Introduction
The vitamins B-complex are well-known examples of water-soluble nutrients that are easily absorbed by a healthy stomach and excreted by the kidney. They are necessary for key physiological activities and play an important role in maintaining healthy health. (1). Vitamin B complex was originally assumed to be a single nutrient found in extracts of rice, liver, and yeast. However, researchers eventually discovered that these extracts included numerous vitamins, which have been assigned unique numbers. Vitamins B’s are a group of water-soluble vitamins that perform vital functions in cell metabolism. Though they have similar names, research demonstrates that these vitamins are chemically separate and frequently coexist in the same foods.
Importance of Vitamin B Complex for Health and Wellness
Vitamin B complex plays a crucial role in maintaining overall health and wellness. Comprising a group of eight water-soluble vitamins, it supports various bodily functions, including metabolism, energy production, nerve function, and cell health. From aiding in the conversion of food into energy to supporting the nervous system, each B vitamin contributes uniquely to our well-being.

| B3 (Niacin) | Supports energy production, aids in DNA repair, helps maintain healthy skin, and supports nervous system function. |
| B5 (Pantothenic Acid) | Necessary for synthesizing and metabolizing fats, proteins, and carbohydrates, and producing hormones. |
| B6 (Pyridoxine) | Plays a role in amino acid metabolism, neurotransmitter synthesis, and red blood cell formation. |
| B7 (Biotin) | Vital for metabolism of carbohydrates, fats, and amino acids, and supporting healthy hair, skin, and nails. |
| B9 (Folate) | Crucial for DNA synthesis, red blood cell formation, and fetal development during pregnancy. |
| B12 (Cobalamin) | Essential for nerve function, DNA synthesis, red blood cell production, and energy metabolism. |

Deficiency of vitamin B complex
- Vitamin B1, B2, and B3 deficiencies can lead to undernourished hair follicle cells.
- Vitamin B7 (biotin) is also required to maintain the texture, tone, and strength of our hair, and a lack of it might result in hair loss. If you have persistent skin problems or are tired of having a dull and unhealthy complexion, it might be due to a vitamin B deficiency.
- Inadequate intake of vitamins B9 or folic acid can decrease cell division inside hair follicles, slowing hair growth. A number of B vitamins are important for nail health.
- Vitamin B12 (riboflavin) helps the body to absorb the essential mineral iron, which is necessary for healthy and strong nails. Without enough access to usable iron, the fingernails can turn white, brittle, thin and grow abnormally. Vitamin B12 in addition to nail health also plays an important role in the formation of red blood cells. A deficiency of B12 can lead to the development of anemia. One of the symptoms of anemia is pale, unhealthy or unsightly nails.
According to research, heavy drinkers have an increased requirement for B vitamins, and effective treatment of B-complex vitamin deficiencies may lessen alcohol cravings. According to double-blind studies, taking a vitamin B-complex multivitamin may help lower anxiety, perceived stress, and fatigue.
