Yet, deficiency is easy to miss, and the symptoms can be mistaken for other diabetes-related issues.<\/p>\n<p>Here are 6 reasons you should check your Vitamin B12 levels, especially if you take <a href=\"https:\/\/www.mayoclinic.org\/drugs-supplements\/metformin-oral-route\/description\/drg-20067074\" target=\"_blank\" rel=\"noopener\">Metformin<\/a> regularly.<\/p>\n<ol>\n<li>\n<h3><strong> Metformin Can Lower B12 Absorption<\/strong><\/h3>\n<\/li>\n<\/ol>\n<p>Long-term Metformin use interferes with Vitamin B12 absorption in the gut, potentially leading to deficiency after just a few years.<\/p>\n<p>If you have been on Metformin for over 2 years, B12 testing is strongly recommended.<\/p>\n<ol start=\"2\">\n<li>\n<h3><strong> Deficiency Mimics Diabetic Neuropathy<\/strong><\/h3>\n<\/li>\n<\/ol>\n<p>Tingling, numbness or burning sensations in the feet and hands are often blamed on diabetic neuropathy, but they could actually be due to B12 deficiency.<\/p>\n<p>Identifying the true cause means more effective treatment and faster relief.<\/p>\n<ol start=\"3\">\n<li>\n<h3><strong> Low B12 Affects Mood and Memory<\/strong><\/h3>\n<\/li>\n<\/ol>\n<p>Vitamin B12 is essential for brain and nerve health.
