Product Description
Progressive Labs B-12 Intrinsic Factor supports nervous system health, red blood cell production, and sustained energy levels. This essential water-soluble vitamin is vital for normal nerve cell activity, DNA replication, and SAMe (S-adenosyl-L-methionine) production—a compound that influences mood and emotional well-being. B-12 also plays a key role in metabolizing fats and carbohydrates for optimal energy utilization. As B-12 absorption naturally declines with age, supplementation helps maintain healthy levels and support overall vitality and cognitive function.
