Yes, MIC B12 injections are derived from natural compounds, making them safe for most individuals
It is composed of two protein subunits (alpha and beta) with attached carbohydrate chains, making it structurally more complex than a typical peptide
For example, vitamin B12 plays a direct role in DNA synthesis and cellular regeneration, including the turnover of skin cells
Additionally, a 2020 observational study published in the Journal of Dermatology and Dermatologic Surgery identified correlations between periorbital hyperpigmentation (dark circles under the eyes) and low serum ferritin levels an early indicator of iron deficiency

Adverse Reactions/Side Effects The following clinically significant adverse drug reactions are described elsewhere in the labeling: Drugs with Same Active Ingredient [see Warnings and Precautions (5.1)] Hypocalcemia and Mineral Metabolism [see Warnings and Precautions (5.2)] Renal Impairment [see Warnings and Precautions (5.3)] Osteonecrosis of the Jaw [see Warnings and Precautions (5.4)] Atypical Fractures Including Femoral Fractures [see Warnings and Precautions (5.5)] Musculoskeletal Pain [see Warnings and Precautions (5.6)] Patients with Asthma [see Warnings and Precautions (5.7)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice
