Born to Compete. Built to Help You.
From the dugout at Stanford to the boardroom — meet the athlete and engineer behind Athletica Naturals.
Hi, I'm Missy Penna.
I grew up surrounded by health and wellness — my dad owned a health food store, and from a young age I was stocking shelves, learning ingredients, and talking to customers about what actually works.
But I was also an athlete. I played volleyball, basketball, and softball all through middle and high school, and went on to pitch at Stanford University, where I earned my degree in Engineering. I knew what it felt like to push your body to its limits — and to reach for supplements that were never designed with you in mind.
That gap between what female athletes need and what the industry actually offers? That's exactly why I built Athletica Naturals.
A Life Built Around Sport & Science
My dad's health food store was my second home. I grew up understanding nutrition from the ground up — not from a textbook, but from real conversations with real people looking to feel better and perform their best.
I played volleyball, basketball, and softball competitively from a young age. Growing up in Miami, I competed at a high level and quickly learned that what you put in your body matters as much as how hard you train.
I earned a spot on the Stanford softball team as a pitcher — one of the most competitive programs in the country. Alongside competing at the highest collegiate level, I pursued a degree in Engineering, learning to think in systems, solve problems, and never accept "good enough."
Softball took me around the world, competing at an international level. Traveling and competing globally sharpened my understanding of athletic performance — and reinforced how few quality options existed for female athletes looking for clean, effective supplementation.
After Stanford I spent a decade working as an engineer in the petroleum industry, applying the same analytical rigor I learned on the mound and in the classroom to large-scale technical problems. It taught me discipline, precision, and how to build things that actually last.
When the opportunity came to take over my dad's health food store in Miami, I knew it was time. I came back with an engineer's eye, an athlete's experience, and a mission: to build the supplement line I always wished had existed when I was competing.
Athletica Naturals is the result of a lifetime in sport, science, and nutrition. Every product is formulated the way I would have wanted as an athlete — clean, clinically dosed, and built around female physiology. No shortcuts. No compromises.
Built for the Woman Who Trains Hard.
Most supplements on the market are designed for men and relabeled for women. The dosages are wrong. The formulas don't account for female hormonal cycles, iron metabolism, or bone density needs. As a lifelong female athlete, I experienced this firsthand — and it wasn't good enough.
Athletica Naturals starts from scratch. Every formula is built around how the female body actually works, at clinically effective doses, with full label transparency and zero proprietary blends.
"I spent my whole career as an athlete reaching for supplements that weren't made for me. Athletica Naturals exists so no female athlete ever has to do that again."
