B12

I am a firm believer for all illnesses to ask for a metabolic panel to be ran. I happened to go to a VA hospital in Ann Arbor MI because i have many issues. the Dr. there ran one and found my B12 was super low. I know you can take it in a pill but B12 is an intrinsic factor and i believe is made in your pancreas. (digging from my college brain that is froggy..) He told me the only way to build up back to a sufficient amount.... it should be above 200-900 is by injections because your body doesn't metabolize it as well. I took shots for 7 days in a row. I have mine checked about every year. It made a huge difference on my fatigue at the time. It is a simple blood test that often is over looked. But with the way people eat, we often are filled with chemicals or preservatives and are not getting quite the nutrition we need.

the internal med doc i had because of my illnesses i was about 290 and he wanted me at a high range. When i got to 800 I stopped injections. Any way. Google B12 intrinsic factor. It talks about how important it is for your nervous system. I also read that it is stored in the liver, and they do sell sub lingual tablets but the best way is injections.

I hope people read these because it talks a lot about how it affects Brain fog, optic nerve, (vision) and i think it just answered a lot of symptoms i have recently had that had or have been increasing.

Bucci... thank you for posting.

The only thing about B12 now, in contrast to B12 back around, say, 1976, is that every supplement I have looked at only doles it out in MICROgrams instead of milligrams.
I started bodybuilding back in 1970, obviously well before the current craze. I used a balanced B vitamin, in which EVERYthing was a 50 milligram (or 100 milligram) dosage, so there was sufficient strength in it. I was pretty disgusted when I bought it earlier this year and saw that nearly every manufacturer -- including the company that I used back in 1976 -- only provides them in doses 1/1000 of what they used to. Another good one is B15, which is, unfortunately, not easily found in stores. It is called calcium pangamate. I used to use balanced B, 1200 units of E, and 100 mg of B15 before working out. I found working out easy (but then, I was around 20 as well!) and got results very quickly.
B12 is an excellent energy vitamin, and I think doing a panel, as the other poster noted, is an excellent idea. It is not, however, something doctors routinely think to recommend. Most tests results simply come back "within the 'normal' range" which is silly, as every body is different and some need more of a mineral or vitamin and some need less.
