Our Vitamin B Complex delivers eight types of Vitamin B, all of which have an important role in healthy metabolism,[1] [2] blood cell creation and growth. They make sure the energy we consume gets to where it needs to go, especially to the brain, muscles and nervous system. These types of Vitamin B can be found in many foods, but if you do not have a varied diet, supplementation is a great way to ensure you get enough of each type.

A 2002 study on 30 men and 23 women found that Vitamin B12 and Folic Acid supplementation reduced homocysteine concentrations, which is a risk factor in cardiovascular disease. Another 2012 study tested the effects of B12 supplementation on heart rate variability on 47 healthy subjects over 60. After three months, the subjects who were given Vitamin B12 showed an improvement in heart rate variability over their placebo counterparts.[3] Additionally, Vitamin B3 lowers triglycerides and bad (LDL) cholesterol while increasing good (HDL) levels.[4]

The macula is located in the middle of the retina. Age-related Macular Degeneration is a disease in which the macula progressively deteriorates due to aging, leading to blurry vision, loss of colour and the appearance of
dark or empty spots in the central line of vision.[5] A 2010 study examined the effects of Vitamin B6, Vitamin B12 and folic acid supplementation on 5442 women aged 40 and above for 7 years. It concluded that long term supplementation reduced the risk of developing Age-related Macular Degeneration.[6]

The different types of Vitamin B are essential for the nervous system and the brain. Specifically, they aid chemical signalling, enhance energy metabolism and create DNA and RNA.[7] [8]
A 2013 study examined the effects of Vitamin B1 (Thiamine) supplementation on fatigue during exercise on nine students who exercised for one hour a day, five days a week for four weeks. It concluded Vitamin B1 supplementation improves carbohydrate metabolism, creating more energy and delaying the onset of fatigue.[9]

Low Vitamin B2 levels can lead to mitochondrial dysfunction, which may cause migraines to worsen. A 2015 review examined eleven high quality studies (seven on adults and four on children) about the effects of Vitamin B2 supplementation on people with migraines. The results show Vitamin B2 can prevent the frequency and duration of migraine symptoms without any serious side effects.[10]

Although Vitamin B is mainly found in meat and fish, it does also appear in some citrus fruits, avocados, bananas, legumes, seeds and nuts, and dark leafy vegetables. That is why people who do not eat much fruit or vegetable are at risk of being Vitamin B deficient. Also, people who frequently consume alcohol are at risk of Vitamin B deficiency and should consider supplementation.[14] [15] [16]
Moreover, people with coeliac disease or on gluten-free diets may not have enough folic acid, Vitamin B12, and Vitamin B6 in their diets. That is why supplementing Vitamin B Complex is recommended for people who do not eat gluten.[17] [18]
