DHA(Docosahexaenoic Acid) is an omega 3 fatty acid. It is commonly found fish oil, cold water fatty fish and in seaweeds. DHA helps in reducing the risk of cardiovascular diseases because it decreases the level of triglycerides. DHA is a fatty acid that can be found in the brain phospholipids. DHA considered a brain food because it helps the brain to function well and prevents illness such as Alzheimer’s disease. It also helps alleviate the symptoms of attention deficit hyperactivity disorder (ADHD) and Raynaud Syndrome. It also helps improve moods and depression. It aids in preventing or reducing menstrual pains, and arthritis.

EPA (Eicosapentaenoic Acid), also known as icosapentaenoic acid and EPA, is a omega 3 fatty acid, a carboxylic acid which acts as a precursor for prostaglandin 3, thromboxane 3 and leukotriene 5 groups of eicosanoids. It is mostly found in fish oil, but can also be contained in human breast milk. In recent times, sources from microalgae have been preferred, due to the large quantities of toxins contained in fish swimming in polluted waters. Human body can produce EPA out of alpha linoleic acid, but since that ALA is an essential fatty acid, only excess amounts would be converted. EPA has been subject to studies pertaining to the use in treatment of schizophrenia, but it may also lower suicidal tendencies. Further use as breast cancer progression inhibitor is under investigation.

Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) that are considered to be an essential fatty acid. Omega 3 can be found in seafood and fishes such as tuna, and salmon. It is commonly known as fatty acid that is good for the heart. It also helps reduce the risk of cardiovascular diseases by controlling the cholesterol level and blood pressure level. It plays an important role in the efficient function of the brain. It helps in improving the cognitive functions of the brain such as memory and performance; and also aids in the behavioural function of the brain. It also fights fatigue, prevents diabetes, improves dry skin and blood circulation. It also prevents osteoporosis.

Vitamin A is a fat-soluble vitamin with known toxicity. Although its toxicity has been exaggerated, it is a factor worth keeping in mind. Carotine is converted in the human body to Vitamin A, it comes from vegetable sources. Vitamin A is necessary for normal growth and for skeletal development.

Vitamin D- The fast soluble vitamin D is perhaps the most underrated nutrient that is produced when sunlight touches the skin. But it is extremely vital for bone health, as without it the body cannot absorb the calcium that you may provide it in the form of supplements. With the advent of beauty products with high sun protection factor, this nutrient is becoming less available to our bodies. Even weaker sunscreens with just SPF-8 prevent the body considerably from producing vitamin D. Diseases such as arthritis, diabetes, certain cancers, multiple sclerosis, and even schizophrenia may stem from deficiency of this vitamin. You can provide vitamin D to your body through supplements and foods like mushrooms, tuna, eggs, dark green leafy vegetables, salmon, sardines, mackerel, fortified dairy products and cereals, yoghurt, and milk.
