EP 1451
1451. You’re Taking the WRONG Vitamins (And Wasting Your Money)
Host Dave Asprey sits down with pharmacist Phil Cowley, founder of Cache Valley Pharmacy and creator of Phil’s My Pharmacist, to explore multivitamin mistakes, supplement effectiveness, MTHFR genetics, methylated B vitamins, creatine, prescription drug risks, and personalized medicine. Phil explains why common multivitamins may contain less suitable forms of certain nutrients, including synthetic folic acid and vitamin B6, and how genetic differences can influence folate metabolism, methylation, and individual supplement needs. They examine the potential benefits of creatine for brain health and muscle performance, including dosing, hydration, and its effects on kidney-related blood tests. Dave and Phil also discuss how pharmaceutical drugs originate from natural compounds, why pharmacy benefit managers threaten independent pharmacies, and how compounding pharmacies customize medications, hormones, and GLP-1 treatments. The conversation explores medication interactions, statins and CoQ10, genetic testing, and why tracking biomarkers over time may provide better insights than relying on individual lab results. Finally, Phil shares his predictions for the future of pharmacy, including AI-driven prescription dispensing, declining access to pharmacists, and the growing importance of personalized healthcare.

Host Dave Asprey sits down with Phil Cowley, a pharmacist, founder of Cache Valley Pharmacy, and creator of Phil’s My Pharmacist, to explore multivitamins, prescription medications, supplement effectiveness, MTHFR genetics, methylated B vitamins, creatine, and the hidden problems within modern healthcare.
After opening his pharmacy in Logan, Utah, in 2001, Phil spent two decades serving patients and dispensing millions of prescriptions. 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 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.
The conversation examines 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 MTHFR genetic variants, methylation, and folate metabolism, including potential implications for cognitive function, inflammation, blood pressure, fertility, and neurological development.
Phil also reveals why 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.
The discussion turns to 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.
Finally, Dave and Phil examine 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.
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.
