Complete Omegas blends the essential omega 3 and 6 fats which must be sourced from the diet or supplementation, along with omegas 7 and 9. The key omega 3 fatty acids EPA and DHA, contribute to many aspects of cardiovascular health. DHA is also needed for healthy vision and brain function. This balanced blend provides omega 3 fats in triglyceride form from cold-pressed, unrefined & filtered oils from wild sardines, anchovies and mackerel. Omega 6 provides the essential fatty acid, GLA which plays an important role in hormone balance by production of prostaglandins - chemical messengers with hormone-like activity. Complete Omegas also provides omega 7 from Sea Buckthorn oil which has been found to have an affinity for the skin and mucous membranes and may be particularly useful for post-menopausal women. Omega 9 (oleic acid) commonly known as a monounsaturated fat, is derived from Virgin Olive Oil, a principal ingredient of the Mediterranean Diet, which is associated with a range of heart healthy benefits.
