HIBA, & any one else reading this, it'll depend on how much vitamin A & D are in your capsules. Many labs make cod liver oil capsules in varying strengths. It's perfectly safe to get 20,000 IU of vitamin D & 2,000 D daily. The RDA of vitamin D especially is now thought to be far too low. Vitamin D has been found to have additional benefits & like one poster mentioned (I forget who) D works more as a hormone than vitamin. Just make sure you take enough vitamin E when you take any higher amounts of fat in your diet - good or bad fats. And as noa (I think) mentioned, sufficient calcium & magnesium balance out your intake of D nicely.
Bone breakage from too much vitamin A is possible but the levels mentioned are 25,000 IU - 50,000 IU per day or more for long periods. I also wonder if too much A coupled with not enough D has adversely affected bone density. Many supplements have a fair amount of A but little D & there are supplements available of high amounts of vitamin A with no D at all. I wish the level of vitamin D was also checked in these men's blood. There may be other factors that have put those who take excessive vitamin A at risk. I know my intake of A & D is quite high (but not excessive) & my bone density is excellent.
