Elemental Breakdown

Your body is made up of over 60 Elements - these elements are found in larger than trace quantities. Any amount 0.01% or less is considered a trace element. See the breakdown below based on your body's mass.

Oxygen

Oxygen makes up 65% of your body's weight! Cellular respiration is the term used to describe the phase of the digestive process when food breaks down to supply cells with energy. During cellular respiration, cells use oxygen to break down sugar to produce ATP, or adenosine triphosphate. ATP is a molecule that supplies cells with energy.

Carbon

Carbon makes up 18% of your body's weight. It is the basic building block required to form proteins, carbohydrates and fats, and it plays a crucial role in regulating the physiology of the body.

Hydrogen

Hydrogen makes up 10% of your body's weight. It is the third most common element in our bodies and is a vital part of our tissue function. It even forms part of our DNA structure, making hydrogen indispensable to human life.

Nitrogen

Nitorgen makes up 3% of your body's weight and is found in many organic molecules, including the amino acids that make up proteins, and the nucleic acids that make up DNA

Calcium

Calcium makes up 1.5% of your body's weight and is the most common mineral in the human body — nearly all of it found in bones and teeth. It also plays a role in muscle contraction and protein regulation.

Phosphorus

Phosphorus makes up 1% of your body's weight and is found predominantly in bone but also in the molecule ATP, which provides energy in cells for driving chemical reactions.

Potassium

Potassium makes up .25% of your body's weight and is an important electrolyte. It helps regulate the heartbeat and is vital for electrical signaling in nerves.

Sulfur

Sulfur makes up .25% of your body's weight and plays an important role in the structure of the skeleton and muscles. It also is necessary in more than 300 essential metabolic reactions.

Sodium

Sodium makes up .15% of your body's weight and is an important electrolyte. It helps regulate the heartbeat and is vital for electrical signaling in nerves.

Chlorine

Chlorine makes up .15% of your body's weight and is usually found in the body as a negative ion, called chloride. This electrolyte is important for maintaining a normal balance of fluids.

Magnesium

Magnesium makes up .05% of your body's weight and plays an important role in the structure of the skeleton and muscles. It also is necessary in more than 300 essential metabolic reactions.

Iron

Iron makes up .0006% of your body's weight and is a key element in your metabolism. It is also found in hemoglobin, which is the oxygen carrier in red blood cells.

Fluorine

Fluorine makes up .00037% of your body's weight and is found in teeth and bones.

Zinc

Zinc makes up .00032% of your body's weight and is found in teeth and bones.

Copper

Copper makes up .0001% of your body's weight and is important as an electron donor in various biological reactions.

Iodine

Iodine makes up .000016% of your body's weight and is required for making of thyroid hormones, which regulate metabolic rate and other cellular functions.

Selenium

Selenium makes up .000019% of your body's weight and is essential for certain enzymes, including several anti-oxidants.

Chromium

Chromium makes up .0000024% of your body's weight and regulates sugar levels by interacting with insulin.

Manganese

Manganese makes up .000017% of your body's weight and is essential for certain enzymes, especially those that protect mitochondria — the place where usable energy is generated inside cells — from oxidants.

Molybdenum

Molybdenum makes up .000013% of your body's weight and is important for transforming sulfur into a usable form. In nitrogen-fixing bacteria, it is important for transforming nitrogen into a usable form.

Cobalt

Cobalt makes up .0000021% of your body's weight and is important in protein formation and DNA regulation.
