Brand Recommendations – Updated 2014
The high-vitamin fermented cod liver oil is sold as a food so does not contain vitamin levels on the label. However, after numerous tests, the approximate values of A and D have been ascertained at 1900 IU vitamin A per mL and 390 IU vitamin D per mL. Thus 1 teaspoon of high-vitamin fermented cod liver oil contains 9500 IU vitamin A and 1950 IU vitamin D, a ratio of about
5:1.
Based on these values, the dosage for the high-vitamin fermented cod liver oil is provided as follows:
Children age 3 months to 12 years: 1/2 teaspoon or 2.5 mL, providing 4650 IU vitamin A and 975 IU vitamin D.
Children over 12 years and adults: 1 teaspoon or 10 capsules, providing 9500 IU vitamin A and 1950 IU vitamin D.
Pregnant and nursing women: 2 teaspoons or 20 capsules, providing 19,000 IU vitamin A and 3900 IU vitamin D.
Please note that the fermented cod liver oil contains many co-factors that may enhance the body’s uptake and usage of vitamins A and D; in fact, many have reported results equivalent to those obtained from high-vitamin cod liver oil with half the recommended dose, that is ¼ teaspoon or 1.25 mL for children age 3 months to 12 years; ½ teaspoon or 5 capsules for children over 12 years and adults; and 1 teaspoon or 10 capsules for pregnant and nursing women.
