Why Your Supplements Aren’t Working

About this video

In this short clip, Brecka argues many supplements fail because of bioavailability — the share of a substance that actually reaches the bloodstream in usable form. Brecka claims the industry prioritizes cost and shelf stability over forms the body can use, and that ingredient form, biochemistry, and genetics determine whether a supplement does anything at all.

Key takeaways

• Brecka defines bioavailability as the percentage of a substance that becomes available for the body to use
• Brecka claims many retail supplements use forms the body cannot readily use
• Brecka argues understanding bioavailability stops people wasting money on ineffective products
