ATH (ay - ti - eich n.) is the abbreviated version of "athletics."

Headquartered at 449 Cooke Street in Honolulu, Hawaii, the brand is the offspring of my three passions: Jiu Jitsu, surfing and lifting weights. After returning home from a short stint playing professional baseball in 2012, I couldn't find a sports nutrition company that used clean ingredients AND designed products for athletes. So I decided to build it myself.

At first I had no intention of creating an actual company. All I wanted was high quality, clean supplements to help me train. I ordered 50 pound bags of raw ingredients and mixed the first batch in the kitchen. At the time (and still), supplements had a laundry list of artificial ingredients and left a bad after taste. Our powders were different. They were made with clean ingredients: grassfed protein, natural flavors from food sources (like cocoa powder), and a touch of natural sweeteners (like stevia and lo han fruit extract).

After selling out a few times, I figured it was time to find a legit manufacturer to package it for us. We had to create products that our customer actually wanted (we had to pay off our credit card) and ensured our growth was entirely crowd-funded. By doing so we were able to cut out the middle man and pass the savings on to our customers.

Since then we've grown across the nation to athletes, aspiring athletes, and anyone who is looking for sport supplements made from clean ingredients...
