The table below lists each nutrient and their respective function for human health, along with examples of how these may be listed in the ingredient list on the label. ![](https://storebrandformula.com/hubfs/Design%20Files/Background%20Blobs/WhatsinBabyFormula-texture.png) ## Nutrients Nutrient Function Common Ingredient Name Example(s) Protein Protein is in every living cell and our body requires it from foods to build and maintain bones, muscles, and skin. Protein quality depends on an essential amino acid pattern. nonfat milk, whey protein concentrate Fat Fat is one of the key macronutrients that your baby needs for proper growth and development. In fact, fat provides about half the energy content of milk. There are different types of fat: monounsaturated; saturated; polyunsaturated; and trans fatty acids. DHA is a polyunsaturated omega-3 fatty acid that supports brain and eye development. coconut oil, safflower oil, soybean oil, palm olein Linoleic Acid Linoleic acid is a polyunsaturated omega-6 fatty acid. Linoleic acid is part of cell components and is used to produce signaling molecules in the body. linoleic acid ## Vitamins Vitamin Function Common Ingredient Name Example(s) Vitamin A Vitamin A supports good vision, a healthy immune system, and cellular growth. Beta-carotene is a type of Vitamin A derived from plants that acts as an antioxidant. vitamin A palmitate Vitamin D Vitamin D is an important nutrient for bone, muscle, and immune health. It plays a major role in calcium uptake and metabolism. cholecalciferol Vitamin E Vitamin E is an antioxidant for immune health and for healthy skin and eyes. vitamin E acetate Vitamin K Vitamin K helps blood clot and prevents excessive bleeding; low levels of Vitamin K can raise the risk of uncontrolled bleeding. Vitamin K deficiencies are very common in newborn infants. phytonadione Thiamine (Vitamin B1) Thiamine is an essential vitamin, meaning it cannot be produced by the human body and must come from the diet. Severe thiamine deficiency, known as beriberi, is almost unknown in developed countries like the United States. Almost all cells use thiamine. This vitamin converts food into energy. thiamine hydrochloride Riboflavin (Vitamin B2) Riboflavin is important for normal cell growth and activity. This vitamin supports growth and development and impacts skin, the lining of the digestive tract, blood cells, and brain function. riboflavin Vitamin B6 Vitamin B6 supports normal brain development and is important for the nervous system and immune health. pyridoxine hydrochloride Vitamin B12 Vitamin B12 is required for proper brain function and development. It also plays a critical function in nerves, blood cells, and many other parts of the body. Vitamin B12 deficiency in infants causes lethargy, failure to thrive, irritability, and poor brain growth and development. cyanocobalamin Niacin1 Niacin aids the digestive system, skin, and nerves to function properly. Niacin is also important for converting food into energy. niacinamide Folic Acid Folic acid helps your baby make healthy new cells and is critical to human health. For women, getting enough folic acid before and during pregnancy can prevent major birth defects of her baby's brain or spine. Folate Pantothenic Acid Pantothenic acid is required for growth and helps the body metabolize—or break down and use food. It is also required for producing fatty acids and plays a role in the production of hormones and cholesterol. pantothenic acid Biotin2 Biotin is a component of enzymes in your baby's body that supports healthy metabolism. It is required for growth and producing fatty acids. biotin Vitamin C Vitamin C helps tissue and bone grow and repair themselves. Vitamin C deficiency in infants causes lethargy, failure to thrive, irritability, and poor brain growth and development. ascorbic acid Choline2 Choline is naturally present in breast milk and supports brain and eye development. It is also a neurotransmitter that supports cellular signaling; prenatal choline plays a role in hippocampal (memory) development. choline chloride Inositol2 Emerging research suggests inositol may play a role in brain development. Inositol is also abundant in colostrum (the first breast milk produced during pregnancy) and mature breast milk. inositol ## Minerals Mineral Function Common Ingredient Name Example(s) Calcium Calcium is important for cellular signaling, protein stability, blood clotting, and muscle contraction. calcium carbonate Phosphorus Phosphorus is important for cellular signaling, energy metabolism, and structural components other than bone, such as DNA and RNA. potassium phosphate Magnesium Magnesium is a bone mineral component that plays a role in DNA and RNA protein synthesis, and cellular energy production. It also maintains cellular electrolytes and stabilizes membranes. Low magnesium is related to diabetes, heart disease, blood pressure, and osteoporosis. magnesium chloride Iron Iron is critical to oxygen transport and is a co-factor for enzymes in energy generation and neurotransmitter synthesis. This mineral also supports immune-cell health. Iron deficiency is the most prevalent deficiency in toddlers worldwide; iron deficiency can cause irreversible impairments to cognition. ferrous sulfate Zinc Zinc is central to DNA, RNA and protein synthesis. Zinc deficiency impairs growth, causes a loss of appetite, and is a major contributor to stunting growth worldwide. zinc sulfate Manganese Manganese is required for normal growth and health. This mineral is a part of several enzymes and helps your body break down fats, carbohydrates, and proteins. manganese sulfate Copper Copper is a co-factor for oxidation in several human systems: cardiovascular; immune; and neurologic (brain development). Copper also plays a role in skeletal and skin integrity. cupric sulfate Iodine Iodine is an essential component of thyroid hormones. After iron deficiency, iodine deficiency is the most prevalent among children. Deficiency or excess iodine causes goiter—thyroid gland excess growth—and cretinism, which is a condition of severely stunted physical and mental growth. potassium iodide Sodium Your baby requires some sodium because it supports nerve and muscle function. Sodium also helps maintain the right balance of fluids in the body. sodium citrate Potassium Potassium is a mineral and electrolyte that is essential for bodily function. When levels of potassium are not balanced, issues can occur, such as hyperkalemia and hypokalemia, muscle cramps, low blood pressure, and changes in heart rhythm. Potassium levels change with sodium levels to keep muscles working properly throughout your baby's body, especially your baby's heart. As sodium levels rise, potassium levels decrease. The reverse is true; as sodium levels decrease, the levels of potassium increase. potassium phosphate Chloride Chloride aids with digestion and works with other electrolytes, such as sodium and potassium, to help maintain proper body fluids. Chloride also moves fluid in and out of cells in the body. If chloride levels drop, it can cause dehydration. calcium chloride Selenium Selenium plays a critical role in human metabolism. Selenium deficiency allows some viruses to be more potent. sodium selenite ## Nutrients Select a nutrient to view more information: Nutrients Protein Fat Linoleic Acid Function: Protein is in every living cell and our body requires it from foods to build and maintain bones, muscles, and skin.
