The length of time it takes to experience the effects of vitamin B12 varies from person to person. It usually takes between 2-4 weeks for your body to respond to vitamin B12 supplementation. Some people may experience effects as soon as 48 hours, while others may need up to eight weeks before they start to see a difference.
It also depends on the severity of your deficiency – the more pronounced the deficiency, the quicker you may experience results. In general, you should begin to experience the effects of vitamin B12 supplementation within two to four weeks.
Beyond that, you may continue to experience improved health benefits over a longer period of time as your body is better able to absorb and utilize the B12.

How long does it take to correct a B12 deficiency?
The time it takes to correct a B12 deficiency depends on a variety of factors, including the severity of the deficiency, and the type of treatment that is being used. Mild and moderate cases may take several weeks to improve, while more severe cases may take months or even years.
In general, treatment involves taking in additional B12 in the form of supplements or injections, although some people with mild deficiencies may see improvements from dietary changes alone. Results can vary significantly depending on the individual, and regular blood tests should be taken to monitor progress and make any necessary adjustments to the treatment plan.
Ultimately, the length of time it takes to correct a deficiency depends on the type of treatment and how the individual responds to it. It is important to be patient and work with a doctor or nutritionist to ensure that treatment is effective and that the deficiency is corrected as safely and quickly as possible.
Can the effects of B12 deficiency be reversed?
Yes, the effects of B12 deficiency can be reversed with proper B12 supplementation. B12 is a water-soluble vitamin, meaning it cannot be stored in the body, so regular intakes are necessary to prevent deficiency.
Typical causes of B12 deficiency include poor diet, certain medication use, gastrointestinal disorders, and vegan diets. Improving diet and taking B12 supplementation is the best way to reverse B12 deficiency.
Additionally, it is important to address the cause of the deficiency to ensure it does not recur. Those with pernicious anemia, a condition in which the body cannot absorb vitamin B12, may require regular injections of B12 to prevent and reverse deficiency.
How much vitamin B12 does it take to fix a deficiency?
The amount of vitamin B12 needed to correct a deficiency will vary depending on the individual, but most health care professionals advise a daily dose between 2. 4 to 10 mcg. If you are supplementing with B12, you should discuss with your doctor the correct dose and monitor your serum B12 levels to make sure you are taking enough to correct your deficiency.
For those with a deficiency, it is important to note that B12 must be present in the body at all times to maintain normal levels; this means that taking higher doses more sporadically is not as effective as taking smaller regular doses.
Additionally, supplementing in combination with a B-complex is recommended as B-vitamins help your body absorb B12 more efficiently.
What happens if your B12 is low for too long?
If your B12 levels are too low for too long, you may experience a wide range of symptoms, some of which are long-term. Low B12 levels can cause fatigue and make it difficult to focus. In addition, some studies have linked low B12 levels to anemia, which can make a person more prone to infections and other medical conditions.
It can also cause nerve damage due to the lack of B12 in the body, leading to issues such as numbness and tingling in the extremities. Additionally, research suggests that those with consistently low levels of B12 may be at higher risk for dementia, depression, heart disease, and diabetes.
It is important to ensure that your B12 levels are not too low for too long to avoid some of these longer-term risks. Supplementation or increasing your intake of B12-rich foods may be a way to raise your levels naturally.
However, it is best to be monitored by a healthcare professional and follow their recommendations, as too much B12 can also be harmful.
What is considered extremely low B12?
An extremely low B12 level, or severe vitamin B12 deficiency, is defined as having a serum vitamin B12 level below 140-150pg/mL. Severe vitamin B12 deficiency is considered a medical emergency and can cause a variety of neurological and other symptoms.
It can be caused by an inadequate dietary intake, pernicious anemia, or certain medications. Symptoms of severe B12 deficiency can include long-term fatigue, difficulty concentrating, depression, unsteady balance and gait, cognitive impairments, and even hallucinations.
Other symptoms can include tingling and numbness in the extremities, fast heartbeat, hair loss, weight loss, Constipation and abdominal pain, a sore tongue and mouth, and jaundice. If left untreated, severe vitamin B12 deficiency can cause permanent nerve damage and a variety of other health complications.
Treatment for severe B12 deficiency includes supplements to restore B12 levels and/or a course of B12 injections. Patients are typically monitored to ensure their levels are returning to normal.
Why is my B12 low all of a sudden?
It is not uncommon for people to experience a sudden drop in their vitamin B12 level. This can be caused by a variety of factors, including inadequate dietary intake, decreased absorption in the gastrointestinal tract, certain medications, inadequate stomach acid, and certain medical conditions.
If your B12 level is low all of a sudden, it is important to talk to your healthcare provider to determine the underlying cause.
Your healthcare provider may recommend various tests to determine the source of the low B12 levels. These may include a complete blood count, a serum B12 test, a urine test, and perhaps a homocysteine and methylmalonic acid levels test.
Based on the results, your healthcare provider can advise you on the best course of treatment.
If your low B12 level is due to dietary deficiencies, your healthcare provider may recommend that you take B12 supplements, eat foods rich in B12, such as eggs, fish, beef, fortified breakfast cereals, and other fortified dairy products.
In some cases, your healthcare provider may recommend that you receive B12 injections to quickly and effectively raise your B12 levels. If a medical condition is affecting your ability to absorb B12, such as pernicious anemia, you may need to take B12 shots for life.
It is important to follow your healthcare provider’s instructions to ensure that your B12 levels stay in line. Additionally, if you are experiencing any other symptoms, such as fatigue, nerve damage, or balance issues, it is important to talk to your healthcare provider about these as well.
What are the warning signs of vitamin B12 deficiency?
Early warning signs of vitamin B12 deficiency can include fatigue, mouth ulcers, weight loss, diarrhea, rapid heartbeat, jaundice (yellowing of skin and eyes), lack of appetitive, poor memory and concentration, confusion, difficulty walking, irritability, depression, and changes in nerve sensation, especially in the hands and feet.
Some people may also experience tingling and numbness in their hands and feet, as well as anemia, muscle spasms, and abdominal pain. If you experience any of these symptoms, it is important to speak with a doctor right away to determine the cause of the symptom.
What blocks B12 absorption?
Primarily related to your gastro-intestinal tract and surrounding organs. These include: improper digestion and break down of proteins, inadequate stomach acid leading to poor release of B12 from food, a lack of intrinsic factor, certain medications, celiac and Crohn’s disease, and Sjogren’s Syndrome.
Improper digestion and break down of proteins can directly block B12 absorption because B12 is a protein, and if it is not broken down and released, it will not be absorbed.
Inadequate stomach acid can prevent B12 from being released from food, preventing absorption. Intrinsic factor is a glycoprotein produced by cells in the stomach, and it is required for B12 absorption.
Those who have a lack of intrinsic factor can not absorb B12 properly. Certain medications, such as proton-pump inhibitors and metformin, can reduce the secretion of stomach acid, leading to inadequate stomach acid and the inability to properly release B12 from food and leading to poor absorption.
Another factor is celiac and Crohn’s disease. Celiac Disease isn’t directly related to B12 absorption, but Crohn’s can cause damage to the small intestine which can prevent B12 from being absorbed properly.
Finally, Sjogren’s Syndrome is an autoimmune disorder that affects the mucosal cells such as in the stomach and intestines, resulting in poor production of intrinsic factor, leading to poor B12 absorption.
Can stress cause B12 deficiency?
Yes, it is possible for stress to cause B12 deficiency. It is believed that high levels of stress can lead to disruptions in the gastrointestinal tract, which is where B12 absorption occurs. Additionally, stress can cause a breakdown of the protective mucous layer in the intestines, which can also contribute to B12 deficiency.
Additionally, people under chronic stress may not have an optimal diet, leading to reduced absorption of B12. Therefore, it is possible for stress to cause B12 deficiency, especially if an individual doesn’t take proactive steps to reduce stress and/or eat a nutritious diet.
What autoimmune disorders cause low B12?
Autoimmune disorders are conditions in which the body’s immune system mistakenly attacks healthy tissue. This can lead to a range of symptoms, including low levels of B12. Pernicious Anemia and Graves’ Disease are two autoimmune disorders that often cause low B12.
Pernicious anemia is an autoimmune disorder of the stomach that stops the body from properly absorbing B12 from food. The condition usually develops when the body’s immune system mistakenly damages the stomach’s lining and the cells that produce intrinsic factor, a protein needed to absorb B12 in the intestine.
Symptoms of pernicious anemia include fatigue, a weakened immune system and poor digestion.
Graves’ disease is an autoimmune disorder of the thyroid gland, which often causes low B12 levels. This condition causes the body to produce too much thyroid hormone, which leads to a range of symptoms, such as rapid heartbeat, weight loss and fatigue.
As the thyroid hormones interfere with the metabolism of B12, low B12 levels often occur in people with Graves’ disease. Other autoimmune disorders that can cause low B12 levels are systemic lupus erythematosus (SLE), rheumatoid arthritis, type I diabetes, celiac disease and Hashimoto’s disease.
When should I take B12 morning or night?
It largely depends on an individual’s own preference and lifestyle. Generally, taking B12 in the morning allows for greater absorption of the nutrient throughout the day, allowing the levels of B12 in your system to peak at the most beneficial time.
Similarly, B12 taken in the morning may have a more profound impact on energy and cognitive performance during the day. On the other hand, taking it at night may have far less of an effect on daytime energy and thus may be a wiser choice for those who are sensitive to B12’s energizing effects.
Ultimately, everyone is different and should experiment to determine which time of day works best for them.
What medications should not be taken with B12?
Due to interactions between Vitamin B12 and certain medications, it is important to consult a healthcare professional before taking any supplements or medications if you are already taking B12. Specific medications that should not be taken with Vitamin B12 include:
• Warfarin: This anticoagulant medication could interact with B12, increasing the risk of adverse effects.
• Metformin: Taking B12 and metformin together may decrease the absorption of both medications and potentially lead to negative side effects.
• Antibiotics: B12 may reduce the efficacy of certain antibiotics, such as ceftriaxone and doxycycline.
• Trimethoprim-sulfamethoxazole: This drug combination may lower the effectiveness of B12.
• Chemotherapy drugs: B12 may interfere with certain chemotherapy drugs, such as methotrexate and procarbazine.
• Nonsteroidal Anti-Inflammatory Drugs (NSAIDS): Combining B12 with NSAIDS may reduce its absorption and efficacy.
• Levothyroxine: This medication may reduce the absorption of B12.
It is always best to check with your healthcare provider before taking any supplements or medications while taking Vitamin B12.
Can vitamin B12 be taken on empty stomach?
Yes, vitamin B12 can be taken on an empty stomach, however, it is important to consider the form of the vitamin B12 supplement you are taking. Generally, vitamin B12 supplements come in three forms: oral tablets, oral sublingual (under the tongue) tablets and shots.
Depending on the form of supplement, taking it on an empty stomach can vary.
For example, when taking an oral tablet, it is ok to take it on an empty stomach, as the body has much greater bioavailability when taken in this way. On the other hand, sublingual tablets should not be taken on an empty stomach as they need to be broken down and released in the stomach, which requires something to be present in order for it to work.
Finally, when taking a vitamin B12 shot, many experts suggest taking it on an empty stomach, as it helps to maximize absorption and prevent digestive discomfort.
In the end, it is important to consult a doctor or healthcare professional to ensure you are taking the proper form and method of supplementation for your individual needs.
