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) micronized urolithin A;
wherein the micronized 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.
2. The composition as claimed in claim 1 , wherein the protein makes up 20-99% w/w of the composition.
3. The composition as claimed in claim 2 wherein the protein makes up 30-80% w/w of the composition.
4. The composition as claimed in claim 1 , wherein the weight ratio between the protein component and the micronized urolithin A is in the range 2:1 to 5000:1.
5. The composition as claimed claim 1 , wherein the protein is hydrolyzed.
6. The composition as claimed in claim 5 , wherein the protein is derived from a source selected from milk, animal, cereal and vegetable sources.
7. The composition as claimed in claim 6 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.
8. The composition as claimed in claim 1 , wherein the composition is in the form of a yoghurt.
9. The composition as claimed in claim 1 , wherein the composition is in the form of a solid, a semi-solid, a powder or a liquid.
10. The composition as claimed in claim 1 wherein the composition is a medicament, dietary supplement, functional food, functional beverage or medical food.
11. The composition as claimed in claim 10 wherein the composition is a medicament.
12. A method of treating a muscle-related pathological condition comprising administering to a subject in need thereof an effective amount of a composition as claimed in claim 1 .
13. The method as claimed in claim 12 , wherein the muscle-related pathological condition is selected from musculoskeletal diseases and disorders; muscle wasting; myopathies; neuromuscular diseases; Duchenne muscular dystrophy; sarcopenia; muscle atrophy; and cachexia.
14. A method of increasing muscle performance comprising administering to a subject an effective amount of a composition as claimed in claim 1 .
15. The method as claimed in claim 14 , wherein the subject suffers age-related decline in muscle function, age-related sarcopenia, age-related muscle wasting, physical fatigue, muscle fatigue, or is frail.
16. The method of claim 15 , wherein the subject is frail.
17. The method of claim 15 , wherein the subject suffers age-related sarcopenia.
18. The composition of claim 1 wherein the micronized urolithin A has a D 90 size in the range 8.2 to 16.0 μm, a D 50 size in the range 2.8 to 5.5 μm, and a D 10 size in the range 0.5 to 1.0 μm.
19. The method of claim 12 , wherein the muscle-related pathological condition is selected from musculoskeletal diseases, musculoskeletal disorders, muscle wasting, myopathies, neuromuscular diseases, muscle atrophy, and cachexia.
20. The method of claim 12 , wherein the micronized urolithin A has a D 90 size in the range 8.2 to 16.0 μm, a D 50 size in the range 2.8 to 5.5 μm, and a D 10 size in the range 0.5 to 1.0 μm.
21. The method of claim 14 , wherein the micronized urolithin A has a D 90 size in the range 8.2 to 16.0 μm, a D 50 size in the range 2.8 to 5.5 μm, and a D 10 size in the range 0.5 to 1.0 μm.
