What Makes Us Different?
As lifelong runners, we grew tired of supplement companies catering to bodybuilders, gamers or elite athletes while also pushing products with unproven ingredients or ineffective doses to make a profit.
Our mission is to cut through the outrageous claims and marketing nonsense to bring you the best evidence-based, cutting-edge supplements designed specifically to help you live healthier, feel younger, and perform at your best.
We dive deep on the science and only include the highest quality ingredients with research backed benefits.
It’s finally time for masters and endurance athletes to have supplements that work as hard as they do!
Clinically Tested & Proven Ingredients
Every ingredient in our products has multiple studies demonstrating a scientifically significant benefit or outcome.
We don’t include any fad or fancy sounding ingredients just to pad the label.
Every formula is critiqued and revised in accordance with feedback from independent scientific advisors to ensure proper efficiency.
Scientifically Optimal Doses
Underdosing or using proprietary blends to hide the ingredient amounts is a way many supplement companies try to save money.
Our products have scientifically efficacious dosages and we disclose the exact amount on every label
Only The Highest Quality Ingredients
Not all ingredients are created the same.
For example, ferrous bisglycinate and ferrous sulfate are both forms of iron. However, research has shown that bisglycinate is absorbed almost 2 x better.
Most supplement companies use the cheapest, least effective forms of these ingredients, many of which are not bioavailable. While they may cost more, we only use the highest quality and most effective forms of every ingredient.
