Breast milk isn’t just for babies anymore, and yes, adults are drinking it. From bodybuilders calling it a “super protein” to DIY skincare fans adding it to their baths, this trend is real and rising.
But is it bold innovation or just biological overreach? Let’s dive into five reasons behind the craze, and what science actually has to say.
Curiosity and Social Media Challenges

WANT TO SAVE THIS RECIPE?
Driven by internet dares and viral challenges on TikTok or YouTube, some adults sample breast milk just for the shock factor or curiosity. These experiments rarely turn into habits, but health experts warn that dabbling in bodily fluids without proper screening can carry serious health risks.
Bath Time Goes Biological
Some adults are lathering up with breast milk, mixing it into soaps or soaking in milk filled tubs, hoping its natural fats and antibodies calm irritated skin, eczema, or rashes. While the idea sounds nourishing, experts caution that without proper storage or sterilization, contamination risks outweigh the skincare benefits.
Coffee Replacements or Creamer
A small number of people, including some celebrities, have tried breast milk in coffee or lattes as a homemade creamer alternative. While it’s made waves online, nutritionists caution that the health claims are anecdotal, and it remains a fringe choice more than a trend.

Athletes Mixing it into Shakes
Some adults mix breast milk into smoothies or protein shakes, often combined with fruit or protein powder. The logic seems to be nutritional; breast milk contains antibodies, fats, and sugar. Still, doctors point out that adult digestive systems handle those nutrients differently and adults don’t need them in that form.

Bodybuilders Treat it as a Natural Supplement
Many athletes and bodybuilders purchase human breast milk, sometimes paying up to $2 an ounce, believing it boosts muscle growth, recovery, or immunity. Sellers report earning thousands of dollars from this demand. However, researchers stress that no clinical studies support any adult health or fitness benefits.

Even though adults are experimenting, whether they’re following nutrition buzz or personal curiosity, scientific experts emphasize there’s no proven benefit. Breast milk remains a substance best suited for infants. Seek trusted, evidence based nutrition, and let caution guide you when exploring the unexpected.
