This article is about diet. Where is the source that says that women have stored reserves of omega 3 that are depleted with measurable impacts on later born children?

I'm sorry, do I need to post a biology class in here too? I can post the study about how women with bigger butts have smarter children due to higher Omega-3 availability, and the study detailing the depletion during pregnancy, and the study I already posted on Omega 3 in the diet.

Or, the idea that building a human depletes resources could be relatively uncontroversial, because duh.

Please post those studies I want to seem something.

Omega-3 stays in your body for only about 6 months and must be continuously replenished. This can be an issue over the course of a single pregnancy. But it's not something that gets progressively depleted over multiple pregnancies.

Aren't prenatal vitamins (which include omega-3) essentially prescribed by default nowadays?

Yes, which is why OP's study based on data from the 1950s is already problematic.

However, a fixed cocktail of supplements isn't ideal. Some people actually get their bloodwork done and concentrate on what they really need.

This study doesn’t at all say what you originally claimed about moms “running out of resources as time goes on” when it comes to birth order and IQs. Either you missed the point or you honest to god don’t care about spreading disgusting misinformation.

Actually, it does, but only if you have reasonable reading comprehension.

How is what I'm saying "disgusting misinformation"? I'm very interested in what precisely you're angry at.
