Kirkland Signature Omega-3 Fish Oil Concentrate Review
Kirkland Signature Omega-3 Fish Oil Concentrate is a dietary supplement formulated to provide the necessary nutrients for the maintenance of a healthy brain and heart. The active compounds used to create the Costco manufactured supplement are believed to also bring additional benefits to the joints, immune system, skin and vision.
This formula is sold under the brand Kirkland Signature, the house brand of Costco Wholesale. The company is a retailer that commercializes a wide variety of products in numerous categories such as appliances, clothing, hardware and auto, electronics, furniture, health and beauty products, sport, fitness, travel accessories, etc.
The manufacturer of the formula is not disclosed for unknown reasons. A similar product sold under the same brand and containing 1200 mg fish-oil enteric coated flavored softgels is also offered by the same retailer.
Kirkland Signature Omega-3 Fish Oil Concentrate is formulated for the use of adults who want to improve certain aspects of their health (primarily memory, immunity, circulation, and bone density) or reduce symptoms of certain conditions (Alzheimer’s disease, heart disease, rheumatoid arthritis, etc.). The product does not contain artificial flavors or highly allergenic substances (yeast, starch or gluten).
Kirkland Signature Omega-3 Fish Oil Concentrate is marketed as a purified formula that lacks the toxic substances usually found in fish-oil based supplements: dioxins, furans, PCBs and mercury. The fish oil used as a raw material is derived from various fish species to maximize the concentration of essential fatty and increase potency.
Kirkland Signature Omega-3 Fish Oil Concentrate Ingredients
Kirkland Signature Omega-3 Fish Oil Concentrate contains the following ingredients: Natural Fish Oil Concentrate 1000 (EPA/DHA ), and other Omega 3, gelatin, glycerin, water, and Tocopherol.
Kirkland Signature Omega-3 Fish Oil Concentrate includes two main ingredients: EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid).
EPA is believed to be effective in maintaining the health of the heart and circulatory system. The substance is used in the treatment and prevention of coronary heart disease, to lower triglycerides, cholesterol and high blood pressure, slow bone loss in elderly people and reduce inflammation caused by rheumatoid arthritis. The number of the claimed benefits in the case of EPA is impressive, but no conclusive evidence can fully support the benefit claims.
DHA is essential for the healthy development, growth and functioning of the brain. Its importance in the growth and development of the central nervous system in unborn babies and infants is considered so high that today most of the baby formulas and foods have been enriched with DHA.
However, the compound is also important for maintaining normal cognitive function in adults. Decreased DHA levels in the case of adult have been associated with cognitive impairment in the elderly and high cholesterol. DHA containing supplements were shown to improve memory in patients suffering from Alzheimer’s disease and also in healthy people (positively impacting both short and long term memory).
Usually EPA and DHA based products have mild side effects like nausea or vomiting. A risk of bleeding may also occur in more severe cases (when excess amounts are consumed or the person suffers from certain conditions).
Kirkland Signature Omega-3 Fish Oil Concentrate is not recommended for pregnant/ nursing women or people who suffer from conditions related to blood clotting without the consent of an informed healthcare specialist.
The suggested use is 1 softgel two times daily after meals.

Kirkland Signature Omega-3 Fish Oil Concentrate offers a total of 300 mg of fatty acids per serving. There are several organizations that recommend daily allowances, but a dietary reference intake was not generally approved. The consulted sources suggest that in order to be effective, the total amount of EPA and DHA combined should not exceed 500 mg per day.
The company behind this formula claims that all raw materials are guaranteed to pass the CRN standards in terms of purity and safety. However, like most of the nutritional supplements, this is also is not approved by the FDA. And while the brand is highly appreciated among consumers, it is impossible to determine the extent of the formula’s benefits on the long term.
