Diagnosis typically involves B12 level testing, intrinsic factor antibody tests, and sometimes specialized absorption studies like the Schilling test
B12 has many functions in our body, so unfortunately a deficiency will give rise to a wide variety of symptoms, like brain fog, memory problems, cognitive impairment, insomnia, headaches, especially migraine, behavioural changes, learning problems, nominal aphasia, mood swings, irritability, depression, anxiety, hallucinations, delusions, psychosis, peripheral paraesthesia (pins and needles), numbness, neuropathic pains, poor balance, reduced vibration sense or proprioception (joint position sense), tinnitus, ataxia, taste impairment, sometimes myelopathy, fatigue, anaemia (either with larger red blood cells, or with normal size of the red blood cells when there is also iron deficiency), other reduction in blood cells, abdominal complaints, malabsorption, failure to thrive, weight loss, diarrhoea, hyperpigmentation, glossitis, (aphthous) stomatitis, infertility, urinary tract infections, joint and muscle pain, muscle weakness, spasticity, seizures, cardiomyopathy, urinary and/or faecal incontinence, postural hypotension/dizziness, erectile dysfunction, to name a few
Recent research has broadened its applications beyond metabolism, highlighting its synergistic potential with NAD+ therapy for anti-aging and longevity benefits.[6][7] For instance, studies in adipocytes have demonstrated that 5-Amino-1MQ can increase NAD+ levels by 1.2 to 1.6-fold, suggesting a direct role in cellular rejuvenation.[8] This evidence prompted HyperCharge Health to incorporate NAD+ therapy with 5-Amino-1MQ, particularly for adults over 40, where NAD+ levels may have dropped by 50% or more.[9][10] At our clinics, we've observed patients reporting not just improved energy but also enhanced skin elasticity and reduced inflammation markers after combining these therapies
