Focus on sustainability

Compact by Design. Certified by Amazon. Climate Pledge Friendly.

Small changes in product size and weight lead to lower carbon emissions.

We cre­at­ed Com­pact by Design to iden­ti­fy prod­ucts that, while they may not always look very dif­fer­ent, have a more effi­cient design. With the removal of excess air and water, prod­ucts require less pack­ag­ing and become more effi­cient to dis­patch. At scale, these small dif­fer­ences in prod­uct size and weight lead to sig­nif­i­cant car­bon emis­sion reductions.

Here are a few of the many ways products can qualify:

Less Packaging

Less air in container

More efficient shape

Waterless technology

    Set me back weeks , RUBBISH, Don’t buyBought these instead of Nutravi­ta Vit­a­min B12 due to them been cheap­er , What a mis­take that was, I take B12 due to fatigue after hav­ing a stroke a few years ago and i did start tak­ing H&B B12 and changed to Nutravi­ta Vit­a­min B12, Nev­er a tired day, Then a few weeks before run­ning out , I bought the weight­world B12 , Hon­est­ly , They set me back to a point that i was that tired , I was spend­ing the days in bed. Any­ways , Changed back to Nutravi­ta Vit­a­min B12 and with­in 2 days i am back to be hon­est , When you look at the tablet, They look fake unlike Nutravi­ta Vit­a­min B12 tablets. If i could have sent them back , I would have. I guess you get what you pay for, I would mark these 0 out of 10, Pho­to shows the dif­fer­ence in qual­i­ty of tablet

    Keep­ing HealthyAs I have only start­ed tak­ing B12 since yes­ter­day I can­not com­ment on how it affects me, but my rea­son for tak­ing B12 and for buy­ing B12 is to give me a boast of ener­gy and not feel­ing so tired, I have heard good results on tak­ing 12 and I bought a extra bot­tle for my daugh­ter, as she is 65 and I am 87, I feel that the B12 will help us to a bet­ter health and life

  3. Terez B.

    It is per­fect for me.Before I start­ed to take the vit­a­mins, I felt so tired, I was sleep­ing near­ly 10 hours a day, yet I would wake up tired in the morn­ing. I have tried a lot of things like chang­ing my diet, eat­ing more fruit and veg­eta­bles, drink­ing green tea, etc. but noth­ing helped me. So I decid­ed is time to try some­thing else. Now I feel great. Every­body is dif­fer­ent. Some­times it might take you time to under­stand what you body real­ly needs.

  4. Sian­Codes

    Works… so farSo I’ve giv­en this about two weeks. Before I start­ed tak­ing these I was tired all the time and had low iron lev­els despite tak­ing iron sup­ple­ments. I’m not veg­an but I do try to eat sus­tain­ably so veg­e­tar­i­an or veg­an meals most days. After read­ing the reviews I thought I’d try these to see what they’re like.After a week I noticed my ener­gy lev­els were high­er, instead of sleep­ing for 10–14 hours with ease and still being tired I am now sleep­ing maybe 8 hours a day and wake up feel­ing rest­ed… unusu­al for me.Its over 2 weeks in and ive start­ed night shifts at work again, im sleep­ing less than nor­mal (4–6 hours a day) and I’m not super tired like I would usu­al­ly be and the only con­clu­sion I can come up with is these tablets.They are super tiny so very easy to swal­low and the con­tain­er is FULL of them. They will clear­ly last a year and expiry date is well over a year.So far so good, can’t fault them.

  5. Ama­zon Customer

    Vit­a­min B12 and Dia­betes vital for healthOn research­ing B12 I was amazed to find that in the advice sheet in a pack of Met­formin, the main Type 2 med­ica­tion, it warns that the drug can lead to B12 defi­cien­cy which has side effects, some quite severe. Since start­ing to take B12 my blood sug­ar read­ings have dropped sig­nif­i­cant­ly. Do NOT take it at night if you want to sleep. Hope­ful­ly the effect will con­tin­ue by help­ing me to get my blood sug­ar down. Dia­bet­ics should not be Veg­ans. I have tried it and found my blood sug­ar went through the roof, but B12 brought it down.

  6. sue whit­tock

    Amaz­ing prod­uct !I’ve been strug­gling for months with debil­i­tat­ing fatigue, pain , aching joints etc , noth­ing the gp has giv­en me helped so went on an inter­net search , oth­ers said try b12 so after read­ing loads of reviews for var­i­ous brands I went for this one .I’ve been tak­ing them for 2 weeks now and I can hon­est­ly say hand on heart that these have changed my life . Hard­ly any fatigue or pain , my mood is lighter and I’m wak­ing ear­li­er . Maybe it’s a fluke but I’ll take it as I feel bet­ter now than I have for 2 years , rec­om­mend­ed 100%If you have fybromyal­gia or osteoarthri­tis like me it’s def­i­nite­ly worth a try x

  7. Bustablood­klaaart

    All GoodAs per title and tiny tablets for those who strug­gle with large ones.

  8. bray­gord jon

    B12 in tablet form? WhyThis is per­haps my fault- but why are these in a swal­low­able form?Its B12?The whole freak­ing point with B12 is that is you are short of it, the main rea­son is that you have a form of anaemia (per­ni­cious anaemia) due to a lack of ‘intrin­sic fac­tor’ in your gut- there­fore you can­not absorb B12.So B12 needs to be tak­en by absorp­tion under the tongue.SO WHY THE GIDDY HECK SELL SWALLOWABLE TABLETS!Thanks for wast­ing my time- and I am now well over­due for B12- per­haps if I crush these with a mor­tar & pes­tle & leave the gunk under my tongue they may be of some use?WHY!!!

  9. Ama­zon Customer

    They worked for me so much more ener­gyI don’t real­ly write reviews but after hav­ing a few real­ly bad days with no ener­gy i checked out google a few things it could be and vit­a­min b12 defi­cien­cy came up so thought I’d give it a try u ordered these read the reviews all good and bad but I thought I’d try for my self the day after tak­ing them I felt like a dif­fer­ent per­son. I had so much ener­gy I want­ed to leave an hon­est real review becuase I wouldn’t want any­body to feel like. I did and not order these because of some of the neg­a­tive reviews but they worked for me.

  10. Bri­an H

    does for me.Every 3 months I had to go to my doc­tors for a B12 injec­tion. Covid sprang upon us, so tried B12 tabs. Doc’s diid a blood test, and found my B12 up to scratch, so con­tin­ued with tablets.. These are small com­pared to what I was tak­ing, so hope they do the same job. That will show up in next blood test.
