Are you curious about supplements like creatine or electrolytes?

When you should consider taking them?

Or maybe wondering what supplements are more hype than actual help?

If so, you’re going to love this week’s podcast with Christina Chu!

Christina is a Boston-based sports dietitian and CEO of Christina Chu Nutrition LLC.

She supports athletes from youth baseball to professional combat athletes through individual nutrition counseling and team talks.

And today, we’re going to take a deep dive into supplements, and what YOU should consider taking – as well as what you NEED to save your money on!

 

Quotable Quotes:

Supplements are supplemental to your diet. It’s quite literally in the name, in case you ever forget.

—–

It’s what’s on the inside that matters, not the outside. So the branding could look really pretty, but it’s the quality of the products that matters the most.

—–

You can’t out supplement a bad diet no matter what.

 

This Week on the Physical Prep Podcast:

  • Why supplements should complement a well-rounded diet, not replace it.
  • The key components or big rocks of what Christina considers a “balanced” diet.
  • How a lack of regulation can make for some crazy claims, and why third-party testing of supplements is so critical.
  • The power of creatine for both muscle building AND cognition.
  • Why Omega-3’s aren’t sexy, but still incredibly helpful and protective to the body.
  • Caffeine: How much is enough? And how do you optimize both timing AND dosage?
  • Christina’s list of supplements that are probably more hype than actual help.
  • Thoughts on consistency and long-term success with any nutrition or supplementation program.
  • The evolving research in sports nutrition, and why there’s never any shortage of topics to dive into!
