About the Reviewer

Hi, I’m Rebeca.
I review supplements honestly.

Every week I talk to people who spent $60, $80, $120 on a supplement that did nothing. Some of them were dealing with real health struggles — blood sugar issues, exhaustion, extra weight that just wouldn’t move. They weren’t looking for miracles. They just wanted something that actually worked. That gap between desperation and disappointment is why this site exists. My job is to stand between you and a bad purchase — and point you toward the ones that have real science behind them.

My Story

Why I Started Reviewing Supplements

It started during my Master’s program at Stanford. I was studying nutritional biochemistry, and I kept seeing a pattern: products marketed with scientific-sounding labels were using ingredients at doses so low they couldn’t possibly do what the label claimed. The gap between what companies promised and what the science actually supported was enormous.

After graduation, I spent two years consulting for healthcare providers, helping them interpret supplement research for their patients. I realized most people had no way to access this kind of analysis — it was buried in academic papers and behind expensive consultations.

So I built HealthWellnessReviews.com. A place where anyone can get the same quality analysis I was giving to clinicians — in plain English, for free. Every review follows the same rigorous protocol I developed during my research years: ingredient verification, dosage analysis, bioavailability assessment, and cross-referencing with PubMed-indexed clinical trials.

I accept no payment from brands. I never have. My income comes from affiliate commissions — when you buy a product I genuinely recommend, I earn a small percentage at no extra cost to you. That’s the only financial relationship I have with any company I review.

Credentials & Background

What Qualifies Me to Review Supplements

M.S. Nutritional Sciences — Stanford University
Graduate research focused on micronutrient absorption, metabolic health, and the pharmacokinetics of dietary supplements. Thesis on bioavailability optimization in nutraceutical formulations.
500+ Peer-Reviewed Studies Analyzed
Every review draws on primary research from PubMed, Cochrane, and major clinical databases. No secondary sources, no press releases, no manufacturer-sponsored studies taken at face value.
8+ Years in Supplement Research
From academic research to clinical consulting to independent reviewing — I’ve analyzed supplements across every major health category, including weight management, metabolic health, cognitive support, and oral health.
Zero Brand Sponsorships — Ever
No company has ever paid me to write a positive review. My affiliate relationships are disclosed on every page. A product earns a high rating by passing my analysis — not by paying for it.
My Process

How Every Review Is Built

Every supplement I review goes through the same four-step protocol I developed during my research years. No shortcuts, no exceptions.

01
Ingredient Verification
I start by listing every active ingredient on the label and cross-referencing each one against PubMed-indexed clinical trials. I’m looking for evidence of efficacy — not anecdote, not in vitro studies, not rat models. Human clinical trials.
02
Dosage Analysis
The most common way supplement companies deceive consumers is by using real ingredients at sub-therapeutic doses. I compare the label dose against the therapeutic threshold established in clinical research. A 50mg dose of something that requires 500mg to work is worthless.
03
Formulation Assessment
I look at the full formula: bioavailability of each ingredient form, potential interactions, proprietary blend transparency, and whether the delivery mechanism (capsule, tablet, liquid) actually supports absorption. The best ingredients in the wrong form don’t work.
04
Real User Outcomes
Science tells me if a product could work. Real users tell me if it does. I analyze verified reviews from multiple independent platforms — not the cherry-picked testimonials on a product’s own website. Then I reconcile what the research predicts with what users actually report.
My Commitment to You
“You deserve to know what’s actually in the bottle — and whether it’s worth your money.”

The supplement industry is worth over $150 billion. A small fraction of that goes to products that actually work. My job is to help you find that fraction — and avoid wasting money on the rest. Every review I publish is my honest scientific assessment, period. If a product doesn’t pass my analysis, I say so — regardless of how popular it is or how much an affiliate commission might be worth.

Common Questions

FAQ About My Reviews

Do you accept payments from supplement brands?
Never. No brand has ever paid me to write a review, positive or otherwise. My only income from this site comes from affiliate commissions — a small percentage of sales if you buy a product I recommend, at no extra cost to you. This is disclosed on every page of the site.
What does your M.S. in Nutritional Sciences actually mean for supplement reviews?
My graduate training at Stanford focused on how nutrients and bioactive compounds behave in the human body — absorption, metabolism, excretion, and interaction effects. This means I can read a supplement label and evaluate not just whether the ingredients have research support, but whether they’re present in meaningful doses, in bioavailable forms, and in combinations that make biochemical sense.
How long does it take you to research a review?
Between 2 and 7 days per product, depending on complexity. The research phase alone — reading the clinical literature on each active ingredient — takes most of that time. But for many supplements, I go further: I use the product myself for several weeks before publishing. There’s no substitute for first-hand experience. Lab data tells me what should happen. My own body tells me what actually does. The final review only goes live when I’m confident in both.
Can I contact you with a product suggestion?
Yes — I genuinely welcome suggestions. Use the contact page to send me a product name and I’ll add it to my review queue. I prioritize products that readers are actively asking about and that have enough market presence to warrant a thorough analysis.
Do you update reviews after publishing?
Yes. Supplement formulas change, new research is published, and user outcomes accumulate over time. I review and update published analyses whenever significant new information is available. Each review shows its most recent update date at the top.
