Taking a daily multivitamin for two years makes older adults' brains function as if they are two years younger, based on better memory and thinking skills.

How it works

Taking 5 grams of creatine daily for six weeks boosts energy storage in brain cells, helping them work better during mental tasks, and this works the same way whether someone eats meat or not.

In Simple Terms

Taking 5g of creatine daily for six weeks raises phosphocreatine levels in the brain, which helps neurons quickly regenerate ATP when they need energy, supporting thinking and memory functions.

Causal chain
1

Oral creatine monohydrate is absorbed from the gastrointestinal tract into the bloodstream

Verified by multiple studies
which leads to
2

Creatine crosses the blood-brain barrier via the creatine transporter (SLC6A8) and is taken up by neurons and glial cells

Verified by multiple studies
which leads to
3

Intracellular creatine is phosphorylated to phosphocreatine by creatine kinase using ATP

Verified by multiple studies
which leads to
4

During high neuronal energy demand, phosphocreatine donates its phosphate group to ADP to regenerate ATP

Verified by multiple studies
which leads to
5

Sustained ATP availability supports neuronal firing, synaptic transmission, and cognitive processing

Verified by multiple studies

Community contributions welcome

Direct test
Why it supports

Taking a daily multivitamin for two years helped older adults think a little better, especially with memory, and the improvement was about as much as what you'd normally see from being two years younger in terms of brain function.

Direct test
Why it supports

Taking a daily multivitamin for a few years helped older adults think and remember slightly better — like their brains were almost two years younger. The study found this effect was real and not just by chance.

Direct test
Why it supports

Taking a daily multivitamin didn't stop older adults from developing memory problems, but those who took it and still had memory issues declined much slower—like their brains aged two years less over the same time.

Direct test
Why it supports

Taking a daily multivitamin for two years helped older adults remember things a little better, and their overall thinking may have improved too. This suggests their brains aged a bit slower, though not necessarily by exactly two years as claimed.
