Snack, if I remember correctly, you said you'd only recently begun to exercise seriously (within the past 6 months or so). If my memory serves me well, then the need for supplements should be nil. As you've seen, I'm a dude of some fair dimensions at 210, 6'3". That being said, even at my weight and height, I personally have no need for supplements.
That isn't to say one shouldn't take them, but I wouldn't worry too much about them. Generally though, supplements are not a good idea, simply because the supplement industry is entirely unregulated and most products will have toxic (yes, toxic--renal, hepatic and many other kinds of toxic) filler in them. Muscle Milk, EAS and a few others, for instance, tested positive for cadmium, mercury, arsenic and a few other nasty heavy metals. In fact, Bodybuilding.com was recently fined $7,000,000 for selling steroid-laced supplements back in '09 or so.
Just so no one thinks I'm bull****ting them about not needing supplements, here's a comparison of me two-and-a-half years ago and about five months ago (right and left, respectively).
When I first started off, I naively took supplements for about 3 months, but I don't think anyone in their right mind would argue that three months on a soy supplement while not really even lifting would create results.
So yeah. Hope all that's helpful. It's totally one's choice to do so if it makes them feel better, but hopefully my personal progress is fair evidence that supplements aren't a necessity. I get by on tuna, cottage cheese, oatmeal, milk, eggs and others kind of fish/poultry. I know it sounds nasty, but there're ways to make all of 'em taste amazing. Mix a little fat free mayonnaise into the tuna, put fruit into the cottage cheese and oatmeal and season the meat/eggs as you like. Though, if one were to buy a supplement, they should check all of the ingredients first. Only problem is that the <good> and natural stuff is way more expensive than just getting your protein through normal means. 5lbs for top-of-the-line powder is usually $50-90.
