As if the darling of the alt-milk world, Queen Oat Milk, needed any more popularity points, Duchess of Sussex Meghan Markle, just threw her (very fashionable) hat in the ring. On Monday, Markle told Fortune about becoming a startup investor for Clevr Blends: a startup that makes instant oat milk lattes.

“This investment is in support of a passionate female entrepreneur who prioritizes building community alongside her business,” the duchess said. “I’m proud to invest in [Clevr Blends CEO Hannah Mendoza’s] commitment to sourcing ethical ingredients and creating a product that I personally love and [that] has a holistic approach to wellness. I believe in her, and I believe in her company.” This is the first time Markle has publicly acknowledged investing in a brand.

Mendoza’s brews combine the power of adaptogens, oat milk, and coconut cream without any dairy or added sugar. For now, you can snatch them up in flavors that include matcha, chai, golden (made with turmeric), and coffee for whatever your tastebuds want that day. And while all four of these ingredients come power-packed with their own benefits, let’s talk about oat milk for a sec.

“Compared to other alternative milks like hemp, flax, coconut, almond, cashew, or rice, oat milk generally has more protein,” said registered dietitian Tracy Lockwood Beckerman, RDN, on Well+Good’s YouTube series You Versus Food. “Oat milk has more fiber compared to cow’s milk and other alternative milks—specifically from beta-glucan fiber, a super dietary fiber found in oats that’s been celebrated for its cholesterol-lowering properties.”

Hey, if I had the money to invest in oat milk—I would follow Markle’s lead. For now, I’ll just have to sip these beverages knowing that they’re duchess-approved.
