I was previously taking Solgar's sublingual methococobalin (sorry, probably spelt wrong) and remember it making me feel a lot better with my brain fog, memory etc, but it didn't have any effect on my hair (still falling out unfortunately). After it ran out after 60 days there was a period of a month or two where I forgot to get some more, and I ended up getting Jarrow's methococobalin. Has anyone had this brand before? I'm taking one every day but am not feeling the benefit and wondering if I i should go back to Solgar . I can't remember off the top of my head but I think my last b12 result was around 100.
