Within 4 to 6 days of receiving a B12 injection, most people experience an increase in their energy level or stamina.

Lots of rubbish answers here, sorry Mr/Mrs Asker.\n\nIf the answerers actually read the question - the asker isn't looking for what to do normally to keep his health in check - but wants to know what to do on the occasions it goes a bit AWOL, as happens to all of us now and again.\n\nI'm type 1, so can't help you here (it seems a lot easier to deal with short term probs like this when you're on injections), but it seems you'll be better off speaking to your doc as people don't seem to be able or willing to answer.

Hi there.. I'm a Licenced Dietetic Technician. The answer to your question....Anemia is a concern that can be fixed. Anemia is a condition in which the iron count in your blood is low meaning you have a hard time transmitting oxygen in the blood to other body parts. An easy solution is to take a simle daily supplement of 18mg/daily for 2 weeks. Then have your HGB and HCT checked again to see if the Anemia has improved. Make sure you also take a Vit C supplement with the Iron to help absorb the iron. Hope this helped. Your should have more energy because you'll have more oxygen flowing through your blood! Good luck and if you have anymore health questions feel free to ask. -Elizabeth Segler DTR/LDT

You should start feeling better real soon. I had mine done a few years ago. It took about 5 days to feel better. But call your doctor if you have concerns.

Your body is not used to most of the vitamins and minerals.  It may take you s few days to a week to start or stop feeling the effects of them, depending on why you are taking them.

Vitamin B12 is required to maintain healthy nerve and red blood cells. I believe it is associated with proteins, since it is usually found in most meat. The recommended daily allowance for the amount of B12 one should be taking is too miniscule to list, since you should take in about 2 micrograms everyday. For the most part, people take in enough to fill their needs. And there are no extreme side effects that I know of in regards to taking in more than the daily allowance. Unless you're a vegetarian, I wouldn't worry about having a deficiency of B12. You could do without those pills and invest your money elsewhere. \n\n*I apologize for failing to mention some tips to speed up your metabolism. The more times you eat a day, the more your metabolism will accelerate. Be sure to control those portions, though. Another big factor into a fast metabolism is muscle. Lifting weights 3 days a week will help tremendously in boosting your metabolism. I hope this helps.

Soo many good supliments out there. \nB-12 (cyanocobalamin) in food is an extrinsic factor, meaning there is B-12 intrinsic factor, located in the stomach, neccessary to make this vitamin usable.\nThat said, I stay away from the subligual B-12 suppliments. They get B-12 into the bloodstream without the need of intrinsic factor, and the body often stops producing what it doesn't need. I haven't heard of this ever having happened with sublingual supplimentation, probably because it would take a while for this to happen, not the usuall couple of months that people usually would try "megadosing" on B-12 with sublingual lounzes. (The need for intrinsic factor limits the amount of B-12 that can be absorbed by the stomach, the average person has enough intrinsic factor to absorb about an 80% RDA B-12 actually). \nLong term vegitarians who don't get B-12 eventially stop producing the intrinsic factor, and then they end up needing B-12 shots for the rest of thier lives, but this is the one and only water soluble vitamin that the body stores, if I remember right, shots are given every 6 months.\nAll that said, of the numerous things I use, Odwalla B Monsters are a tasty source, (I just drank a half). You can drink half, put the other half in the fridge to drink later in the day, and that way have well over your 100% RDA. \nMultivitamins usually have at least 100% RDA, and are cheaper to stock up on than Odwallas, but it might be better to get vitamins from food than pills. A lot of artificial meat on the market is also B-12 fortified, check out the nutritional labels.

Take a multi vitamin I have the same problem but when I remember to take my vitamins in the AM I don't yawn or feel as tired after eating. You  can also  try taking a short walk after you eat to get the digestion working a lil faster.

Functions\nVitamin B12's primary functions are in the formation of red blood cells and the maintenence of a healthy nervous system. B12 is necessary for the rapid synthesis of DNA during cell division. This is especially important in tissues where cells are dividing rapidly, particularly the bone marrow tissues responsible for red blood cell formation. If B12 deficiency occurs, DNA production is disrupted and abnormal cells called megaloblasts occur. This results in anaemia. Symptoms include excessive tiredness, breathlessness, listlessness, pallor, and poor resistance to infection. Other symptoms can include a smooth, sore tongue and menstrual disorders. Anaemia may also be due to folic acid deficiency, folic acid also being necessary for DNA synthesis. \nB12 is also important in maintaining the nervous system. Nerves are surrounded by an insulating fatty sheath comprised of a complex protein called myelin. B12 plays a vital role in the metabolism of fatty acids essential for the maintainence of myelin. Prolonged B12 deficiency can lead to nerve degeneration and irreversible neurological damage. \n\nWhen deficiency occurs, it is more commonly linked to a failure to effectively absorb B12 from the intestine rather than a dietary deficiency. Absorption of B12 requires the secretion from the cells lining the stomach of a glycoprotein, known as intrinsic factor. The B12-intrinsic factor complex is then absorbed in the ileum (part of the small intestine) in the presence of calcium. Certain people are unable to produce intrinsic factor and the subsequent pernicious anaemia is treated with injections of B12. \n\nVitamin B12 can be stored in small amounts by the body. Total body store is 2-5mg in adults. Around 80% of this is stored in the liver. \n\nVitamin B12 is excreted in the bile and is effectively reabsorbed. This is known as enterohepatic circulation. The amount of B12 excreted in the bile can vary from 1 to 10ug (micrograms) a day. People on diets low in B12, including vegans and some vegetarians, may be obtaining more B12 from reabsorption than from dietary sources. Reabsorption is the reason it can take over 20 years for deficiency disease to develop in people changing to diets absent in B12. In comparison, if B12 deficiency is due to a failure in absorption it can take only 3 years for deficiency disease to occur. \n\nDietary Sources\nThe only reliable unfortified sources of vitamin B12 are meat, dairy products and eggs. There has been considerable research into possible plant food sources of B12. Fermented soya products, seaweeds and algae have all been proposed as possible sources of B12. However, analysis of fermented soya products, including tempeh, miso, shoyu and tamari, found no significant B12. \nSpirulina, an algae available as a dietary supplement in tablet form, and nori, a seaweed, have both appeared to contain significant amounts of B12 after analysis. However, it is thought that this is due to the presence of compounds structurally similar to B12, known as B12 analogues. These cannot be utilised to satisfy dietary needs. Assay methods used to detect B12 are unable to differentiate between B12 and it's analogues, Analysis of possible B12 sources may give false positive results due to the presence of these analogues. \n\nResearchers have suggested that supposed B12 supplements such as spirulina may in fact increase the risk of B12 deficiency disease, as the B12 analogues can compete with B12 and inhibit metabolism. \n\nThe current nutritional consensus is that no plant foods can be relied on as a safe source of vitamin B12. \n\nBacteria present in the large intestine are able to synthesise B12. In the past, it has been thought that the B12 produced by these colonic bacteria could be absorbed and utilised by humans. However, the bacteria produce B12 too far down the intestine for absorption to occur, B12 not being absorbed through the colon lining. \n\nHuman faeces can contain significant B12. A study h

The lab values you have given are not that far off from normal.  Don't jump the gun thinking you have something majorly wrong, talk to your doc!!!

Can help, I think B complex better, but better consult the doctor, sometimes it doesn't work as you expected, because all these tabs are just helping as a supplement only, still it depend what is you main diet..

B 12 is found only in animal products.  If your vitamin B 12 is low try eating more lean meat and fish and eggs.  However, a common problem is that your digestive system may not be able to absorb the B 12 from your food.  In that case the only solution is a once a month injection.  I do my own.  It is simple, easy to do, and important because lack of B 12 in the body can be VERY serious.

Hey, I put your question on my watch list because my son is not too excited about the shots, either. Thanks for coming up with a great question - I never thought to ask it! I'm waiting to see what everybody has to say...\n\nMy advice? Remember the last time you fell on the sidewalk and skinned your knee? Or got a little sunburned? Or bumped your head hard on something? Well, getting shots hurts less and lasts for a shorter time than all of those things.  Good luck!

you must be a very happy person who likes to eat... because b12 defiency makes people have anemia and become depressed..you might be eating these foods..Vitamin B12 is naturally found in foods including meat (especially liver and shellfish), eggs, and milk products. Fortified breakfast cereals are a particularly valuable source of vitamin B12

i think you might be eating too many vitamins that may contain b12, it's only found in meats, but ask your doc i'm not quite sure but it's fat soluable so it stores in your fat cells

Vitamin 'B' Capsules! No kidding! I have bitten my tongue something horrible before, and my cheek, but when I took vitamin B, it really helped. Take 1 in the morning and one at night. you should feel a big difference the morning after you take Vitamin "b."\nVitamin World should have it, or even H-E-B.
