Nutritional yeasts like this Super Rich Yeast Plus from Twinlab can be a great addition to your health shakes by adding vitamins, minerals and other nutrients that most protein powders lack. Super Rich Yeast Plus is also used by some people for its highly bioavailable chromium content. Chromium is an essential mineral with a critical role to play in the utilization of insulin, and chromium makes a positive impact on many types of blood sugar disorders. But chromium is one of the hardest minerals to obtain from diet. So Super Rich Yeast Plus makes a great whole-food source of chromium that's easy to use in shakes or over cereals or yogurt.
