1. What is bromelain?

Bromelain is a mixture of proteolytic (protein-digesting) enzymes extracted from the stem of the pineapple plant. It has long been used as a digestive aid and as a natural anti-inflammatory remedy. In fertility medicine, bromelain is mainly used in the treatment of endometriosis, where its anti-inflammatory effects can help reduce pain and pelvic inflammation.

Reference ranges and recommended intakes vary from country to country — always interpret guidance against the recommendations of your own healthcare authority.

2. Function and how it works

Bromelain works through several mechanisms:

1. Anti-inflammatory effects. Bromelain reduces production of pro-inflammatory prostaglandins and cytokines, which contribute to endometriosis pain.
2. Reduces fibrin deposition. Bromelain may reduce the abnormal scar-like adhesions that develop in advanced endometriosis.
3. Improves circulation. Bromelain has mild blood-thinning effects that improve circulation to the pelvic organs.
4. Synergy with turmeric. Bromelain enhances the absorption and anti-inflammatory effects of turmeric (curcumin).

3. Fertility benefits

Important: Bromelain decreases prostaglandin E2, which is necessary for ovulation and implantation. For this reason, I do not generally recommend bromelain for women trying to conceive unless they have endometriosis, where the inflammatory benefit outweighs the prostaglandin reduction.

For women with diagnosed endometriosis, bromelain — particularly when combined with turmeric — can reduce pain and inflammation while preparing the body for natural conception or IVF.

4. Recommended daily dose

I recommend a daily dose of 500–1,000 mg of bromelain (typically 2,000–2,400 GDU/g activity), taken away from meals on an empty stomach for systemic anti-inflammatory effect. Take with meals if using as a digestive aid.

Use only for endometriosis or other inflammatory fertility conditions, not for routine fertility support.

5. Sources

Bromelain is concentrated in the stem of the pineapple, with small amounts in the fruit. The enzyme is destroyed by cooking, so canned or cooked pineapple has little bromelain activity. Supplemental bromelain is the practical way to achieve clinically useful doses.

6. Cautions and contraindications

1. Avoid for routine fertility support — bromelain reduces prostaglandin E2 needed for ovulation and implantation.
2. Discontinue bromelain once pregnancy is confirmed.
3. Do NOT take bromelain if you are taking blood-thinning medication (warfarin, aspirin) without medical supervision.
4. Stop bromelain at least two weeks before any planned surgery.
5. Some people are allergic to pineapple and bromelain — discontinue if rash, swelling or breathing difficulties occur.
6. Always consult with a fertility specialist or your doctor before starting any new supplement regime.
