For years, I’ve been asked for a simple list of the supplements I actually use and recommend. So here it is: my five non-negotiable essentials.

Each comes from a highly reputable company that goes above and beyond on quality. They’re all NSF Certified for Sport, meaning every single batch is independently tested to confirm that what’s on the label is exactly what’s in the product — and nothing more. In an industry that’s largely under-regulated, this certification is the gold standard, and I only choose brands willing to go through the hoops required to earn it.

These aren’t random affiliate picks. They’re the supplements I take daily — and the same brands I partner with on The Proof. My partnership criteria are strict:

  1. I must use (or be willing to use) the product personally.
  2. It must provide genuine value to you.
  3. Wherever possible, I negotiate exclusive discounts so you can access them at a lower cost.

When you purchase via the links below, you’ll save money and support the show — helping me keep evidence-based conversations free and accessible to everyone.
