Is the Lin Yuzhi Friends Account valid? Do the elderly eat well and absorb it?

With the increase of age and the loss of bone nutrition, the problem of backache and leg pain will appear. At this time, it is quite good to eat Lin Yuzhi's friends' memory, which adopts the patented technology of ultrafine grinding. Old people can eat and absorb well, so they can rest assured. I would appreciate it if you could take my answer. If you need anything else, you can ask, thank you!
