Who We Are
Herrera Medical is an independent editorial team dedicated to translating peer-reviewed nutritional and medical research into accurate, accessible health information. We focus specifically on vitamins, minerals, and dietary supplements that have been studied in connection with men's health — with particular attention to the research on erectile function.
We are not a pharmacy, a supplement retailer, or a medical clinic. We do not sell products, accept paid advertising from supplement companies, or provide personalized medical advice to individuals. Our purpose is purely informational: to make published research easier to understand for people who want to learn about the evidence base before speaking with their own healthcare providers.
Our Editorial Standards
Every article published on Herrera Medical is evaluated against the following criteria before publication and at periodic review:
- Primary sources: We cite peer-reviewed research published in indexed medical journals. Where possible, we link to or identify the original study by author, year, and journal name so readers can verify our summaries.
- Hierarchy of evidence: We prioritize systematic reviews and randomized controlled trials over observational studies. When only observational data is available for a claim, we say so explicitly.
- Accuracy over optimism: We describe what the evidence actually shows, including its limitations — small sample sizes, short study durations, or industry funding — rather than overstating findings.
- Currency: Articles are reviewed and updated when significant new research is published. The date of last review appears on each article. Our review cycle for major articles is approximately every 18 months, or sooner if substantially new evidence appears.

Editorial Review Board
Medical Accuracy Review
Articles on Herrera Medical are reviewed by members of our editorial board, which includes individuals with training in clinical nutrition, general medicine, and health communications. Board members review articles for factual accuracy and flag claims that require stronger evidence or clarification. Board members are not paid endorsers and have no financial relationship with any supplement brand referenced on this site.
What We Cover
Our current content focuses on the following topics related to men's nutritional health:
- Vitamins and minerals studied in connection with erectile function (zinc, vitamin D, niacin, magnesium)
- Amino acid supplements with cardiovascular and sexual health research backing (L-arginine)
- How deficiencies in common nutrients affect testosterone, vascular health, and sexual function
- Practical guidance on supplement safety, dosing ranges, third-party testing, and drug interactions
We do not cover prescription medications in a promotional or sales-oriented capacity. Where prescription treatments are mentioned, it is for context — for example, to distinguish between FDA-approved drugs and over-the-counter supplements.
Independence and Funding
Herrera Medical is independently operated. We do not accept advertising, sponsorship, or affiliate commissions from supplement manufacturers, pharmaceutical companies, or online retailers. Our content is not influenced by commercial relationships. When we reference external resources (such as the NIH Office of Dietary Supplements, PubMed, or Mayo Clinic), we do so because they are authoritative, not because of any financial arrangement.
This site has no e-commerce functionality. We do not list "buy" links to specific supplement products, compare prices for commercial gain, or receive referral payments when readers purchase a supplement after visiting this site.
