Interestingly, studies suggest there may be a link between chronic inflammation and anxiety and depression ( 37, 38, 39). It is best to consult your doctor before taking any supplement. Your doctor will prescribe an appropriate dose based on your clinical condition. Many studies have also found a link between increased blood levels of vitamin D and a reduction in symptoms of depression, but the evidence so far is not very strong. Additional studies are needed ( 44). Cod liver oil is also one of the best food sources of vitamin D, which has an important role in maintaining healthy bones by regulating calcium absorption ( 9). Summary In fact, studies show that when accompanied by a diet high in calcium, taking a vitamin D supplement like cod liver oil can reduce bone loss among adults ( 19, 20).

While taking fish oil supplements like cod liver oil may reduce risk factors for heart disease, it’s unclear whether it can actually prevent heart disease or stroke ( 35). Thus, more specific research on cod liver oil and heart disease risk factors are needed to make a clear link between the two. Summary Breastfed babies from birth to 1 year of age should be given a daily supplement containing 8.5 to 10 micrograms of vitamin D to make sure they get enough. Formula-fed babies should not be given a vitamin D supplement until they're having less than 500ml (about a pint) of infant formula a day, as infant formula is fortified with vitamin D 2. How it reduces symptoms of depression is still unclear, but some studies suggest that vitamin D can bind to receptors in the brain and stimulate the release of mood-improving hormones like serotonin ( 45, 46). Summary

CONCENTRATION

The NRV of 5mcg for the general UK population includes pregnant and lactating women and population groups at increased risk of vitamin D deficiency. Your body can’t make them from scratch; they can be converted from alpha-linolenic acid (ALA), which is another omega-3 fatty acid, however this conversion can be inefficientvitamin D 1 and therefore it is best to make sure that DHA and EPA are included as part of a balanced diet. This is why both adults and children should aim to consume two portions of fish a week, one of which should be oily. Additionally, you can also top up your diet withregular supplementation with a cod liver oil food supplement. A source of Vitamin D Getting enough vitamin D from foods and supplements like cod liver oil is especially important for people who live far from the equator, as their skin doesn’t get enough sunlight to synthesize vitamin D for many months of the year ( 23). Summary Vitamin A has many roles in the body, including maintaining healthy eyes, brain function, and skin ( 7, 8).

Vitamin D supports the maintenance of normal bones and muscle function, and contributes to the normal function of the immune system. A source of Omega-3 Nevertheless, while omega-3 fatty acids help reduce symptoms of anxiety and depression, their overall effect seems small. Vitamin D is made by our bodies in reaction to sunlight on our skin. Most of us should be able to get vitamin D from sunlight from late March/April to the end of September. However, between October and early March we do not get any vitamin D from sunlight. In these months everyone should consider taking a daily supplement of vitamin D 2. How Much Do I Need? With the high levels of vitamin A in cod liver oil, keep in mind that the upper tolerable levels of vitamin A for adult males and females over 19 are 3,000 micrograms (mcg) retinol activity equivalents (RAE). Each tsp of cod liver oil contains 1350 mcg RAE ( 5).Cod liver oil is a great dietary source of vitamin D and may reduce age-related bone loss. That’s because it helps your body absorb calcium — which is a necessary mineral for strong bones — from the gut ( 9). Interestingly, studies also show that people who are deficient in vitamins A and D are at a greater risk of chronic inflammation ( 14, 15, 16). Summary By the end of the study, 39% of those who took cod liver oil comfortably reduced their use of anti-inflammatory medication by over 30% ( 25).

Cod liver oil, Omega-3 fatty acids, Vitamin A, Vitamin D, EPA, DHA, Methylparaben IP, Propylparaben IP In another earlier study in 58 individuals, researchers investigated if taking cod liver oil would reduce pain from rheumatoid arthritis enough to help people reduce their use of anti-inflammatory medications. Children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D 2.Unwanted Food or Drink Products - Once supply conditions are broken, there are a number of factors outside of our control that can affect the quality of a product. Therefore perishable goods such as food and drink cannot be returned. Cod liver oil is incredibly nutritious, with a single teaspoon providing 150% of the DV for vitamin A and 56% of the DV for vitamin D. Heart disease is the leading cause of death worldwide, affecting over 17.9 million people annually ( 32). Anxiety and depression are common conditions that together affect over 615 million people worldwide ( 36).

Studies have shown people who regularly eat fish have a lower risk of heart disease. This effect can be attributed to its omega-3 fatty acid content ( 33, 34). Two of the most important omega-3 fatty acids contained in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This is known as chronic inflammation, which is harmful and may increase the risk high blood pressure and several diseases, such as heart disease ( 10).Increasing HDL cholesterol: Omega-3 fatty acids in cod liver oil can raise HDL (good) cholesterol, which is linked to a lower risk of heart disease ( 35). As well as omega-3, cod liver oil is also a reliable source of important nutrients including vitamin A & D. These important nutrients play a crucial role in your body. Many studies have found that the omega-3 fatty acids in cod liver oil can lower inflammation and reduce symptoms of anxiety and depression ( 40, 41). Furthermore, other research has turned up mixed results. For instance, one review of nine studies found that omega-3 supplements had no significant effect on reducing symptoms of depression in older adults ( 43). More clinical and longitudinal studies are needed to better understand the effects of vitamin D on bone density in healthy children ( 21, 22).
