Vegetarian-friendly supplements provide essential nutrients that may be limited in plant-based diets, helping to maintain balance and vitality. Vitamin B12 supports nerve function and red blood cell formation, while iron ensures healthy oxygen transport to muscles and organs. At the same time, vitamin D and calcium work together to strengthen bones, and iodine helps regulate thyroid hormone activity. In addition, omega-3 fatty acids derived from algae contribute to heart and brain function. When combined, these nutrients help vegetarians sustain steady energy, mental clarity, immune strength, and overall wellness.
