I've been recommending blackstrap molasses for 35 years.
I learned as a kid that it was given to horses to help with their immune systems and the factoid stuck with me.
Once I figured out that it was probably because of the concentrated broad-spectrum minerals, I started taking it myself circa 1990.
For those who might be interested, the broad-spectrum mineral content is likely 'cause of sugar cane's deep-reaching roots. Obviously the minerals "settle" once the juice is squeezed, hence the transition from clear at the top to "black" at the bottom. The clear stuff is used to make sucrose, the darker for molasses and the darkest, bottom-of-the-barrel stuff is blackstrap.
