Does gamma-linolenic acid really work for menstrual pain?

A chance encounter with purple seed oil from Rael containing gamma-linolenic acid

I'm taking supplements, but I haven't been taking them for long, so they really worsen my menstrual cramps.

I'm curious if it's effective~

Since there is a cost involved, I need to take two pills a day, but I am only taking one.

I wonder if I haven't felt the effects yet or if I need to take more...

I'm curious about the reviews from those who have experienced the effects.
