I'm also taking joint health (what a decrepit collection of old buggers we are!). My family won't let me back on SCUBA until my knee will bear my full weight without pain, so it's up and down in the pool. Forty boring lengths.

I don't know if the Joint Health helps, but a hundred years ago I researched the biology of mussels with a view to farming them. At that stage, the MacFarlane Mussel Co produced "Seatone" which a peer reviewed paper showed reduced inflammation in rats.
