Should You Take B Vitamins?

Nearly 40% of people are deficient in one or more B vitamins, which are essential for maintaining energy, brain health, and overall well-being. B vitamins are responsible for the inner workings of almost every bodily function. They convert food into energy; they support red blood cell production. They even repair your DNA. If you're not getting enough, it would be no surprise you might be feeling sluggish or struggling to concentrate on simple tasks.

Vitamin B is actually part of a large family of eight B vitamins that each play a unique role in keeping your body functioning well. Combined, they're a powerhouse that helps to keep you full of energy, focus, and vitality.

Our experts break down the benefits, what to look for and The Best 5 Vitamin B Supplements in 2025.

Symptoms of Vitamin B Deficiency

Here are some common signs that your body may need a vitamin B boost:

Low Energy or Fatigue

You might be lacking some vitamin B1 (thiamine) and B12, which are essential for energy production.
Brain Fog or Poor Concentration

Find yourself doomscrolling on social media a little too often? Procrastination or lack of focus can be caused by a lack of B6 and B12, which are vital for brain health.
Digestive Issues

Yes, B vitamins are even beneficial for healthy digestion and nutrient absorption. Feeling sluggish or bloated? Check in with your vitamin B intake.
Brittle Hair, Skin, and Nails

Biotin is the superstar of nail health and B2 (Riboflavin) helps to keep your hair healthy and lustrous, and your skin glowing. Deficiencies in these nutrients can lead to weak nails, thinning hair, and even skin breakouts.
Mood Swings or Irritability

Are you hangry? Or just a bit B6 deficient? Vitamin B6 aids serotonin production. If you're suffering with deficiency, you may find you're more irritable or even suffer mild feelings of depression.

Benefits of High Quality Vitamin B Supplements

Vitamin B supplements can be a very effective way to boost your health and energy levels. Here are some key benefits:

Supports Energy Production

Vitamin B complex is essential for converting food into energy. B vitamins like B1, B2, and B3 act as coenzymes in metabolic pathways, helping your body generate ATP, its primary energy source.
Enhances Brain Function

B vitamins, particularly B6, B9 (folate), and B12, are vital for neurotransmitter synthesis and nerve function.
Promotes Cardiovascular Health

B vitamins such as B6, B9, and B12 help regulate homocysteine levels, an amino acid linked to cardiovascular disease when elevated.
Supports Healthy Skin, Hair, and Nails

Biotin (Vitamin B7) is renowned for its role in maintaining strong nails, shiny hair, and healthy skin.
Aids in Stress Management

Vitamin B5 (pantothenic acid) plays a role in adrenal function and the production of stress-related hormones like cortisol. Regular intake of B vitamins can help the body better manage stress and improve mood (Kennedy, 2016).

What To Look For?

Not all Vitamin B supplements are the same. It's important to choose quality, proven formulas from trusted brands to see real benefits.

Essential B Vitamins Look for formulas that include Vitamin B1, B2, B3, B5, B6, B7 (Biotin), B9 (Folate) and B12.
Choline While not technically a B Vitamin, it is just as essential and often grouped because of its similar roles in boosting overall health.
No Fillers There's no reason for your B Complex to have any fillers if its a good quality formula, so stay away from ingredients like Magnesium Stearate and Silicon Dioxide etc.
Money-Back Guarantee With many brands offering suspicious formulations, it is important to choose trusted, locally-manufactured brands that offer guarantees on their products. Leading brands sometimes offer a 30 or 60 day money back guarantee.

What Should I Avoid?

Amazon Sellers Lately there has been an increase in unscrupulous sellers pushing counterfeit or even falsely labelled formulations, particularly on third party marketplaces. We recommend going direct to trusted brands.
Insufficient Dosages Stay away from products that only offer 100% NRV - your body can't store excess so it is highly unlikely to overdose. A good quality supplement generally offers a high multi XXX% NRV of Vitamin Bs.
Products Without All Essential B Vitamins Some supplements don't include all eight essential B vitamins, which can limit their effectiveness. Always choose supplements that clearly include all B vitamins from B1 through B12.
