Hi
I'm just adding to the posts about bad batches of B12 - there's been a couple in the last month.
I have self-injected since 2020 - originally every other day, increased to every day after having Covid in July 2021. Taking control has felt miraculous as I have been able to return to full-time work, cycling and hiking. I still find aerobic exercise knocks me back but I really feel that the knowledge I've gained through using this Forum has given me my life back.
After such a positive improvement I've had a huge return of symptoms over the last six weeks - my usual suspects are tinnitis, paresthesia, numbness in my feet and hands, and fatigue. At first I thought I'd picked up a bug - tiring easily and some breathlessness. When I didn't improve I went to the GP and blood tests didn't show up any problems (lots of tests - including folate, magnesium, ferritin, thyroid). It was getting clearer that my symptoms were very similar to when diagnosed and I couldn't understand what would cause their return. I've felt really concerned. I began to suspect it could be the batch but it just seemed so unlikely.
Then, at the end of last week I went away and I'm suddenly feeling well again. Some tingling and tinnitis remain but my energy is much better and I am not numb. On coming home I've checked and the ampoules I took are a different batch number - left over from a previous order as I keep a 'going away' bag with all I need.
I moved to Pascoe Vit B12 Depot when I couldn't get hold of Panpharma - I've been really happy with it and wondered if the larger ampoules were beneficial. However, this batch (1421) seems not to be working for me at all. I know getting away and being relaxed helps - but it seems too much of a coincidence to not relate it to the batch. The timing of the symptoms returning also seems to correlate with my last purchase.
I'm mentioning it here because it's so difficult to work out what's going on as there are so many factors affecting our health. I thought it might be helpful to mention my experience to support others who are also wondering whether it could be a faulty batch.
I don't remember reading about bad batches previously but there have been a couple this month and I wonder if there has been an increase in problems - but I don't know why that would be. There wasn't any hold up on my order - it arrived very quickly. I've ordered some Panpharma now - hoping it arrives quickly! It does put me off buying the boxes of 100 now in case this happened again.
