Safety Risk Labels

This ingredient has the following documented risks:

Irritant: Although food-grade Saccharomyces cerevisiae is generally safe, rare allergic reactions to yeast have been reported (urticaria, rash, itching) after exposure or ingestion. For sensitive baby skin or infants with yeast allergy, exposure could cause skin redness or rash.
Immune system: Saccharomyces species are opportunistic pathogens in immunocompromised or medically vulnerable patients; case reports describe invasive infection (fungemia) from S. cerevisiae/S. boulardii in hospitalized or immunosuppressed infants and adults. This represents a risk to infants who are immunocompromised or have central lines.
