Vitamin E is an umbrella term for a group of eight fat soluble compounds (tocopherols) that are found in a wide variety of wholefoods.  These compounds, of which alpha-tocopherol is the most biologically active, have a number of functions in the body. 

Vitamin E is an important antioxidant whose primary role in the body is to scavenge free radicals – these are rogue atoms or atomic groups that have lost at least one electron, forcing them to steal electrons from neighbouring molecules in the hope of stabilizing themselves.  Whilst unsurprisingly this can cause havoc in the body, vitamin E has the ability to neutralize these free radicals thus protecting the cells from oxidative stress.  Vitamin E deficiency is rare due to its ability, whilst working in concert with a number of other compounds (including vitamin C), to restore reduced levels of vitamin E in the body.  The richest source of vitamin E is wheat germ, other foods that contain significant amounts include eggs, nuts, sunflower seeds, cold-pressed vegetable oils and avocados.

Vitamin E contributes to:

·         the protection of cells from oxidative stress

·         the regeneration of the reduced form of Vitamin E

Also known as thiamin, vitamin B1 is one of the eight water soluble vitamins in the vitamin B family.  It is a vital human nutrient playing an important role in how we convert our food into energy – when we consume our food it is broken down into simpler units such as carbohydrates, fats and amino acids, vitamin B1 plays a crucial role in utilising these units to produce energy.  This is especially true for cells in the brain where the energy demand is really high which is why it is also referred to as a “morale vitamin” for its positive effect on the nervous system and a healthy mental attitude! 

Promoting the health of the nervous system, vitamin B1 helps in the proper development of the myelin sheaths around nerves, improving the body’s ability to withstand stress, it is often called the “anti-stress” vitamin and is also reported to improve the memory and powers of concentration.  Thiamin is essential to the body’s cardiac heath, involved in blood formation and helping in the production of the neurotransmitter acetylcholine which is used to relay messages between the nerves and muscles to ensure proper cardiac function.  Brewer’s yeast and liver are the richest sources of vitamin B1, however, spirulina, linseeds, rye, wheat germ and kidney beans are also important sources of this vitamin.

Vitamin B1 contributes to:

·         normal energy-yielding metabolism

·         the normal functioning of the nervous system

·         normal psychological function

·         the normal function of the heart

Next to calcium, phosphorus is the most abundant mineral in the body.  In order to be properly utilised it must be in proper balance with calcium and magnesium in the blood, these are the two minerals it works in tandem with to create strong bones and teeth, also helping to lay the foundation of a strong skeletal structure.  It is an essential part of our diet - especially as children when the most bone growth and development occurs.  Both DNA and RNA contain phosphorus which make it important for cellular reproduction. 

Phosphorus also contributes to the repair process and maintenance of various body cells which suffer from daily wear and tear, it makes up part of the phospholipids that surround cells - phospholipids help to protect and regulate what goes in and out of each cell.  Phosphorus plays an essential role in how the body stores and uses energy, it aids in the process of energy extraction by stimulating the process of metabolism of different nutrients including niacin(B3) and riboflavin(B2), helping to maximise the uptake of these two vitamins in particular.  The best sources for this mineral are chlorella, dairy, whole grains, legumes and nuts.

Phosphorus contributes to:

·         the maintenance of normal bones

·         the maintenance of normal teeth

·         the normal growth and development of bone in children

·         the normal function of cell membranes

·         normal energy-yielding metabolism

The importance of magnesium ions for all life itself, as well as for overall vibrant health, is hard to overstate.  Frequently referred to as the “miracle mineral”, magnesium is required to give the “spark of life” to metabolic functions involving the creation of energy and its transport, the creation and synthesis of proteins and is involved in literally hundreds of enzymatic reactions - it activates the enzymes that make copies of DNA and RNA making it essential in the process of cell division. 

Roughly half of your body’s magnesium is stored in your bones and acts as a cofactor with calcium and vitamin D to maintain and strengthen the bone structure and teeth (your teeth can only form hard enamel from calcium if magnesium is available).  It also works, again in concert with calcium, to regulate electrical impulses in the cells.  Cellular calcium channels allow the mineral to enter the cell only as long as needed to conduct an impulse, it is ushered out immediately by magnesium once its task is fulfilled, operating as a natural calcium channel blocker and responsible for relaxation, magnesium is pivotally important to the functioning of the parasympathetic nervous system.  Both magnesium and calcium are intimately involved with muscle function (magnesium relaxes, calcium contracts) with frequent muscle cramps being a symptom of a deficiency in magnesium.  If magnesium is severely deficient, the brain is particularly affected as magnesium is crucial to the production of neurotransmitters and the integrity of the blood brain barrier and therefore is needed to maintain normal psychological function.  The best food sources of magnesium include; avocados, chia and hemp seeds, sesame seeds, raw cacao and raw chocolate, sprouted nuts/seeds, sea vegetables (such as kelp and nori), raw green vegetables and grass fed dairy products.

Magnesium contributes to:

·         a reduction of tiredness and fatigue

·         electrolyte balance

·         normal energy yielding metabolism

·         normal functioning of the nervous system

·         normal muscle function

·         normal protein synthesis

·         normal psychological function

·         the maintenance of normal bones

·         the maintenance of normal teeth

·         Magnesium has a role in the process of cell division

Zinc is a metal that functions as an essential nutrient in the body, it is found in every cell and has been used since ancient times, with Ayurvedic texts dating as far back as the 14^th century recommending its application in various forms.  Although only required in limited amounts, zinc supports important bodily processes like strengthening the immune system – your body needs zinc to make T-cells, a type of white blood cell that fights off foreign invaders in your bloodstream.  With antioxidant properties, zinc helps to protect the cells in the body from damage by free radicals and supports the catalytic activity of various enzymes essential in DNA synthesis and cell division.  In males, zinc assists in spermatogenesis (the production of mature spermatozoa) and is a critical mineral for robust testosterone levels, in females it aids in all the reproductive phases including the birth and lactation stages. 

Zinc is an essential component of over 300 enzymes participating in the metabolism of carbohydrates, fatty acids, proteins and other macronutrients and has a regulatory role in vitamin A transport mediated through protein synthesis.  The intake of zinc has a positive influence on bone mass, it is an important cofactor in the stimulation of bone building osteoblasts (cells that synthesize bone), it accelerates the renewal of skin cells and it is essential for healthy nails and shiny hair.  Zinc is vital for vision with high concentrations found in the retina and may also protect from night blindness and prevent the development of cataracts.  This super nutrient also plays a crucial role in memory formation and cognitive stability, ensuring a proper intake of zinc is an important step towards optimal brain function.  Topping the list of zinc rich foods are oysters, however seeds such as chia, sunflower, hemp and pumpkin are also rich sources of this important mineral.

Zinc contributes to:

·         normal DNA synthesis

·         normal acid-base metabolism

·         normal carbohydrate metabolism

·         normal cognitive function

·         normal fertility and reproduction

·         normal macronutrient metabolism

·         normal metabolism of fatty acids

An essential trace mineral in the body, copper has long been known to play a role in human health – its use dates back to 400 BC when Hippocrates is said to have employed it as a treatment for a variety of disorders.  Playing a beneficial role in immune function, you need copper for healthy white blood cells – the cell type tasked with seeking out, identifying and destroying pathogens.  Low copper levels lower your white blood count leaving you vulnerable to infection. 

Copper is a vital element of the dark pigment melanin which imparts colouration to the hair and skin, intake of copper is said to protect greying hair.  Copper helps in the absorption of iron from the intestinal tract and releases it from its primary storage sites like the liver.  Also playing a significant role in the synthesis of haemoglobin, myelin and collagen, copper helps to protect the myelin sheath surrounding the nerves and is actively involved in the production of an element of connective tissue, elastin.  Functioning as a coenzyme for energy metabolism from the macronutrients in food we consume, copper enables a normal metabolic process in association with amino acids and vitamins.  Oxidative stress is a characteristic of copper deficiency, when obtained from dietary sources it acts as an antioxidant, getting rid of free radicals which can damage your cells and DNA.  For your body to use copper you need to have a balance of zinc and manganese which is why it is best to obtain your copper from dietary sources where it is already in bioavailable form.  Topping the chart as the best source of copper are oysters!  Closely followed by kale, shitake mushrooms, seeds, nuts and nut butters.

Copper Contributes to:

·         the maintenance of normal connective tissues

·         normal energy-yielding metabolism

·         the normal functioning of the nervous system

·         normal hair pigmentation

·         normal iron transport in the body

·         normal skin pigmentation

·         the normal function of the immune system

·         the protection of cells from oxidative stress

Derived from the Greek word for magic, manganese is a trace mineral that is present in tiny amounts in the body and is found mostly in the bones, liver, kidneys and pancreas.  It is essential for the proper and normal growth of the human bone structure and is a very effective mineral in aiding in the increase of the mineral density of spinal bone.  Manganese is also needed in the production and repair of connective tissue, its specific role is in the manufacture of mucopolysaccharides which are one of the main components of all connective tissues.  

Regulation of the body’s metabolism is another vital function of manganese with manganese activated enzymes helping in the metabolism of cholesterol, amino acids and carbohydrates.  Also a powerful contributor to the protection of cells from oxidative stress, manganese is a component of the antioxidant enzyme superoxide dismutase (SOD) which helps to fight free radicals.  Free radicals occur naturally in the body but can damage cell membranes and DNA, antioxidants such as SOD can help to neutralise free radicals.  Rich sources of manganese include; whole grains, nuts and nut butters and leafy vegetables.

Manganese contributes to:

·         normal energy-yielding metabolism

·         the maintenance of normal bones

·         the normal formation of connective tissue

·         the protection of cells from oxidative stress

Selenium is an essential trace element that plays an important role in a number of physiological processes in humans.  It is a key element in spermatogenesis (the production or development of mature spermatozoa) and male fertility.  Selenium has also been shown to support the immune system by promoting the production of killer T-cells (a type of white blood cell), which engulf and destroy harmful foreign substances that enter the body and could otherwise cause disease and infection.  Selenium works in close conjunction with vitamin E as an antioxidant to prevent the formation of free radicals which can weaken and damage cells in every organ system. 

In addition, research has shown that selenium is an essential component of the thyroid gland’s functions, helping to regulate the amount of the thyroid hormone T3 that is produced within the body – without selenium the T3 hormone cannot be produced which can be catastrophic to a wide variety of your body’s systems.  It is believed that good selenium intake can help to prevent hair loss and promote shiny hair and healthy nail growth.  Brazil nuts are the richest source of selenium discovered so far, also found in mushrooms, shellfish, garlic, pumpkin and sunflower seeds, selenium is destroyed when foods are refined or processed so eating a variety of whole, unprocessed foods is the best way to get selenium into your diet.

Selenium contributes to:

·         normal spermatogenesis

·         the maintenance of normal hair

·         the maintenance of normal nails

·         the normal function of the immune system

·         normal thyroid function

·         the protection of cells from oxidative stress

Potassium, the third most abundant mineral in the human body, is an essential mineral whose ions are vital for the functioning of all living cells!  Potassium plays a role at both the cellular and electrical level – considered and electrolyte because it carries a tiny electrical charge – it is found in red blood cells, muscles and bones.  Our bodies use potassium ions to conduct electrical impulses along muscle and nerve cells, it helps to boost the efficiency of nerve reflexes that transmit messages from one body part to another, this in turn helps in muscle contraction to perform various activities without tiring quickly. 

Potassium also has vasodilating properties that work to relieve the tension of blood vessels which is one of the main causes of high blood pressure.  It is helpful in reversing the role of sodium in unbalancing normal blood pressure thus acting as a vital component that maintains the normality of blood pressure in the human body.  The importance of potassium should not be underestimated in your dietary plan, most famously found in bananas other rich sources of potassium include spinach, avocados and coconut water.

Potassium contributes to:

·         normal functioning of the nervous system

·         normal muscle function

·         the maintenance of normal blood pressure

Forming 2% of total body weight in adults, calcium’s best known role is in bone and tooth health.  It forms a part of hydroxyapatite, the mineral complex that makes your bones and teeth hard and maintains bone density.  It is especially important that children consume an adequate amount of calcium to maximise their bone mass prior to adult years.  Also an important part of the blood clotting process, calcium works together with vitamin K and a protein called fibrinogen in the clotting cascade, without adequate levels of calcium and vitamin K the blood will take longer to clot.  Calcium helps your muscles contract in response to nerve stimulation, it activates a protein called calmodulin that your muscle cells need to provide the fuel they need to function.  Assisting in the transmission of neural impulses, the calcium in your body also aids other types of cell communication – it acts as a “second messenger” in your cells which means it responds to chemical signals from outside your cells and then triggers a response inside your cell. 

Calcium helps to activate several digestive enzymes and there is considerable evidence that calcium and vitamin D intake are influential in modulating energy metabolism in humans.  Like all minerals, calcium doesn’t work alone but in tandem with other nutrients such as magnesium and vitamin D, for this reason, obtaining our calcium from whole foods – foods whose nutrient profiles have been optimised by nature for superior absorption – is the best way to remain healthy!  Excellent natural calcium sources include; chia seeds, sesame seeds, seaweed (such as kelp and Kombu), dark leafy greens and dairy products (such as yoghurt, cheese and kefir).

Calcium contributes to:

·         normal blood clotting

·         normal energy-yielding metabolism

·         normal muscle function

·         normal neurotransmission

·         the normal function of digestive enzymes

·         Calcium has a role in the process of cell division and specialisation

·         Calcium is needed for the maintenance of normal bones

·         Calcium is needed for the maintenance of normal teeth

·         Calcium is needed for normal growth and development of bone in children

Iron is needed for a number of highly complex processes that continuously take place in the body on a molecular level and that are indispensable to human life.  Formation of haemoglobin is the chief function of this mineral – this is the primary protein found in red blood cells and represents about two thirds of the body’s iron.  Haemoglobin binds to the oxygen molecules that you breathe in from the air and releases them into your tissues.  The brain receives around 20% of the blood oxygen and a proper flow of blood to the brain can stimulate cognitive activity and help to create new neural pathways, it is especially important that children consume enough iron in their diet – iron deficiency in the first two years of a child’s life is associated with delayed cognitive and psychomotor development.  

Ribonucleic reductase is an iron dependant enzyme that is required for DNA synthesis (cell division), thus iron is required for a number of functions including healing and immune function - red blood cells are necessary for providing oxygen to damaged tissues, organs and cells.  Iron is also involved in food metabolism and is a cofactor and activator for some enzymes which play key roles in energy production and metabolism.  If iron stores are low symptoms can include tiredness, fatigue and dizziness.  Dietary iron has two forms, heme (animal based) and non-heme (plant based), important sources are; grass fed beef, oysters, spinach, lentils and beans.

Iron contributes to:

·         normal cognitive function

·         normal energy-yielding metabolism

·         normal formation of red blood cells and haemoglobin

·         normal oxygen transport in the body

·         normal function of the immune system

·         the reduction of tiredness and fatigue

·         normal cognitive development of children

·         Iron has a role in the process of cell division
