Vitamin B12

Best answer to the one who explains this to me in the best detail and shows their sources.

A: How vegans obtain vitamin B12:

-Drinking fortified soy milk- Probably the easiest way to top up your b12 levels. Most popular brands of soy milk, such as Alpro Soya, have vitamin B12 added. I like Aplro Soya products- the website is below:

-Another way of obtaining vitamin B12 is eating fortified breakfast cereals.

-Incorporate nutritional yeast into your diet (you can sprinkle it on soups, porridge, etc)

-It is recommended that vegans supplement this vitamin, as plant based sources (such as seaweed/ unwashed vegetables) are not reliable sources, supplements help protect against any dietary deficiencies. Vitamin B12 is found naturally in animal foods, particularly cow’s milk.
B12 is mportant for cognitive function & nerve health. The first signs of deficiency is lack of energy. It is a vitamin that is stored in the liver in large amounts. If you go a day without an intake of B12 from the diet, your liver will take what it needs out of storage. It is the *only* B vitamin that is stored in the body, the rest of the B vitamins are water soluble.

”Vegans are recommended to ensure their diet includes foods fortified with vitamin B12. A range of B12 fortified foods are available. These include yeast extracts, Vecon vegetable stock, veggieburger mixes, textured vegetable protein, soya milks, vegetable and sunflower margarines, and breakfast cereals”.
-A quote from The Vegetarian Society- it has some info on vegan nutrition.

I suggest that you top up your B12 levels each day by eating some of the foods named above. A lack of B12 can cause a form of anemia (spelt anaemia in the UK!). Pernicious anemia is a form of megaloblastic anemia. Symptoms of B12 deficiency include weight loss, loss of appetite, pallor & fatigue, although there are a number of symptoms. There are many anemias, but iron deficiency is the most common nutritional deficiency in the western world.

Q: vitamin B12?
Where do you get vitamin B12 from is it in food form or tablets

A: Vitamin B is a complex vitamin and is available in many foods, but is also available in medical formulations

Q: Vitamin B12…?
As a vegan, I was wondering if I only consumed fish as my vitamin B12 source, once a week, would I still meet the requirements of B12 intake? I know that the B vitamins are water soluble therefore needed to be taken everyday, but I do not wish to consume meat and ordairy products on a daily basis.

A: if u did consume the fish u wouldnt b a vegan, lol
take some b12 supplement vitamins instead
though alot of vegerterian products have b12 in them, like vege hotdogs ect xxxxxxx

Q: vitamin b12?
how important is it? im a vegan and i used to take a supplement. but then i relized if b12 is only found in meat then they probley produced the supplement from the meat, haha

can anybody give me some advice on b12?
how can i find vegan sources of vitamin b12?
i understand what happens with b12 deficiancy or w.e… but can vegans offer some advice on where they get there source?

A: B12 might be found not only in animal food, which is wildly mistakenly believed. B12 found in a lot of algae as spirulina, Chlorella.
As for drinks plenty of B12 contains in Kombucha, wonder drink that tasted awesome and one can do himself at home.

PS: Wikipedia definitely has a mistakes if you looks for B12, they say this vitamin can be found only in animals but at the same time if you look up Chlorella, Spirulina or Kombucha it DOES confirm they all have B12 and its not from animals

Q: What is the difference between Vitamin B12 and B Complex?
What is the difference between Vitamin B12 & B complex? Do I need both?? I’m looking at the bottle of my B Complex and it doesn’t list B12 but it lists B6. Should I take both a vitamin b12 and b complex every day? I’m a vegetarian woman and heard that Vitamin b12 is good to prevent anemia. I also take iron supplements.

A: yes you can take both but watch the b12 intake and take as directed..b12 if you take to much becomes a poison in the body due to the body cant release it in urine like most vitamin supplements

Q: How long does it take for B12 vitamin to work?
I just got the vitamin B12 supplement because I heard it helps with migraines (which I desperately need help with!) But how long should it take to work? I tend to get migraines rather often.

A: I haven’t heard about B12 helping with migraines, but I have a feeling the supplement in pill form may not help you very much. Not everyone is able to absorb B12 well when taken orally. Some, like my husband, seem to, though. If you believe it might work you might want to talk to your dr. about B12 in injection form. It’s easy to give yourself.

Something you might want to consider for migraines (that seemed to help me) is high doses of Vit. C. If your migraines are caffeine triggered (or caffeine withdrawl triggered) it’s a difficult balancing act to work up to a high enough dose of Vit. C while working your way down the caffeine ladder.

I want to specify that I am NOT a doctor, and that any of this stuff needs to be checked out with your doctor before you do it. I am just speaking from my personal experience.

Q: What is the maximum amount of vitamin B12 that a person can take daily?
I know I should see a doctor but I can’t afford it right now. I have burning feet at night and they’re usually sweaty during the day. I also don’t feel like my circulation is right. I don’t know if an irregular heart beat could be because of this. I’m very fatigued and never feel good. I heard that I might need vitamin B12 so I wanted to try that to see if there is a difference.

A: Hello,

I’m sorry about this.

Vitamin B12 is not always absorbed from the ’stomach’ very well. There is nothing wrong with getting them to try, but if you are low on Vitamin B12 (as proved by a blood test), a doctor would certainly want to treat you by giving you Vitamin B12 Injections.

Low Vitamin B12 is associated with damage to the nerves going to the legs, technically called ‘peripheral neuritis.’ It’s usually just one part of a disease called ‘Pernicious Anemia,’ (I’m sorry, there is no common name).

Pernicious Anemia is quite a serous disease. It mostly affects older people, you don’t say how old you are.

It might be low B12 like you say, but I don’t think that would be causing the irregular heart beat or the circulation problem.

You can try B12, like I say, but I don’t quite see how you’re going to get this fixed without a few blood tests and a medical opinion.

I hope this is of some help.

Best wishes,

Q: How should I supplement my diet with vitamin b12?
I am a partial vegetarian. I only eat seafood, no red meat or poultry. I do eat dairy products as well. After watching a show dealing with b12 deficiencies, I think I may have that problem. Before going to the doctor which I cannot afford I would like to try to supplement my diet with b12 to see if that helps. I do not want to overdose on b12 so how should I do this? Should I do vitamin pills or adition to my diet?

A: Ah, so you’re Pescetarian? That’s cool….as a vegetarian, I simply get enough b12 from eating plenty of Dark Green Veggies such as; Broccoli and Spinach. Check out my link below and scroll down on that page, it talks more about getting enough vitamins and minerals and what-not.

Q: How does vitamin B12 help lower my heart rate?
Does it lower homocysteine levels in my blood? I used to have tachycardia. Now since the doctor tested my blood, it was determined that i was low in vitamin b12. So ive been taking vitamin b12 for sometime now, and I don’t experience increased heart rate anymore. I feel better.

A: Folic acid (folate) and B12 vitamin help break down homocysteine, an amino acid in your blood.

V B 12 deficiency lead to anemia and anemia lead to tachycardia(increase of heart rate).

So, with usage of V B12 and treatment anemia, heart rate come down, under these circumstance vitamin B12 can decreases a fast heart rate.

Q: How low does ones vitamin B12 need to be to reach Anemia?
I have really low vitamin B12. My blood test result sheet says B12 should be between 165 – 829. My doctors said good levels to have are between 400 – 600, I have only 79. For some reason I never faint or rarely get dizzy, especially during exercise. My red blood cells are also perfectly fine.

Is this abnormal? Specifying age groups with levels would be a much appreciated answer.

A: Well, I can give you what I know. It may not directly answer what you asked, but hopefully it can shed some light on things you may not have mentioned. The amount of B12 a person needs varies. The average adult is said to need 2.4 micrograms of B12 every day. Age is only one factor in why you may need much more than that. You can’t overdose, so I would try to do a super booster.

Hear are some other symptoms that can mean a lack of B12. You may not be anemic, but that doesn’t mean you aren’t suffering from the low levels in other ways. If you have any of these symptoms, but especially if you have more than one, you would benefit from taking B12. You can take subcutaneous tablets (they are placed under your tongue and absorb directly into the blood stream) or you can opt for B12 shots. Has your doctor suggested the shots? It would seem that you are a huge candidate for them with such low levels.

Possible symptoms of low levels of B12:
diarrhea, low levels of energy, no energy, loss of appetite, shortness of breath, fatigue, tingling of the hands and feet, numbness, depression, confusion, soreness of the moth and tongue and, of course, anemia

I truly hope I have been helpful.

Q: Do vitamin b12 supplements work?
Does your body absorb vitamin b12 as well from supplements or fortified foods as well as it does from meat?
Jonah – Thank you that is very helpful – but what about fortified foods, since they are broken down in the intestine, would they provide as good a source of vitamin b12 as meat do you think?

A: As per a study by the USDA, supplements are the most effective way (for Everyone) to get b12. Second to that, fortification and dairy.

“The good news,” said ARS* administrator Floyd Horn, “is that most people can improve their B12 status by eating more fortified cereals and dairy products. Dr. Tucker’s findings show that these foods were nearly as effective as supplements containing B12 for getting people’s blood levels above the danger zone.”

“Oddly, the researchers found no association between plasma B12 levels and meat, poultry, and fish intake, even though these foods supply the bulk of B12 in the diet. “It’s not because people aren’t eating enough meat,” Tucker said. “The vitamin isn’t getting absorbed.” “

* Agricultural Research Service (ARS), USDA’s chief scientific agency.

USDA aside, from my experiences, the fortification is plenty. My doctor had the typical ‘you need to eat animal products’ mindset and said I had to be taking a supplement. I said I thought I was fine, but figured they were a doctor, so I took one anyway…shortly after, I had my blood drawn and my levels were Very high…at which point, the doc said ..oh…well…don’t take the supplement..

As for it making more sense to just eat animal products – we give cows cobalt (which they need to make b12), we give pigs & chickens b12…in other words, we either fortify their food and then eat them…or just eat the fortified food directly. Between the two, the latter makes far more sense to me.

Q: What is the percent composition of all the elements in vitamin B12?
What is the percent composition of all the elements in vitamin B12 (C63H88CoN14O14P)?
Report answer to the proper number of significant figures.

Chemistry teacher didn’t explain this very well and I don’t really get it. Help would be appreciated thank you!

A: Molar mass of cyanocobalamin B12 is 1355
So % compositions
C = 756/1355 x100 = 55.8%
H = 88/1355 x100 = 6.5 %
Co = 59/1355 x100 = 4.4 %
N = 14.5 %
O = 16.53 %
P = 2.3 %

The Molar mass is taken from wiki

Q: What is a safe amount of iron and vitamin b12 to take when pregnant?
I’m 17 weeks pregnant and want to see if taking an iron and vitamin b12 supplement will make me feel a little better. I’ve tried taking things like pregnacare, but they make me sick so I figure I may be better off taking supplements.

What is a safe amount of each of these for me to take?

Thanks in advance!

A: Your doctor is the best person to advise you, but I know that B6 is much more important than B12 during pregnancy. My doctor told me to take 100mg of B6 twice daily.

Q: How do people in India get their daily recommendation of Vitamin B12?
There is a lot of discussion and research on the ‘net about vitamin B12 deficiency in Vegans. By far the majority of people in India are vegetarians. How are they able to get enough B12 in their diet?

A: B12 is found in all meat products including dairy & eggs. Indians eat a lot of dairy in the form of milk & yogurt & so will be able to get Vit. B12 from that. Also, the human body recycles it’s Vit. B12 & so if you got absolutely no Vit. B12 in your diet, it would take about 12 years to get a Vit. B12 deficiency.
