The B-complex vitamins contains eight forms: B1, B2, B3, B5, B6, B7, B9, and B12 – all play key roles in maintaining and lubricating our body like oil does for a car’s engine. If there is any deficiency of B vitamins in the body, it can result in physical or psychological issues.

Let’s discover the benefits of some of the B-complex vitamins

B9 (folate) –plays a vital role in preventing depression, memory loss and the issues related to development of the fetal central nervous system. Without the B9 vitamin, it would be difficult for the fetal spinal cord and brain to develop normally. The B9 vitamin plays a key role in pregnancy because it assists fetal development and prevents any neurological birth defects.

The nervous system –For our nervous system to function properly, we need vitamin B. Diseases such as Parkinson’s can be prevented with vitamin B6 (also known as pyridoxine) and it also helps reduce other neurological problems like depression, seizures, and headaches among others. While vitamin B12 (also known as methylcobalamin) is responsible for the resolution of Bell’s palsy, it can also be used to minimize other neurological problems.

A lack of vitamin B12 can affect the neurological system, thereby resulting in spasticity–or tightness–of the arms and legs, resulting in the inability to walk normally, as well as discomfort with the bladder and bowels.

Blood glucose –In order to maintain a constant level of energy throughout the day to keep it going, the body requires certain levels of glucose. That’s where the role of Vitamin B6 comes in. As the consumption and level of calories reduces, the body will look for additional glucose to keep it moving. Vitamin B6 converts the nutrients and carbohydrates in the system into glucose so that the body can continue to function.

Hair improvement – The B vitamins not only protect our body from breaking down but they are also responsible for hair improvement. They provide nutrients to the whole body, including our hair and hair follicles. When the body lacks the vitamins B1, B2, B3, and B5, hair follicles are being poorly nourished and hair can fall out.

Also, when the body is not getting sufficient folic acid (vitamin B9) it can hinder the process of cell division inside the hair follicle cells, thereby making the growth of hair much slower.

Other benefits

Recent research carried out by the American Cancer Society prove that consumption of vitamin B9 at the recommended dose will help reduce the level of risk for cancer. B1 helps the body to effectively circulate blood. Vitamin B5 and B12 are responsible for helping the body to prevent anemia, while vitamin B6 helps the body to metabolize proteins and enzymes.

Vitamin B2 and B12 are responsible for the development of new red blood cells, while vitamin B5 ensures that the gastrointestinal and immune systems are performing their roles in the body properly.

Without the B-complex vitamins, the body cannot function properly and can easily break down. Supplementation can provide people with deficiencies the adequate B vitamins needed to stave off illness and disease.
