I'm sure you know this...but I'll say it anyway. What's currently fashionable as a supplement may not pass the test of time. I'm not afraid to say I've fallen for the hype in the past...
That said, here's a list of what I take (in order of importance):
Fish Oil - 12 to 16 grams per day divided into three or four doses
Glucosamine/Chondroitin three times a day
Multivitamin
BCAA - I am absolutely convinced this works in terms of recovery and protein sparing (people who try it without success just don't take enough and get the timing wrong); ever since I've been supplementing with this, I continue to hit some form of
PR, be it in the gym or on the bike, every month
Aspirin
I get calcium from dairy and veggies such as broccoli.
My GF is trying to wane me off coffee and onto green tea; and I know I should make the switch but I'm a shameless addict to the dark ambrosia
