N2Joint is a complete joint product. If you wanted to add other things for healing then these are what I would read about:
-Ostarine
-Nutrobal
-HGH
-fish oil
In addition to fish oil, look into krill oil.
Krill oil has a lot of extra benefits associated to it that fish oil does not provide.
Krill oil is basically oil extracts from minos (baby fish). It's kind of like comparing broccoli sprouts to broccoli. Both are healthy foods but there are some additional health benefits associated with the broccoli sprouts.
