I know there are a lot of threads abot B12 [which is why I am going to pick some up this weekend], but I'm wondering if anyone can recommend a specific brand or type of B12 supplement you take. I know when I go to GNC there are going to be numerous to choose from!
Also, I was thinking about getting a weekly one [2000 Micrograms] because I'm not very good at remembering to take my vitamins!
It's my understanding that you only need 2 mg a day. I drink Rice Dream rice milk, Pacific organic oat milk, and eat nutritional yeast.
I know that many people differ on weather or not vegans can get all their b12 from fortified foods and some plants, however some people believe that plants can not provide b12.
I don’t know if plants do produce b12 or not and if they do I don’t think that it is in the type that I eat. Therefore I take a 2000mg b12 once a week to make sure that I get my b12. I get mine from Holland and Barrettes but you might not have this shop where you are from. The one I get states that they are available for vegans so as long as it says that I don’t think that it matters what brand you buy.
I simply take a B complex tablet these days that contain 50mg of all the Bs except B12, for B12 there are 50 micrograms. Somehow I just don't want to overdo anything, and I don't take any other supplements such as iron or calcium etc, as in my view there are sufficient nutrients in what I eat.
I use Solgar b12. 1000 mircogram nuggets.Quote:

On the bottle it says "suitable for vegans"
It's can be true that you only need 2mcg a day, but some sources advice a higher intake.
Plus : not all what you take in can/will be absorbed, so it's wise to take a little more.
Here is an article I read in the magazine of the vegan society it's provides some info on why to take a little bit more b12 than the minium recomended daily intake:

Homocysteine & health
Article from The Vegan, magazine of the Vegan society, England, Winter 2002
By Stephen Walsh, PhD
The little known amino acid homocysteine has been the subject of great interest in the medical community since the early 1900s as evidence accumulated that even moderately elevated levels went hand in hand with increased risk of heart disease, birth defects, dementia, depression and death. Independent studies in Israel, USA, Norway and Holland have shown homocysteine to be strongly associated with mortality from all causes combined and thus a potentially greater risk factor than cholesterol: every 10% increase in homocysteine is associated with an 8% increase in mortality from all causes and a one year reduction in life expectancy.
A part from kidney disease and certain rare genetic defects, low intakes of any of three vitamins (folate, vitamin B12 and vitamin B6) can cause homocysteine levels to rise. Supplementation trials using folate, B12 and B6 to reduce homocysteine showed a reduction in symptoms of heart disease, including the rate of progression of atherosclerosis. Supplementation with 4 mg per day of folate reduced the incidence of neural tube defects such as spina bifida by about 70% while 0.8 mg of folic acid plus 4 micrograms (mg) of B12 reduced neural tube defects by 100%.
At first, there was considerable optimism that on a plant-based diet homocysteine levels would be lower, due to high folate levels, and a recent trial showed that homocysteine levels decreased within a week of switching from a typical Western diet to a vegan diet with plenty of vegetables. However, other studies have shown that many long-term vegans have blood homocysteine levels around 15 mmol/L compared with desirable levels below 10 mmol/L, while other vegetarians averaged about 12 mmol/L. This trend is not found in vegans ensuring B12 intake of 3 mg or more per day, who show the expected benefit from high folate and plentiful B6 with homocysteine levels around 8umol/L compared with a Western average of about 10umol/L. The bar graph shows the results of recent studies on homocysteine and diet.

With the exception of one study in the USA in 1999, the highest levels of homocysteine were observed in vegans, with lacto-vegetarian levels also higher than meat eaters. The critical role of B12 can be seen from the comparisons of B12 and folate intakes in the same studies. The B12 levels of vegans were generally the lowest, while the B12 levels of other vegetarians fell between those of vegans and meat eaters. In contrast, the vegan folate levels were generally higher than or similar to the other groups. In the 1999 USA study, the vegan B12 levels matched those of the meat eaters and so did the homocysteine levels. To remove any shadow of doubt as to the cause of the high homocysteine levels, the Chilean study subsequently monitored the effect of B12 supplementation: the homocysteine levels of the Chilean vegetarians dropped from 13 to 8 mmol/L with no other dietary changes.
Average vegan homocysteine levels are about 15 mmol/L. Based on studies in the general population, this degree of excess homocysteine could be associated with a 40% increase in mortality, particularly from causes other than cancer. Low vegan cholesterol levels would be expected to reduce heart disease deaths by about 50% compared with meat-eaters, so the overall result would be expected to be 30% less heart disease but 40% increased mortality from other causes, with little difference overall. This is almost exactly the pattern observed in the only study to report direct observations of vegan mortality (UK, USA and Germany 1999). The table shows the relative risk of death per year. Regular meat eaters (eating meat once or more per week) are taken as the reference point. The results are highly consistent with mortality expectations based on reduced cholesterol and elevated homocysteine combined.
www.geocities.com/one_vegan/img/deathfactor.jpg
The evidence suggests that getting adequate B12 could result in vegans living about 4 years longer than meat eaters and 2 years longer than lacto-vegetarians. It should be noted that the “ regular” meat eaters in this study ate less meat than the general population in their countries and none of the groups included many smokers. Mortality in the general population is about 1.6 in terms of the above table, so although the vegans studied lived no longer than the other groups they were already living about five years longer than their typical compatriots.
Homocysteine rises significantly long before B12 stores drop to the level associated with classical B12 deficiency. Current UK government recommendations of 1.5 mg per day are based on reliably preventing classical deficiency and are more than adequate for that purpose. However, they do not take into account B12 requirements to minimize homocysteine. At least 3 mg per day are required to achieve this by maintaining blood B12 levels at 300pmol/L or more. If the main source of B12 is a supplement taken daily, at least 10 mg should be taken.
If it is taken weekly, 2000 mg is required. The variation in recommended weekly intake is because absorption of B12 is best at small doses below 0.5 mg, where about 70% of available B12 is absorbed. As the dose approaches 10 mg, the amount absorbed flattens off at about 1.5 mg and only about 0.5% of further increases in dose are absorbed. The absorbed amount from 2000 mg is therefore little more than 10 mg, which is just enough for one week, while the same absorbed amount can be obtained from 3 mg per day spread across several meals or from a daily supplement of 10 mg.
A single weekly supplement of 2000 mg has the advantage that absorption does not rely on intrinsic factor in the small intestine, which is required for efficient absorption of small amounts of B12 and is occasionally absent, particularly in the elderly. All forms of fortified foods and supplements avoid the more common B12 absorption problem in the elderly, namely inability (usually due to declining stomach acidity) to separate the B12 in meat from the proteins to which it is bound. B12 supplements should be chewed to ensure reliable absorption.
From conception to death, elevated homocysteine casts its shadow, but the risk can be straightforwardly minimized by ensuring an adequate intake of vitamin B12 from fortified foods or supplements and consuming a varied plant-based diet with plenty of fruit and vegetables. This should allow the full potential of the vegan diet to shine through, giving vegans a clear lead over other dietary groups.

Great article, 1vegan. Thank you for sharing. :)
If I were to take a supplement, I'd get Veglife, I believe an all-vegan brand, http://www.vitaglo.com/vegl74345.html. The picture to click on and ask for more information isn't coming up right now. I think everything is vegan.
I use "Nature's Own' because they are cheap, vegan, and you can get them from the supermarket. Well, more accurately, I have them in the cupboard because I never ever remember to take vitamins.
I have mine near the frigde so I see them when I prepare food. (or I'll forget them too) :)Quote:

I only take a vitamin like once every 2 weeks or so, if I feel I haven't had enough food or varied food for the day. The multi I take has B12, too.
A great way to get extra B12 is to put nutritional yeast flakes in your favorite hummus recipe. It makes the hummus cheesy!
I just bought some nutritional yeast flakes but mine doesn’t say it contains b12. It lists a long list of B vitamins but there is no b12 to be seen.
i know folk probably dont like asda but they sell B complex vits including b12 for 47p!
you can also get selenium plus a,c & e vits for 47p too.
Tgirl, I've never seen nutritional yeast flakes with b12 on sell in the UK.Quote:

I don't trust nutritional yeast as a valid form of B12 unless it says so right on the package (afaik, Red Star Vegetarian Support Formula has B12 in it and I'm not sure about the others). I've read too many stories about people that have trusted nutritional yeast for their B12, only to later develop signs of deficiency without knowing why.
My B12 is kept in the refridgerator. It not only keeps it cool so it doesn't go off or alter in any way, it's also the only place I've found that I can keep my supplements and not forget to take them. :)
The brand I'm taking now isn't suitable for vegans, but after this bottle is done with I plan on buying B12 sublinguals.
I just get B12 from the margarine, soya milk and breakfast cereals I use.
In the wee jar with the gold label, I found those this weekend.Quote:
