Algae-based protein is way more expensive than soy protein—like 5 to 10 times more—so even though it's better for the planet, it's too costly to make on a big scale right now.

Advancements and challenges in microalgal protein production: A sustainable alternative to conventional protein sources

Narrative Review

2025 Mar 10

The study agrees that making protein from microalgae is still much more expensive than using soy, which makes it hard to use on a large scale, even though it's better for the environment.

Similar Assertions

Growing protein from tiny algae uses way less land and water than raising cows — like 95% less land and way less water — so it could be a smarter way to make food without hurting the planet.
