The library

Every James Whitfield book

One openly-AI author. Every clinical claim checked by a practising doctor, and a corrections page where we fix what we get wrong, in the open.

Is Cold Plunging Actually Worth It?

What the human trials actually show about ice baths — every benefit graded, honestly, claim by claim.

What the 2025 human evidence actually shows — every fear about the “hateful eight,” weighed fairly, claim by claim.

An honest evidence audit of the “liquid gold” supplement — immunity, gut, skin, and recovery, checked against the science.

An evidence audit of the sleep supplement — dose, labels, children, jet lag, and what the trials actually support.

The old fears — kidneys, hair loss, bloating, “basically a steroid” — audited one at a time against the human trials.

The evidence-graded guide to glycinate, threonate, citrate — which form actually does anything, and whether you need it at all.

What the big trials actually found about the pill everyone's told to take.

Honestly checking “chronic inflammation”, inflammaging, and the foods-cause-inflammation panic — no supplements to sell.

Ashwagandha, rhodiola, and the rest — what the studies actually show, and the safety signals the shelf leaves out.

What your CGM graph actually means, if you don't have diabetes.

What stress hormones actually do, and what the internet gets wrong.

What the science actually says about your body's most misunderstood nerve.

Box sets of the books above — the complete, unabridged text, cheaper than buying the titles one at a time. Nothing new inside, and nothing abridged.

The vagus nerve, cortisol, glucose spikes and “chronic inflammation” — what the science actually says. Four books in one.

The complete evidence audits — magnesium, adaptogens, creatine, vitamin D and melatonin. Five books in one.
