Why MoodSupplement exists

MoodSupplement started from a simple frustration: most pages selling mood supplements either over-promise wildly or bury the cautions that actually matter. We wanted a place that treats readers like adults — clear about what the research shows, honest about what it doesn't, and never pretending a capsule can replace real care.

Who we are

MoodSupplement is run by Enoch C., MSc — a graduate of the University of Groningen's MSc in Business Administration (Health), with training in health economics, healthcare systems, and evidence-based decision-making. That background is what drives the site: reading research carefully, weighing evidence honestly, and understanding how the supplement market actually works.

What MoodSupplement is not is a clinical practice. Enoch is not a doctor, registered dietitian, or pharmacist, and nothing on this site is medical advice. The site's role is research and translation — doing the legwork of reading the studies, and being transparent about the limits of what that research can tell you. There is currently no medical reviewer on staff; for high-risk topics such as 5-HTP and medication interactions, professional guidance is essential.

How we evaluate supplements

Every product on MoodSupplement goes through the same process before it appears here:

• We read the primary research. Not press releases or manufacturer summaries — the actual trials and meta-analyses. We note study type, sample size, effect size, and whether there are publication-bias concerns.
• We assign an evidence tier honestly. Each supplement is rated emerging, moderate, or well-studied based on the weight and consistency of human trials — not on how commercially promising it is. One favorable study means emerging, full stop.
• We apply a stated quality criterion to specific products. Our product recommendations aren't "the best seller." Each is the product that meets a published, sourced criterion — concentration, purity testing, formulation — that we verify by hand and date. If a formulation changes, we re-verify.
• We include the counterevidence. Where the strongest synthesis (a Cochrane review, a large null trial) doesn't support a claim, that finding appears alongside the supportive research. Cherry-picking is how supplement sites lose credibility.

How articles get written

Every new article must cite at least two primary sources (NIH, PubMed, DOI-linked trials, Cochrane) — our build system refuses to publish one that doesn't. Older articles are on a rolling refresh cycle that deepens citations and updates dosing details, with the revision date shown on the page. Where a page has been reviewed by a licensed professional, that reviewer is named on it.

Support framing, not treatment claims

We describe supplements as mood, stress and sleep support — never as a treatment or cure for depression or any medical condition. Supplements are a small, optional supporting piece of wellbeing; the foundations (sleep, movement, daylight, food, connection, and professional care when you need it) matter far more. Where a supplement needs real care — like 5-HTP alongside antidepressants — we say so loudly, up front, not buried at the bottom.

How we make money

MoodSupplement is reader-supported through affiliate links to Amazon. If you buy through one of our links, we may earn a commission at no extra cost to you. Affiliate income never changes our evidence ratings, our quality criteria, or which cautions we include — products that don't meet the stated criterion don't get recommended, regardless of commission. See our full affiliate disclosure.

Corrections

If you spot an error — a study we've misread, a product spec that's changed, a citation that doesn't check out — please tell us. We'd rather be corrected than wrong. Reach us via the contact page, and see our medical disclaimer for the full terms.

If you're struggling

The most useful thing a site like this can do for someone in genuine distress is point toward real help, not a buy button. If you are struggling, please see our Get help page.
