Nowadays, it has become very common to go to the pharmacy and buy vitamins and nutritional supplements. Some people choose the things they want without even asking a doctor. Among these, cod liver oil capsules are a popular one among many. So, what exactly is cod liver oil? Is it good for the body to use it? Let's talk about this today.
What is Cod Liver Oil?
Simply put, cod liver oil is an oil extracted from the liver of a fish called 'cod'. It is very nutritious. The main reason for this is the valuable components contained in this oil.
- Omega-3 fatty acids: These are a type of fat that is very beneficial for our body. They are especially helpful for brain function, heart health, and joint health.
- Vitamin A: Vitamin A is essential for maintaining good eyesight, healthy skin, and a strong immune system.
