In news that sounds too good to be true, moms are claiming that a Starbucks drink is helping to boost their milk supply. And we mean really boost; one woman says she’s pumping so much, she’s running out of the freezer space to store it.

LifeHacker reports that in the breastfeeding support group Milky Mamas—a private Facebook group—mom Laura Galvin wrote she leaked breast milk through her shirt for the first time after consuming the Starbucks Pink Drink.

Another mom, Stephanie Lester, told LifeHacker her breast milk flow became so strong after drinking the beverage that her daughter “got choked up” while nursing. "My milk was literally spraying for almost a minute and that has never happened before,” she adds.

What the heck is in the Pink Drink? It’s the Strawberry Acai Refreshers Beverage combined with coconut milk. Some moms think the electrolytes in coconut milk are responsible for the surge in their supply.

Still, nothing in the beverage stands out as a galactagogue, or a supplement that promotes lactation. And even if it did, galactagogues shouldn’t be your first treatment method if you’re having supply issues.

“Some moms will use supplements called galactagogues to help with problems with milk production. These can include herbs such as fenugreek, alfalfa leaf or goat’s rue,” certified lactation counselor Katie Lynch, RN, tells The Bump. “However, their effectiveness is debated. The best thing you can do if you are concerned about production is to attend a breastfeeding class during pregnancy or have a IBCLC-certified lactation consultant assist you with feedings to make sure you are on the right track.”

Other tips for boosting milk supply include:

Upping the frequency of feedings

Alternating breasts

Rectifying any latch issues

Using a pump
