Risk profile
Safety & processing
Garlic is a raw, whole-food bulb straight from the ground. Nutritional Yeast is a processed product, grown on molasses, deactivated, and often fortified with synthetic B-vitamins, though it remains free of artificial chemicals and preservatives.
Garlic
Botulism from improper oil storage
highStoring raw Garlic in oil at room temperature creates an anaerobic environment where botulism spores can thrive.
Medication interaction
mediumGarlic acts as a natural blood thinner, which can compound the effects of anticoagulant medications.
Nutritional Yeast
Yeast sensitivity or histamine reaction
mediumThough deactivated, Nutritional Yeast can still trigger histamine responses or bloating in those with yeast sensitivities.
Synthetic fortification concerns
lowSome consumers prefer to avoid the synthetic B-vitamins used to fortify most Nutritional Yeast brands.
