Thanks all, and noted.
I am also gonna try to give her B12 shots 2x weekly.
I am an MMA fighter and this has been an area of great importance to me.I have dedicated countless hours in the past couple of years, trying to figure out the best ways to increase and sustain overall energy and stamina.
One way or another (via injections or oral), you will find MUCH more results with a B-complex. I believe some injectibles include a B-complex already in the formulation. I use an oral B-complex (1000-2000mcg B-12) with great results. I also dose twice a day.
In relation to energy, ATP production within the body is of great concern. I think a quality (non caffeinated) Nitric Oxide enhancer would work very well in her case (worked well for my lady friend).
A key component in the proccess of ATP production is creatine. This is why a lot of NO boosters include smaller amounts of creatine in their formulations.
If you do decide to try this approach, look for L-citrulline/L-arginine/L-norvaline blends along with creatine (prefferably CEE). I can assure you.... if the product that you end up with contains that specific blend, it will work better than anything else that dosen't.
One more supplement I use daily is PEAK ATP with GlycoCarn by Life Extension. It contains an orally active form of the energy producing molecule ATP. Life Extention put a enteric coating on the capsule to ensure delivery into the small intestine for maximum bioavailability.
Good luck and keep us posted on her results and what you ended up going with.
