Streams straight from the publisher. podnod never proxies or re-hosts episode audio.
Hook: It’s not the supplement on the label that matters — it’s the form your body can actually absorb. Original episode ~60 minutes, condensed to ~8 minutes. In this tight summary, host Gary Brecka explains why “expensive pee” happens and how bioavailability, solubility, and genetics determine whether nutrients reach your cells. Learn why creatine HCl can outperform monohydrate, why methylfolate beats folic acid for many people with MTHFR variants, and why magnesium glycinate absorbs without the laxative effect of magnesium oxide. You’ll get practical swaps (folic acid → methylfolate, cyanocobalamin → methylcobalamin) and actionable takeaways for supplements, genetics, and performance. Keywords: bioavailability, supplements, creatine HCl, methylfolate, MTHFR, magnesium glycinate, B12. Listen now to get the key ideas in minutes.
