Women who have been through the menopause, and older men, should avoid having more than 1.5mg of vitamin A per week from food and supplements. This is because older people are at a higher risk of bone fracture. This means not eating liver and liver products more than once a week, or having smaller portions. It also means not taking any supplements containing vitamin A, including fish liver oil, if they do eat liver once a week.
Pregnant women should avoid liver and liver products and vitamin A.
