Vitamin B refers to eight different vitamins. The body uses all of the B vitamins to turn food into energy. Every vitamin has a different part in a person’s overall health. Eight of the B vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and  B12 (cobalamin). B vitamins are water-soluble and are naturally present in meat, leafy greens, dairy, legumes, peas, beans, and whole or fortified grains. They are crucial for a number of physiological functions, including the production of red blood cells and the conversion of food into energy.

Food sources of vitamin B complex: Salmon, chicken, beef, nuts, seeds, avocado, spinach.


There are several health benefits about this vitamin, some of its benefits include:

  • Promotes metabolism: B vitamins serve an important part in metabolism, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), and B12 (cobalamin). They work to transform foods such as proteins, lipids, and carbs into energy the body can utilise. B vitamin deficiency has been linked to altered metabolism and energy imbalances, according to studies. For instance, a study in the journal “Diabetes Care” discovered that increased B vitamin intake was linked to improved glucose absorption and a lower risk for getting diabetes.
  • Supports Brain health: B vitamins’ impact on brain health has been well investigated. Cognitive performance and avoidance of dementia caused by age have been linked to vitamins B6, B9 (folate), and B12 intake. The importance of these B vitamins in homocysteine breakdown for brain function was underlined by research in the journal “Nutrients”. A lower risk of dementia and cognitive impairment is linked to lower homocysteine concentrations. Additionally, a study that was published in “JAMA Psychiatry” discovered a link between higher folate intake and a decreased risk of depression.
  • Enhances RBC production: Red blood cell (RBC) formation depends on several B vitamins, including B2 (riboflavin), B9 (folate), B5 (pantothenic acid), B6 (pyridoxine), and B12 (cobalamin). Vitamin B12 is particularly crucial since a lack of it can cause megaloblastic anaemia, a kind of anaemia. According to a study in the “Blood” journal, people with megaloblastic anaemia can produce more red blood cells when they take vitamin B12 and folate supplements.
  • May prevent migrane: B vitamins may be helpful in preventing migraines, according to several research. For instance, a research in “Neurology” looked at the impact of high-dose riboflavin (vitamin B2) consumption on preventing migraines. Riboflavin users significantly decreased their migraine symptoms and frequency, according to the study’s findings. A different study that was published in “Headache” looked into the impact of vitamin B6 and B12 intake on migraines with aura. According to the findings, these B vitamins and folic acid may be able to lessen the frequency and intensity of migraines with aura.

It is crucial to remember that even though these studies have shown encouraging findings, further study is still required to determine the efficacy and ideal amount of B vitamin supplementation for various medical disorders. To choose the best tactic and dose based on specific requirements and aspects, it is advised to consult a healthcare practitioner.


When taken orally, the B complex vitamins help numerous vital internal processes in an integrated way. These vitamins, including thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin (vitamin B7), and cobalamin (vitamin B12), are essential for energy metabolism.

They function as coenzymes, which means that they cooperate with enzymes to speed up enzymatic processes that involve the disintegration of proteins, lipids, and carbohydrates. B complex vitamins help create adenosine triphosphate (ATP), which is the basic energy unit of cells, by assisting in the transformation of these macronutrients into energy that can be used by the body. This procedure is essential for providing the tissues’ and organs’ energy requirements and enabling optimal performance.

B complex vitamins are also necessary for the neurological system to function properly. They participate in the production and metabolism of neurotransmitters, chemical messengers that let nerve cells to communicate. B vitamins, such as B1, B6, B9 (folate), and B12, are important for the synthesis of neurotransmitters like serotonin, dopamine, and gamma-aminobutyric acid (GABA).

These neurotransmitters play an important role in controlling mood, thinking, and general brain activity. B complex vitamins also aid in the development and preservation of the myelin sheath, a covering that protects nerve fibres. This sheath makes it possible for nerve impulses to be transmitted effectively, facilitating seamless communication throughout the neurological system.

B complex vitamins collectively enhance metabolic rate in cells, nervous system health, and breakdown of energy. Their interaction is crucial for a number of physical functions as well as sustaining general health and wellbeing. It’s vital to remember that, despite the fact that each B vitamin serves a different purpose, these responsibilities frequently overlap and depend on one another for effectiveness.


The ideal dosage of the B vitamin complex to take depends on a number of different factors and personal circumstances. Even though a healthy diet usually has enough B vitamins, certain people may benefit from supplements due to an elevated risk of deficiency. This includes people over the age of 50, those who have gastrointestinal problems, those who use antacids, and people who have had weight-loss or stomach surgery. Regular alcohol use, eating a vegetarian or vegan diet, and being pregnant or nursing may all make B vitamin supplements more necessary.

The Food and Drug Administration (FDA) does not regulate supplements, so you should only purchase from a reliable, established brand. This makes it easier to know you’re consuming a high-quality product free of suspicious ingredients.

 If a deficiency has been identified by your doctor, they might be able to suggest a specific type of supplements.
