Vitamin B12, otherwise known as Cobalamin, is a water-soluble vitamin that is stored in the liver within the body. Vitamin B12 can only be absorbed in the intrinsic factor (a protein produced in the stomach) is present. Without this factor, Vitamin B12 passes through the intestine and is excreted. The vitamin was founded in the early 20th century after the discovery of its deficiency disease, pernicious anaemia.
Vitamin B12 is available in four main forms called Hydroxylcobalamin, Methylcobalamin, Cyanocobalmin, and Adenosylcobalamin. This tablet contains the Cyanocobalamin form of vitamin B12. Once consumed, this form of Vitamin B12 is converted into either Methylcobalamin or Adenosylcobalamin, the two active forms of Vitamin B12 within the human body. Cyanocobalamin is produced from natural sources via the fermentation of Pseudomonas denitrificans.
Vitamin B12 is primarily known for its energy metabolism properties, reducing feelings of tiredness and fatigue. This is aided by the normal formation of red blood cells which carry oxygen around the body. In doing so, our immune system functions more efficiently. Additionally, Vitamin B12 also contributes to the normal functioning of the nervous system, homocysteine (an amino acid) metabolism, psychological function and the process of cell division.
At Oxford Vitality, we produce two strengths of Vitamin B12 to suit your purchasing requirements; 1,000mcg (1mg) and 5,000mcg (5mg). Both tablet concentrations are 6mm in size, a very manageable size to swallow. We also offer four strengths to allow flexibility when purchasing.
Please note - we recommend that both the 500 and 1,000 tablet options are more suitable for use by more than one person. This is to ensure that you are receiving full use of the product before its expiry date. For one person's use, we recommend the 120 or 240 tablet options.

great product really helping with my fatigue. Great service too really quick delivery
Ordered after going to the doctors with the nerve problem in my left hand became more pronounced and had a blood test taken.With my B12 first 3monthly injection due in over a week decided to order these as a precaution.Ordered in the afternoon arrived next morning by first class Royal mail.
Within 24 hours of taken a tablet the sensitivity in the hand decreased .When I had my B12 injection was informed that my levels was normal at 380.
So even though my levels of B12 was ok the tablets did seem to help after 2 weeks with the increased hand sensitivity.
At the price for 240 tablets with excellent delivery and price was well worth it.
Excellent. Very quick turnaround
All good pills
bought this product for my parents. Very good value for money, both of them are very pleased. Unfortunately it was out of stock when i waned to buy it for myself.

Great form of B12, this is methylcobalamin b12 its the best form. most of the stores sell cyanocobalamin b12, avoid that form of b12. speedy delivery and thanks for the gift you've added with my purchase.

Excellent vit B12, both my wife and myself have tried other products but not as good!
I love Oxford vitality vitamins I use this and their vitamin K2 as well as I am allergic.to a lot.of fillers and theIreland stuff is very natural and goos
I bought the Oxford Vitality B12, as it was the right form of B12, and also sublingual, meaning it's more likely to be effective. It's good value, and has less additional ingredients than some other forms. I take B12 every so often as I am vegetarian - as animal products are the only proper source , it's essential not to become deficient.
My order arrived well within allocated time. No problem taking tablets. No upset stomach as I have had with others. Can't fault them
Good subliqual tablet which is how b12 should be taken, under the tongue and dissolve
I only received mine today so can't comment on effectiveness, but the tablets are small, dissolve quickly, and they contain no sweeteners or flavourings. Looking at the short list of ingredients it's pretty simple to know exactly what you're ingesting, and I like that. The flavour is minimal and rather bland, so I'm not entirely sure why anybody would want flavouring anyway. The little pouches fit nicely through your letterbox which is pretty useful. All in all I'm very happy so far. I'll update if I change my mind.
Turned up the next day, only just started taking them and have seen an increase in energy but am hoping this will improve even more over time.
I used b12 and 3 month injection it help my condition livens me up
Very good product I take it regularly
Just diagnosed with parkinsons so have been feeling tired tried B 12 and I can honestly say I am feeling a lot more energetic so looking forward to seeing how the year progresses
excellent service and product
Came quicker then was stated which is great. Very good product and super neat packaging. Very happy with them. Will be getting more
usually pay a lot more than this, but good price and, yes, they do the job
Delivered on time, product as advertised, not broken in the package as some have said, very happy all round.
All good quick to arrive
Tried these due to feeling tired, etc used alongside other supplements and all together am feeling less tired. they arrived on time
Seem to stop me feeling as tired
I have bought these tablets a couple of times previously & find them good value. I'll definitely be buying them again.

Me, my family and my clients love them. Highly recommended.
