b-12

how often can you take b-12 1000mcg

 In what form?

I take my MethylCobalamin Sublingual B-12 (1,000 mcg) daily.

In cap/tab form one could go daily too.  But, you may need more to ward off deficiency.

Try it daily for a month and have your levels checked.  A dose of 1000 mcg has not been shown to have toxic effect.

I take 1000mcg b-12 sublingually each morning. It's supposedly not toxic since you just **** out what you don't use. On the other hand, B12 deficiency can cause severe and irreversible damage to the nervous system. Since we WLSers don't absorb b12 very well there's pretty much a general consensus recommendation by our nuts  for us to take it in some form or fashion. The only question is how much and often.
 
Bottom line for me personally is that B12 is supposed to increase our energy levels so good enough for me since it's nontoxic and inexpensive.

Some people don't absorb enough B 12 no matter how many you put under the tongue.  For us, shots or the nasal spray is a must.  Your doc has to decide that based on your blood numbers history.

One shot in my thigh every two weeks for me. Been doing it for a couple of years that way and seems to be working fine.

I was taking 2 500mcg sublingual a day, at my last labs they told me I could go to just one a day. Your labs will let you know if you are geting enough. Like everyone else said any extra is passed through.

I do 5000-10000 a day. If I pee it out OK but I am NOT having another B12 deficiency
