Colostrum & IgG
Bovine colostrum standardized for immunoglobulin G. The number that matters is the disclosed IgG dose — and most labels won’t show you one.

Judge the ingredient, then the formula
Every explainer answers the same four questions in plain language: what is it, what has research actually examined, what doses did those studies use, and what should you look for on a label before paying for it.
Publishing honestly: the first explainers are being written alongside our next report wave. Nothing below links anywhere until it’s published — we don’t do placeholder pages. Subscribers get each explainer first.
The library
Ingredients we’re covering first
Chosen because they anchor the categories we review — and because they’re where label claims and study doses most often part ways.
Creatine
The most-studied sports supplement in existence. The open questions aren’t whether it works — they’re form, dose and the price you should refuse to pay.
Electrolytes
Sodium, potassium and magnesium in a stick pack. The label question: real replacement doses, or flavored water with a hydration story?
Magnesium glycinate
The gentler magnesium form — but “magnesium glycinate” on the front doesn’t always mean glycinate in the capsule. Elemental dose is the number to find.
Ashwagandha
An adaptogen with real trials behind specific extracts at specific doses — and a market full of products matching neither.
Omega-3
Fish oil lives and dies on EPA/DHA per serving, oxidation and testing — not on the size of the softgel count on the front.
Vitamin D3
Cheap, well-studied and widely underdosed or overpriced. What the IU number means and when testing actually matters.
Collagen
Hydrolyzed peptides with growing research on skin and joints — plus grams-per-serving math that makes some pretty tubs very expensive protein.
Whey isolate
Protein’s reference standard. The label tells you everything if you know where to look: protein per serving, per dollar and what’s padding the rest.
How explainers get written
Same standard as our reviews: claims matched to published research, study doses stated with sources, and the date every fact was checked. Where the evidence is weak or mixed, the explainer says so plainly.
Not medical advice
Explainers describe what research has examined — they don’t prescribe. Talk to your clinician before starting any supplement, especially alongside medication. Medical disclaimer.
