Sorghum supplies numerous essential nutrients in rich content (20% or more of the Daily Value, DV), including protein, fiber, the B vitamins niacin, thiamin and vitamin B6; and several dietary minerals, including iron (26% DV) and manganese (76% DV).
Sorghum nutrient contents generally are similar to those of raw oats.
Sorghum contains no gluten, making it useful for gluten-free diets.*

While sorghum has long been thought safe for celiacs, no clinical testing had been done until researchers in Italy made a study. First, they conducted laboratory tests.**

Consuming sorghum benefits your health, thanks to its magnesium and copper content. Magnesium contributes to healthy bone tissue and regulates your body’s calcium levels, while copper boosts your immune system and promotes red blood development. Both minerals also play a role in your metabolism and help your cells produce useable energy.
