Erewhon and Function launch ‘World’s Healthiest Smoothie’ with 160 lab tests to back it up

Move over, Hailey Bieber — there’s a new status symbol hitting the shelves at Erewhon — and this one claims to have the data to back it up.

The cult-favorite grocer is teaming up with high-tech wellness startup Function to launch “The World’s Healthiest Smoothie?” a yearlong collab that aims to rethink what “healthy” actually means.

Starting today, the drink will be available for $16 in glass bottles at all SoCal Erewhon locations in Greater Los Angeles through February 2027. The smoothie isn’t just another superfood blend, its creators told The California Post.

It’s a “biohacker in a bottle” designed by Function co-founder and longevity expert Dr. Mark Hyman to target real nutritional gaps observed across Function’s massive database of members. According to the company, more than 65% of members fall outside the optimal range for fasting insulin, and 54% show elevated Apolipoprotein B levels, a key marker for cardiovascular health.

In response, the companies whipped up a 20-ingredient, meal-replacement-style blend designed to target microbiome health, inflammation balance, blood-sugar stability and metabolic function.

The smoothie skips the “aesthetic-only” superfoods and shortcuts in favor of purpose-driven ingredients. The heavy-hitting list includes: unsweetened almond milk, flax and chia seeds, green banana, wild blueberries, pomegranate, cranberry, arugula, fresh herbs, walnuts, cold-pressed beet juice, ginger, Ceylon cinnamon, MCT oil, blended omega oils, BCAAs, creatine, and a single-ingredient plant protein derived from chocho beans grown high in the Andes.

In an industry built on superfood hype and one-size-fits-all claims, Function co-founder and CEO Jonathan Swerdlin says it’s time for a reality check.

“This isn’t about one more product on a shelf,” said Swerdlin. “We are challenging the idea that ‘healthy’ can be reduced to a label.”

“No shortcuts,” the company promises.

The smoothie comes with a QR code dangling from each bottle, offering buyers $25 off a Function membership. The pitch? Don’t just drink your health — measure it.
