Omega 3 Fatty acids are one the most important Nutrients for human from birth to death. It's an essential fatty acids, approved by FDA for treatment of high triglycerides in two forms ( EPA & DHA ). omega 3 is anti-inflammatory in nature. It's responsible for brain, cardiovascular, Musculoskeletal, skin, eyes, depression, anxiety, cancer, boosts immunity, fights cancer, improves sleep, slows ageing process and many more Health benefits Most people don?t get enough omega-3 fatty acids, according to an analysis of dietary data about U.S. adults spanning 2003?2008.�There is no official daily value assigned to omega-3s, but the American Heart Association recommends two or more 3.5 ounce fish servings (oily, if possible) each week.� In general, most health organizations agree 250?500 milligrams of EPA and DHA combined each day is a reasonable amount to support healthy individuals. However, people with heart problems (or those with a high risk of heart disease), depression,�anxiety and cancer (and possibly more conditions) may benefit from higher doses�? up to 4,000 milligrams per day for some heart-related conditions. Plenty of research evidence are there to support its benefits and no research enough can be found which negates it's benefits. Undoubtedly, Glucosamine Sulphate is useless in many , some may have reported about it's pain relief quality that may be subjetive in nature. But enough of scientific evidence are there which states that Glucosamine Sulphate doesn't help with cartilage degeneration and pain relief. American Association of Orthopaedic Surgeons also states it's useless. Thanks !
