The relationship between cod liver oil and constipation is one of natural treatment and nutrition. In other words, cod liver oil has been used to relieve constipation naturally for many years. Other fish oils provide the same benefit, without the risks that may be associated with excessive consumption of cod liver oil. Both oils provide essential omega-3 fatty acids, necessary for optimal function of the brain, heart, joints, and digestive system.
Both my parents and grandparents took regular doses of cod liver oil and constipation was not a problem for them. After complaining of a “tummy ache”, my mother gave me a spoonful of that foul-tasting, smelly stuff. After that, I kept my tummy aches to myself. Sure, she relieved the constipation, but “Yuk!” I could taste it for hours, every time I burped!
Today, the best fish oil supplements are molecularly distilled to eliminate odor. In capsule form, they are tasteless. Storing the capsules in the freezer and/or taking them with food can prevent both burping and aftertaste, while relieving occasional constipation.
Most people experience constipation occasionally. Too little fiber in the diet is a common cause, as is too little water. But, many other factors can contribute to occasional constipation. Prescription medications, iron-containing dietary supplements, a sedentary lifestyle, travel or other changes in routine, and stress are some of the many things that can lead to constipation.
Excessive use of stimulant laxatives can cause eventual dysfunction of the digestive muscles, leading to chronic constipation. Most people find that even occasional use of stimulant laxatives can cause cramping and discomfort. Fish oils improve digestive function, can be taken regularly, and are “milder” than most over-the-counter laxatives, such as Ex-Lax. Many people associate cod liver oil and the prevention of constipation.
Just remember to choose wisely. All supplements are not created equal. Cod liver oils contain vitamin A. Pregnant women should avoid supplements containing vitamin A, as it has been associated with a significant increase in birth defects. Too much vitamin A, even in healthy adults, can be toxic. In general, it is safest to get your daily vitamin A requirement from food or from beta-carotene, which is converted to vitamin A by the body as needed and is therefore non-toxic.
Other concerns about cod liver oil consumption are related to mercury contamination and contamination by other industrial pollutants. Mercury is stored in the liver of fish. Therefore, there is a greater possibility of mercury contamination in oils that come from fish livers. The source of most cod liver oils is Atlantic cod, which has been overfished and swims in some of the world’s most polluted waters.
Fish oils derived from the “meat” of fish are generally safer alternatives. But, you still need to choose carefully. Some oils are not molecularly distilled and contain mercury and other contaminants. And, if you’re concerned about environmental issues, some fish are overfished and their populations are not considered sustainable. Manufacturers are required to list the “fish of origin” (cod, shark, salmon, etc.), the distillation process used, and the ocean the fish is sourced from, but most do not.
