Vitamin B complex is a water-soluble compound that contains several B-group vitamins. Although several vitamins are referred to as a B complex, each one has a unique chemical structure and is differentiated from the others by a number after the B – from B1 to B12.

Injectable form of vitamin B complex contains 5 major B vitamins - B1,B2,B3,B5,and B6. Each of these essential vitamins contributes to your overall bodily function. Some of the wide-reaching supportive roles of B vitamins include the health of the nervous and immune systems, prevention of heart disease and birth defects, support for the liver, skin, and hair, as well as a maintenance muscle tone in the gastrointestinal tract.

Unfortunately, our body doesn’t produce B vitamins, so we must get them through our diet or supplementation. Because B vitamins are water-soluble and not stored in the body, they must be replenished daily.

Yep, B vitamins are essential to your well-being. Read on to learn more about how these nutrients can benefit your health and well -being.


Vitamin B complex is an essential water-soluble vitamin complex that plays pivotal roles in cellular function and energy metabolism, acting as co-enzyme in many catabolic and anabolic enzymatic reactions. Numerous clinical studies have also demonstrated the benefits of B complex on energy metabolism, neurological function, neural inflammation, and oxidative stress.

The benefits of B complex vitamins extend to more than physical health, they also aid mental function and are helpful in treating mild to moderate depression in some people.


Thiamine Hydrochloride -(Vitamin B1) - is an essential nutrient that all tissues of the body need to function properly. It is crucial to supporting healthy memory, alertness, and the nervous system, including your brain. B1 assists the transmission of nerve impulses in the brain and spine and also helps convert food into energy. This vitamin also supports good mood. Studies have shown that those with high Thiamin intake are less likely to suffer from anxiety or depression.

Thiamin plays a crucial role in metabolic processes. It helps make adenosine triphosphate (ATP), a substance needed by every cell in the body to produce energy.

Vitamin B1 is often called an anti-stress vitamin because it works to strengthens our immune system, protecting us from cold and flu.

Riboflavin -(Vitamin B2). If you’re feeling low on energy these days, then it could be your tank is running low on vitamin B2. Riboflavin break down carbohydrates, proteins, and fats to generate energy, while also allowing oxygen to be used by the body. It also works as an antioxidant to help fight free radicals - particles in the body that damage cells and cause premature aging. It may prevent the development of heart disease. Riboflavin is important for red blood cell production, which is necessary for transporting oxygen throughout the body. Riboflavin assists in wound healing and tissue repair. It improves the body's ability to clear up skin lesions on its own by secreting mucus. Riboflavin helps moisten the skin as well, preventing eczema and dermatitis.

Niacinamide - (Vitamin B3) helps keep our cholesterol and blood pressure at a healthy level. It is also prescribed to patients at risk for heart problems. It is one of the best vitamins for skin health, it increases hydration to produce more fatty acids and ceramides, substances that seal in moisture. Hydrated skin equals fewer wrinkles and age spots.

Dexpanthenol - Pantothenic acid (Vitamin B5) and its derivative Pantethine may reduce fats and triglycerides in patients with high cholesterol. Vitamin B5 has long been associated with reducing stress and other mental health conditions such as anxiety and depression. It also improves mental clarity and fitness by regulating hormone production in the brain.

Dexpanthenol helps regulate the heart rate as it moves blood throughout the body and can also help control blood pressure by keeping blood vessels supple and pliant.

This vitamin can improve performance and endurance and it is critical to a well-functioning heart, which keeps you going longer.

Vitamin B5 anti-aging properties can't be beaten for preserving healthy skin and hair. Vitamin B5 delays the appearance of age spots and wrinkles. Pantethine can also help hair retain its youthful pigmentation, repressing the growth of gray hair. B5 contains antioxidants that preserve elasticity in the skin and keep the skin looking tighter and healthy for longer.

Pyridoxine Hydrochloride-(Vitamin B6) helps the body manufacture three important hormones - serotonin and norepinephrine (which regulate mood), and melatonin (which controls the sleep cycle). Most of us know how stress can affect our mood and energy levels during the day. However, handling stress isn’t just about being mentally strong enough. Chronic or long-term stress can actually change the brain’s biology and make us more vulnerable to conditions like depression and anxiety. Vitamin B6 is arguably the most important B vitamin for mental and brain health because it is critical for production of calming neurotransmitters, including serotonin and GABA. These neurotransmitters can help us feel more stable and less overwhelmed in the face of trauma or day-to-day stressors.

Having a healthy amount of B6 can also protect us from many medical conditions, including diabetes, PMS, nausea and morning sickness, and poor immune function. Maintaining healthy levels of vitamin B6 in your blood might also help reduce your chances of cancer.

Vitamin B6 helps the body regulate levels of homocysteine in the blood.

High levels of homocysteine have been associated with dementia, Alzheimer’s disease, and cognitive decline.

Pyridoxine also guards against acne, hair loss, eczema and dry skin that causes premature wrinkles. This powerful vitamin helps to convert food to fuel, boost energy, heal faster and feel better.
