Experts say, The unique chemical makeup of Vitamin B12 and iron explains their different roles in our bodies. Cobalamins complex structure allows it to participate in methylation reactions and DNA synthesis, whereas irons role in hemoglobin is critical for oxygen delivery to tissues. Dietary Sources of Each Nutrient Vitamin B12 is mainly found in animal products like meat, poultry, fish, seafood, eggs, and dairy
It is also important to note that different conditions affect HbA1c in different ways: Haemolytic anaemia and acute blood loss shorten red cell lifespan and tend to lower HbA1c Iron deficiency anaemia is associated with increased HbA1c, likely due to prolonged red cell survival Haemoglobin variants (haemoglobinopathies) can cause variable or assay-dependent interference the effect depends on the specific variant and the HbA1c method used B12 or folate deficiency alters erythropoiesis and red cell indices, making HbA1c potentially unreliable in either direction Clinicians should therefore: Review the full blood count (FBC) alongside HbA1c Check serum B12 and folate when anaemia or macrocytosis (raised mean corpuscular volume, MCV) is identified Consider alternative glucose assessment methods specifically fasting plasma glucose or a 75 g OGTT for diagnostic purposes, or self-monitored blood glucose (SMBG) or fructosamine/glycated albumin for interim monitoring when HbA1c is unreliable Not sure where to start
