Due to their natural anti-inflammatory properties, including the ability to reduce prostaglandin production, omega-3s reduce the need for anti-inflammatory medications and can be used to treat a variety of symptoms naturally, from risk factors for coronary heart disease to depression or arthritis.


Supplementing with omega-3-rich cod liver oil is one way to reduce inflammation and re-increase your fatty acid ratio for better health.

Vitamin A is an important antioxidant that reduces oxidative stress (also called free radical damage) and therefore inflammation levels.

it is linked to the prevention of eye-related disorders, supports brain health, helps fight cancer, and is important for hormone production.

While most people who eat a fairly balanced diet get enough vitamin A, the daily deficiency is a risk for some people who eat highly processed foods or who don’t consume enough calories in general.

Recently, vitamin A supplementation has been debated as high levels are thought to be really harmful and potentially toxic.
