Not too expensive - especially when GNC has their sales.
Chromium (picolinate form) was thought to be efective in increaseing insulin sensitivity - which is a good thing for muscle growth and fat loss. But some of the studies are suspect. Glutamine is not normally in a multi vitamin at all. I do 5000 mg ( 5 gram) doses in pure powder form immedialtely after rising, after workout and prior to bed along with 1000 mg (1 gm) dose of vitamin C. There are a bunch of threads around here talking about glutamine - but its not necessssary if you are just wanting to tone up and not grow. Calcium and Vitamin D are not the same thing. They are usually present together since they compliment each other in bio availability/absorption.
Vitamin C is usually used for its anti-oxidant capabilities. Since exercise can release a lot of damaging free radicals. Most multi vitamins have the three big anti oxidants already (vitamin A,C,E) in pretty high mega dosages. This should be sufficient to get you going. Some people also add a fat soluable anti ox to help combat the free radicals in the fat tissue (e.a. Alpha Lipoic Acid or ALA). The A-C-E vitamins are water soluable and do not help much in neutralizing the free radicals in the fatty tissue.
My recommendation is to just get a good multi vitamin and then fine tune later with other specific things you may want to try. For example, as a guy I also ingest a lot of tablet form garlic. This is suppose to be a natural testosterone booster. A lof of women like to use standardized gree tea tables or just drink green tea. It's a highly personal thing.
