B vitamins are a set of eight essential nutrients that play important roles in many bodily functions including supporting your metabolism, energy levels & the formation of red blood cells. 


Most well known for their role in energy production, B vitamins also play a role in mood & cognitive support - and are particularly important for vegans & vegetarians. 


Each of the eight B vitamins offers its own set of benefits, and by taking them together it allows them to work synergistically in partnership, which may help to improve overall efficacy.     

  

That's why many people are turning towards B complex supplements, which provide an easy and convenient way to help meet your daily B vitamin requirements. 


But with so many options out there, finding the most effective vitamin B supplement can be daunting, time-consuming, and even expensive. 


So we did the research for you. Complete with capsules, tablets & gummies – here are the top 5 vitamin B supplements worth trying. 


Why Are B Vitamins Important?

The family of eight "essential" B vitamins include thiamin, riboflavin, niacin, pantothenic acid, vitamin B6, biotin, folate, and vitamin B12, which all play various important roles in for daily wellbeing. 


Getting enough B vitamins can have a direct impact on your energy levels, mood, skin quality & brain function, amongst many other things. They're also the building blocks of a healthy metabolism - helping your body to break down food & convert it into energy.


B vitamins are water-soluble, meaning your body doesn't store them, so they need to be constantly replaced - either though diet or supplementation. 


While a healthy & balanced diet should contain all the B vitamins your body needs, some people are at risk of deficiency in one or more B vitamins. 


If you follow a restricted diet – for example not eating animal products – you may often find it particularly difficult to consume all the B vitamins that you need.

B Complex Supplements: 2025 Buyers Guide

A "vitamin B complex" is a term used to describe supplements that contain all eight essential B vitamins in one convenient daily product. 


Sometimes these products can also contain other vitamin-B-like nutrients, such as choline, PABA & inositol which can offer their own additional benefits. 


B complex supplements come in many different forms, ranging from tablets and capsules, through to drinks, powders, and even gummy vitamins.


Let's take a closer look at some of the other important things to consider when it comes to shopping for a quality product...

3 Things To Look For:

1

Sufficient Dosage

When looking for a vitamin B supplement, it’s important to ensure it contains as many B vitamins as possible (ideally all 8), and 100% of the recommended daily allowance (RDA) for each nutrient. 


Check the label to of any supplement and make sure it says “over 100% RDA” to help ensure you’re investing in a B complex that fully covers all of your nutritional bases. 


2

Absorbable Forms

Vitamins exist in many different forms, and some are better absorbed by our bodies than others. This means effectiveness can vary significantly.  


The form of vitamin B12 used in any B complex is particularly important in terms of quality. The most easily absorbed form is methylcobalamin which offers superior bioavailability - meaning you should ideally look for a supplement containing it. 


3

Satisfaction Guarantee

It's important that any manufacturer stands behind their product and is willing to give your money back if you aren't happy with the results. 


Many manufacturers now offer an extended returns policy or 100% satisfaction guarantee for as long as 30 or 60 days. 


This gives you plenty of time to try the supplement "risk free" to make sure it's what you're looking for.  

What To Avoid:

Fillers & Additives

Read the back label of any supplement carefully and watch out for any synthetic fillers or additives.

Avoid any unnecessary ingredients or bulking agents such as magnesium stearate, titanium dioxide, starch, iron oxide, or microcrystalline cellulose which don't offer any nutritional benefit.
