What is vitamin B complex?
Vitamin B complex is a complex of eight water-soluble vitamins our body requires. Each vitamin has a significant role to play in the body. 
B complex vitamins list -
<ol>
<li>Vitamin B1 (Thiamine)</li>
<li>Vitamin B2 (Riboflavin)</li>
<li>Vitamin B3 (Niacin)</li>
<li>Vitamin B5 (Pantothenic Acid)</li>
<li>Vitamin B6 (Pyridoxine)</li>
<li>Vitamin B7 (Biotin)</li>
<li>Vitamin B9 (Folic Acid)</li>
<li>Vitamin B12 (Cobalamin)</li>
</ol>
B vitamins are critical for energy metabolism, cellular function, DNA synthesis, brain signalling, and many more. They also act as co-enzymes that are vital for major physiological processes taking place in the body. 
Whole grains, legumes, pulses, eggs, poultry, meat, green leafy vegetables, nuts, and seeds are a few vitamin B foods. 
Vitamin B complex: Benefits & Uses
Vitamin B benefits our body in many ways. Let's discuss them.
<ol>
<li>Energy production: B vitamins are critically needed to metabolize carbohydrates, protein, and fats. It is because of the same reason why taking a multivitamin or vitamin B complex tablet can keep you energized. Dietary insufficiency of vitamin B complex can make you feel lethargic or sluggish. </li>
<li>Support brain function: Vitamin B act as a precursor to a range of neurotransmitters and other compounds necessary for brain function. For example, vitamin B1 act as a co-enzyme during the synthesis of nucleic acids, and vitamin B5 assists in the structure of brain cells. Studies support that a deficiency of vitamin B complex may result in cognitive decline, depression, and dementia.</li>
<li>Promote healthy skin, nails and hair: B vitamins like vitamins B3, B6, B5, and B12 are vital for a healthy skin texture and hydration and reduce inflammation. Vitamin B6 and B12 help regulate hormones that can affect hair growth and encourage healthy red blood cell production to deliver oxygen and nutrients to the hair follicles. Similarly, vitamin B7 or biotin support strong nails and hair by promoting keratin production.</li>
<li>Healthy heart: Vitamin B6 and B12 are critical to lower homocysteine levels in the blood, which otherwise can increase the heart disease risk. Vitamin B2 and B2 also keep cholesterol levels in control and blood vessels healthy. </li>
<li>Strengthen muscles: Vitamin b complex is necessary for developing muscle strength as they support muscle growth and repair. B Vitamins are responsible for a continuous supply of oxygen and nutrients to the muscles and amino acid metabolism.</li>
<li>Better digestive health: Vitamin B complex is involved in the production of enzymes that assist digestion, prevent inflammation of the gut lining and keep it intact.</li>
<li>Boost eye health: Vitamin B complex helps protect the retina and prevent eyes from the effects of free radicals and oxidative stress.</li>
