For vegans, an intake of vital nutrients not obtained through food is essential and vital. ApoLife 54 Vegan Complete provides all the important nutrients that vegans need daily. Calcium promotes the maintenance of strong bones. Iron contributes to the formation of red blood cells and hemoglobin, supports normal energy metabolism, and aids in oxygen transport throughout the body. Iron also helps maintain normal brain function. Zinc contributes to a healthy acid-base balance and a balanced carbohydrate and fatty acid metabolism. It promotes the growth of bones, hair, skin, and nails and strengthens our immune system. Selenium, a well-known free radical scavenger, protects cells from oxidative stress and contributes to normal thyroid function. Vitamin D3 supports our immune system. A vitamin D3 deficiency can also lead to a decrease in blood calcium levels. Vitamins B2 and B12 are essential nutrients for our bodies. They are involved in a variety of metabolic processes and particularly support our nervous system. Potassium contributes to normal muscle function and the maintenance of normal blood pressure. The added vitamin C contributes to normal psychological function and supports our nervous system.
