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.

Natural

100% naturally sweetened and flavored

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

Our 100% Money-Back "It's-On-Us" Guarantee

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

Previous
  • 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 FatLossPrescription.com and LeanerLiving.com
  • 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 the author of Bigger Leaner Stronger, Thinner Leaner Stronger, and several other bestselling fitness books as well as the founder of Legion.

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.

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

Free Worldwide Shipping & Returns

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 go in for happy customers, and free shipping works like gangbusters.

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 $199.

Why the restriction on international orders? Unfortunately, shipping abroad is very expensive, and if we didn’t require a minimum order size, we’d lose a lot of money.

That said, as most international customers spend about $200 with us each time they shop, this setup is a win-win.

And 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.

Clinically Effective Doses

Great ingredients aren't enough to make a great product—you also need correct doses.

That’s why we use the exact doses of every ingredient that have safely produced the desired benefits in peer-reviewed studies.

Made in USA

Where your supplements are made matters, because rules and regulations regarding quality and purity differ from country to country.

And if you want to ensure the supplements you’re swallowing every day are safe and effective, you want products produced in the USA.

That’s why all of our supplements are made in America in NSF-certified and FDA-inspected facilities that operate in accordance with the Current Good Manufacturing Practice (cGMP) regulations.

We pay a premium to work with the best manufacturers in the country, but it’s the only way we can also produce the best all-natural sports supplements.

Lab Tested

Did you know that studies have shown that many supplements contain dangerously high levels of toxins like lead, arsenic, and cadmium?

Not ours.

Every ingredient of every supplement we produce is tested for heavy metals, microbes, allergens, and other contaminants to ensure they meet the strict purity standards set by the FDA.

Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health and that more research is needed.

That’s why all of our supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

Science-Backed Ingredients & Doses

Unlike some supplement companies, we don’t sell dubious white labeled or off-the-shelf formulations.

Instead, our custom and unique formulations are the result of extensive reviews of the scientific literature to discover the most effective ingredients for each.
