Magnesium’s not just a “sleep supplement” It’s involved in almost everything your body does But like any

what it claims

Magnesium is involved in nearly every bodily function, but the benefit only shows up if dietary intake is insufficient. The RDA is about 420mg/day for men and 320mg/day for women; when supplementing, skip citrate or oxide (poorly absorbed) and aim for 200-300mg/day of another form.

The cited RDA figures are accurate (420mg men / 320mg women per US authorities), and the "benefit depends on your starting deficit" framing matches the literature.

The cited RDA figures are accurate (420mg men / 320mg women per US authorities), and the "benefit depends on your starting deficit" framing matches the literature. However, lumping citrate in with the "poorly absorbed, you pee most of it out" forms is a factual error: bioavailability studies (urinary and serum measurement) actually show magnesium citrate is one of the BETTER-absorbed organic forms (roughly 25-33% versus about 4% for oxide) — citrate has outperformed oxide, and sometimes even glycinate, in several crossover trials. The advice wrongly conflates citrate with oxide, which is indeed the poorest-absorbed form. The rest (recommending chelated/organic forms, food sources) is solid.

What the graded evidence says

Linked to, not proven to cause.

Effect: sleep / BP where intake is low — modest
Measured on: adults, especially with low intake

Best when you're actually low; not a universal sleep fix.

More from Tony

Progressive overload isn't a technique you 'apply', it's what happens when you train hard, near failure, with good form, repeatedly — rep ranges (3-5 for heavy lifts, 5-10 for secondary work, 10-20 for isolation) are a framework, not the cause.

holds upTony

There's no real per-meal ceiling around 20-30g of protein: your total daily intake matters far more than perfect distribution.

Others on this

The buzz from a Monster Energy comes almost entirely from its caffeine (and the sugar riding along with it) — the taurine and the B-vitamin megadoses on the can don't add a proven benefit beyond that.

Extreme, prolonged sun deprivation — like months aboard a nuclear submarine — is exactly the scenario where routine vitamin D supplementation makes real sense: several studies on submarine crews (Royal Navy, US Navy) show levels drop markedly within weeks without it.

holds upPaul McNally

For women in their 20s: four basics are enough — omega-3, vitamin D3, magnesium glycinate, and a quality probiotic — rather than 15 supplements.

Taking 2 magnesium tablets before bed is billed as a sleep "cheat code."

Vitamin D3, magnesium, omega-3s, and probiotics are presented as essential dietary supplements for optimal health.
