Most protein bars are safe during pregnancy. Check labels for caffeine (some contain green tea extract or coffee), herbal supplements (avoid ginseng, guarana), and artificial sweeteners. Bars with whey, pea, or egg protein are fine.
A "Generally Safe" rating means this food doesn’t carry a pregnancy-specific safety concern beyond ordinary food-handling practices — the same basic hygiene and storage habits that apply to anyone. These ratings are based on general guidance from the FDA, ACOG, CDC, and USDA rather than a claim that every possible preparation of the food is automatically fine; how something is prepared, stored, and served still matters. If a "generally safe" food has any handling caveats (like a preparation method or freshness window), they’re noted separately in the sections below rather than changing the overall rating.
