Supplement Description

What is Vitamin B12?

Vitamin B12 plays a vital role in our body's biological processes. It's important in the production of red blood cells and essential for cell replication. It also assists in helping our body convert food to energy.  B12 is particularly acknowledged for its benefits to the nervous system as well as the immune system.

Vitamin B12 is available in two forms - Cyanocobalamin or Methylcobalamin.

Why choose Methylcobalamin?

Methylcobalamin is the natural form of Vitamin B12. The body actually converts Cyanocobalamin into Methylcobalamin, which is the form the human body needs to function properly. This makes it more readily bioavailable - meaning it is more easily absorbed into the system.

What are the benefits of a Vitamin B12 supplement?

Vitamin B12 is a water-soluble vitamin which means that you need to consume it regularly in order to maintain adequate levels within the body. Further to this, as time goes by, vitamin B12 levels decrease in our blood, so older people may benefit by supplementing in terms of their general well-being. 

When combined with Folic Acid, vitamin B12 may help maintain the health of your heart, as together they are thought to help process levels of an amino acid called homocysteine.

Vegetarians and vegans may particularly benefit from supplementing with Vitamin B12 due to the fact that the main dietary sources are meat, diary, fish and eggs. In fact it's highly recommended as the potential for deficiency is very high among this group of people.

Symptoms of vitamin B12 deficiency include tiredness and fatigue, muscle weakness, memory and mood problems so if you're concerned you're not getting enough in your diet put a safeguard in place and top up with a convenient supplement.

Formulated for a direct route to the bloodstream

Just Vitamins Methylcobalamin tablet has been developed to allow sublingual administration (to be placed under the tongue and left to dissolve) if preferred. The tablet is blackcurrant flavoured, so tastes great too! You can of course, chew or swallow whole if you prefer, although sublingual administration is thought to offer the best and a more direct, and undisturbed route to the blood-stream.

Review Details
Service rating: Methylcobalamin sublingual form of B12, easy website, fast delivery, good product that melts fast under tongue, pleasant taste, recommended form of B12, effective to raise blood B12 in my case with possible gut absorption issues that didn't respond to ordinary tablets of methylcobalamin (that needs to be absorbed in gut) and nerve problems caused by covid (older person, messed up covid gut).
Product: raised blood B12 covid issues
Service rating: One of few places where you can buy methylcobalamine and NOT cyanocobalamin. Good sub-lingual tablet of b12
Product: Easy to use sublingual, normal taste, small tablet.
Good service and my blood test confirms healthy B12 levels
Pleasant tasting and dissolve easily under the tongue
Service rating: Great service, vitamins are nice and easy to swallow and taste great.
Product: Supplement is easy to take either **** or chew. Don't have a varied diet so take B12 to top up
Service rating: Website was good and service was great. Shame the tablets are of low quality.
Product: Poor quality methylcobalamin compared to other top 5* brands I am deficient in b12 so can tell right away if the b12 works.
Service rating: recommended by a pal, wasn't confident at first that they would work but gave it a try. Although it took a couple of months to kick in, eventually it began to make a difference. I am not so tired or lethargic anymore.
Product: I have quite a few conditions and take one medication in particular that depletes levels of vitamin B12. I am currently awaiting results of blood tests and believe I am going to see an improvement in my level of vitamin B12. Fingers crossed.
Really notice the difference in my health. I have more energy not sleeping all the time.
Service rating: I researched various companies and Just vitamins came across as being reasonable priced, comprehensive marketing, recyclable packaging, and quick and easy to order. Delivery was also fast and reliable.
As I was experiencing various symptoms of fatigue I thought I'd give B 12 supplements a go and Just vitamins seemed to be one of a very few that do B12 that dissolves under the tongue bypassing the gut, as I have IBS which can stop absorption.
Very happy with the company and the vitamin. I have reordered and will keep doing so.
Product: The Methylcobalamin is pleasant to take and dissolves easily, I take it because I have Ibs and the gut often doesn't absorb B12 well. I'm often exhausted and I've researched that B12 can help and is often depleted as we get older.
I've been taking it for over a year now and feel better and will continue to take it.
Service rating: Just Vitamins is my go to website for my vit B12 as they are the only place I have found that stock the melt in the mouth tablets. The website is easy to use with plenty of payment options. The tablets are reasonably priced and pleasantly tasty. Delivery is quick and communication with the customer is great.
Product: I was recommended these tablets by my chiropractor to help with my joint pain and fatigue. Since taking them my fatigue has greatly improved along with the condition of my hair and nails.
Service rating: Excellent service. Vitamins arrived quickly and in recyclable packaging. Pricing is good.
Methylcobalamin B12 tablets are small so easy to swallow and taste nice.
Product: Methylcobalamin B12 tablets are good for maintaining healthy B12 levels. The tablets are small and easy to take.
Service rating: For a long time I do buy my vitamins from Just Vitamins and the quality is top and service first class . I do recommend J.V. to many people.. Their products products keep me healthy.
Product: I never get cramps and helps for my heart and B12 for absorbing the vitamins.
Service rating: Easy to use website, competitive price, prompt delivery. Tastes great so what's not to love?
Product: It works, what more can I say?
Service rating: Super fast delivery. Website was recommended and was very easy to navigate.
Product: I love the ease at which my vits are dissolved under the tongue...and they taste great too!
Service rating: Would recommend just vitamins, easy to use website & quick delivery
Product: As someone with pernicious anemia & do struggle with energy levels towards the final 2 weeks before my b12 injection is due, taking these every morning does help & I do feel less tired/achey
Service rating: Muito bom! Achei o sabor bom e facilmente dissovível
Product: entrega rápida, deu tudo certo
quick delivery
Service rating: The service is about par with other companies in the field. but they were selling a particular type of b12 supplement that was difficult to find online ie mathylcobalmin; but I do not think much of the bags they come in as the bags seem to break easily about the seal: taken for peripheral neuropathy.
Product: Seems to have an affect, but of couse I have no actual proof, only the condition has lessoned, but does not prove it was this supplement, could have been coincidence or anything else.
Service rating: Website easy to navigate, quick to use. Product ok.
Product: Taste good, easy to take.
Service rating: I found Just Vitamins whilst looking for a clean source of Vitamin B12. I've been impressed with the product, and ordering and delivery were fast and efficient.
Product: I started taking B12 to improve my energy levels and this product has done exactly that, and it tastes good too.
Service rating: Excellent product - exactly as described
Product: Easily dissolved in mouth
Service rating: Website is easy to use, found everything I needed. Checkout and payment options are very clear and easy to understand and delivery is quick. Exceptional service!
Product: I take this supplement every day, I chew mine and it has a lovely flavour. I’m taking it to improve my general health and well being
Service rating: Rapid response and delivery after ordering. Website easy to use.
Product: Like this product, easy to take, dissolves under tongue, pleasant taste. Have used before.
Service rating: Although we were initially sent the wrong product, it was immediately replaced and we were sent a stamped, self-addressed padded envelope to return the first shipment. The product we ordered has a pleasant taste and is well packaged. It’s a bit too soon to comment on its efficacy.
Product: I’m taking this for Trigeminal Neuralgial. It’s early days as research indicates it can take up to 90 days for any improvement to be felt, but the tablets have a pleasant taste.
good service & the cleanest vitamin B12 I had found when ordered.
