Ingredient 4 of 5
Pumpkin seed in Prostacor
Pumpkin seed is fourth of the five ingredients, which puts it near the light end of the blend.
On the label
The fourth line of the blend
"Pumpkin Seed"
The label line reads "Pumpkin Seed". It stands fourth of the 5 in the 351 mg blend, ahead of lycopene only.
The label does not say whether the capsule holds ground seed or a seed extract. The largest study on the subject found the two behaved differently.
Research
What the published source says
Quoted from Urologia Internationalis.
After 12 months, the response rate (intention-to-treat/last-observation-carried-forward approach) did not differ between pumpkin seed extract and placebo.
In order to fully justify a recommendation for the use of pumpkin seed to treat moderate LUTS, these findings need to be substantiated in a confirmatory study or systematic review.
In the capsule
What that means for a capsule
The GRANU study followed 1,431 men for a year. Men given 5 grams of whole seed twice a day did somewhat better than placebo. Men given 500 mg extract capsules did not.
Five grams is more than 14 times the whole 351 mg blend in a Prostacor capsule. The capsule cannot match the seed dose in that study.
