Novel methods for isolating fish roe/egg extracts, notably a coagulum and a sediment extract, enriched in phospholipids and omega-3 fatty acids are described. Novel compositions comprising omega-3 polyunsaturated fatty acids and micronutrients, which may be used for the management of neurological conditions such as ADD-ADHD, autism, cognitive impairment, and mood disorders are also described. These compositions are homogenous compositions comprising effective amounts of omega-3 fatty acids in microencapsulated or emulsified form, and/or from the sediment extract from fish roe/egg, vitamin B6, magnesium, zinc and copper, and may further comprise additional ingredients such as folic acid (e.g., L-methyl folate) and gamma-linolenic acid (GLA).
