How to Buy Cod Liver Oil

Cod liver oil has a variety of health benefits. According to "Foundations of Nursing," when taken daily, cod liver oil can reduce triglycerides by 20 to 50 percent in people with elevated triglycerides and reduce blood pressure in those with mild hypertension. Though cod liver oil is generally safe for most people, according to "Contemporary Nutrition," it is essential that you consult your physician prior to adding cod liver oil, or any other supplement, to your health regimen.

Step 1

Consult your physician to discuss your desire to take cod liver oil. Your physician will evaluate your medical history to determine if cod liver oil is safe for you and the appropriate dosage. Taking too much cod liver oil can cause vitamin A toxicity, vitamin D toxicity and nausea.

Step 2

Browse a drugstore's supplement aisle for cod liver oil, which is commonly available in capsule and liquid form.

Step 3

Purchase cod liver oil in capsules convenient to take in the dosage recommended by your physician and in the form you feel best fits your needs. For example, if you have difficulty swallowing capsules, buying cod liver oil in bulk as a free liquid would be a better fit.
