I would watch the fishoil intake - don't over do it.
One thing I do know is that fishoil makes you bleed like a stuck pig!
I have been in surgeries which had to be bailed out of because of excess bleeding due to fishoil. The main problem for surgeons is that patients think of it as a supplement so don't mention its use pre-op as they would the drugs they are taking.
One more thing to think about while out on the trails. Wouldn't want a normally minor injury to become life threatening through an inability to clot adequately.
