Creatine for the brain, not just muscle
Creatine — familiar as a strength supplement — also supports brain energy metabolism, with reported benefits for memory, mood and cognition, including when you're sleep deprived. For neurodivergent people with disrupted sleep, it's a low-cost lever worth considering, with usual caveats about checking supplements with a professional.

Creatine is best known to lifters, but the brain takes it up too. It buffers cellular energy through the phosphocreatine system, helping maintain the ATP supply that neurons run on. That energetic role is the proposed basis for effects on memory, mood and cognitive performance.
One situation where the energy angle matters most is sleep deprivation. Lack of sleep depletes the brain’s energy reserves, and supplementing creatine raises the brain’s phosphocreatine pool, which may partly offset the cognitive energy deficit that follows a bad night — directly relevant to neurodivergent people whose sleep is often fragmented or delayed. The common form is creatine monohydrate. As with any supplement, the body generally handles food-form nutrients best and individual responses vary, so treat creatine as an adjunct, confirm it fits your health picture with a professional, and don’t expect it to substitute for actually protecting sleep.
