Building Muscle After 40? Here's What Actually Changes

Muscle building after 40 works a little differently than it did in your twenties, and that's true whether you're eating plant-based or not. The extra effort required has nothing to do with where your protein comes from.

What Actually Changes After 40

Starting around this age, research on age-related anabolic resistance shows your body becomes somewhat less efficient at using protein to build muscle. In practice, that generally means needing more protein per meal to trigger the same muscle-building response you'd have gotten from a smaller amount at 25. It's not a wall, it's a shift in how much input it takes.

Where Plant-Based Eaters Sometimes Fall Short

The issue usually isn't the "plant-based" part, it's total protein intake and consistency across the day. It's easy to get one solid protein-heavy meal in and coast on the other two. If you're training seriously after 40, spreading complete protein across three or four points in your day matters more than it used to.

What to Actually Prioritize

Two things do most of the work: a higher daily protein target than you think you need, and making sure that protein is complete, meaning it has all nine essential amino acids. Hydrolyzed pea protein checks that second box on its own, so building a plant-based diet around it doesn't require extra planning to "complete" it with other sources.

Where SURGE Fits

SURGE adds a clean 25g of complete protein per 30g serving at a point in the day you might otherwise skip, like mid-afternoon or right after a strength session, without adding a meal's worth of food. For a lot of people over 40, that extra touchpoint is what closes the gap.
