Papaya
Papaya is the fruit of Carica papaya. It supplies vitamin C and fiber, and the unripe fruit is a source of the enzyme papain.
What is known about supplement safety?
Allergic reactions and cross-reactions with latex and kiwi have been reported. Verbraucherzentrale advises people with papaya or cross-reacting allergies to avoid papaya supplements. 1
Can papaya trigger allergy?
Allergic reactions and cross-reactions with latex and kiwi have been reported. A history of these allergies matters when considering papaya preparations. 2
What does the pregnancy research actually show?
A rat study found no maternal or fetal toxicity with ripe papaya, while crude latex caused contractions in isolated rat uterine tissue. This distinction is important, but animal findings do not establish the safety of papaya supplements during human pregnancy. 3
