Sure! As long as that's not polar bear liver [1]; you be mindful of other unlikely dietary sources of unusually high retinol content like sweet potatoes, pumpkins or cod liver oil [2]; and keep up with regular check-ups; you'll surely avoid hypervitaminosis A.
Case in point to show how I use supplements: My kids won´t take liver, no matter how hard I try to "hide" it. So, I give them 1/4 teaspoon per week of cod liver oil (green pastures, fermented).
Again, it´s not the supplements; it´s the product.
