Low B12 & Folate level. To be taken?

A serum B12 level of 226 ng/L (pg/mL) falls into the borderline/low-normal zone, while a serum folate of 2.0 µg/L indicates folate deficiency (though 50 days of 5 mg folic acid will have begun addressing this). Oral Supplementation: Sufficient for the vast majority of dietary deficiencies (such as vegetarian/vegan diets) or mild borderline states. Intramuscular (IM) Injections: Indicated if there are active neurological symptoms (tingling, numbness, balance issues, cognitive changes), diagnosed malabsorption (pernicious anemia, celiac disease, prior bariatric surgery, Crohn’s disease), or severe symptomatic anemia. Orally:--High-dose cyanocobalamin or methylcobalamin at 1,000 µg to 1,500 µg (1.5 mg) daily is the standard therapeutic regimen or 2 to 3 months, followed by a lower maintenance dose depending on diet. Injectabe--Typically 1,000 µg intramuscularly every alternate day or weekly for the first few weeks, tapering to monthly maintenance.
