B12 works by converting the food we eat into sugar and other types of fuel that keep the body running smoothly. B12 is often associated with weight loss because of its ability to boost metabolism and provide lasting energy.
Energy is important when it comes to losing weight as well. Vitamin B12 injections help with this process by increasing your energy, which ramps up your metabolism. A faster metabolism burns more calories. This vitamin is also used to help your body get rid of fat more efficiently.
A Vitamin B12 deficiency can lead to long-term weight control problems. When the body's natural balance is disrupted, it typically responds by slowing down your metabolism, conserving fat stores, and burning fewer calories throughout the day.
Because vitamins B9 and B12 are crucial for cell metabolism, their deficiency can lead to alarming health consequences. Low levels of folate and cobalamin can cause DNA synthesis interference, cellular inflammation, and elevated synthesis of fat and homocysteine [6].
Vitamin B12 Affects Metabolism
Many studies found that it is vitamin B12 deficiency that leads to higher chances of weight gain and obesity. An increased amount of vitamin B12, whether or not through vitamin injections, does not seem to lead to weight gain.
Once you begin treating your vitamin B12 deficiency, it can take up to six to 12 months to fully recover. It is also common to not experience any improvement during the first few months of treatment. If you can, it's a good idea to address what's causing the deficiency.
High doses of vitamin B-12, such as those used to treat a deficiency, might cause: Headache. Nausea and vomiting. Diarrhea.
Vitamin B12 is considered an important brain and nervous system micronutrient and is often used for anxiety. It helps to ensure normal function for your nerves, which can help combat physical symptoms of anxiety.
Thus if you're otherwise healthy but still continue to feel tired after taking a B-12 supplement, it could be a sign of a mild allergic reaction. If a rash, difficulty breathing or swelling coincides with taking your dose of B-12, get to the doctor right away.
There's no solid proof that vitamin B-12 shots, also called injections, help you lose weight. Vitamin B-12 is a water-soluble B complex vitamin. It's found naturally in many foods, such as meat, fish and dairy products.
Studies show that a B12 deficiency can sometimes result in a loss of appetite. If you take a B12 supplement to treat this deficiency, you may experience an increase in appetite, but that's really a restoration of a normal level. In general, for healthy people, taking B12 neither increases nor decreases appetite.
Vitamin B12 helps increase the body's production of melatonin, making it important for regulating sleep-wake cycles. Higher B12 levels have been associated with a lower risk of depression.
Because of its role in energy metabolism, vitamin B12 is often promoted as an energy enhancer and an athletic performance and endurance booster. However, vitamin B12 supplementation appears to have no beneficial effect on performance in the absence of a nutritional deficit [97,98].
One of those vital nutrients is B12, also known as cobalamin. B12 promotes healthy hair growth by assisting in the production of oxygen-rich red blood cells, which feed hair follicles.
Deficiency of Vitamin B12 can result in hematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss [9]. It is also known to worsen depression by excitotoxic reactions caused by the accumulation of homocysteine [10].
B12 acts as a cofactor in synthesis of neurotransmitters such as serotonin and dopamine, thus B12 deficiency affects mood, emotions and sleeping and can lead to psychiatric disorders.
Using high doses of vitamin B12 (cyanocobalamin) to treat anemia can lead to low levels of potassium and/or high platelet counts in the blood. Severely low potassium levels can cause life-threatening heart problems, and high platelet counts can lead to issues with too much blood clotting.
If you have any of the following health problems, consult your doctor or pharmacist before using this medication: a certain eye disease (Leber's optic neuropathy), a certain blood disorder (polycythemia vera), gout, iron or folic acid deficiency anemia, low potassium blood levels (hypokalemia).
Long-term vitamin B12 deficiency can cause nerve damage. This may be permanent if you do not start treatment within 6 months of when your symptoms begin. Vitamin B12 deficiency anemia most often responds well to treatment. It will likely get better when the underlying cause of the deficiency is treated.
“How soon will I feel less tired after a B12 Injection?”- is the question we get asked a lot. Since B12 shots are injected intramuscularly bypassing the digestive process, they start to work immediately. Typically, our patients experience positive effects between 24-72 hours after the treatment.
B12 supplements are usually safe. For adults, doctors recommend 2.4 micrograms a day. If you take more than what you need, your body passes the rest out through your pee. Still, high doses could have some side effects, like dizziness, headache, anxiety, nausea, and vomiting.
Diet. Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
