You can buy spearmint capsules at swansonvitamins.com. They are surprisingly cheap. Another possibility is DIM, which is also available at Swanson. I am not sure how DIM would interact with PM, however. If anyone reading this knows, please post!

Wow, they're much cheaper than what they sell for on Amazon!

If I decide to tryout spearmint capsules, I'll probably buy them from swason. Thank you for the link.

You are more than welcome!

All that said... I am in the process of trying to move to whole bulk leaves, which are cheaper yet! From amazon.

I believe you already have a capsule maker sabers? If not, you could always do it as a tea, or the way I'm doing it - putting it in food.
