The Pharmacies compound weight loss medications with Vitamin B12 to support overall metabolic health during treatment. Vitamin B12 is essential for DNA synthesis, enzymatic reactions in metabolism, and the production of methionine—an essential amino acid vital for protein synthesis and cellular repair. It also plays a critical role in central nervous system (CNS) function and the myelination of neurons, supporting healthy nerve signaling. Calorie-restricted diets can increase the risk of B12 deficiency, so adding B12 helps maintain optimal energy, neurological health, and metabolic function.
