Minerals- Minerals are very unique inorganic substances that work synergistically with vitamins and nutrients in the body to metabolize cellular reactions. Athletes with low Mineral levels can run into problems surrounding endurance, bone density, and muscle function.  That is why as an athlete it is crucial to have the correct levels of Minerals available for cellular functioning. Mineral nutrients, which the body cannot produce, must be supplied through proper diet.  Minerals are divided into two different classes; macro-minerals and micro-minerals.  Here we have outlined the optimum levels for athletes and non-athletes, in addition we also have information on deficiencies and what are good food sources to replenish a deficiency.

Macro-Minerals:

Calcium-Calcium is a critical mineral used by the body to strengthen the bones and teeth.  It also plays a role in nerve signaling and blood cell formation.  Athletes are advised to take Calcium to reduce the chances that they may have bone fracture.  There has been no direct correlation to Calcium intake and performance; however athletes often are advised to take Calcium supplements to reduce the risk of injury.  Specifically a bone fracture or break that may be career ending, hence athletes should ensure adequate Calcium intake to ensure proper bone density.

Calcium Guide

Elemental Symbol Ca
Average Dietary Intake Needed 1,000 mg/day
Athletic Dietary Intake Needed 1,400 mg/day
Functions Aids in normal bone development and bone strength, nerve signaling, muscle contractions, and cellular enzyme activity .
Where to Find Calcium fortified foods, dairy products, dark green vegetables
Signs of Deficiency Poor muscle function, low bone density, osteoporosis

Phosphorus- Phosphorus is largely involved compounds called ATP (adenosine triphosphate) which is the body’s main source of energy in muscular work.  Phosphorus is also used by the body for the development of healthy teeth and bones.  The majority of phosphorus in the body exists in a bound state with Calcium, known as creatine phosphate.  Because of phosphorus use in muscular work, studies have shown that athletes given supplemental doses have improved endurance and strength.  Serious athlete’s whose training is long and extensive should be sure their diet allows for adequate phosphorus intake.

Phosphorus Guide

Elemental Symbol P
Average Dietary Intake Needed 700 mg/day
Athletic Dietary Intake Needed 1,400 mg/day
Functions Main component in ATP, used for cellular respiration, aids in bone and teeth development
Where to Find Whole grain breads and cereals, foods with high protein content
Signs of Deficiency Loss of muscular strength, low bone density osteoporosis

Magnesium- Magnesium is a mineral that is needed in the body for over 250 cellular reactions in which food is converted into products used by the body.  Magnesium in essential for the human metabolism and the proper functioning of the nervous system. However, magnesium is easily lost from the body through sweat loss and it is important for athletes training in humid and hot climates to take careful note of their magnesium intake.  Magnesium supplements have been shown to increase physical performance and endurance.

Magnesium Guide

Elemental Symbol Mg
Average Dietary Intake Needed 375 mg/day
Athletic Dietary Intake Needed 650 mg/day
Functions Used in muscle contraction, synthesis of enzymes and proteins, aids in lactose digestion, and nerve signaling.
Where to Find Dairy products, whole great breads and cereals, dark green vegetables, fresh fruits
Signs of Deficiency Loss of muscular strength and cramping

Sodium- Sodium is most often used in the body to regulate water balance and pH levels of cells.  Sodium is important to athletes because it helps drive the urge to drink therefore maintaining proper blood volume.  Correct blood volume levels are key in athletic performance, they allow for the speedy removal of waste and delivery of nutrients to the cells. Due to the increased loss of fluids in athletes they are advised to consume more than the recommend amount of sodium, especially in humid or hot climates.

Sodium Guide

Elemental Symbol Na
Average Dietary Intake Needed 1.5 g/day
Athletic Dietary Intake Needed 5-7 g/day
Functions Used in Fluid balance, pH balance, and muscle contraction.
Where to Find Salty foods; pretzels, nuts, cheese, and chips.
Signs of Deficiency Loss of muscular strength, cramping, vomiting, and nausea.

Chloride- Chloride is used by the body to maintain proper fluid levels within cells.  It plays a key role in ensuring the normal blood osmolarity that is needed to carry out proper cell functioning. Like sodium, chloride is easily lost through sweating, so athletes training in humid or hot climates must take careful note of their chloride consumption.

Chloride Guide

Elemental Symbol Cl
Average Dietary Intake Needed 2.5 g/day
Athletic Dietary Intake Needed 3-5 g/day
Functions Used in Fluid balance, and pH balance
Where to Find Salty foods; pretzels, nuts, cheese, and chips.
Signs of Deficiency Cramping, vomiting, and nausea.

Potassium-Potassium in an intracellular electrolyte involved in nervous system functioning and muscle contraction throughout the body.  Potassium is easily lost through perspiration, and athletes who engage in sports with heavy fluid loss are advised to replenish their potassium levels as to prevent cramping and muscle failure.

Elemental Symbol K
Average Dietary Intake Needed 2.2 g/day
Athletic Dietary Intake Needed 3-5 g/day
Functions Fluid balance and nerve signaling
Where to Find Salty foods; pretzels, nuts, cheese, and chips.
Signs of Deficiency Cramping and vomiting

Micro Minerals:

Iron-Iron is the main component in the formation of red blood cells (hemoglobin) and muscle cells (myoglobin). Iron levels also show a connection between things such as immune system, learning ability, and attention span; individuals with low levels of iron have shown deficiencies in all of these processes.  Iron deficiency is known as anemia and often occurs during periods of growth because of the rapid growth of new red blood cells. Athletes with anemia experience shortness of breath and decreased endurance because of the lack of effective red blood cells. While iron supplements do not improve performance deficiencies almost always do.

Elemental Symbol Fe
Average Dietary Intake Needed 10 mg/day
Athletic Dietary Intake Needed 10 mg/day
Functions Aids in immune system, metabolism, and protein synthesis.
Where to Find Eggs, whole grain breads and cereals, various nuts, fish, and meat
Signs of Deficiency Loss of endurance and ability to heal wounds

Zinc- Zinc is used by the body for normal growth, wound healing, and proper immune system functioning.  Zinc also plays a key role in the production of natural antioxidants and in the removal of carbon dioxide from red blood cells. Normal zinc levels have been correlated with proper ability to recover from workouts.

Zinc Guide

Elemental Symbol Zn
Average Dietary Intake Needed 10 mg/day
Athletic Dietary Intake Needed 13 mg/day
Functions Aids in immune system, metabolism, and metabolism
Where to Find Meat, eggs, fish, various nuts, and vegetables
Signs of Deficiency Loss of ability to heal wounds and

Selenium- Selenium is used by the body to destroy free radicals that cause oxidative stress. Studies involving selenium have shown improved recovery and healing times in athletes who have normal levels of selenium.  However, high levels of selenium have been shown to be toxic so athletes should be cautious in monitoring their intake of selenium.
