Omega-3 fatty acids are considered essential fatty acids for health. They should be consumed in adequate amounts in the diet or possibly supplemented with over-the-counter preparations. They should not be supplemented in large doses without consulting a doctor as they also carry side effects.
People who do not consume PUALP supplements are less likely to get sunburn (but no less than popular sunscreens)The effect on reducing symptoms of Crohn's disease, ulcerative colitis, asthma has also been studied, but results are mixed and inconclusive. Polyunsaturated fatty acids are essential for the development of normal vision. People who consume them in adequate amounts have a lower risk of vision loss. Very importantly, supplementation and a diet rich in omega-3 seems to reduce the risk of developing prostate cancer, colorectal cancer. And also slow the progression of colon cancer in the early stages of the disease. Supplements with omega polyunsaturated fatty acids are available over-the-counter in pharmacies and also markets. They may be in capsule form. They are also contained in preparations of cod liver oil, linseed
It is important to buy omega-3 fatty acid supplements produced by recognised pharmaceutical companies, as preparations from unknown sources may contain heavy metals such as mercury, lead and cadmium. Supplements vary in the amounts and proportions of fatty acids. Some are specially formulated for infants and children (e.g. drops, syrups). However, these should not be used without consulting a paediatrician. Adults should not take more than 3 - 4 g per day of omega-3 fatty acids, because of the increased risk of bleeding.
On average, fish oil capsules contain 30% om ega-3 fatty acids (i.e. per 1,000 mg of fish oil, there is approximately 300 mg of omega-3 fatty acids). The recommended dose is 1 g per day, so 3 capsules per day should be consumed. There are also supplements with a higher content of omega-3 fatty acids.
