One guide per formula in our apothecary. Written by our pharmacist. No incentivized reviews, no affiliate links, no "five reasons why" listicles. What it is, what it isn't, when to take it, when not to.
Each entry in the PuraVigor Journal is one formula from the apothecary, written up by our in-house pharmacist after she has read every meta-analysis published on the molecule in the last fifteen years. The format is fixed: what it is, what the evidence actually shows, what dose the studies used, when not to take it, and what it pairs with. No five-reasons-why listicles. No "clinically proven" without a citation. No affiliate links to anyone — including ourselves.
Where the evidence is strong (magnesium for sleep, creatine for muscle, vitamin D for deficiency), we say so. Where it is mixed (collagen for hair, ashwagandha for testosterone, sea moss for anything), we say that too. The point of an honest journal is not to sell the next bottle — it is to be the page you can still send your sister.
Filter by need — sleep, energy, women's, men's, kids — using the chips above, or search by molecule name. Each guide averages 3,400 words and cites between two and twelve peer-reviewed studies (we link DOIs, not summaries). News articles cover the same week's meta-analyses, written in plain English with the actual effect size, not the press-release version.
Updated quarterly as new evidence lands. If a study changes our recommendation, the guide gets a dated revision note at the top — not a silent edit. The whole archive is searchable, free, and will stay that way. The catalogue is over at the apothecary; the founder's note about why we run it this way is here.
