| ✦ New Frontier Of Your Mind ✦ A scoop goes in juice. Nineteen people with Alzheimer’s stirred creatine powder into a drink. Twenty grams a day, for eight weeks. Then a scanner found 11% more creatine in the tissue… Working memory came up too. The gym powder your brain runs on A muscle story that walked into the memory lab. // Quick Check First reaction? [🤯 Mind-blown](mailto:dex@primalcode.com?subject=Reaction:%20Mind-blown) [🔬 More like this](mailto:dex@primalcode.com?subject=Reaction:%20More) [🤷 Meh](mailto:dex@primalcode.com?subject=Reaction:%20Meh) Creatine is not exotic. You turn over 1 to 3 grams a day, and about half of that comes from food. Muscles hold most of it. The brain keeps a smaller store, and it draws on that store under load. Kostas Prokopidis and his team pooled eight trials of healthy people. Memory scores came out ahead of placebo. But the split by age is the part worth reading twice. // The Facts 0.88 effect on memory in adults aged 66 to 76\. That counts as large. 0.03 effect in people aged 11 to 31, which counts as nothing. 11% more creatine in the brain after 20 grams a day for eight weeks. Eight trials and 225 people in all, at moderate quality. The Alzheimer’s pilot ran 19 people with no control group. Creatine is linked to better memory in older adults, and it proves nothing about prevention.

Most supplement copy leans on one small trial. I spend more than $20,000 a year on private research… the sort hedge funds pay a fortune for. Walled off from the public. Then I read the paper behind the claim. Five grams a day has been in my own cupboard for two years. No memory gain I can feel, which is what the trials predict at my age… // The Fix A short night drains the store That is where one dose showed its hand. A German team gave 15 young adults 0.35 grams per kilo of body weight. Then they kept them awake. Word memory, processing speed and reaction time all held up better than placebo. The lift started around 3.5 hours in and ran to nine. That dose is enormous, though. For an 80 kilo man it lands near 28 grams. The authors call the right dose an open question. // The Fuel Three to five grams, every day // The Steps Creatine Monohydrate Plain monohydrate is the most studied form. 01 Take 3 to 5 grams a day. 02 Stir it into water, coffee or juice. Cold water needs a longer stir. 03 Timing hardly matters, but the daily habit does. 04 Bigger bodies may need 5 to 10 grams a day. 05 With kidney trouble, ask your doctor first.

Doses ran from 2.2 to 20 grams. Neither dose nor length shifted the result. A loading week is optional. Three grams a day fills the store over about four weeks instead. // Your Pick Where do you stand on creatine? Pick one and hit send.
