Why cant I pretend down after taking an iron pill?
The website says that you shouldn't fiction down after taking any tablets or capsules so to brand name sure it gets down to the stomach instead. I can individual imagine that it enhance the passage of the pill down the throat, instead of sticking to the side of the throat.
The most impressive thing is of late not to lean forward or lie facade down because it can get into your lung.
