Let’s have a detailed look at the B complex vitamins:
B Complex Vitamins | Functions | Sources | Deficiency and Health Impacts |
B1 (Thiamine) | Thiamine is involved in nerve function, muscle contraction, and pyruvate metabolism. It is also necessary for converting carbohydrates into energy. | Thiamine is found in whole grains, meat (especially pork), fish, legumes, seeds, and nuts.
RDA:
| A severe brain disorder called Wernicke-Korsakoff syndrome and a cardiovascular and neurological disease called beriberi can result from thiamine deficiency.
|
B2 (Riboflavin) | Riboflavin is critical in breaking down proteins, fats, and carbohydrates, ensuring the body has enough energy.
It additionally aids in maintaining healthy skin and proper eye functions. | Riboflavin is found in eggs, milk, green vegetables, meat, and enriched flour.
RDA:
| Ariboflavin deficiency can result in ariboflavinosis, which is characterised by sore throat, redness and swelling of the throat and mouth lining, cheilosis (lip cracks or sores on the outside of the lips), angular stomatitis (mouth corners), and magenta tongue (red, swollen tongue). |
B3 (Niacin) | Niacin supports the digestive system, skin, and nerves.
It is also vital for converting food into energy. | Niacin is found in poultry, fish, beef, peanuts, and legumes. Fortified foods like cereals are also a good source.
RDA:
| Niacin deficiency can lead to pellagra, which is characterised by diarrhoea, dermatitis, and dementia. |
B5 (Pantothenic Acid) | Coenzyme A, which is critical for the metabolism of fatty acids and the creation of hormones and cholesterol, requires pantothenic acid to be synthesised. | Pantothenic acid is widely available in plant—and animal-based foods, including meats, grains, legumes, eggs, and vegetables.
RDA:
| Although uncommon, deficiency can result in symptoms like irritation, sadness, exhaustion, and gastrointestinal problems. |
B6 (Pyridoxine) | Pyridoxine is involved in amino acid metabolism, synthesising red blood cells and producing neurotransmitters. | B6 is found in poultry, fish, potatoes, chickpeas, bananas, and fortified cereals.
RDA:
| A deficiency can lead to anaemia, dermatitis, depression, confusion, and a weakened immune system. |
B7 (Biotin) | Biotin is important for the metabolism of fats, carbohydrates, and proteins. It additionally aids in maintaining the health of hair, skin, and nails. | Biotin is found in eggs, nuts, seeds, fish, meat, and certain vegetables, such as sweet potatoes.
RDA:
| A lack of certain nutrients seldom occurs but may lead to hair loss, skin irritations, and weak nails. |
B9 (Folate or Folic Acid) | Folate is essential for red blood cell development, healthy brain function, and DNA synthesis and repair.
It is especially important during rapid growth, such as pregnancy and fetal development. | Leafy green vegetables, legumes, nuts, and fortified cereals are good sources of folate.
RDA:
| A deficiency can lead to megaloblastic anaemia and, during pregnancy, an increased risk of neural tube defects in the fetus. |
B12 (Cobalamin) | Vitamin B12 plays an important role in maintaining the health of nerve tissue, supporting brain function, and producing red blood cells. | Meat, fish, poultry, eggs, and dairy products are examples of animal products that contain vitamin B12, and plant-based or vegetarian diets might benefit from fortified meals and supplements.
RDA:
| A deficiency can cause megaloblastic anaemia, fatigue, weakness, constipation, loss of appetite, and weight loss.
Severe deficiency can also result in neurological abnormalities, including tingling and numbness in the hands and feet. |

After reading about B complex vitamins in detail, it’s time to learn about the benefits and side effects of vitamin B complex. First, let’s understand 7 prominent B complex vitamins benefits:
The B complex vitamins, particularly thiamine (B1), riboflavin (B2), niacin (B3), and pantothenic acid (B5), are important for the process of turning food into energy. These vitamins help enzymes break down carbohydrates, fats, and proteins into glucose, which the body uses as fuel.
Weakness and poor energy levels result from our cells' inability to produce energy effectively without enough B vitamins. For instance, riboflavin is part of the electron transport chain in mitochondria, essential for ATP production, the energy currency of cells. This process ensures we have the energy needed for daily activities and overall bodily functions.
B complex vitamins, including B6 (pyridoxine), B9 (folate), and B12 (cobalamin), are vital for brain health. They support the production and regulation of neurotransmitters like serotonin, dopamine, and GABA, which influence mood, sleep, and cognitive function. For example, Folate and B12 play a vital role in creating SAMe, which is essential for brain function and mood control.
Depression, memory loss, and cognitive decline are just a few of the neurological and psychological problems that can result from vitamin deficiencies. Ensuring adequate intake of B vitamins helps maintain a healthy nervous system and supports mental clarity and emotional well-being.

Vitamins B6, B9 (folate), and B12 create red blood cells. Folate and B12 are involved in DNA synthesis and cell division, which is critical for producing healthy red blood cells. A vitamin deficiency for these vitamins can lead to megaloblastic anaemia, characterised by the production of large, immature, and dysfunctional red blood cells.
This condition can cause symptoms like fatigue, weakness, and shortness of breath. Vitamin B6 aids in the production of haemoglobin, the protein in red blood cells that carries oxygen. Sufficient consumption of these B vitamins guarantees appropriate erythropoiesis and optimal oxygen transportation inside the organism.
B vitamins, particularly B3 (niacin), B5 (pantothenic acid), and B7 (biotin) are beneficial for maintaining healthy skin. Niacin helps improve skin barrier function and hydration, reducing dryness and irritation. Pantothenic acid stimulates the production of new skin cells, which helps in skin regeneration and wound healing. Biotin supports the health of your hair, skin, and nails by assisting in fatty acid synthesis, which is crucial for maintaining skin moisture and integrity.
Deficiencies in these vitamins can lead to various skin issues, such as dermatitis, dry skin, and brittle nails. To combat this, you can take ToneOp Care’s Skin 360 tablets enriched with all the necessary vitamins and minerals.
B complex vitamins, especially B6, B9 (folate), and B12, significantly support the immune system. Vitamin B6 produces white blood cells, which are crucial for fighting infections. Folate and B12 are essential for DNA synthesis and cell division and necessary for the rapid production of immune cells during an immune response.
These vitamins also help maintain the health of the thymus and spleen, organs involved in immune function. A lack of B vitamins might compromise the body's ability to fight infections and illnesses. Apart from dietary sources, you can take Turmeric, Ginger, and Garlic Oil capsules from ToneOp Care, which contain B6, B9, and B12 abundantly to meet your adequate intake and support a robust and effective immune system.
B vitamins, particularly B6, B9 (folate), and B12, contribute to cardiovascular health by regulating homocysteine levels in the blood. Elevated homocysteine is a risk factor for heart disease, as it can damage blood vessels and promote atherosclerosis (plaque build-up in arteries).
Folate, B6, and B12 help convert homocysteine into methionine, an essential amino acid, reducing its levels and lowering the risk of cardiovascular issues. Adequate intake of these vitamins reduces the risk of heart disease, stroke, and hypertension, supporting overall cardiovascular health.
B complex vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), and B6 (pyridoxine), are essential for an efficient metabolism. They act as coenzymes in metabolic pathways that convert carbohydrates, fats, and proteins into energy. This process helps maintain a healthy metabolism, which is crucial for weight management.
An efficient metabolism ensures the body uses all important types of nutrients effectively, preventing fat accumulation and supporting muscle maintenance. Additionally, these vitamins help regulate appetite and support digestive health. Getting enough B vitamins can help you keep a healthy weight and improve your metabolism in general.

The common side effects of B complex vitamins are:
High B complex vitamins, particularly niacin (B3) and folic acid (B9), can cause gastrointestinal discomfort. Niacin, in large amounts, often leads to nausea, stomach cramps, and diarrhoea. This occurs because too much niacin triggers the formation of stomach acids, irritating the stomach lining.
Similarly, too much folic acid can upset the digestive system, leading to bloating and gas. To prevent these unpleasant side effects, it is imperative to follow suggested dosages and speak with a healthcare professional before beginning high-dose supplements.
Taking large doses of specific B vitamins, like niacin (B3), can cause skin reactions known as "niacin flush." This condition involves redness, itching, and a warm sensation on the skin, typically the face and neck.
Niacin causes blood vessels to widen, increasing blood flow to the skin and resulting in these symptoms. While generally harmless, niacin flush can be uncomfortable. Gradually increasing the dosage and taking niacin with food can help minimise this reaction.
Excessive intake of vitamin B6 (pyridoxine) over an extended period can lead to nerve damage. High doses can cause neuropathy, a condition characterised by tingling, numbness, and pain in the hands and feet.
This occurs because vitamin B6 overdosing interferes with nerve cell activity. Although this side effect is rare and typically associated with very high doses, it's important to adhere to recommended daily allowances to avoid potential nerve issues.
Overconsumption of niacin (B3) can lead to liver toxicity. High doses, particularly from supplements rather than food sources, can cause liver damage, leading to elevated liver enzymes, jaundice, and, in severe cases, liver failure. The liver metabolises niacin, and excessive amounts can overwhelm the organ, leading to toxicity.
Symptoms include fatigue, nausea, dark urine, and yellowing of the skin and eyes. Monitoring dosage and consulting a healthcare provider before taking high-dose niacin supplements can help prevent liver damage.
High doses of B complex vitamins can interfere with the effectiveness of certain medications. For instance, high levels of folic acid (B9) can mask vitamin B12 deficiency, leading to neurological complications if left untreated.
Additionally, large doses of niacin (B3) can affect blood pressure and come in contact with blood pressure medications and interact, potentially causing dizziness or fainting. It's important to discuss any supplement use with a healthcare provider to avoid adverse interactions with medications.
