WHAT IS THE FUSS OVER VITAMIN B12
Why many are Vitamin B12 Deficient?
You will often see patients take especially the elderly patient when there’s absorption issues, they may not be getting they may often be b12, to start of B12 is a water-soluble vitamin that your body needs to function.
Now what does b12 do actually in the body it: Helps with red blood cell formation brain health cell metabolism DNA synthesis your function does a lot and really important things now where does b12 come from your body does not make B 12 and so you have to get it from external sources many people they usually get it in their diet unless there’s some kind of absorption issue in their intestine’s animal sources are usually the commonplace fortified foods and also supplements b12 is it’s it can be stored in the body mainly in the liver and per Merck manual your body can actually store roughly between three to five years before it’s exhausted now where does b12 come from mean actually in foods so let’s talk about some foods that actually have b12.
B12 is generally found in animal products such as organ meats clams sardines beef tuna salmon milk. Milk and dairy products eggs.
Yet a lot of people aren’t familiar with what that is it kind of has almost like a cheese flavouring to it but it’s like flakes and you spread it on whatever kind of food you like and it has a very savoury taste. The recommended amount goes up as adults it’s usually 2.4 my grams and that doesn’t sound like much especially when you can compare it to the doses and over-the-counter supplement this may seem like a big dose but what you have to remember then let me say a thousand micrograms you may hardly absorb any of that so that’s why a lot of times, they’ll highlight that what are the different ways to take b12.
There are a lot of different ways to take b12 one of my favourate ways to take is sublingual that I was taught for years. That helps if you there is any kind of digestive disorders. There’s numbness and tingling fatigue a lot of times, they will get I am or subcutaneous injections now I like this quote because this exists existing evidence does not.
Suggest any differences among forms with respect to absorption or bioavailability however the body’s ability to absorb vitamin b12 from dietary supplements is largely limited by the capacity of the intrinsic factor for example only about 10 micrograms of a 500-microgram oral supplement are actually absorbed and healthy people I have seen some different facts about that and so definitely that may vary a bit but just the biggest I think the takeaway point from that is; knowing that only a small percentage is really actually absorbed how is it best absorbed now there’s some different views on this and as mentioned before studies are showing that there’s really not much of a difference personally.
At risk for vitamin B deficiency but intestinal malabsorption is one of the biggest reasons for vitamin b12 deficiency and it’s not usually due to a lack of b12 in a person’s diet. Following is a list that of different things increases the risk for vitamin b12 deficiency vegans’, vegetarians’ gastric surgery patients’ pernicious anaemia older patients with the atrophic gastritis and stomach so disorders like such as Chrome select disease.
So lets go over the top four that you see here on the list and just talk a little bit briefly about them so earlier. We did talk about how malabsorption is one of the biggest reasons for vitamin b12 deficiencies but there are sometimes dietary reasons why there would be a vitamin b12 deficienc. Typically I’m talking about vegans and vegetarians since vegans are not eating animal products they rely on supplements and also try to get it from nutritional yeast as explained.
Astrid bypass patients if there’s any kind of bowel resection where the receptors for the intrinsic factor and the b12 complex are located if any of that has been disrupted then a lot of times, they’ll be issues with the absorption. Pernicious anaemia this is an autoimmune disease that can cause lack a protein called can’t risk factor which is basically what helps the b12 get absorbed and then trinsic factor is Produced by the stomach and it basically binds the b12 in the stomach and helps with absorption in the small intestines and people who have this disease often have difficult times absorbing the b12.
They’re often low and b12 levels and they often find themselves with decreased red blood cell production and these individuals usually benefit from b12 injections next question can you get too much b12 there been there hadn’t really been any toxic or major adverse effects from large beetle intake.
Some of this is due to the probably to the fact that individuals taking B12 orally they only absorb a small percentage of the b12 so that may be why so there’s little potential for toxicity generally the body takes what it needs and the excess is extremely urine or stored in the liver.
The final question is drugs interact with vitamin b12 yes there are some drugs that can actually decrease the absorption of b12.
Specifically, any kind of drug that you can think of it this way any kind of drugs that affect the acid in the stomach. So if you Vitamin B12 deficient or believe you maybe seek council from your doctor and supplement with a quality Vitamin B12 supplement.
