Supplement Recommendations in Greenville, SC
Supplement Recommendations at IHP Greenville. Dr. Hendry, DAOM — functional medicine, root-cause diagnostics, personalized care. Call (864) 365-6156.
Most patients who come in carrying a bag of supplements are spending money without knowing what they're actually taking. Magnesium oxide has 4% bioavailability — the patient buying it to help their insomnia and muscle cramping is essentially taking nothing. Folic acid in a patient with MTHFR polymorphism doesn't just fail to work — unmetabolized folic acid impairs natural killer cell function. The clinical harm from wrong supplement forms is real. I review the entire regimen, identify what to keep, what to stop, and what form substitutions are necessary. Then I prescribe specifically, from testing findings, at therapeutic doses from manufacturers with HPLC-verified constituent profiles. The supplement recommendations leave with you at the appointment.
How Supplement Recommendations Works
Supplement consultation involves reviewing your current supplement regimen, identifying what to keep (evidence-supported for your specific condition at appropriate doses from quality manufacturers), what to discontinue (redundant, contraindicated, or ineffective for your presentation), and what to add (based on identified deficiencies and therapeutic goals). Dr. Hendry then recommends or dispenses professional-grade supplements from our in-house dispensary.

Professional Supplement Guidance vs. Retail Supplement Industry Standards
The retail supplement market operates under the Dietary Supplement Health and Education Act (DSHEA) of 1994, which does not require pre-market efficacy or purity testing by the FDA. A 2015 investigation by the New York State Attorney General using DNA barcoding found that four of five major retail herbal supplement products from large pharmacy chains contained little or no DNA from the labeled botanical species, with most samples containing only rice, houseplants, or undisclosed fillers. This is not an anomaly; it reflects a structural absence of mandatory independent verification. Third-party certification programs — NSF International, USP Verification, Informed Sport — address this gap by requiring independent laboratory confirmation of identity, potency, and contaminant absence prior to certification. Practitioner-dispensary supplement lines additionally require evidence of bioavailability-optimized forms: magnesium glycinate rather than oxide, methylcobalamin rather than cyanocobalamin, 5-MTHF rather than folic acid. Ritz and Lord (MetaMetrix, 2008) framed this as a clinical imperative: the supplement recommendation is only as valid as the form and dose actually delivered to the patient. Professional guidance in this practice means reviewing current products the patient is already taking, identifying form or dose inadequacies, and replacing retail products with verified, clinically validated alternatives when warranted.
Research & Evidence
Professional-grade supplement guidance requires evaluation at four levels: ingredient identity verification, potency accuracy, bioavailable form selection, and absence of adulterants. These are not abstract quality standards — independent testing consistently reveals significant deviation in retail supplement products. Ritz BW and Lord RS (Laboratory Evaluations for Integrative and Functional Medicine, 2nd ed., MetaMetrix Institute, 2008) established the clinical framework for matching supplement recommendations to individual biochemical profiles derived from functional laboratory assessment. The most clinically significant example is folate metabolism: patients carrying the MTHFR C677T polymorphism — present in approximately 40% of the US population in heterozygous form — have impaired conversion of synthetic folic acid to the active 5-methyltetrahydrofolate (5-MTHF) required for homocysteine remethylation and DNA methylation. Recommending folic acid to this population is not merely ineffective; elevated unmetabolized folic acid in serum has been associated with impaired natural killer cell function. Holick MF (N Engl J Med, 2007) similarly documented that vitamin D3 (cholecalciferol) is substantially more effective at raising serum 25-hydroxyvitamin D than D2 (ergocalciferol) at equivalent doses — a form distinction that determines clinical outcomes but is rarely addressed in retail product labeling or consumer guidance.
Your First Appointment
Bring all current supplements with dosages — this is a clinical consultation, not a judgment. The goal is to optimize what you are taking based on evidence and your specific needs.
Why Dr. Hendry for Supplement Recommendations
Dr. Hendry's research training gives him the ability to evaluate supplement evidence critically — distinguishing between compounds with robust clinical evidence and those supported only by marketing claims.
