1. A urolithin-containing aqueous solution containing urolithin and collagen,
wherein the total amount of collagen is 0.1 to 100,000 parts by weight with respect to a total amount of 1 part by weight of urolithin.
2. The aqueous solution according to claim 1 , wherein the urolithin is urolithin A.
3. A dried solid composition of the aqueous solution according to claim 1 .
4. A method for producing a urolithin-containing aqueous solution, the method comprising:
a blending step of blending urolithin with collagen.
5. The production method according to claim 4 , wherein the collagen is at least one selected from the group consisting of type I collagen, type II collagen, type III collagen, type IV collagen, and type V collagen.
6. The production method according to claim 4 , wherein the urolithin is urolithin A.
7. The production method according to claim 4 , wherein the total amount of collagen is 0.1 to 100,000 parts by weight with respect to a total amount of 1 part by weight of urolithin.
8. A method for producing a dried solid composition of a urolithin-containing aqueous solution, the method comprising:
a blending step of blending urolithin with collagen; and
a drying step of drying the urolithin-containing aqueous solution obtained by the blending step.
