Starbucks “Pink Drink” helps milk supply!?

I read this somewhere that it helps increase milk supply. I’ve been drinking it almost daily for the last two weeks and I think it really is helping! I had a problem producing sufficient milk now I’m having an overactive letdown. 😂😅 Anyone drink this?

Today they were having a buy one get one free so I got two Trenta Pink Drinks! 💁‍♀️
