Safe during nursing?

[help]

Is there a good website that lists what herbs/supplements are safe during nursing?  I have been told to take l-glutamate, taurine, and glycine, but I have no idea if they're safe during nursing.  I've checked kellymom.com and didn't see anything.

Anyone know?

Thanks,

Crystal
