    and feel it is good
  • 29-Mar-2019

  • 03-Mar-2019

    A very good product for treating depression.
  • 22-Feb-2019

    With in days I felt the benefit of these tablets. More energy and more alert. Easy to take, dissolving under the tongue quite quickly. No after taste just a little gritty but that soon disperses.

    I find that this B12 supplement is more effective than any others I have tried

    These are the best b12 supplements I have found. Free of sugar, flavourings, colourings etc, and they dissolve well under the tongue.
  • 12-Jan-2019

    Excellent product, essential in a vegan diet
  • 02-Jan-2019

    Bought it several times. Great
  • 17-Dec-2018

    Great source of B12, it’s more effort to take the supplement due to taking it under your tongue for it to dissolve, but you get used to it.
  • 15-Dec-2018

    I have taken this vitamin for several years too,t dissolves quickly and leaves no after-taste.
  • 12-Dec-2018

    Ensure I take this every day especially as I am a vegan.

    Product works. Easy to take and quick to dissolve which is what i wanted
  • 06-Oct-2018

    I was looking for a B12 supplement to support my vegan diet - one that had been developed taking into account dose required, how it's best absorbed and what is is made from.
    This product ticked all the boxes.
  • 22-Sep-2018

    Excellent product! Highly recommended.
  • 05-Sep-2018

    Good product. Easy to take and works for me.
  • 02-Sep-2018

    dissolve under the tongue... does go a little messy in your mouth for a few minutes but does eventually dissolve... best form of B12 (methyl) and very cheap

    Feeling much better would recommend
  • 29-Jun-2018

    Great, sleeping better since the first night that I took it.
  • 28-Jun-2018

    As, probably, with a lot of these things, I don't feel any different, but being on a vegan diet have more peace of mind that I am not missing out on B12.
  • 25-Jun-2018

    If you have Lyme disease, or are recovering from it, this is a must!! I took sublingual normal B12 as I realised it is low when you have Lyme, but I didn't realise you can't absorb it properly. No such problems with this! I'm slowly getting my life back. I have a spare bottle now to ensure I don't run out. No...

    Easy to take as it is sublingual
  • 15-Jun-2018

    suits our son who has multiple allergies
  • 10-Jun-2018

    This tablet has to be dissolved under the tongue. I don't find this easy and it hangs around in my mouth for over half and hour. That is a long time not to be able to swallow.
  • 07-Jun-2018

    I have only just commenced using the Vitamin B12 Tablets.
  • 19-May-2018

    It's the best product we have found.

    Lyme disease left me with serious energy deficit problems. This form of B12 was recommended. Not THE answer but used alongside a number of other supplements to address the deficiencies it causes, well I am slowly getting my life back. Can't thank you enough because the price of purchasing these from...
