About Us

Products Built for You, With Your Goals in Mind.

Giant Sports International LLC began with a simple idea: create products that help people achieve balance between body and mind through science-backed nutrition and honest formulation. Founded in 2012 by three friends with more than seventy years of combined experience in sports nutrition, food science, and dietary supplements, GSI set out to change what consumers expect from performance products.

Our journey started with a single award-winning innovation Delicious Protein®, a whey protein that redefined taste, mixability, and quality. What began as a mission to make the best-tasting, safest, and most effective protein powder quickly evolved into something much greater: a full portfolio of fitness and wellness products designed for everyday people striving to feel, perform, and live better.

Over the past decade, Giant Sports has expanded from traditional fitness formulas into the ketogenic and low-carb space, releasing some of the best-selling keto-friendly products on the market. This shift reflects our belief that wellness isn’t one-size-fits-all. Whether your goal is to build muscle, boost energy, or live a balanced lifestyle, we’re here to provide solutions built on research, integrity, and results.

Today, as GSI, our commitment remains the same:
To create science-driven products that deliver noticeable value, with a focus on safety, taste, and real-world performance. We’ll never settle for being average if we can’t make a product that’s truly unique or best-in-class, we won’t make it at all.

Because at GSI, you’re not just a customer you’re the reason we innovate.
Better science. Balanced performance. Built for you and your goals.
