Thinking about taking a vitamin B supplement, but not too sure what the options are and which one’s best for you? 

Well, vitamin B actually refers to the vitamin B complex, which is made up of eight B vitamins. The entire vitamin B family is made up of vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate) and B12 (cobalamin).1,2 

Naturally then, trying to work out which ones to take for your specific health needs is going to be confusing - but it’s not that complex. Here’s what each one does…

Why is vitamin B important?

Each B vitamin is an essential micronutrient.2 This means that B vitamins play key roles in enabling specific pathways in your body and generating other important substances the body needs.2 These are essential for keeping your cells working properly and maintaining homeostasis (your body’s ability to keep you alive in a range of conditions).2 

So, in short, B vitamins are important for maintaining your body’s ability to keep you alive in a range of external conditions.2,3 Specifically:4
  • thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3) and pantothenic acid (vitamin B5) – help your body to release energy from food and support the proper functioning of your nervous system 
  • pyridoxine (vitamin B6) – supports your body to store and use the energy from protein and carbohydrates and to create haemoglobin, which transports oxygen around the body 
  • biotin (vitamin B7) – helps to make fatty acids 
  • folate and folic acid (vitamin B9) – help your body to create healthy red blood cells and reduce the risk of birth defects in unborn babies 
  • cobalamin (vitamin B12) – helps your body to release the energy you get from food, use folate (vitamin B9), make red blood cells and maintain a healthy nervous system 
Consequently, most of these ‘family members’ play a key role in helping your body metabolise food and manage its energy levels. Some studies even suggest that B vitamins are associated with slowed cognitive decline.4,5 

However, the only B vitamin the body can produce itself is biotin (B7), in small amounts, which is why we need to make sure we’re taking B vitamins – either through our food or supplementation.1

Our top B vitamin supplements

Solgar Vitamin B-Complex "100" Extra High Potency 100 Vegi Capsules

Vegan

Solgar

RRP £35.00

£28.00

£0.28/1 Capsules

Why we love it

Suitable for vegans, these vitamin B complex capsules from Solgar deliver an extra high potency 100mg formulation of key B vitamins. Containing all the B vitamins you need, they may contribute to the reduction of tiredness, support a healthy metabolism, and aid normal mental performance, among other benefits, for people with low B vitamin levels.6 

Solgar's unique formula delivers thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5) and vitamin B6, along with other B vitamins, such as folic acid, biotin (B7) and vitamin B12.
 

How to take

Although not dependent on dietary fat for absorption, it’s recommended to take the capsules with a meal.
 
Holland & Barrett High Strength Complete Vit B Complex 120 Tablets

Vegan

Holland & Barrett

£10.99

£0.09/1 Tablet

Why we love it

These tablets are an excellent source of B vitamins, containing B1, B2, B3, B5, B6, B9 and B12. 

They may support normal energy-yielding metabolism, red blood cell production and psychological function.7 Plus, they might help to keep your skin and hair looking healthy, as well as contribute to the reduction of tiredness and fatigue.4,7
 

How to take

These tablets are suitable for vegetarians and vegans. Just take two each day with meals.
 
BetterYou Boost Daily Vitamins B12 Oral spray (25ml)

Vegan

BetterYou

RRP £12.95

£9.32

£37.28/100 ml

Why we love it

As vitamin B12 is predominantly found in animal products, supplements are particularly recommended for those following plant-based or vegan diets. However, B12 deficiency is more common in those of advanced age or who have had certain types of gastrointestinal surgery, so it may also be useful for those people to take a B12 supplement.8

In quick and convenient, oral spray form, this vegan B12 supplement can help to ensure you’re getting the B12 you need for normal functioning.
 

How to take

Spray four under the tongue or inside the cheek for greater absorption.
 
Holland & Barrett Folic Acid 400ug 90 Tablets

Vegan

Holland & Barrett

RRP £4.25

£2.55

£0.03/1 Tablet

Why we love it

If you’re trying to conceive or are currently pregnant, the NHS recommend taking folic acid while trying to get pregnant and during the first 12 weeks of pregnancy. This is because folate is used by the body to make new cells during the early development of tissues and organs in the first weeks of pregnancy. 

As a result, taking folic acid may help prevent birth defects (particularly on the neural tube, which develops into the brain and spinal cord).10,11
 

How to take

One a day with a meal.
 
Floradix Vitamin-B Complex Liquid Vitamin Formula 250ml

Gluten free

Floradix

£17.49

£7.00/100 ml

Why we love it

This handy and convenient liquid formula provides the body with sufficient amounts of B complex vitamins, including vitamins B1, B2, niacin, B6, biotin and B12. 

Containing no alcohol, preservatives, colourings or artificial flavourings, this supplement is also free from lactose, yeast and gluten, which makes it suitable for vegetarians and vegans.

But just how can taking a B complex formula support your health? Let’s break it down: 
  • vitamins B1, B2, B6, B12 and niacin contribute to normal energy-yielding metabolism and healthy function of the nervous system
  • vitamins B2, B6, B12 and niacin contribute to the reduction of tiredness and fatigue6
  • vitamins B6, B9 and B12 help normal red blood cell formation.
Not bad for one supplement!
 

How to take

Adults should take 20ml once a day. Children aged 7-11 should take 10ml once a day and children aged 3-6 should take 5ml once a day.
 

The final say

Depending on your specific health needs, you may want to take a supplement that targets certain B vitamins. Or you may want to choose one that covers the entire vitamin B complex.
