For centuries cod liver oil was taken in Europe, it is a valuable source of omega-3 fatty acids and vitamins. Cod liver oil provides vitamin A and vitamin D, both being beneficial for bones and teeth. The vitamins can be solved in fat but cannot in water. A regular modern diet doesn’t provide enough of these two vitamins. Vitamin D can be produced by body, provided enough exposure to sunshine.
Nowadays we spend too much daytime in offices to rely on this natural process. Cod liver oil is a very rich source of fatty acids DHA (short for docasahexaenoic acid) and EPA (short for eicosapentaenoic acid). They are necessary for the normal function of the brain and of the nervous system in general. Our body can produce EPA and DHA from omega-3 linolenic acid, however under some conditions, e.g. diabetes or deficiencies of nutrients they must be delivered in form of a supplement. Deficiency of these omega-3 acids can cause also an imbalance between the omega-6 and omega-3 fatty acids and contribute to diseases of blood vessels and of the heart.
Combined with high-vitamin butter oil
The health benefits are most appreciable when cod liver oil is taken with high-vitamin butter oil. High-vitamin butter oil is a perfect source of vitamin K2, called also Activator X, working together with the vitamins A and D. Tim Ferriss noticed this beneficiary effect when on trip to Nicaragua, eating plenty of grass-fed beef, a valuable source of vitamin K.
Rising testosterone level
Tim Ferriss experimented with cod liver oil in order to boost his testosterone level, and to increase sperm count, using the Green Pastures Cod Liver Oil capsules. Tim created two programs for boosting his testosterone level; one for long-term effects and one for a short testosterone boost before sex. The Green Pasture Blue Ice Royal Butter Oil / Fermented Cod Liver Oil Blend is the essential part of the long-term program, combined with almonds and brazil nuts (one serving containing 4 almonds and 4 brazil nuts).
Best cod liver oil – what to look for?
What should you look for when you buy cod liver oil? Cod liver oil should contain plenty of vitamins, is fermented, and paired with high-vitamin butter oil (a valuable natural source of vitamins) – e.g. Green Pasture Blue Ice Royal Butter Oil / Fermented Cod Liver Oil Blend. Fermented cod liver oil is better for your body than artificially processed oil with added synthetic vitamins.
Carlson Cod Liver Oil
Blue Ice Cod Liver Oil is produced by a small manufacturer, Green Pastures, and you can find it to be expensive or it can be sold out. A cheaper alternative to Green Pastures recommended by Tim was Carlson Cod Liver Oil paired with high-vitamin quality butter (Tim Ferriss suggested Kerrygold Irish Butter). Butter and the cod liver oil should be taken simultaneously.
Dosage
Green Pasture Blue Ice Royal Butter Oil/Fermented Cod Liver Oil Blend works optimal if you take 2 capsules a day.
