Liquid B12 is a handy alternative if you do not enjoy swallowing tablets. Drops and sprays are simple to use, easy to carry and quick to add to your morning routine.
I spent several weeks comparing five popular UK options. I looked at ingredients, serving sizes, taste and ease of use. Nature Provides Bioactive Liquid Vitamin B12 came out on top, but each product suits a slightly different need.
Drops and sprays make it easier to choose a format that fits your routine.
Key Takeaways
- Nature Provides Bioactive Liquid Vitamin B12 is my top pick. It combines methylcobalamin and adenosylcobalamin with water and nothing else.
- BetterYou Boost is the easiest everyday spray. Four sprays provide 1200 mcg of methylcobalamin, with no measuring needed.
- Viridian is a strong runner-up. It also contains methylcobalamin and adenosylcobalamin, with 500 mcg per 0.5 ml serving.
- Healthspan stands out for flavour. Its blackcurrant spray provides 250 mcg per spray, making the serving easy to adjust.
- Solgar suits people who want more than B12. It combines cyanocobalamin with several other B vitamins in one liquid.
How I tested these liquid B12 supplements
Label clarity. I checked whether each brand clearly named the form of B12 and stated the amount per drop, spray or millilitre.
Ingredients. I noted added flavours, sweeteners and preservatives. A short list is useful for some people, while others prefer a flavoured product that is pleasant to take.
Everyday use. I compared the droppers and sprays, looking at whether the serving was easy to measure and practical to use away from home.
Servings per bottle. I counted how many stated servings each bottle holds, since bottle size alone tells you little once strengths differ. Prices move too often to compare usefully here, so check the current figure on the brand’s own page before ordering.
Claims. I focused on clear product details rather than dramatic promises, which matches the wider shift towards clear product information over marketing language in the supplement aisle.
What to know before choosing liquid B12
The NHS says adults need about 1.5 micrograms of vitamin B12 each day from food and other sources. Supplements often provide much larger amounts, so follow the product directions and ask a healthcare professional if you are uncertain about the right serving.
Methylcobalamin, adenosylcobalamin and cyanocobalamin are common forms found on labels. Methylcobalamin and adenosylcobalamin are forms used by the body, while cyanocobalamin is an established form used in many supplements.
The main advantage of a liquid is convenience. Sprays require no measuring, while droppers offer more control. Neither format should be treated as a replacement for medical advice or prescribed treatment.
If you eat little or no animal food, take certain medicines or are concerned about your B12 level, speak with your GP or pharmacist. They can advise whether testing or supplementation is appropriate.
Nature Provides Bioactive Liquid Vitamin B12

Nature Provides pros
- Contains methylcobalamin and adenosylcobalamin
- Water is the only other ingredient
- No added flavours, sweeteners or preservatives
- Provides 3000 mcg per 1 ml serving
- The 50 ml bottle contains 50 stated servings
- Dropper allows the liquid to be held under the tongue before swallowing
- Neutral taste with no sweet aftertaste
Nature Provides cons
- The unflavoured liquid may feel plain if you prefer sweet sprays
- The high-strength serving needs to be measured carefully
My experience with Nature Provides
This was the product I kept reaching for. Its label is unusually easy to understand, and the formula contains the two stated B12 forms with water and nothing else.
I liked how Bioactive B12 keeps the daily routine simple. Counting out the 13 drops was straightforward, and a full squeeze of the pipette gets you there in a few seconds. I could hold it under the tongue for the suggested 30 seconds without dealing with a strong flavour.
The neutral taste was a pleasant surprise. It reminded me of lightly mineral water and left no sweet aftertaste. Because each 1 ml serving provides 3000 mcg, I did take a moment to check the dropper rather than squeezing it into a glass without looking.
BetterYou Boost Vitamin B12 Oral Spray
BetterYou pros
- Four sprays provide 1200 mcg of methylcobalamin
- No dropper or separate measuring required
- Sugar free and sweetened with xylitol
- Widely stocked by UK pharmacies and health shops
- Clear directions on the packaging
BetterYou cons
- Includes flavouring, citric acid, potassium sorbate and green tea extract
- Also contains chromium chloride, which some shoppers may not want
- The stated daily serving requires four sprays
My experience with BetterYou
This was the easiest option to carry in a bag. There was no need to fill a dropper, and the bottle was quick to use when I was short on time.
The apricot flavour was mild rather than overpowering. However, the formula has more added ingredients than the minimalist drops. That trade-off may be worthwhile if a pleasant flavour helps you remember your daily serving.
Viridian Liquid B12 50 ml

Viridian pros
- Contains methylcobalamin and adenosylcobalamin
- Provides 500 mcg per 0.5 ml serving
- Dropper makes the amount easy to control
- The 50 ml bottle provides plenty of servings
- Clear serving information on the label
Viridian cons
- The base is not simply B12 and water
- Lower strength per stated serving than the top pick
My experience with Viridian
Viridian felt like the closest alternative to Nature Provides. Both come in 50 ml dropper bottles and contain methylcobalamin and adenosylcobalamin.
The 0.5 ml serving was easy to measure, and the 500 mcg amount may appeal to people who do not want the highest-strength option. It worked well as part of a morning routine, although its ingredient list is not as minimal as my top pick.
Healthspan Vitamin B12 Blackcurrant Oral Spray

Healthspan pros
- Uses methylcobalamin
- Provides 250 mcg per spray
- Pleasant blackcurrant flavour
- Easy to order directly in the UK
Healthspan cons
- Contains xylitol, flavouring, citric acid and potassium sorbate
- The 15 ml bottle is smaller than the dropper bottles
- Overall value depends on the number of sprays used
My experience with Healthspan
This was the most enjoyable flavour in the group. The blackcurrant taste made it easy to remember, and the spray worked neatly without requiring a separate measure.
The 250 mcg per-spray label also makes the serving easy to understand. Its ingredient list is closer to BetterYou than the minimalist drops, so it is better suited to shoppers who value flavour over a water-only base.
Solgar Liquid B12 2000 mcg with B-Complex

Solgar pros
- Combines B12 with several other B vitamins
- Provides 2000 mcg of B12 at the full stated serving
- Suggests 1 ml under the tongue, up to twice daily
- Widely available from UK supplement retailers
Solgar cons
- Uses cyanocobalamin rather than the two coenzyme forms
- The flavoured formula is not aimed at minimalists
- The dropper needs filling to the 1 ml mark each time
My experience with Solgar
Solgar is different from the other picks because it is a wider B-complex rather than a B12-only liquid. That can be convenient if you already planned to buy both types of supplement.
The liquid was simple to measure, although you need to decide whether one dropperful a day is enough or whether you want the second. Cyanocobalamin is an established form, but this product will not suit someone specifically seeking methylcobalamin and adenosylcobalamin.
Conclusion
Nature Provides Bioactive B12 is my top pick from these five. It combines methylcobalamin and adenosylcobalamin with water, without flavours, sweeteners or preservatives.
The clear label, neutral taste and 50 stated servings make it an easy product to understand and use.
BetterYou is the practical runner-up if you want an affordable spray that is widely available. Viridian is the closer match for shoppers who prefer a dual-form dropper with a lower stated serving.
Healthspan is worth considering when flavour matters most, while Solgar makes more sense if you want a wider B-complex. Whichever format you choose, follow the label and check the latest price before ordering.
FAQ
Do I need a B12 supplement if I eat animal products?
Not necessarily. Meat, fish, eggs and dairy contain B12, so many people get enough through food. Ask your GP or pharmacist if you are unsure or have concerns about your diet.
Is methylcobalamin better than cyanocobalamin?
There is no simple answer. Methylcobalamin is a form used by the body, while cyanocobalamin is an established form found in many supplements. Consider the complete formula, serving and advice from a healthcare professional.
What is the difference between B12 sprays and drops?
Sprays are quick and require no measuring. Drops offer more control and often come in larger bottles. The better choice is the format you find easiest to use consistently.
Why do B12 supplements contain large serving amounts?
Supplement servings are often much higher than the daily amount adults need from all sources. Follow the label rather than taking more than directed, and seek professional advice if you are uncertain.
