Can help but...: B12 patches are relatively new and there's not much research. I found a study showing a formulation with ethanol (50%),oleic acid (10%) and propylene glycol (40%) was best absorbed: https://www.ncbi.nlm.nih.gov/pubmed/24310591 That's the good news;the bad is I haven't learned which product has that.I looked at some but none listed ingredients;might need to search B12 patches and ask the companies.
