​Doc recommended best sources of Vitamin B12 for vegetarians​

The deficiency of this vitamin puts the human body through a range of diseases including drastic weight loss extreme fatigue and loss of concentration. We are talking about vitamin B12 or cobalamin, the vitamin that plays a key role in DNA synthesis and several other major functions of the body. A deficiency in vitamin B12 can have widespread effects on health, impacting both physical and mental well-being. A human being needs to consume 2.4 micrograms (mcg) of vitamin B12 a day.

The neurological manifestations of vitamin B12 deficiency can range from mild to severe and may include tingling or numbness in the hands and feet (paresthesia), difficulty walking, balance problems, memory loss, cognitive impairment, and depression. These symptoms arise due to the role of vitamin B12 in maintaining the integrity of the myelin sheath, a protective covering of nerve fibers. Deficiency-induced damage to the nervous system can result in irreversible neurological deficits if left untreated.

In addition to neurological effects, vitamin B12 deficiency has been associated with psychiatric disorders such as depression, anxiety, and psychosis. The exact mechanisms underlying these psychiatric symptoms are not fully understood but may involve alterations in neurotransmitter function and brain chemistry. Treating the underlying B12 deficiency may improve psychiatric symptoms and overall mental health.

Low levels of vitamin B12 are dangerous to heart health

Emerging research suggests that vitamin B12 deficiency may contribute to cardiovascular disease risk factors, including elevated levels of homocysteine, a compound linked to atherosclerosis and cardiovascular events. High homocysteine levels resulting from B12 deficiency can impair endothelial function, promote inflammation, and increase the risk of heart disease and stroke.

Since vitamin B12 is abundantly found in non-vegetarian foods, those who do not consume such foods are at a higher risk of developing a deficiency of this vitamin. According to Dt. Rashi Tantia, HOD - Dietician, Metro Hospital, Faridabad, the best sources of Vitamin B12 for vegetarians include:

- Cheese and dairy products

- Fortified cereals

- Fortified juices

- Fortified milk and tofu

- Vitamin water

- Whey powder


"In addition to eating the foods listed above, vegetarians who are deficient in Vitamin B12 may also want to think about taking supplements or increasing their intake of fortified foods high in the vitamin. Increase the amount of nutritional yeast, fortified plant-based milk, and fortified meat alternatives in their diet. Regularly check their blood levels for B12 deficiency and speak with a healthcare professional for advice on how to manage it," Rashi adds.

Vitamin B12 deficiency can manifest in various signs and symptoms, including fatigue, weakness, and lightheadedness due to decreased red blood cell production and impaired oxygen delivery to tissues. Neurological symptoms such as numbness or tingling in the hands and feet, difficulty walking, memory problems, and cognitive decline may also occur, reflecting nerve damage and impaired brain function. Additionally, individuals may experience mood changes, including depression, irritability, or anxiety. Digestive issues such as loss of appetite, weight loss, and constipation may arise, along with glossitis (inflammation of the tongue) and mouth ulcers. Prompt recognition and treatment of vitamin B12 deficiency are essential to prevent complications and improve overall health.

Vegetarians and Vegans: Since vitamin B12 is primarily found in animal products, individuals who exclude these foods from their diet may not get enough of this essential nutrient.

Elderly Individuals: Aging can impair the body's ability to absorb vitamin B12 from food, leading to deficiency, particularly in those over 50 years old.

Individuals with Gastrointestinal Disorders: Conditions such as celiac disease, Crohn's disease, and atrophic gastritis can affect the absorption of vitamin B12 in the digestive tract, increasing the risk of deficiency.

People Who've Undergone Weight Loss Surgery: Certain weight loss surgeries, such as gastric bypass surgery, can reduce the body's ability to absorb nutrients, including vitamin B12.

Those on Long-Term Antacid Use: Proton pump inhibitors (PPIs) and H2 receptor antagonists, commonly used to treat acid reflux and ulcers, can decrease stomach acid production, which is necessary for the absorption of vitamin B12.

Individuals with Pernicious Anemia: This autoimmune condition affects the stomach's ability to produce intrinsic factor, a protein necessary for vitamin B12 absorption.

Heavy Drinkers: Excessive alcohol consumption can damage the lining of the stomach and impair vitamin B12 absorption.
