The title says it all. I've been battling intermittent, but still consistent brain fog and tiredness the last few years. It wasn't until a blood test showed I was B12 deficient that I did something about it, and I'm not joking, it's like getting my life back. I take acid reducers every day for my GERD (something I hate, but I can't seem to get rid of any other way) and they prevent your absorption of cyanocobalamin, the most common B12 you find in foods and vitamins.
After a shot and several weeks on a high dose B complex with methylcobalamin (the neuro-active methyl B that your body can readily use), the difference is staggering. It happened gradually, but it happened. I have not had this much stamina in years.
Yesterday I worked a full day, trained for almost two hours, cleaned my house, ran with my dog and kids and had some fun adult playtime with my girlfriend and I still had a little left in the tank.
Anyone else ever in this boat?
