The Best Supplements for Athletes: How to Choose Quality and Avoid Low-Grade Options

There are hundreds of supplements on the market today, and it can be overwhelming to figure out which ones are worth your investment.
I used to be very cautious about what I spent money on, especially as I transitioned from being a student-athlete to a full-time professional athlete, without a steady income. I was careful with every purchase.
But as a very wise German man once said...
“Would you put regular oil in a Ferrari?”
It’s a simple analogy, but it’s one that really stuck with me. You train your body hard, pushing it to its limits and expecting peak performance, so why wouldn’t you fuel it with the best possible supplements?
While it’s difficult to always eat perfect, high-quality foods, one thing that’s easy to control is the quality of the supplements you consume.
My Go-To Supplements for Peak Performance and Recovery
As an athlete who is tested almost monthly for doping, it’s essential that I’m cautious about what I put into my body. That’s why I only choose supplements that are third-party tested—quality and safety are non-negotiable. As I’ve learned over the years, when it comes to supplements, you get what you pay for, and I’m willing to invest in the best.
ATP Lab has been my go-to brand for years. In fact, I’ve recently partnered with them (woohoo!) to promote the products I trust. (MITCHELL10 - for 10% off) They offer a wide range of supplements, from protein powders to multivitamins to powdered greens.
What sets ATP Lab apart? About 70% of their products are "Informed Choice" tested, which means I can confidently take them, knowing they meet the highest standards of safety and quality. And 100% of their products are crafted with top-tier ingredients that I trust.
The Supplements I Use Every Day
Here are the key supplements I use as part of my daily routine:

How to Choose the Right Supplements for You
It’s important to do your research and understand what your body truly needs. No two athletes are the same, and finding the supplements that work best for your specific goals and needs is key. In an ideal world, you’d get all the nutrients your body requires from food. But let’s face it—life is busy, and sometimes, a little extra support goes a long way.
A Quick Tip from Me:I used to get sick a lot, especially after races and travel. But I’ve found that since I started consistently taking my multivitamin, I haven’t gotten sick. Knock on wood—I don’t want to jinx it—but I now swear by this daily habit. Sadly no more gummy multivitamin candies haha.
