Scientific literature widely supports the safety of creatine supplementation in healthy individuals, as confirmed by several meta-analyses and systematic reviews (e.g., International Society of Sports Nutrition). The notion that creatine damages the kidneys in healthy people is a misconception refuted by numerous clinical studies (RCTs). However, the advice of caution for those suffering from renal pathologies is relevant. Although creatine is not necessarily 'toxic' to them, it can skew markers of kidney function (such as blood creatinine), making medical monitoring complex. This is a prudent precautionary approach rather than evidence of direct danger. The creator here faithfully reports the current scientific consensus without sensationalism.

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.

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

Other advice in the Register that leans on the same research.

Creatine isn't just for muscle — at doses higher than the standard 3-5g, some reaches the brain and may support cognitive energy, especially under stress or sleep loss.

5g of creatine isn't enough, the claim goes: bumping to 10g raises brain creatine further, and a 25g dose counters the cognitive decline from sleep loss and the mid-afternoon energy crash.

After a year of daily creatine monohydrate: no hair loss, no kidney damage, the loading phase isn't necessary, and "special" creatine forms change nothing versus plain monohydrate.
