In most cases, taking a B vitamin will not lead to weight gain. However, people who are deficient in vitamin B12 might notice the scale creep upwards once they start supplementing. That's because loss of appetite is a symptom of vitamin B12 deficiency.
Despite the numerous processes in which vitamin B12 is involved, there's little evidence to suggest that it has any influence on weight gain or loss.
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. Vitamin B-12 is added to some foods and is available as a dietary supplement.
In some people, high levels of B12 may cause gastrointestinal problems such as bloating and diarrhea. And if you have high blood pressure or poor cardiovascular health, having too much B12 may further complicate these issues. Pregnant and breastfeeding women may also need to be especially mindful of B12 levels.
Gastrointestinal issues. A B12 deficiency may also cause diarrhea, nausea, constipation, bloating, gas, and other gastrointestinal symptoms ( 2 , 19 ). These issues can affect both adults and children ( 2 , 20 ).
Gastritis: Gastritis is inflammation of the stomach lining, and it's a common cause of vitamin B12 deficiency. It can cause vitamin B12 deficiency due to a lack of hydrochloric acid in your stomach, which is needed for vitamin B12 absorption.
Vitamins B, D, iron, and magnesium are four well-known weight reduction vitamins. Vitamin B helps the body to convert food into energy. It also plays a role in metabolism and cell function. A lack of vitamin B can lead to fatigue and weight gain.
B-complex vitamins: These help metabolize carbohydrates, fats, and proteins, activating stored energy instead of letting it turn to fat. Niacin, vitamin B-6, and iron: This impressive trio increases your body's production of the amino acid L-carnitine to help burn fat.
Vitamin D deficiency is linked to many disease processes. It also plays a role in weight gain. If you're struggling with weight loss, there's a very good chance you're also struggling to store adequate amounts of vitamin D in your body.
Vitamin B-12 can cause very rare but serious allergic reactions (anaphylaxis). This includes swelling of the face, tongue, and throat, and difficulty swallowing and breathing. If this occurs after you take vitamin B-12, call 911 or your local emergency services immediately.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
Vitamin B12 deficiency can have distressing neuropsychiatric symptoms. It can have an etiological role in clinical presentations like depression, anxiety, psychosis, dementia, and delirium, requiring screening of at-risk populations.
Vitamin B12 for Weight Loss
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.
Several types of supplements — protein powders, mass gainers, creatine, and pre-workouts — can help you gain weight if you use them in combination with a balanced diet. In general, protein powders and mass gainers are your best bets if you're simply looking to boost your calorie intake.
The body relies on a variety of vitamins to maintain optimal health, and B12 is among the most important for weight management. If you want to lose excess weight, vitamin B12 is not only energy-enhancing, it has also been linked to weight loss.
1. Magnesium: Magnesium levels in the body regulates blood glucose levels and a good control over glucose matters a lot when it comes to weight loss.
Magnesium helps regulate metabolism and supports healthy muscle function, both of which are essential for weight loss.
Poor sleep, sedentary activities, and eating too many processed or sugary foods are just some of the habits that may increase your risk of weight gain. Yet, a few simple steps — such as mindful eating, exercise, and focusing on whole foods — can help you reach your weight loss goals and improve your overall health.
As summarized in the table provided, vitamin B12 (cobalamin) absorption and utilization by the body can be compromised with the chronic use of certain medications which include: colchicine, chloramphenicol, ethanol, histamine 2 receptor antagonists (H2RA), metformin, and proton pump inhibitors (PPI).
B12 deficiency is also characterised by neurological problems, such as hallucinations, paranoia and insomnia. B12 needs to interact with acid in the stomach to be bio-available in the rest of the body. So problems with indigestion and heartburn can be linked to B12 deficiency.
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.
