Any concern about vitamin toxicity with seafood?

Answered on August 19, 2014

I've been enjoying a lot of seafood/fish lately (clams, mussels, salmon, sardines, herring come to mind.) Aside from the concerns about mercury and BPA in the cans, and the junk oils that come in some canned seafood, should I be concerned about overdosing on Vitamin A (I know there's that risk with fish oil), or on Vitamin D (I imagine it's really hard to overdose on Vitamin D from food) or on anything else from seafood?

I always seem to crave more fish in the summer and more meat in the winter, myself.

I just picked up a 21 ounce sockeye salmon fillet for my dinner tonight.

Maybe 8 to 12 ounces a day. Feeling a draw right now to more fish and less meat. I find my tastes change every few months although fortunately they stay pretty much in the paleo framework.

Most vitamins are hard to overdose on without supplementing heavily. Just eat real foods and you will be fine. I assume you are not eating a couple pounds of fish every day.

What about the vitamin A? Most has very little vitamin A. I'd be more concerned about all the eggs that people seem to devour around here.

All you'll ever need to know:

!!!Spoiler Alert!!!

In it's natural setting, with natural co-factors it is extremely unlikely that even several pounds of seafood per week are going to give you anywhere near a Vitamin A or D toxicity. The problem arises when we supplement one without getting the other. Vitamin A toxicity is a Vitamin D deficiency. So if we just stick to the foods that we evolved eating we don't have to worry, nature took care of these checks-and-balances a long time ago.

You have no worries about overdosing on Vit D from food. Most studies suggest the health risks of not eating seafood far outweigh any risk of eating seafood. Sure, try to go for fresh whenever possible, and don't eat the canned with added oils, but as a whole there isn't a lot to worry about.

It's extremely hard to overdose on Vit A with cod liver oil or fish oil. There's something about synthetic vitamins that just doesn't jive with our bodies. Moderate chronic doses of Vit A for extended periods of time are very safe. High doses of Vit A for short period of time are what you need to worry about.

Unless you're guzzling excessive amounts of the CLO/FO on top of eating liver a few times a week, I wouldn't really worry about it.
