“Everyone is magnesium deficient, and topping up fixes anxiety, sleep and cramps overnight.”

Primary sourceSource matched
National nutrition-intake data + the pooled insomnia trials (Mah & Pitre, 2021). Intake data measures how much people eat, not a clinical deficiency rate. Low intake is common; diagnosed deficiency is not. The sleep trials show a modest, low-certainty effect on sleep onset of about 17 minutes, not an overnight fix.
Doctor review
Claim overstated. The source does not support “everyone,” and it shows no overnight effect on those symptoms. Rephrased to match the data.
Read and accepted by the accountable physician
Published verdict
Overstated
Intake is often low, but not everyone is deficient, and a supplement does not fix anxiety, sleep and cramps overnight.

Overstated
Do You Actually Need a Vitamin D Supplement If You Get Sun?

For a healthy adult with ordinary outdoor sun exposure, no — the large randomised trials found nothing worth buying. The supplement earns its place in specific at-risk groups, and the threshold that labelled everyone else deficient moved before the biology did.

Read the answer Overstated
Does Cold Plunging Raise Testosterone?

No. The reasoning behind the claim is anatomical rather than measured, and where circulating testosterone has actually been sampled after cold-water immersion it did not rise — if anything the post-exercise response was blunted. Cold water does other things reliably; this is not one of them.

Read the answer Partly true
Does Colostrum Survive Your Stomach?

Partly. A fraction of bovine IgG does survive gastric digestion and reach the intestine intact, where it can act locally. What does not happen in an adult is absorption into the bloodstream — the window that allows that closes within a day of birth, and it closes in calves, not in you.
