Our Research Standards
Every recommendation on this site is the result of careful, science-backed research — because your health deserves nothing less than our very best.
Who We Are
Vitamins Women Guide was created with one purpose: to give women over 50 honest, research-backed supplement guidance they can actually trust.
We know how overwhelming the supplement world can be — thousands of products, conflicting claims, and marketing that preys on your concerns. That’s why every guide we publish follows a strict research process, rooted in peer-reviewed science and designed specifically for the needs of women in midlife and beyond.
Our content is written and reviewed by Sarah Mitchell, a dedicated health researcher and wellness advocate who has spent years studying the intersection of hormonal health, aging, and evidence-based nutrition.
Our Four Research Pillars
Every article and product recommendation we publish is built on four non-negotiable pillars:
Peer-Reviewed Science
We cite only real, published studies from PubMed and other reputable scientific databases. No anecdotes, no influencer claims.
Expert Medical Guidance
Our research is informed by leading physicians and researchers in women’s health, functional medicine, and longevity science.
Women Over 50 First
We only recommend products that address the specific hormonal, metabolic, and nutritional needs of women in midlife and beyond.
Full Transparency
We disclose all affiliate relationships clearly. Our editorial opinions are never influenced by brand partnerships or commissions.
How We Evaluate Every Supplement
Before any product earns a spot in our guides, it must pass a rigorous evaluation process. Here’s exactly what we look at:
- 🧬
Ingredient form & bioavailability — We assess whether the ingredient is in its most absorbable form (e.g., magnesium glycinate over magnesium oxide, ubiquinol over ubiquinone). The wrong form can make a supplement nearly useless.
- 🔬
Clinical evidence — We verify that the active ingredients are backed by real human clinical trials, not just animal studies or in-vitro research.
- ✅
Third-party testing & certifications — We prioritize products tested by independent labs (USP, NSF, Informed Sport) that verify purity, potency, and label accuracy.
- 📋
Label transparency — We reject products that use proprietary blends to hide ingredient doses. Every product we recommend shows exactly what’s inside.
- ⚠️
Safety & interactions — We flag potential interactions with common medications and conditions relevant to women over 50, including thyroid issues, hormone therapy, and statins.
- 💰
Value for money — We compare cost per serving across quality tiers so you can find the best option for your budget without sacrificing efficacy.
- ⭐
Real user feedback — We analyze verified customer reviews to identify real-world patterns in effectiveness, tolerability, and side effects.
