I just went to the store and bought a Sublingual B12 supplement, and when I got home to look online about the recommended daily intake it says 2.5 mcg. This was alarming because the sublingual tablets I bought are 5,000 mcg, doesn't this seem like a lot? That's 2,000 times the amount.

Would taking these daily become a problem? I read that B12's Half-Life is up to 400 days, could taking such large doses everyday accumulate into too much for the body to handle?
 
No, you're fine. Just for an example I took a look at a vitamin C bottle I had near by, its 833% DV. Things to know are that DV is based upon a 2000calorie diet, so that of course changes based upon your weight, and supplements are usually always way higher than the recommend DV.

I used to take a ton of b-12 back in the day for piss coloring. I used to take b3(niacin), b6, and b12. B12 is fine, but Niacin - ever have a Niacin burn thats always fun.
 
I used to take them all the time (along with probably hundreds of thousands of people) you'll be fine.
 
Because it is water soluble and readily eliminated, it's fine to take that dosage.
 
I thought the large doses were because Vitamin B12 has a very, very low BA, so a very large amount is required to give you what you need.
 
^Is this true? I bought vitamin B12 last week for various reasons, and it's not 'that high' of a dose. I better not have wasted my money (and time getting to that damn CVS). What do you all take B12 for specifically, if I may ask?
 
Most B-12 is sublingual which is the best way to take B-12 next to I.M.'ing it. You consume it in mostly the meat you eat.

B-12 is practically destroyed in the G.I. tract. The more you take, the less is absorbed orally. That is why a huge dose of it is necessary. Not to worry, you consume way more than you are taking right now on a daily basis, if you don't have an eating disorder or something...
 
Ahh. I don't really eat meat. I take 500mcg a day, no eating disorder, just skinny enough to be medically anorexic(for lack of better term)=BMI 'test'; which I find irritating.

To OP - you looked online and it sayd 2.5mcg per day? That doesn't seem right at all...

Still - what benefits does this have? (I'm going to google it now...I'm looking for specifics and individually biased answers;) )
 
Sweet. I wonder if and when effects will be noted...(*scratches chin - but not TOO hard)./?
 
I'm a vegetarian and I take vitamins to supplement my diet. B vitamins, B-12 in particular, help provide me with energy (I'm an insomniac), and they make my mood a bit better. I generally take a sublingual liquid with multiple B-Vitamins in it, half or 1/3 of a vitamin B pill (the pill has a few that the liquid doesn't), and a multi-vitamin, spread out over the day.

I find 2000 + mcgs to be a good dose, the B-12 sublingual stuff I first bought was tabs that were 500 mcgs each and I didn't notice much until I started doing 4 at once as a dose. The injections work a lot better then the sublingual, which works better then the oral. Oral B-12 barely works. I definitly notice a difference in energy levels when I take vitamin B-12, although I recomend sublingual liquid instead of tabs because the liquid often has multiple vitamins (mine has B-2, Niacin, B-6, B-12 and Pantothenic acid), it seems to work better for me (it certainly is quicker and easier for me to deal with) and is usually a higher dose, most of the tabs I've seen were 500 mcgs whereas the liquid often has over 1 mg (mine has 1.2) per cc (one cc=a recomended dose).

Also, according to the B complex sublingual liquid I have, 1.2 mg is %20,000 of the daily value. I don't know if they change the dose to account for metabolism and what have you, but it seems as if they don't.
 
They don't. We normally consume thousands X the amount of B-12 we actually need.

We do with a lot of vitamins. Right off the bat, C, E, and A are the mostly consumed way pass the point of necessity.

We normally binge our body with water soluble vitamins. It literally takes grams upon grams of the daily value of some water-soluble vitamins to be harmful. If it were fat soluble, then you would be in deep shit in a matter of hours.
 
I know exactly the supplements you're talking about! I picked up a bottle myself a month ago and have been putting one of those little puppies under my tongue every day before I leave the house.

Can't say I noticed ANY difference in the way I feel lately. With such a high dosage, I was expecting to feel SOMETHING, but oh well. B12 is supposed to be good for us addicts, so I keep taking it, assuming it's helping me somehow...
