Vitamin B12 is beneficial during the winter months for several reasons. It is essential for boosting the immune system, improving mood, and providing an energy boost. Studies suggest that Vitamin B12 enhances the speed at which the immune system, including cytokine networks and white blood cells, addresses illnesses and infections, making it particularly relevant during the cold and flu season. Additionally, B12 has been linked to alleviating symptoms of depression and improving mood, making it beneficial in combating seasonal affective disorder (SAD) during the winter. B12 injections are also promoted to strengthen the immune system, increase energy, improve sleep, and boost metabolism, providing overall health benefits during the colder months.
