Most infant formulas have a very high vitamin A content. Most of the nutrition labels that I checked report having about 300 IU per 5 oz. Some brands are even higher.
Let’s do the basic math on this. A 10 lb infant can consume ~ 25 – 32 oz of formula per day.
Now, for an adult that is about 10X the RDA and is absolutely a toxic dose by established guidelines. But the current NIH listed RDAs for infants is:

Let’s convert this 400 mcg RAE back into IUs.
400 mcg RAE × 3.33 IU/mcg RAE = 1,332 IU
So, although a formula fed infant is getting ~ 30% more than their RDA, it’s still in the ballpark. That is until you factor in their actual body weight.
Then, it’s more than 10X the equivalent RDA amount for an adult. Although, body weight-based dosing is common in most pediatric medications it looks like that does not apply to a known to be toxic vitamin. Maybe the FDA and the NIH have just assumed that an infant somehow needs the equivalent of 10X the daily vA dose of an adult. Or maybe this was someone’s mistake in doing basic math? Either way, it shows a huge and complete disregard for safety. Especially so when you consider that an infant has a tiny and developing liver and therefore are less likely to quickly store that large dose.
It’s no wonder the USA (the leader in “medical science”) has the highest rate of infant mortality in the world. And one of the highest rates of autism too.
Anthony Mawson reported in one of his paper’s formula feedings is associated with a 13-fold increased risk of autism. A coincidence? I think not.
