As you continue reading, you’ll learn everything there is to know about this nutrition-packed superfood including how it’s made, what it contains, health benefits, and the best brands available on the market right now.

How Nutritional Yeast is Made

A mixture of cane sugar and beet molasses are laid out in a small or large container covered by a breathable layer such as multi-layered cheesecloth or other cloth material to protect the mixture from insects.

Once the fermentation process has completed and the yeast is formed, it’s harvested, washed, pasteurized (hence why nutritional yeast is inactive and not used for baking), and finally dried before packaging.

Nutritional Yeast Benefits

1. Immunity Booster

Nutritional yeast is jam-packed with immune-boosting goodness. Virtually every nutrient it contains helps to boost and/or maintain immune system functions including B vitamins, zinc, iron, copper, and folic acid.

Aside from the vitamins and minerals this superfood offers, there are some unique immune-boosting properties exclusive to nutritional yeast including beta-1,3 glucan, trehalose, mannan and glutathione. Beta-1,3 glucan is a special fiber that’s been shown to boost immunity and lower cholesterol.

Studies have shown significant changes to immune system health when beta-1,3 glucan is added to the diet including reduced sick days from work. It also decreases the incidence and severity of health issues such as the common cold and flu, along with “traveler’s diarrhea” which affects people traveling to locations with different bugs and creepy-crawlies roaming around in the air, food, and water that the immune system isn’t accustomed to.

The other compounds mentioned above including glutathione, are essential to maintaining immune system health and reducing oxidative stress throughout the body. These facts make nutritional yeast among the most potent immune boosting foods available in natural form.

2. Improves Digestive Health
