Not Medical Advice
The content published on herreramedical.org is provided for general educational and informational purposes only. It does not constitute medical advice, diagnosis, or treatment. The information on this site is not a substitute for the advice of a qualified, licensed healthcare professional who knows your individual medical history, current medications, and health conditions.
Do not rely on information from this website to make decisions about your health, medications, or supplement use without first consulting a qualified healthcare provider. If you are experiencing a medical emergency, call emergency services (911 in the U.S.) immediately.
Supplement Information is Not Treatment Guidance
Herrera Medical covers research on dietary supplements — vitamins, minerals, and amino acids — that have been studied in peer-reviewed literature in connection with specific aspects of health. Describing research findings is not the same as recommending a supplement for your personal use.
The supplements we discuss (zinc, vitamin D, L-arginine, niacin, magnesium, and others) are not FDA-approved treatments for any medical condition, including erectile dysfunction. The FDA does not evaluate dietary supplements for safety and efficacy in the way it evaluates prescription or over-the-counter drug products. Research showing an association between a nutrient and a health outcome does not mean supplementation will produce the same outcome in any individual.
Accuracy and Timeliness
We make a good-faith effort to ensure that the information on this site is accurate and current at the time of publication. However, medical and nutritional science evolves, and information that was accurate at the time of writing may become outdated as new research is published. We review and update articles on a periodic basis, and the date of last review appears on each article. We cannot guarantee that all information is current at the time you read it.
If you believe any content on this site contains a factual error or is outdated, please contact us at [email protected]. We take accuracy corrections seriously.
No Commercial Relationship with Supplement Companies
Herrera Medical does not sell dietary supplements or medications. We do not earn affiliate commissions from supplement purchases. We do not accept paid advertising from supplement companies, pharmaceutical manufacturers, or online retailers. Brand names mentioned on this site are mentioned for descriptive purposes only (for example, to identify a specific product form tested in a study) and do not constitute endorsements.
We have no financial relationship with any company whose products are mentioned on this site.
Third-Party Links and Resources
This site may link to external websites such as the NIH Office of Dietary Supplements, PubMed, Mayo Clinic, and other reputable health resources. These links are provided for reader reference only. Herrera Medical does not control the content of external websites and is not responsible for information found on third-party sites. Links to external sites do not imply endorsement of all content on those sites.
Individual Results Vary
Any health-related information presented on this site is based on population-level research. Individual responses to supplements vary based on genetics, baseline nutrient status, overall diet, medications, age, comorbid health conditions, and many other factors. Research findings that describe average effects in study populations cannot be assumed to apply to any specific individual.
Consult a Healthcare Provider
Before starting any new supplement, especially if you take prescription medications, have a diagnosed medical condition, are pregnant or nursing, or are over 65, consult with a licensed healthcare provider. A physician or registered dietitian can order relevant laboratory tests (such as serum zinc or 25-hydroxyvitamin D), review your medication list for potential interactions, and provide guidance appropriate to your personal health profile.
