Ambrosia Collective launches first US protein powder made with Solein

Ambrosia Collective launched Planta Powered by Solein on June 9, bringing what it calls the first food product and protein powder in the United States formulated with Solein into the market. The ready-to-mix powder debuts under Ambrosia Collective’s Planta brand in Salted Caramel Cold Brew flavor, with 20 grams of protein per serving and 0 grams of sugar.

The launch matters because Solein is not another whey clone or a pea-and-soy remix. Solar Foods makes the ingredient through a bioprocess that grows a microbe using air and electricity, putting it in the emerging air-based protein lane that now sits alongside dairy, plant, fermentation and egg white proteins. For protein brands, that shifts the conversation from simply hitting macros to explaining sourcing, sustainability, allergen profile and convenience in the same tub.

Ambrosia Collective said the product would begin as test marketing in the United States, with a nationwide rollout planned for later in the summer. That staged approach gives the brand a chance to see whether shoppers will reach for a protein powder built around a source that does not depend on animals or conventional crops in the usual way. In a category crowded with powders promising cleaner labels and better digestion, the real test will be whether consumers pay for the story once the novelty fades.

Solar Foods said the new product marked the first consumer product made with Solein available in the United States, and that the Ambrosia powder would be among the first Solein-powered protein powder products available to consumers anywhere in the world. The company also said Solein had obtained self-affirmed GRAS status in the United States, a key regulatory step that opened the door for use in foods sold to shoppers.

The order behind the launch had been in motion for months. Solar Foods said in January 2026 that it had received an order from Ambrosia Collective for a Solein-powered protein powder, with a limited amount intended for consumers in the first quarter of 2026. By the June 9 debut, that plan had turned from ingredient curiosity into a branded product aimed at everyday protein buyers, the kind who now want more than a high number on the nutrition panel.
