Our Story

No proprietary blends

Legion supplements contain no proprietary blends, which means you know exactly what you're getting in each supplement.

The Science

Ingredients and doses backed by science

Every ingredient in our supplements is backed by peer-reviewed scientific research and is included at clinically effective levels.

That means the ingredients and doses in our supplements are based on published scientific research demonstrating real benefits, not the restrictions of razor-thin production budgets or gluttonous profit margins.

While everyone claims to have the best supplements on the market, we can actually back it up with real science and real numbers.


100% naturally sweetened and flavored

Legion supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

No matter what you decide to buy, you're always protected by our ironclad, 100% money-back guarantee that works like this:

If you don't absolutely love our stuff for whatever reason, you get a prompt and courteous refund. No forms to fill out or hoops to jump through.

That means you can say "yes" now and decide later. You really have nothing to lose.

What the Industry Experts Are Saying

  • There are a lot of sleazy supplement companies out there, but Legion is not one of them. Their products are free of fillers and inactive ingredients and they take the time (and money) to test them with independent labs to ensure you're getting what you pay for.

    Dr. Spencer Nadolsky

    Author and founder of and
  • Legion produces products based on scientific data that will produce measurable benefits. Additionally, they put their money where their mouth is and are actively funding sports nutrition research at AUT that's unrelated to their products, purely to help advance our field.

    Dr. Eric Helms, PhD

    Published Scientist, Natural Bodybuilder, Coach, and Educator
  • Legion makes clean products. Period. The Legion line is something you can consume guilt-free, without any hidden fillers, artificial sweeteners or chemicals. Better yet, it's designed not just for adequacy, but for performance. I highly recommend.

    Ben Greenfield

    CEO of Kion & New York Times bestselling author of Beyond Training: Mastering Endurance, Health & Life
  • When it comes to supplements, I will only use the best. I want to use natural and scientifically-backed ingredients that make my mind and body feel healthy and strong. I've tried many supplements over the years, but nothing has made me feel great like Legion supplements have.

The Man Behind the Brand

My name is Mike Matthews, and I'm a bestselling health and fitness author, and the founder of Legion Athletics.

My mission is to create health and sports supplements that set the standard by which other brands and products are judged . . .

. . . to help educate consumers on the science of supplementation so they can make better purchasing decisions . . .

. . . and to help reform the sports supplements industry by embodying the change I want to see: honest marketing, sound science, clinically effective dosages, and natural, safe, and healthy products.

The bottom line is I don't just want to sell you pills and powders. I want to change the supplement industry for the better.

Many companies offer a money-back guarantee because they know the majority of dissatisfied customers aren’t going to go through the hassle of actually returning the product to get their money back. We don’t play these games because we don’t have to, the quality of our products makes it unnecessary.

If you order any of our supplements for the first time and don’t like it, you can keep it. Just notify us and we’ll give you a full refund on the spot. No complicated forms and no return necessary.

To protect ourselves from fraud, the It’s-On-Us guarantee is only valid for first time purchases of a product, and redeemable up to three months after purchase. If you bought more than one bottle of a supplement on your first purchase and don’t like it, we would ask that you send the unopened bottles back to us for a refund because we can put them back into our sellable inventory.


Many companies use shipping and handling fees to increase their profit margins, but here at Legion, we hate profits so our shipping is 100% free!

Okay, we do dig on profits, but we also do offer 100% free shipping to everywhere in the world because it makes people you like happy, and that makes us happy.

So, if you live in the United States, your order ships free regardless of order size, and if you live anywhere else, your order ships free when it’s over $99.

Why the restriction on international orders?

Unfortunately shipping outside of the US is very expensive and if we didn't require a minimum order size, we'd lose a lot of money. That said, most customers spend about $100 with us each time they shop, so this setup is a win-win.
