In the role call of super supplements, B vitamins often don’t get the attention they deserve. But, for those in the know, B vitamins are the nutritional powerhouses responsible for the optimal functioning of our brain and nervous system. 

Therefore, B vitamins impact the body’s performance as a whole.


What Do B Vitamins Do?

B-complex vitamins are a group of water-soluble compounds and there are eight main ones; B1 (Thiamine) B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B7 (Biotin) and B9 (Folic Acid), and B12 (Cobalamin)

Cells depend on B vitamins for their proper development, particularly cells in the heart, liver and nerves. They also help convert food into energy, form red blood cells and enhance the immune system.

Vitamin B benefits the general health of your skin, bones, hair and muscle. It also helps for the optimal function of your bowels and intestines, for the improved health of your liver and cardiovascular system and for relief of moodiness and insomnia, from skin problems and from PMS.

How Do I Get B Vitamins?

B vitamins are not naturally stored in the body. Therefore, they need to be delivered, on a daily basis, from food sources or supplements

Good dietary sources of these vitamins include cereal grains, green vegetables, beans and peas, liver and some nuts. However, sometimes your diet isn’t enough.

Taking vitamin B supplements in pill or capsule form is a common way to increase your intake. These supplements are available over the counter and can provide precise doses of specific B vitamins.

IV therapy delivers vitamins directly into the bloodstream, bypassing the digestive system for quicker absorption. Intravenous vitamin B drips are often used for therapeutic purposes and can be customised to address specific deficiencies or health concerns.

Vitamin B12 injections are an effective way to increase B12 levels, especially for individuals with pernicious anaemia or malabsorption issues. These injections are administered by a healthcare provider.

As our levels of B vitamins have to be replenished daily, many of us are suffering from deficiencies in these valuable vitamins without even realising. This is especially true if you are following a stringent weight loss diet or, conversely, have high intakes of sugar, processed food or alcohol, way past the recommended daily allowance.

Other people at risk of B vitamin deficiencies include those suffering from stress or those on certain medications such as the birth control pill or HRT.


Which B Vitamin Should I Have?

B vitamins all play distinct roles and provide individual benefits. Here’s a list of what the most important B vitamins do:

  • B1Thiamine – converts food into energy, boosts the immune system and is a valuable defence against stress, eliminating irritability and mental confusion. It has been clinically indicated for use in Alzheimer’s and many anxiety disorders.
  • B2Riboflavin – works as a valuable antioxidant so useful in fighting the ageing process.
  • B3Niacin – is recommended for lowering cholesterol and is good for those suffering from circulatory problems. One study has discovered that niacin IV treatments are able to improve dietary fat storage in the body with its ability to suppress the metabolic process, known as lipolysis, in the visceral adipose tissue.
  • B6Pyridoxine – is effective in treating anxiety and depression and is often described as the ‘anti-stress vitamin’. This vitamin is also good for maintaining a healthy digestive system, improving skin condition and overall good health.
  • B7Biotin – more and more is being discovered about this vitamin, but it is important in pregnancy as it plays a valuable role in embryo development. Also good for the health of your skin, nails and hair.
  • B9 – also known as Folic Acid, this vitamin is recommended for pregnant women as it supports the growth of the baby and helps to prevent neurological birth defects. It is also good for fighting depression and preventing memory loss.
  • B12Cobalamin – fights depression, memory loss and chronic fatigue.

Experiencing fatigue? Consider vitamin B1. Worried about ageing? Then vitamin B2 is the one for you. Dealing with depression? Explore the benefits of vitamin B12 and B6. Expecting a baby? Incorporate B9 and B7 into your prenatal regimen. Having problems with high cholesterol? B3 may be able to help.
