There are many B12 deficiency signs and symptoms, including: Numbness Tingling, pins and needles Weakness, dizziness High homocysteine, low methionine Megaloblastic macrocytic anaemia Mild or moderate leukopenia (low white blood cells) Mild or moderate thrombocytopenia (low platelets) Enlarged red blood cells (macrocytosis) Abnormal white cell (neutrophils) Chronic fatigue or tiredness General weakness or lethargy General Signs and Symptoms: Ataxia, (unsteady walking) Paresthesia (prickling sensation) and weakness in peripheral nerves Confusion Infertility Vision loss Leg pains Shortness of breath Loss of appetite/weight loss Epigastric pain Osteoporosis Increased susceptibility to infection Failure to thrive in infants Vitiligo Premature greying of hair Burning feet Mental Changes Depression (including postpartum depression) Irritability Apathy Psychosis Sleepiness Suspiciousness (paranoia) Personality changes Memory loss Dementia, intellectual deterioration Hallucinations Violent behaviour Developmental delay and/or autistic behaviour in children Neurological signs and symptoms Abnormal sensations ie: pain, tingling, numbness of legs, arms, trunk A diminished sense of touch, pain and/or temperature Loss of position sense (awareness of body position) Weakness of limbs Clumsiness Tremor Symptoms mimicking Parkinsons disease or MS Spasticity of muscles Incontinence (urine or stool) Paralysis Vision changes Damage to the optic nerve neuritis, inflammation, atrophy Vascular Problems Transient ischemic attacks (TIAs) Cerebral vascular accident Coronary artery disease Myocardial infarction Congestive heart failure Palpitations Orthostatic hypotension Deep vein thrombosis Pulmonary embolism 7 Why is B12 deficiency often underdiagnosed
A single 10mL or 30mL bacteriostatic water vial can be used to reconstitute multiple peptide vials, as long as: Sterile technique is maintained at every syringe draw A fresh, sterile needle is used each time The vial is used within 28 days of first opening The vial is stored refrigerated after opening One 10mL bacteriostatic water vial can easily reconstitute 3-5 research peptide vials depending on reconstitution volumes used
Following these best practices helps ensure consistent dosing, reduced discomfort, and predictable results over time
