Vitamin B complex consists of eight water-soluble nutrients essential for energy metabolism, immune function, and nerve health. These vitamins help convert food into energy, produce red blood cells, and maintain healthy skin. Key types include B1 (thiamin), B2 (riboflavin), B3 (niacin), B6, B7 (biotin), B9 (folate), and B12.
The B vitamins in the vitamin B complex include thiamine, riboflavin, niacin (nicotinic acid), niacinamide (nicotinamide), the vitamin B6 group (including pyridoxine, pyridoxal, pyridoxamine), biotin, pantothenic acid, folic acid, and vitamin B12.
Vitamin B12 is present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products [5,12]. Plant foods do not naturally contain vitamin B12. However, fortified breakfast cereals and fortified nutritional yeasts are readily available sources of vitamin B12 that have high bioavailability [13,14].
Most folate-deficiency anemia is caused by a lack of folic acid in the diet. Leafy vegetables, citrus fruits, beans, and whole grains are natural sources of folic acid. Folate-deficiency anemia in pregnancy may cause a neural tube defect. This is when the brain or spinal cord doesn't develop normally.
Cancers affecting the gastrointestinal (GI) tract, like stomach, pancreatic, and intestinal cancers, can cause B12 deficiency by damaging cells or blocking absorption; also, blood cancers (leukemia/lymphoma) and sometimes breast/cervical cancers are linked, often because tumors consume nutrients or treatments disrupt absorption, making low B12 a potential symptom of underlying malignancy.
What are the neurological symptoms of folate deficiency?
The neurologic manifestations of folate deficiency overlap with those of vitamin B12 deficiency and include cognitive impairment, dementia, depression, and, less commonly, peripheral neuropathy and subacute combined degeneration of the spinal cord.
In conclusion, our results show that lower vitamin B12 was associated with insomnia symptoms and sleepiness in specific groups of participants. However, further research with objective measurements of sleep is crucial to assess the relationship between sleep and vitamin B12.
If you have vitamin B12–deficiency anemia, you may have the typical symptoms of anemia at first, such as fatigue, paleness, shortness of breath, headaches, or dizziness. If left untreated, you may start to notice brain and nervous system symptoms.
Choose B-complex for general support (energy, stress, overall function) or B12 alone if you have a diagnosed deficiency or follow a vegan/vegetarian diet, as it's crucial for nerves and red blood cells, but B-complex already contains B12 and other essential B vitamins. A healthcare provider should guide you, especially if symptoms are severe or absorption issues exist, as B12 is often the most common deficiency, but other B vitamins are vital too.
Who should not take B complex? People with certain medical conditions, like kidney issues or allergies to B vitamins, should avoid or use B complex supplements cautiously.
If you're suddenly craving meat for no clear reason, it could be your body's way of signaling a vitamin B12 deficiency. According to Pallian, people low in B12 may also find themselves unusually hungry for fish or eggs.
The effect of low vitamin B12 status, which results in altered cellular metabolism, on age-related disease and functional decline including cognition, cardiovascular disease and bone health, is an active area of investigation [2,4].
However, if you are looking for Vitamin B12-rich fruits, some studies suggest that certain vitamin B12 fruits, such as bananas, apples, and berries (blueberries and strawberries), can increase vitamin B12 levels. No significant B12 content is present in these fruits to meet your needs.
Fruits and vegetables don't contain vitamin B12, but select plant foods are a good source, including fortified nutritional yeast, fortified breakfast cereals, and nori (dried seaweed).
Figs. Figs are a delicious and sweet flavoured dry fruit. Figs are good source of Vitamin B12. you can eat them dried, fresh, or by incorporating them into recipes like jams, salads, or desserts.
It's fixable. The best thing about B12 deficiency? It's one of the most treatable causes of memory loss, fatigue and brain fog – once you know what you're dealing with. If you're feeling more tired than usual, struggling to concentrate, or just not feeling like yourself, it's worth speaking to your GP.
What deficiency causes tingling in hands and feet?
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
