The Turkey
A three-ounce serving of ground turkey contains 173 calories and 1.14 mcg of vitamin B12, which is nearly 49 percent of the daily value. If you’re searching for a low-saturated fat option that can still boost your vitamin B12 levels, ground turkey is an excellent substitute for ground beef. Additionally, turkey contains tryptophan, an essential amino acid required by the body to produce serotonin.
