Am I calculating this incorrectly?

>read rat studies on significant cognitive benefit of DHA supplementation
>the rats weigh 200-240g, and the supplementation in their rat chow is always "1.25% DHA" and they are always allowed to eat ad libitum(whenever and however much they want)
>rats apparently consume ~20-25g of food each day so their consuming ~300mg of DHA per day during these studies, but they only weigh up to ~250g, so their mg/kg/day dose is ~1,200mg/kg/day
>converting rat dose to HED(human equivalent dose) is rat dose multiplied by 0.162
>the HED is ~200mg/kg/day, or 10,000mg in a 50kg person, for all of these beneficial cognitive effects
Even with supplements, you will never have access to 10,000mg of DHA per day. You could barely touch 5,000g even with the most concentrated supplements and you'd spend ~$4-5 per day to achieve this. This must be incorrect. You could not reach this with salmon and sardines either. You'd have to consume 1.5lbs of salmon every day to potentially touch 10,000mg of DHA.
