The mechanisms of action that I'm referring to don't depend upon physically transporting molecules into the brain. Also, as it turns out, even inflammation in your gut or elsewhere changes the signals that the nerves send to the brain. And levels of neurotransmitters in the brain are absolutely impacted by what's going on in the rest of the body...regardless of the BBB. What specific point are you trying to make about the Blood-Brain Barrier? And stomach acid? Sorry but neither of those things somehow render the foods and chemicals we ingest meaningless! Your HCL won't somehow break down Magnesium! Even Vitamins will mostly make it through intact. I'm not a scientist but I don't get my information from Men's Health magazine either...I research reputable scientific studies and make reasonable connections.
