithin A; and an effective amount of protein; wherein the administrations are separated by a time interval.
16. The composition of claim 1 , wherein the protein is partially hydrolyzed.
17. The composition of claim 1 , wherein the protein is a non-hydrolyzed protein.
18. The composition of claim 1 , wherein the protein is derived from milk, animal, cereal or vegetable sources.
19. The composition of claim 18 , wherein the protein is selected from intact pea protein, intact pea protein isolates, intact pea protein concentrates, milk protein isolates, milk protein concentrates, casein protein isolates, casein protein concentrates, whey protein concentrates, whey protein isolates, sodium or calcium caseinates, whole cow's milk, partially or completely defatted milk, soy protein isolates and soy protein concentrates, and combinations thereof.
