For me personally, from childhood to adolescence I don't eat beef. (For religious reasons) And when I tried to eat beef It caused side effects like sores on the lips, itching, and I think it was a food allergy. (similar to an allergy to certain types of seafood in some people)
So I don't mainly eat beef. And I mainly eat pork. with supplements involving pork entrails and seafood
(I named it Carnivore 20g because I need a balanced diet. And there are very few cases to read. Since I don't eat beef) *Of course it's safe. Because I have a health check every 3 months, I am confident.
