Ben Greenfield explores whether omega-3s like DHA and EPA support brain health, memory, and mood. He compares how your lungs absorb these nutrients versus your gut, challenging common assumptions about where the real benefits come from.
The Omega 3s, particularly those you'd find in, say, fish oil, play a critical role in brain structure and function. So high levels of DHA and EPA have been found over and over again to support memory, mood and cognitive function at about 1 to 1.5 grams daily. It has been studied and associated with improved memory, attention and cognitive performance, particularly in older people. At about 100 to 300 milligrams per day, it's also great to take at night if you're stressed. Phosphatidylserine is great for controlling cortisol. Your lungs can actually, this is surprising. They can absorb far larger molecules than your gut can, 260 times larger, to be exact. You know, this is why when people inhale cocaine or cannabis or nicotine or anesthetics like laughing gas, right. That enters the body within seconds and are effective at much lower concentrations than would be needed if they were consumed orally.
