You should always take the manufacturer’s recommended dosage for fish oil or follow your doctor’s advice. There is no minimum daily allowance or RDA, although there is an AI for the nutrients found in the oils.
An AI is an acceptable intake. The nutrients in question here are omega-3 fatty acids. Fats are not assigned RDAs or recommended daily allowances.
An AI and an acceptable percentage of total caloric-intake are established by the USDA and other health organizations. These are sometimes referred to as distribution ranges. They are designed to help people choose a variety of foods, rather than getting too many of their calories from a Ibutamoren MK-677 single source, which has never been considered healthy.
The AI for omega-3 fatty acids is currently 1.6 grams/day for men and 1.1 grams/day for women. This may change soon, because they are scheduled to be reevaluated in 2010.
The USDA suggests that omega-3s can account for.6% to 1.2% of total caloric intake. Many doctors and researchers think that is actually inadequate.
A doctor’s recommended dosage for fish oil may be as high as 3000mg per day for men and women. In some cases, it is even higher. Recommending 5000mg is not unheard of.
This should not be construed as a recommendation for your personal intake. It is simply an example of some of the dosages that have been suggested.
It is difficult to understand the USDA recommendation for omega-3s. The organization suggests that in a healthy diet 20-35% of total calories can come from fats.
