The History of Fish Oil (part 2 of 2)
So while it's true that 1 tablespoon of cod liver oil supplies 2.5 grams of long-chain omega-3 fatty acids, it is also true that it supplies contaminants and a high dose of vitamin A, which is stored in the body's fat tissues and can cause toxic effects like hair loss if taken in high enough doses.
The final breakthrough in fish oils happened when Ultra Refined EPA and DHA concentrate Omega-3 product was developed. EPA and DHA are almost found exclusively in sea foods. The process required advanced chemical engineering that starts with the removal of most of the saturated fat by fractional distillation and the removal of virtually all the PCBs (measured in parts per billion) by more sophisticated molecular distillation. In the process called polishing, impurities are removed through hot water. The fish oil are also added with anti-oxidants for longer life and added nutrients.
With these innovations, a new type of fish oil was developed. The end-product ensures you to have a concentrated amount of long-chain Omega-3 fatty acids without unwanted substances like chemical contaminants or harmful fatty acids that can harm your well-being.
It is only with the use of pharmaceutical-grade fish oil that you can get high enough levels of long-chain Omega-3 fats for your brain and body. The effect of the high-grade fish oil usually occurs after taking it everyday in 30 days.
