I take every single one depending on my goals at the time, with the exception of glutamine. While I believe it may help immune function with higher training loads, that doesn't really apply to me. I take a daily multi-vitamin, 10g fish oil, whey or milk protein isolate, 5g creatine monohydrate. I don't take any antioxidant supplements, just about 2-3 cups of green tea a day and a bunch of fruits and vegetables.
As for fat burners... they have gotten a bad rap and a lot of it is for good reason. Most, if not all advertised is over-priced junk designed to sell to people looking for the easy way out. However, there are a few if used correctly can be very helpful. The EC stack is just one example, which blunts hunger, decreases muscle loss, gives you energy, and raises metabolic rate slightly. However, it must be used responsibly and in addition to a solid diet and training program, not in place of. Another one I use from time to time is Yohimbine, which is very helpful when approaching very lean levels (going from say 10% to 6-7%). Since yohimbine inhibits alpha-2 receptors taken with caffeine to jack up catecholamine output does wonders for stubborn fat loss. However, most people don't really need it until they reach really lean levels and many males can get that lean without any stubborn fat issues at all. Many will claim they have stubborn fat issues, but it's just a case of there diet not being that great. There are still plenty of men out there (myself included) that have a problem with low back and low abdominal fat though. The real problem is women who hold a lot of their fat in their lower bodies. Anybody who has seen a women with a ripped upper body, but chubby legs knows exactly what I'm talking about.
Just like anything else, they must be used responsibly, which doesn't always work out too well since most peoples attitude about things is "more is better."
