Liver is not only the richest source of ready vitamin A, but it is also a true nutrient bomb.
Steamed beets and pumpkins are also great sources of vitamin A (via carotenes), which also contain many other useful nutrients.
It is better to cover our vitamin A need from these, than to replace it.
Unfortunately many do not like or try to avoid liver, but in the meantime they do not prefer the consumption of carrots/pumpkins.
Our product is recommended to them, mainly if thy also take vitamin D3. We recommend the same amount, or maximum twice as much IU vitamin A replenishment, than the consumed IU of D3.
We recommend taking 1 to 10 drops a day, depending on the vitamin A content of our nutrition and our vitamin D3 intake.
