What is the primary recommendation for pregnant or breastfeeding individuals regarding black radish intake?

Stick to amounts typically found in the diet

For vulnerable populations such as pregnant and breastfeeding individuals, the definitive stance regarding black radish consumption, particularly in concentrated supplement form, is one of extreme caution due to insufficient evidence. There is a recognized lack of reliable scientific data detailing the long-term safety profile of taking radish in doses that exceed what is normally encountered in standard food amounts during gestation or lactation. Therefore, the prevailing general advice is to limit intake strictly to amounts that would typically be present when consuming the vegetable as a regular dietary component, avoiding concentrated extracts until clearer safety information becomes available.
