Digital Health Literacy

Most of the health advice you see online is sold to you. Some of it is good. Most of it is not. Telling the two apart is a skill, and it is the skill this section is here to teach. We are not anti-supplement. We are anti-guessing. The goal of this section is to help you spot the patterns that wellness brands and influencers use, so you can make better choices with your money and your body.

Why we built this

Every week, patients bring us bottles, screenshots, and TikTok clips. Many of them have been told their problem will be fixed by a supplement, a peptide, or a powder. Sometimes that is true. Most of the time, it is not. We wanted a clear, plain place to send people that does not insult their intelligence, but also does not pretend the supplement industry is honest.

The series

The series is tiered. The plain-language summary lands the headline. The deeper clinical pieces go to the evidence base.

Start here (plain-language summary)

• Why Most Supplements Don't Work (And Why You Still Feel Better) - written for the reader who wants the headline in plain English. The placebo effect is real and powerful. The bottle is often lying. Here is how to think about both.

Deeper clinical pieces

• The Placebo Effect, Social Media, and Why Supplements Feel Like They Work - the mechanism deep-dive. Endogenous opioid, dopaminergic, and endocannabinoid pathways. The 54% contextual-effect meta. Why social media amplifies expectancy at scale.
• Quality and Contamination: What's Actually in Your Supplement - the buyer-beware data. FDA tainted supplements database. 57% Amazon mislabeling, 74% CBD label deviation, botanical adulteration rates from 17% to 57%. How to actually vet a product.
• Peptides: What's Approved, What's Gray Market, and What's Dangerous - the clinical guide to the peptide universe. FDA-approved GLP-1 RAs vs. gray-market BPC-157, TB-500, CJC-1295, MK-677. What we prescribe, what we do not, and why.

The pattern this series is teaching

Across every piece, the same three filters keep appearing. We use them in clinic with every patient, every bag of supplements, every wellness trend that comes through the door:

1. What problem is this trying to fix? If the answer is a generic feeling (energy, focus, "wellness"), the placebo response is probably doing most of the work.
2. Can we measure that problem? Objective biomarkers (25-OH-D, ApoB, HbA1c, RBC magnesium, Omega-3 Index, hs-CRP, homocysteine, MMA) are largely immune to placebo and are the only honest way to evaluate whether a supplement is doing what the label claims.
3. Is the product clean and dosed in a way that has been studied? Look for third-party verification seals (USP, NSF, ConsumerLab, IFOS), skip proprietary blends, and be skeptical of brands sold only through social media.

If a supplement fails any of those filters, the chance that the benefit you feel is mostly placebo + variable pharmacology goes up sharply. That does not mean the relief is fake. It means the supplement may not be doing the work you are paying for.

How to use the series

• If you are a patient: start with the plain-language summary. Bring the bottles, screenshots, or links to your next visit.
• If you are a clinician: the three deeper pieces are designed to be skimmable evidence anchors for the conversations you are already having. References are numbered with anchors.
• If you are a friend or family member trying to talk to someone about a supplement they are using: the placebo piece is the one that lands the mechanism without dismissing the experience.

This series will grow. When the next major wellness trend or supplement category shows up in the exam room often enough, we will add a piece.
