well, to 'tone' you need to reduce bodyfat, and to do that you need to watch what you eat, and how much. as long as you're taking in 10-20% fewer calories than your daily needs, you'll be shedding bodyfat.
the main supplements a woman should avoid are ones specifically targeted at increasing the male hormone testosterone.
most of those products don't work , or are sketchy to begin with, but as a woman you don't really want a lot of Test.
multivitamin
protein powder
fish oil
creatine hasn't been studied on women, but the basic nature of what it does implies it's effective for women too, but I'd take just 3g a day if you went with that.
You'll notice I didn't list fat burners or diet pills. you shouldn't need those, and a lot of them are bogus anyways.
also, what's wrong with gaining 7 pounds of muscle? that's not a whole lot, and muscle uses calories. Again, you are a woman...you don't have testicles or enough testosterone to get 'huge'.
do not confuse weight training and gaining muscle, with the female pro-bodybuilders that use anabolic steroids to achieve their masculine figures.
steroid using female:
natural female:
see the profound differences between natural and 'enhanced'? do NOT worry about getting 'too bulky and unfeminine'.
