Yes, take one formulated for people over 50.  The only supplements that
have any reasonable effect on fat loss are the EC stack and maybe, just
maybe, chromium piccolinate if you are already insulin resistant.

I take rather a lot of vitamins.  Here's what I take:

A generic multivitamin
Extra calcium
500 mg vitamin C (just 'cuz)
400 mg vitamin E (I just like anti-oxidents)
Gingko Biloba (to dilate my blood vessels and maybe prevent alzheimers)
Niacin (the kind that makes me flush to dilate my blood vesseles)

I used to take chromium piccolinate but I no longer have metabolic
syndrome and don't bother anymore.

I sometimes take a glucosamin/chondroitin/msm combination for my aging
joints.  Those pills are big and I don't always pack them.

I make my husband take some plant stanols for his high cholesterol along
with a pretty high dose of Niacin and a baby aspirin.  He takes most of
the same vitamins except the calcium.

I sometimes add a quarter aspirin, some caffeine, some Ephedrine HCl
(this is the ECA stack) and is highly controversial.

One good thing about this vitamin regimen is that it requires me to
drink a lot of water to get it down.  Sometimes I suspect that's doing
more good than all the pills.  :-)
