Vitamin B12 1000mcg - 400 High Strength Vegan Tablets - VIT B12 Methylcobalamin - 13 Month Supply - Made in The UK - Nu U Nutrition

TLDR: great for overall energy boost, quick dissolving, good value.Got good general B12 benefits off these; primarily boosted energy, maintained focus on cognitive tasks and elevated mood. Effects pretty swift after taking and sustained over several consecutive days. Think this is a good general booster in a good form.Specifically with this brand and this tablet: the tablets are small sublinguals which lean very towards the sweet end of the taste spectrum (a previous brand I tried, Jarrow I think, were a little sharper and more tart). These dissolved very quickly, in under 30 seconds I'd say. Again comparing to the previous brand - those were harder tablets which took longer to dissolve, around 60-90 secs. Ultimately not a massive deal-breaker either way for me, both were palatable.The main factors that would influence me mostly would be price / value and effectiveness. As I wrote earlier, the effects were good and generally uplifting as standard for B12. Regarding price these were decent quantity for the money at the time of purchase, so I'm happy with the return on my investment.I have bought other pills from this brand before and do take advantage of their offers from time to time, so when factoring that in, my overall savings on supplements is one that I'm happy with. So that would be another factor that would make me likely to lean towards buying this again next time.Ultimately a decent choice and purchase for me; happy with the effectiveness and value for money.

This is a great and much needed product.I had been taking Ompremazole to suppress the production of stomach acid for many years and my health has deteriorated; in particular, I could not get rid of a chronic and intense feeling of being tired. It turned out that Omeprazole and other antacids reduce the absorption of vitamin B12 by the gut to such an extent that the amount even in B12-rich foods and normal vitamin B supplements may not give you enough and you can develop symptoms of potentially fatal pernicious anaemia.This is a condition where the body cannot make the haemoglobin that carries oxygen around the body or the cytochromes that play an essential part in the respiration of every living cell as well as many other essential metabolic processes.The reason that you need stomach acid to absorb B12 is that it combines with a substance called intrinsic factor secreted by the stomach only in the presence of acid, This is carried with your food to the small intestine where it is absorbed against a concentration gradient by an active transport mechanism. This allows you to absorb adequate vitamin B12, even from foods which may contain relatively little and you do not develop pernicious anaemia.When I Googled the symptoms of pernicious anaemia, I discovered that I had the lot! Not good news.Enter Vitamin B12 from U Nutrition. This gives massive doses of vitamin B12 (about 100 times more than in regular vitamin B supplements). This allows the vitamin B12 to enter by passive diffusion along a huge concentration gradient, either through the gut or through the tongue. It works best via the tongue since it dissolves completely in just a tiny amount of saliva, which gives a higher concentration gradient than if it were dissolved in the relatively large amount of food present in the intestines.Still the proof of the pudding is in the eating. I found that after taking these tablets at the rate of two or three a day for 4 days, I was feeling a lot better and my blood oxygen levels measured with a pulse oximeter went up from being so low that it set off the alarm I to being normal.What more can I say except that I intend to keep on taking the pills.

Have been taking these for years.Nice and small and easy to swallow.Only complaint is the container is unnecessarily large as the tablets don't even come up to the half way mark. Why do this?

Reasonable deluvery time, but I am here to talk about the actuak product! For what feels like forever now I have felt CONSTANTLY tired. Even after a good sleep of 6-8 hours and complete rest, I would wake up tired, go to sleep tired and feel tired throughout my day. I just accepted that I was just over running myself. My doc prescribed anti depressents/anxiety pills saying there was likely a lack of serotonin in my system. Then I spoke to a colleague who had been struggling to sleep but didn't want to take sleeping pills. Her doc recommended some vitamins/suppliments including B12. She told me she'd been sleeping a lot better since and didn't feel tired near as much as before. Like me she suffered from dark circles all around her eyes, no matter how welk rested I have been I have always had dark circles (see pic) and her circles had started lightening off a bit after a few weeks.I did some research of my own as I skeptical of vitamins as my parents told me that you're essentially paying for expensive p**s if you take them. Having looked into it further, a medication I take called Metformin for diabetes, has a side effect where it actually significantly reduces your B12 levels. On top of this most people are actually B12 insufficient anyway because it is not something we come by often in our normal diets, not in the amounts our bodies require.So I decided I would try them to see if I would feel a difference. It said you'd see results immediately but I figured I'd have to at least take them for a few days before feeling the benefits. Wrong. As soon as I started taking them I felt HEAPS better! After a couple of weeks just taking one a day (they taste really nice btw) I have BAGS more energy, I am not waking up tired anymore and I have even started to see a lightness around my eye circles!! (pic 1 is after the tablets, pic 2 where i am wearing a blue blanket is before taking) I have come off my anti depressants. 10000000000% worth their salt! If you are tired and run down a lot, but skeptical, just get them. Honestly. Life changer.
