This protein bar helped fuel Rory McIlroy’s 2025 Masters win

Like many golf fans who are fighting those post-Masters blues, I was rewatching the final round of the 89th Masters the other night when something caught my eye. Before teeing off on the 72nd hole, Rory McIlroy took a bite of a protein bar. To most, it was just a snack. But as someone who knows how razor-thin the margins can be between victory and heartbreak, my curiosity was piqued.

After a quick investigation, I learned McIlroy’s fuel was a Transparent Labs Grass-Fed Protein+ Bar. Why does McIlroy favor this bar for his on-course nutrition? To the ingredients!

The first thing that jumped out was that Transparent Labs focuses on complete nutrition. Each bar includes 15 grams of complete protein, 15-17 grams of healthy fats and wholesome carbohydrates. They’re also packed with grass-fed whey and egg-white protein.

According to Transparent Labs’ website, these two protein sources are among the best for muscle recovery. Grass-fed whey delivers essential amino acids and branched-chain amino acids (BCAAs) that support optimal muscle repair and growth. Egg-white protein offers similar benefits, plus B vitamins and selenium — nutrients shown to increase energy, support brain function and even reduce oxidative stress.

In other words, the kind of stuff your body needs when you’re battling it out for the green jacket.

These nutrients don’t just prevent muscle breakdown and boost energy on the course, they also aid in post-round recovery, which means McIlroy can show up Sunday feeling fresh and ready to hit monstrous tee shots.

Transparent Labs also leaves out artificial sweeteners, fillers or dyes, ingredients that typically make protein bars hard to digest. But that doesn’t mean they’ve sacrificed flavor. Instead, they sweeten products naturally by adding ingredients like dates and dairy-free chocolate to create a bar that’s tasty and doesn’t compromise your fitness goals.
