Cod liver oil was used in Europe as a natural source of vitamins for centuries, it provides vitamins A and D which can be solved in fat but not in water. A regular diet doesn’t provide enough of these vitamins, beneficial for bones and teeth. Cod liver oil is also a rich source of EPA (eicosapentaenoic acid) and DHA (docasahexaenoic acid). These are fatty acids necessary for the proper function of the nervous system and brain. They can be produced in body from omega-3 linolenic acid, but in some circumstances, e.g. deficiencies of nutrients or diabetes they must be taken as a supplement. Deficiency of the omega-3 acids produces also an imbalance in the omega-3 to omega-6 fatty acids ratio and contributes to blood vessel and heart disease.
Paired with butter oil
Cod liver oil gives best results when taken with high-vitamin butter oil. Butter oil is a rich source of vitamin K2, also named Activator X, which works together with vitamins A and D. Tim Ferriss observed this effect when he was on trip in Nicaragua, eating all the time grass-fed beef, a potent source of vitamin K.
Boosting testosterone level
Tim Ferriss experimented with increasing his sperm count and testosterone level, using the Blue Ice Cod Liver Oil. He developed two programs for rising the testosterone level; one long term and one for a short boost before sex. Green Pasture Blue Ice Royal Butter Oil/Fermented Cod Liver Oil Blend is the core supplement of the long term program, paired with brazil nuts and almonds (one serving should contain 4 brazil nuts and 4 almonds).
Which cod liver oil is the best?
What should you expect when buying cod liver oil? The best cod liver oil should be high-vitamin and fermented, combined with high-vitamin butter oil (a rich source of natural vitamins) – e.g. Green Pasture Blue Ice Royal Butter Oil/Fermented Cod Liver Oil Blend. It is more beneficial for your health than processed cod liver oil with synthetic vitamins added.
Blue Ice is produced by a small manufacturer and can be sold out or perhaps you can find it too expensive. A more available alternative suggested by Tim Ferriss was Carlson Cod Liver Oil paired with high quality butter (Tim mentioned Kerrygold Irish Butter) taken simultaneously.
The dosage of the Green Pasture Blue Ice Royal Butter Oil/Fermented Cod Liver Oil Blend is 2 capsules a day.
