Good to eat fat in conjunction with the vitamin

Since vitamin A is a fat-soluble vitamin and it is excreted slowly in the body, it is good to get enough fat together with the vitamin. Fat intake can make it easier for the body to pick up vitamin A that you get through food and possible supplements. But keep in mind that it should of course be good fat and of course not exaggerate just to get a better effect with vitamin A.

Stored in the liver

Vitamins that are excreted in fat are stored in our liver and the body’s adipose tissues if you get more than you need. This means that you do not have to get vitamin A every day. It is enough that you get enough in you once or twice a week. The stock that is built up can last for several weeks. Sometimes for several months.

Better in food than in pills

As always, we believe that your need for vitamins and vitamin A should be covered by the food you get in you rather than taking supplements. This is because, as always, we advocate natural diets and it can be easy to overdose with pills. Also, the natural fat content of the food you eat can help your body absorb the vitamin.
