Do you feel B12 shots right away
Individuals looking to increase their B12 levels may be wondering, “How quickly does a B12 shot work?” Ultimately, this can depend on a number of factors such as your B12 intake and how effectively your body can process B12. Before we give you a possible time frame to expect your B12 shot to work, consider your relationship with B12.
- Do you intake enough B12? Does your body actually use the B12 you supply it with? B12 Intake Vitamin B12 is largely supposed to be ingested through your daily diet.
- In an ideal situation, as your body uses B12, you are replenishing your B12 levels by eating foods that contain the vitamin.
- In other words, you get more B12 at the same rate you use it.
This isn’t practical for individuals who suffer from chronic B12 deficiency or frequently deplete the entirety of their B12 stores. The daily intake of B12 isn’t able to keep up with B12 the body is using. One solution is to give your body a larger dose of B12 all at once.
B12 shots provide a concentrated dose of B12 directly to the bloodstream. For someone who has difficulty in taking B12 due to underlying health conditions or diet, this helps offset the need for daily small increments of B12. B12 Absorption Because we get B12 through our diet, the absorption process happens during digestion.
However, many factors can impact our absorption, either limiting it or preventing it altogether. This usually occurs in individuals with underlying digestive conditions, who have trouble absorbing all nutrients through digestion, or pernicious anemia which specifically prevents B12 absorption.
- When your body does absorb B12, it then takes time for the vitamin to be distributed throughout the body and more time for the body to use it in a way that is noticeable.
- This is why patients with low B12 levels can be prescribed B12 shots instead of supplements.
- B12 shots bypass the digestive process as they are administered through the bloodstream.
The bloodstream acts as the body’s delivery system, so the B12 is able to be delivered that much faster and can immediately start being used by the body. The Short Answer So really, how quickly does a B12 shot work? Most patients report feeling the effects of a B12 shot anywhere from 12-48 hours,
- Imagine how much longer that would be if you still had to ingest, break down, and absorb the B12 before the 12-48 hour time period started.
- Some patients, usually those with chronically low levels of B12, may notice results faster than this, but this could also be attributed to the power of positive thinking or the placebo effect.
Other patients may notice less extreme results that indicate your B12 levels were already near the healthy target. If you’re scheduling a B12 shot and have a certain time where you want to be sure the shot has taken effect, such as finals week or before a big event like a wedding, aim for an appointment one to two days before the date in question.
This will give your body all the time it needs to effectively utilize the B12. Healthy B12 levels rely entirely on effective B12 intake and absorption. For individuals who have difficulty eating foods that provide their body with enough B12, a B12 shot is an alternative that won’t compromise your other dietary needs.
If the issue lies with absorption, B12 shots are administered through the bloodstream, meaning they do not need to be absorbed through the digestive process. Depending on your B12 levels at the time you receive a B12 shot, expect to see results anywhere from 12-48 hours.

- Davis, who has studied B12 for over 50 years.
- A study in the journal Mayo Clinic Proceedings ( 1 ) sheds light on some of the potential benefits of B12 injections for people with a deficiency.
- Researchers shared that one 55-year-old woman who struggled with depression and symptoms such as numbness in her feet saw her symptoms gradually lessen within three to four weeks of getting B12 shots.
A 17-year-old saw symptoms such as fatigue, dizziness, and nausea she’d battled for two years either reduce considerably—some even vanished.

Therefore, vitamin B12 deficiency may lead to decreased serotonin production, which can cause a depressed mood. One older study in people with depression and vitamin B12 levels on the low side of normal found that those who received both antidepressants and vitamin B12 were more likely to show improved depressive symptoms, compared to those treated with antidepressants alone ( 21 ).
In a large review, researchers discovered that vitamin B12 deficiency was associated with a higher risk of depression, but only in older females ( 22 ) Though vitamin B12 supplements may help improve mood and depression in people with a deficiency, research does not currently suggest that they have the same effect in those with normal B12 levels ( 23 ).

How fast does B12 shot take effect?
B12 injections work quickly; they are the most effective way for your body to absorb Vitamin B12. Within 48 to 72 hours, your body will begin to make new red blood cells. For mild deficiencies, you may need two to three injections over several weeks to notice peak impact.
How long does it take for B12 to hit your system?
Treatment – Treatment for this condition involves replacing the missing vitamin B 12, People who cannot absorb B 12 need regular injections. When injections first are administered, a patient with severe symptoms may receive five to seven during the first week to restore the body’s reserves of this nutrient.
- A response usually is seen within 48 to 72 hours, with brisk production of new red blood cells.
- Once B 12 reserves reach normal levels, injections of vitamin B 12 will be needed every one to three months to prevent symptoms from returning.
- People who cannot absorb vitamin B 12 should continue to eat a well-balanced diet that provides other nutrients ( folic acid, iron and vitamin C) necessary to produce healthy blood cells.
Sometimes people can take high doses of oral B 12 to provide replacement instead of undergoing injections, but a physician should closely supervise this. In people whose vitamin B 12 deficiency is related to overgrowth of intestinal bacteria, treatment with oral antibiotics, such as tetracycline (sold under several brand names), may stop bacterial overgrowth and allow the absorption of vitamin B 12 to return to normal.
Do B12 shots work faster than pills
Shots of vitamin B12 are often given in doses of 1,000 mcg/mL, while vitamin B12 pills often come in capsules, tablets, or soft gels of 50 to 5,000 mcg. But you can’t just make B12 pills equal the dosage of a B12 shot. Vitamin B12 is essential for keeping your central nervous system healthy, making red blood cells, and creating DNA.
(Kind of a big deal!) And if you have a deficiency, taking B12 pills or getting a B12 shot are both legit ways to up those B12 levels. Here are the dosages you can expect from different B12 options. While it might seem like a 1000 micrograms (mcg) B12 shot is equal to a 1,000 mcg B12 supplement, it’s not that simple.
Your body absorbs these B12 formulations differently, so you can’t simply make B12 pills equal a shot dosage. How often you take B12 pills and get B12 shots also differs. For B12 deficiency, a typical injection dose is 1,000 mcg once a week for 4 to 8 weeks and then 1,000 mcg once a month.
But dosages can vary depending on if you’re treating severe, mild, or asymptomatic B12 deficiency. For vitamin B12 pills, most people take these daily in doses recommended by their doc but taking 1,000 mcg daily is pretty standard. However, an oral B12 dose is often larger because your body usually doesn’t absorb it all.
According to 2008 research, your body only absorbs about 1.3 percent of a 1,000 mcg oral dose and 2 percent of a 500 mcg oral dose. The same study found injection absorption rates were about 55 to 97 percent, B12 injections are intramuscular shots (meaning they go into the muscle), which are absorbed rapidly because of the great blood supply in the muscle.
Taking B12 supplements can be an effective way to treat B12 deficiencies and isn’t necessarily inferior to B12 shots. If you’re deficient, your doc may recommend you take about 1,000 to 2,000 mcg of vitamin B12. In a 2018 review, researchers found evidence that taking 1,000 mcg of B12 and getting B12 injections had similar effects on treating B12 deficiencies.
But the studies included were small and only lasted about 3 to 4 months. The type of B12 supplement might matter too. A 2019 study found sublingual B12 supplements (aka the kind you put under your tongue) were even more effective than B12 shots. Older research also supports that taking 1,000 to 2,000 mcg of B12 is likely just as effective in treating deficiencies as injections.
You can totally take B12 pills instead of injections if your doc gives you the A-OK! Only people with vitamin B12 deficiencies should take oral B12 supplements (that’s about 6 percent of the US population under age 60). Even though you can find B12 in supplement aisles, you really need to make sure you’re actually deficient before taking B12 supps.
Taking B12 capsules when you’re not deficient can lead to side effects, have virtually no benefits, and just be a waste of $$$. Based on the research we have so far (from 2005 and 2018 ) it looks like supplements are pretty effective at normalizing B12 levels at doses of 1,000 to 2,000 mcg.
- But you’ll want to work with a pro to come up with a plan.
- You need to go to a doctor to get a prescription for B12 injections.
- Typically, a healthcare professional will inject them for you, but you can also sometimes do them at home.
- Talk with a pro to figure out what’s right for you.
- B12 shots are made from hydroxocobalamin or cyanocobalamin, manufactured forms of vitamin B12.
They’re intramuscular injections, which means they’re injected into the muscles — typically in your arm or thigh. With the shot, the B12 is absorbed rapidly thanks to the blood supply in the muscle and you should experience benefits right away, Within a couple of days, you might start to see your symptoms improve and feel better.
But B12 injections aren’t just a one-and-done thing. You’ll usually start getting injections at least a few times a week. Then, your dose may change based on your doc’s orders and how you respond to treatment. As your symptoms improve, you might only need them every couple of months. If you’re heading to the doctor to get a B12 shot, there’s no need to prepare.
Before you get one, you’ll discuss the process and your history of meds and allergies to make sure you’re good to go. If you’re giving yourself the shot at home, your doc will tell you how to prep and administer it. You’ll need to:
Clean the injection area with rubbing alcohol.Administer the injection into the muscle (the thigh is typically easiest if you’re doing it yourself).Dispose of the needle properly (in a sharps container, and not in your regular garbage — return it to the doc’s office or a biohazard collection site!)
After the B12 shot is injected into your upper arm, thigh, hip, or butt, you should experience benefits right away. After the shot, many people experience side effects like pain, itching, and swelling. But these effects should go away pretty quickly. When you first start getting the shots, your doc will prob prescribe an injection at least a few times a week,
Your dose may change depending on how you respond to the treatment and the vitamin B12 levels in your blood. As your symptoms improve, you might only need them every few months or so. Both B12 shots and pills have pros and cons. So, when picking between them, it really comes down to your preferences and what your doc recommends.
Here are the main differences:
Cost and convenience. B12 pills are much cheaper than injections. You can get a bottle of 100 for under $10, at just 10 cents a serving. Meanwhile, one injection of B12 will vary widely based on health insurance but can easily be more than $50. You’ll also need to make an appt, get bloodwork done, and get a prescription from your doc. Absorption. B12 injections are absorbed straight into your bloodstream, making them faster-acting and potentially more effective. Though the science hasn’t proven how effective the pills are for sure yet, experts *do* know that injections really work — and fast. Also, keep in mind that under-the-tongue supps may be more effective. Mode of application. Some people are needle-phobic — others hate remembering to take pills every day. Ultimately, the choice is up to you (and your doc).
B12 injections might not be ideal if you :
have had an allergic reaction to hydroxocobalamin or any other meds in the pasthave low levels of potassium have an irregular or rapid heartbeat
Again, don’t just start taking B12 if you don’t know you’re deficient. Signs of a B12 deficiency include :
paintinglingdifficulty walkinguncontrollable muscle movementsconfusion, forgetfulness, or memory losschanges in mental state or moodchanges in smell or tastevision problemsdiarrheaweight lossglossitis, aka a painful, smooth, and red tongue
If you have any of the above symptoms, talk with a doc. Both B12 vitamins and injections can help treat a B12 deficiency, although your body will absorb injections much quicker and more easily. We need more evidence to know if the pills are as effective as the shots over time, though some research suggests they work, especially when it comes to sublingual supps.
