The Core Components: Omega-3, Vitamins A, and Vitamin D

Many Seven Seas products, particularly their cod liver oil line, contain Omega-3 fatty acids, Vitamin A, and Vitamin D. As the body cannot produce Omega-3s, dietary intake or supplementation is necessary.

How Omega-3s Support Your Health

Omega-3 fatty acids, like EPA and DHA, offer various health benefits. They support normal heart function, potentially aiding in maintaining healthy blood pressure and triglyceride levels. DHA is crucial for normal brain function and vision. Omega-3s also possess anti-inflammatory properties that may help manage chronic inflammation.

The Role of Vitamins A and D

Seven Seas cod liver oil naturally provides Vitamins A and D. These vitamins are vital for immune system function. Vitamin D is also essential for bone and muscle health by regulating calcium absorption. Vitamin A further contributes to healthy skin and vision.

Simply Timeless Cod Liver Oil: The traditional product with Omega-3s, Vitamin A, and Vitamin D.
