The B12 in supplements is made from bacteria and sourced from bacteria cultures. It is not from animal products. However, some supplements can contain gelatin in the capsule, which you should look out for. Streptomyces griseus, a bacterium once thought to be a yeast, was the commercial source of vitamin B12 for many years (8, 9). The bacteria ...

Artificial vitamin B12, also known as Cyanocobalamin is produced by bacterial fermentation, as indicated here. Technically, bacteria are far from being considered animals, so this method should be vegan-safe: Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other ...

They are essentially the same molecule, but for one bond: cyanocobalamin has a CN- (cyanide) tied to the cobalt atom, while methylcobalamin has a CH3- (methyl). There are also adenosylcobalamin (also called 5-deoxyadenosylcobalamin, C10H12N5O4-, adenosine) and hydroxocobalamin (OH-, hydroxyl). While the latter should be more soluble in water, the amount ...

The vegan society states the following: In choosing to use fortified foods or B12 supplements, vegans are taking their B12 from the same source as every other animal on the planet - micro-organisms - without causing suffering to any sentient being or causing environmental damage. Now, it's up to every person to decide for themselves whether or not they ...

From the Vegan Society: To get the full benefit of a vegan diet, vegans should do one of the following: Eat fortified foods two or three times a day to get at least three micrograms (mcg or µg) of B12 a day OR Take one B12 supplement daily providing at least 10 micrograms OR Take a weekly B12 supplement providing at least 2000 ...

I'm not a doctor or another health professional, this is what I remember from my research when starting to take B12. The most important thing is to take them regularly. B12 builds over time and is stored in the body (mainly the liver), so if your body needs some in the morning but you take your supplement at night, it will just take what it needs from its ...

Vegan omega 3 supplements are widely available. In the UK they can be found in any "health food" type store, for example. Typically these supplements are flaxseed oil or linseed oil in non-gelatine capsules. You can also use liquid flaxseed/linseed oil. You get a much higher dose from a teaspoon of oil than a capsule. I find the flavour quite vile, so when ...

Vitamin D is often treated generically, sometimes even not specifying the index. According to this article, there are five Ds (D1, D2, D3, D4 & D5) and only D2 (ergocalciferol) and D3 (cholecalciferol) can be used by our bodies. This article goes further and makes a difference between D2 and D3. D3 is clear winner (my emphasis): The majority of ...

No, iron supplementation is not necessary for all vegans. Furthermore, iron supplementation can be dangerous if it isn't a medical requirement. Any person considering adding iron supplements to their diet should have a conversation with their doctor or a registered dietitian to assess their individual needs and the safety of a particular supplement. The ...

The answer to the question would be largely the same as for identifying vegan anything. First, look for the vegan label on the package. Usually this is either a nice green V, even nicer animal picture or, as Zanna suggested, this logo. Make sure this does not mean Suitable for vegetarians as this still may (and probably will) not be vegan. If you could ...

If you're just buying at the supermarket, you really can't know. There are lots of hidden animal products, especially in supplements. My advice would be to purchase them online from an all vegan website. That way you'll know they're vegan. Otherwise make sure the supplement specifically says vegan on it.

One basic thing to know is that B12 supplement absorption rate decrease with the total amount of B12 provided by the supplement (check here). In other words if you get your supplement daily then 1-2 mcg could be enough, but if you get it weekly it would be necessary to intake as much as 1000-2000 mcg. The "standard" dose is 1000-2000 mcg per week, since is ...

I hope you've read the closely related answer (here). Intensive sport training, and therefore weightlifting, demands higher levels of nutrient intake. The nutrient that is most likely to be insufficient in people doing such kinds of training is - as you pointed out - iron. The first thing an athlete has to do is to periodically check the blood status, and ...

As you said, B12 is highly soluble in water and unused quantity is easily excreted from the body as urine. Therefore, it is nearly impossible to get an overdose of B12, even if you exceed the recommended daily intake. However, the component which possibly have a very small risk is cyanocobalamin because it releases a tiny amount of cyanide within the body ...

Nordic Naturals algae oil gelcaps are vegan. Many assume that omega-3s have to come from fish oil. That is why we created Algae Omega. Nordic Naturals Algae Omega is the ideal vegetarian alternative to fish oil. This omega softgel is certified vegetarian by the American Vegetarian Association. It is also suitable for vegans. It is made from microalgae, ...

I found one study that addresses the production of Vitamin D3: Life cycle assessment of vitamin D3 synthesis: from batch to photo-high p,T (Springer Link HTML, data table HTML, DOI). The functional unit of analysis is 1,000 mg crystalline vitamin D3. In terms of dosage, 1000 mg of crystalline D3 is equivalent to 40,000,000 IU. Assuming a daily dose of 1000 ...

It is basically because we no longer drink untreated water and we no longer eat fruits and vegetables without washing them. B12 is produced by a bacteria in the soil. It is hard to absorb 1 month worth of B12 in a single dosis

In order to prevent thrombosis, what supplements should vegans take? Thrombosis is defined as: The formation or presence of a blood clot in a blood vessel. If you are worried that you may be at risk of thrombosis you should see your doctor straight away.

While vegetarianism is a consideration in testing for B12 deficiency (as you are at higher risk). B12 supplementation is usually advised based on monitoring levels in the blood rather than your demographics. B12 is a stored vitamin so it may take a long time (months to years) to develop a deficiency. Therefore you are advised to take more than your body ...

This kind of questions will always be a bit subjective but I believe one can call themselves vegan if they are doing as much as possible* to avoid animal abuse. For instance, I wouldn't judge for not refusing a pig heart valve to fix your faulty heart valve, but some vegans might. On the other hand, vegan omega 3/6/9 pills do exist and they might be ...

There are a lot of interesting questions you pose and some are addressed in the article Do carnivores need Vitamin B12 supplements?. Let's first look at the claim that vegetarianism must be unhealthy because they need to supplement B12. According to the excerpt below, it appears that both meat eaters and vegetarians are equally deficient in B12. The ...

I would like please to know from experienced vegetarians if you take any supplements or not and which ones if any I've lost count how long ago it was that I transitioned to vegetarianism. I transitioned in a similar way to the way you're currently doing, and that's by reducing the amount of meat I was eating till it was virtually none, then completely ...

Heart attacks and strokes are caused by eating too much oil. The link between high cholesterol and heart disease was made clear in this study done in the 1950s. Note that this was long before the time statins were invented. Two populations living in Uganda were compared, the indigenous Africans had a low cholesterol while the Asians had a high cholesterol. ...

Dr. John A. McDougall himself recommends: If you follow the McDougall Diet for more than 3 years, or if you are pregnant or nursing, then take a minimum of 5 micrograms of supplemental vitamin B12 each day. As for human adaptation to availability of B12, you need to consider sources other than meat eating. For example... Feces of cows, chickens, sheep ...

B12 is a stored vitamin. You can take high doses on a less regular basis and doctors do prescribe injections of vitamin B12 for patients with severe deficiency. Most vegans aren’t severely deficient, they’re at a high risk of deficiency without dietary supplements. Bioavailability and absorption are the main reasons for this recommendation. It’s better to ...

I have been a vegetarian for over 50 years and a vegan for much of that time and have never taken any supplements of any kind. So, in my case, I can safely say the answer is "No!" However the plural of anecdote is not data and things may be different for you.

While a person on a mixed (animal/plant) diet, even the one who has really bad eating habits (unregular meals, a lot of junk food), rarely needs to worry how to get enough iron, vegans should counsciosly think to consume enough iron-rich foods. However, iron supplements are needed only in case of proven deficiency. Plant foods high in iron (USDA.gov): ...
