the way Parasym Plus works is if you take 2-3 capsules at once (preferably on an empty stomach — I would try first thing in the morning), the body puts it together quickly and it stimulates the (postganglionic) vagus nerve, stimulating normal movement of stool and digestion (in addition to calming the heart, encouraging proper breathing — all functions of the vagus nerve. It also crosses the blood-brain barrier and boosts brain levels of acetylcholine (needed for cognition and memories). So, yea, I think you’re right — it’s likely not enough to do much! 😉
