Vitamin A is the name given to a group of fat-soluble antioxidant compounds.  Two different types of vitamin A are found in the diet; “preformed vitamin A” (also referred to as retinol or retinal) is found in animal products and “pro-vitamin A” is found in plant based foods - the most common type being beta-carotene.  It was the first fat soluble vitamin to be recognised and is sometimes referred to as the “anti-infective” vitamin due to its enhancement of the body’s immunity against infections by increasing the lymphatic responses against disease forming antigens.  It keeps the mucous membranes moist that line the mouth, respiratory passage and urinary tract and enhances the activity of white blood cells. 

Known as retinol because it produces the pigments in the retina in the eye, it enables your eyes to adjust to light changes, keeps the eyes moist and improves night vision.  It can also significantly reduce the risk of cataracts and macular degeneration.  Vitamin A helps to keep your body free from free radicals and toxins which might cause damage to your skin, helping to keep it soft and supple by ensuring moisture retention.  Vitamin A deficiency can impair iron metabolism which can lead to anaemia despite adequate iron intake.  Playing an important role in cells’ ability to adapt to perform specific functions in larger organs, the richest sources of preformed vitamin A are found in liver, kidney, butter and whole milk, whereas good sources of pro-vitamin A are dark green leafy vegetables and yellow-orange vegetables such as sweet potatoes and carrots.

Vitamin A contributes to:

·         normal iron metabolism

·         the maintenance of normal mucous membranes

·         the maintenance of normal skin

·         the maintenance of normal vision

·         the normal function of the immune system

·         Vitamin A has a role in the process of cell specialisation

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

Vitamin K is a fat soluble vitamin which is best known for its role in helping your blood to clot or coagulate properly by helping to form the proteins necessary for your bloods clotting factor.  The K comes from its German name “Koagulations” vitamin. 

There are two types of naturally occurring vitamin K; vitamin K1 (phylloquinone) which is found naturally in plants and vitamin K2 (menaquinone) which is made by the bacteria that line your gastrointestinal tract.  For proper bone growth and maintenance your body uses multiple vitamins, however, vitamin K and vitamin D work in tandem to produce a protein (osteocalcin) necessary for bones, without this protein minerals could not bind together to form the density of the bones.  Fermented foods, such as natto, typically have the highest concentrations of vitamin K found in the human diet followed by alfalfa seeds and dark leafy greens such as spinach, kale and cabbage.

Vitamin K contributes to:

·         normal blood clotting

·         the maintenance of normal bones

Vitamin C, a water soluble vitamin also known as ascorbic acid, is one of the safest and most effective vitamins whose benefits are many.  It is absolutely vital in collagen production – collagen is a simple protein and an essential part of our connective tissue – the very framework of our body.  All of the components that hold our bodies together such as skin, bones, blood vessels, teeth and gums, tendons and cartilage rely upon collagen.  Vitamin C is directly responsible for influencing collagen synthesis and helps to shield us from the symptoms of collagen deletion – most famously scurvy! 

A powerful antioxidant, vitamin C can protect cells from the damaging effects of free radicals which are harmful by-products of digestion or foreign substances in the atmosphere.  Inside the body it changes form to a negatively charged compound called ascorbate which helps to protect nerve cells and improves psychological function.  It has been known as the antioxidant’s antioxidant because it functions to protect vitamin E from oxidation too, another vitamin that interacts with free radicals to prevent cell damage.  Vitamin C strongly enhances the absorption of iron - when they are consumed and digested together, vitamin C combines with the iron to form a compound that is more easily absorbed.  Crucial to the overall health of the body in its efforts to fight off infections – both bacterial and viral – white blood cells contain 20 times the amount of vitamin C than other cells and require constant replenishment to keep the immune system working to its optimum capacity, especially during and after intense physical exercise.    Whilst highly concentrated in citrus fruits, other rich sources of vitamin C are acerola cherries, leafy green vegetables, red peppers and potatoes.

Vitamin C contributes to:

·         normal collagen formation for the normal function of blood vessels

·         normal collagen formation for the normal function of bones

·         normal collagen formation for the normal function of cartilage

·         normal collagen formation for the normal function of gums

·         normal collagen formation for the normal function of skin

·         normal collagen formation for the normal function of teeth

·         normal energy-yielding metabolism

·         normal functioning of the nervous system

·         normal psychological function

·         the normal function of the immune system

·         maintain the normal function of the immune system during and after intense physical exercise

·         the protection of cells from oxidative stress

·         the reduction of tiredness and fatigue

·         the regeneration of the reduced form of vitamin E

·         Vitamin C increases iron absorption

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

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

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.
