Even with this site being geared towards people who are trying to loose weight, I find it severely lacking in terms of tracking supplements. I take amino acids, glucosamine, l-carnitine, and a few others. I can't track any of them since there isn't even an amino acid category.
The interesting thing is that the serious body builder is going to be paying close attention to their amino acid intake. Secondly, any vegetarian needs to make sure they are getting all 9 amino acids that aren't produced by our body. Both applications would set fitday apart from the other nutrition sites. I would really like to get some input on this from the mods.
