You have correctly ascertained that it would be ridiculous to drink Propel to nourish your brain. Hopefully, no one is drinking 4-6 Propel per day but, if they are, and also are taking choline supplements or eating loads of tofu, they may indeed start smelling like a fish. Someone should also point out that while choline may nourish the brain, phosphatidylserine and/or acetyl l-carnitine would be much more beneficial for fueling the brain. Why don’t they add that? They are more expensive than choline. Also, they could remove the artificial sweeteners and use stevia, which would be healthier but also cost more. Let’s face it, Propel and Gatorade are nothing more than flavored water with great marketing to a gullible market!
