By 2021, declining insurance reimbursements threatened his business despite increasing prescription volume. He turned to social media to share practical, affordable health advice, eventually building an audience of&nbsp;more than six million followers. Now, he explains what his experience behind the pharmacy counter taught him about medication side effects, nutritional deficiencies, supplement quality, and why conventional healthcare often overlooks individual biology.&nbsp;The conversation examines&nbsp;common multivitamin mistakes, including the use of synthetic folic acid and pyridoxine (vitamin B6). Phil explains why certain nutrient forms may be less suitable for some individuals, how excessive B6 intake can cause peripheral neuropathy, and why buying more supplements doesn't necessarily improve health. They explore&nbsp;MTHFR genetic variants, methylation, and folate metabolism, including potential implications for cognitive function, inflammation, blood pressure, fertility, and neurological development.&nbsp;Phil also reveals why&nbsp;creatine is his favorite supplement, discussing its potential benefits for brain health and muscle performance. He and Dave examine creatine dosing, hydration, electrolytes, absorption, and why creatine supplementation can influence kidney-related blood test results.&nbsp;The discussion turns to&nbsp;Big Pharma, prescription drug pricing, and pharmacy benefit managers (PBMs). Phil shares how insurance reimbursement practices threatened his independent pharmacy despite increasing prescription volume. They also explore compounding pharmacies, customized hormone formulations, injectable vitamins, GLP-1 medications, and the challenges of providing personalized treatment within the conventional healthcare system.&nbsp;Finally, Dave and Phil examine&nbsp;personalized medicine, genetic testing, medication interactions, and nutritional deficiencies, including the relationship between statins and CoQ10. They discuss why individual biology should guide supplement choices and how addressing underlying metabolic processes may offer a more comprehensive approach to long-term health.&nbsp;This episode is essential listening for anyone interested in multivitamins, methylated B vitamins, MTHFR genetics, creatine, prescription drugs, supplement effectiveness, personalized nutrition, metabolic health, and longevity.&nbsp;You'll Learn:&nbsp;<ul><li>Why common multivitamins contain different forms of B vitamins, and how folic acid, folinic acid, L-methylfolate, and P5P differ&nbsp;</li><li>How MTHFR genetic variants influence folate metabolism and why individual responses to supplements can vary&nbsp;</li><li>What Phil recommends considering when using creatine for brain health, muscle performance, hydration, and kidney-related blood testing&nbsp;</li><li>How pharmacy benefit managers, insurance reimbursement, and drug pricing affect independent pharmacies and patient care&nbsp;</li><li>Why compounding pharmacies create customized medications, including hormone formulations, injectable vitamins, and certain GLP-1 treatments&nbsp;</li><li>How personalized supplementation, nutrient testing, medication interactions, and genetics may help inform more individualized healthcare decisions&nbsp;</li></ul>Dave Asprey&nbsp;is a four-time New York Times bestselling author, founder of&nbsp;Bulletproof Coffee, and the&nbsp;father of biohacking.
