I'm still trying to wrap my head around all my SNP's and better understand the methylation process but am just not quite the braniac many of you are. I've been experiencing many of the symptoms of B12 deficiency, the worst being burning pain in my legs and feet. I take 1000 much of Solar sublingual methylcobalin, and have been for months, daily but it has not helped my symptoms. So at this point I'm not sure it is even b12 deficiency I'm experiencing. I do have several heterozygous SNPs for B12 absorption though. A recent lab test marked me at >2000 mcg when the range is 211-946. So my question is- Do you think I'm somehow not absorbing what i take and, if so, do you have any ideas on how to correct this? Or do you think I'm actually just taking too much and this isn't my problem. Thank you so much in advance for any help!
