liver/brewers yeast challenge

[Vaquitita]

I can't seem to find the old thread, but wanted to ask a question...

I've been taking brewers yeast for 9? or more months now and it did give me more energy, etc. But now that I'm 6 months preg, though I feel pretty good, I just do not really having enough energy to keep up with my toddler. Do you think doubling the amount of brewers yeast i'm taking would help? Or maybe taking some liver tablets? There really isn't any 'overdose' on these things right? I'm thinking it couldn't hurt to try...

How do these liver capsules look to you? Carlson's Buffalo Liver
They also sell these, but while they're raw liver it doesn't say anything about being grassfed which the Buffalo capsules are. Which is more important? I'm guessing grassfed is better than raw conventional liver.
