Prickly pear supplements come from the fruit or pads (nopal) of the Opuntia cactus. Fruit extract contains betalains and vitamin C, while pads offer soluble fiber. The water-soluble compounds in the extract may be absorbed easily, supporting hydration and antioxidant defenses.
People take prickly pear to promote skin elasticity and moisture, aid digestion with its fiber, and support antioxidant defenses. Others use it to help maintain blood sugar and cholesterol levels already in the normal range, though the evidence is mixed. Capsules and powders are common forms.
For best absorption, take with a meal. Dosage varies by form. Fruit extract capsules often range from 500 to 1000 mg daily, while nopal powder may be taken in gram amounts. Start with a lower dose to assess tolerance.
Caution: Prickly pear may lower blood sugar and blood pressure. If you have diabetes or take medications for blood pressure, monitor levels closely. Stop use at least two weeks before scheduled surgery. Safety during pregnancy and breastfeeding is unknown.
