Slate

Slate makes shelf-stable, lactose-free protein shakes in aluminum cans, built around a simple idea: chocolate milk you can drink every day. Founders Manny Lubin and Josh Belinsky launched it in late 2019 with three chocolate flavors, following a Kickstarter campaign, a Shark Tank appearance, and hundreds of formula iterations.

The lineup has grown well past chocolate. Slate now runs 20g protein milk shakes and iced coffees, 30g and 42G ultra protein shakes, plus drink mix sticks and cookies. French Vanilla has become a fan favorite, and athletes keep naming it in their endorsements. The through-line is 0g added sugar, 1-3g net carbs, and added vitamins and electrolytes. It's a lane that sits between a sports recovery drink and a grab-and-go snack.

How the Formula Works

Slate starts with ultra-filtered milk. The filtration strips out lactose and some water, which concentrates the milk's natural proteins. The brand says that's how the cans hit their protein numbers without added protein powder. Sweetness comes from allulose and stevia rather than sugar. The 20g milk shakes and iced coffees are positioned as all-natural.

Because the cans are shelf-stable, you can stash them in a gym bag, desk drawer, or car and skip the fridge. Cold still tastes best. The aluminum packaging is recyclable, and Slate is a Certified Plastic Neutral company.

Who Drinks It

The audience is gym-goers, busy professionals, parents who want a cleaner chocolate milk for the family, and anyone cutting sugar without giving up flavor. Slate has leaned hard into athlete culture, with testimonials from UFC fighters, NBA players, and CrossFit competitors, and it is an Official UFC Partner. The tagline is "shamelessly chuggable," and the marketing backs it up. The pitch is protein that tastes like a treat.

Slate is a strong pick for anyone who wants a protein shake that drinks like dessert. It's one of the better-known names in the canned protein shake space, with a lineup wide enough to cover a light afternoon snack or a heavy post-workout refuel.
