Cod Liver Oil 1000mg. Cod liver oil is ‘natures gold’ because it is so good for so many functions in your body. One of the healthiest supplements you can take.
Cod liver oil is obtained from the liver of the cod. Cod liver oil and other fish liver oils are rich sources of vitamins A & D; they are also rich sources of the omega-3 essential fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Function/ Used for
EPA and DHA are found in every cell membrane in the body and have a wide range of functions. Their health benefits include: (1)
EPA and DHA also inhibit the production of inflammatory chemicals in the body and have an anti-inflammatory effect in their own right. Fish body oils and fish liver oils are widely used in the management of inflammatory joint conditions. (2)
EPA may also help to discourage the formation of blood clots and help assist the blood to flow freely around the arteries, maintaining the circulation. EPA may also help maintain a healthy heart.
DHA is important in infant development, particularly in prematurely born infants. It is believed to be necessary to early eye and brain development. DHA is also thought to support brain development throughout childhood.
Omega 3 fatty acids also help maintain suppleness.
The European Food Safety Authority (3) makes recommendations for EPA and DHA intake, substances which are found in fish oils:
250mg of EPA/DHA per day for adults and children over the age of 2.
100mg DHA per day for infants and young children aged 7-24 months.
· 100-200mg DHA per day in addition to general adult requirements for pregnant and lactating women from fish body oils (fish liver oils should be avoided. See ‘use in pregnancy and breastfeeding’).
Take one capsule a day with water for adults and children over 10.
As a supplement
Cod liver oil and other fish oil supplements are available as capsules and liquids. Food supplements generally provide 100–1500 mg combined EPA/DHA per dose. The dose is not established but doses of 1000-3000mg daily may be adequate.
