The average diet supplies about 5 to 15 mcg/day of vitamin B 12in a protein-bound form that is available for absorption after normal digestion
With that in mind, we would like to voice our concerns over chronic implications following recovery from COVID-19, especially not only in diabetic but also in non-diabetic patients, and to indicate that some preventive measures could be undertaken by application of DPP-4 inhibitors
You're a strong candidate for B12 injections if you experience any of the following: Persistent fatigue that sleep doesn't fix Brain fog, forgetfulness, or trouble concentrating Low mood, anxiety, or stress that feels disproportionate to what's happening Weight gain or difficulty losing weight despite consistent effort Tingling, numbness, or weakness in hands or feet (signs of B12-related neuropathy) Frequent colds, slow healing, or post-COVID fatigue A plant-based, vegetarian, or vegan diet Age 50 or older (B12 absorption naturally declines with age) A history of gastric bypass, Crohn's disease, celiac disease, or chronic acid reflux Long-term use of metformin (for diabetes), proton pump inhibitors (Prilosec, Nexium), or H2 blockers (Pepcid, Zantac) An MTHFR gene variant or known methylation issue A history of B12 deficiency, pernicious anemia, or low folate Hormonal shifts: perimenopause, menopause, postpartum If you fit one or more of these, a vitamin B12 shot is one of the lowest-risk, fastest-acting interventions available
Its important to be aware, however, that lab tests for measuring B12 levels do not always tell the whole story
