    I hear that B12 vitamins give you good energy...would you guys recommend it before working out? Sometimes after work I get a little sluggish, which is not good considering most of my workouts are circuit-based. Thoughts?

    Neither - it really won't do much for you.

    Unless you have a high pain tolerance and you have access to a bag of syringes it's a waste of time
    B12
    can't be absorbed through the GI tract
    Your digestive system. Breaks it down before your body can use it

    umm.. according to every doctor I've ever been to it is absorbed just fine unless you have a stomach problems, as well my blood works will prove B12 is absorbed just fine too, I take a B12 supplement every day due to deficiency, my stomach causes problems.

    but, B12 is absorbed into the body in the last section of small intestine.. BUT for B12 to be absorbed into the blood it needs to bind with a glycoprotein if I remember correctly it's called and I shit you not an "intrinsic factor" and after absorbtion it binds to transcobalamin which is a carrier protein which is found in blood and then it attaches to something else astoundingly called transcobalamin II.

    For me, my stomach does something which means I don't absorb enough B12 SO, I take a supplement which means there is more there to potentially be taken in by my body AND it does... saves me having to have a needle which I hate.

    You're asking will it be a benefit taking it "before" a workout.. NO. It doesn't work like an aspirin with near immediate results. If you have a vitamin deficiency you take these types of supplements on an ongoing basis, either daily in pill or liquid form or with vitamin shots.

    This. Maybe over time it would give you more energy, but it would be a waste of money to treat as a pre-workout energy booster.

    I supplement with a B12/Folate injection (self administered) twice a week. Prescribed and monitored by my doc. Cost is $70 for eight weeks, including insulin syringes.

    I inject in the same site, same time, same days each week, and I blood test every eight weeks to monitor absorption (I suffer from ) and I inject prior to my workout (only because I workout in early a.m.) I notice a slight increase in endurance energy on those days, but not significant enough to say it's going to solve your problem.

    I'd suggest asking your doc to do a full panel including an iodine patch test, testosterone levels, cortisol levels and a look at your thyroid. Most docs work with a 'range' and are satisfied with numbers within the norm. SMART docs are looking for optimal positioning of those numbers based on your age, activity, general health and other factors UNIQUE to you. Insist on a discussion about the latter, and fire anyone just plugging you in with the former.

    Good luck.

    Enzymatic makes a chewable that is absorbed through the mucous membranes of the mouth as you chew it and it does help some. I take it daily.

    B12 is absorbed by the terminal portion of the small intestine (the ileum) with help from 'intrinsic factor', a substance produced in the stomach's parietal cells. Unless you've had stomach or bowel surgery, you likely already have an excellent store of B12 in your body given the rich sources in Western diets. In fact, you could stop all intake today (in food, pills or injections) and it would be years before you would see 'low' levels in your body. B12 is water soluble... excesses in the form of pills or injections are excreted. B12 is a waste of money if you eat well. we refuse to prescribe it in our office because we are wasting our patients' money if we prescribe it. anyone who professes to get benefit from it is having a placebo effect, unless they have a legitimate, clinically-proven deficiency (which is rare).

    As you get older, your body absorbs B12 less readily. That's why if you look at the Senior vitamin pills, they have like 16,666% of your requirement.

    That aside.

    You need the full compliment of B vitamins for energy production. The B vitamins are the components of the electron transport chain in the mitachondria where ATP is made.

    I drink FRS. Its a drink endorsed by Lance Armstrong. (Which is why I tried it. I figured he didnt have endorse anything he didnt want to. And if I was being snookered, I was gonna be snookered by the best!) It really works for me. Both in the gym and for mental energy at work in the afternoons.
