The protein that moves creatine in human cells has a specific 3D shape made of 12 spiral sections, and this shape helps it grab creatine and sodium like a lock and key.
Your heart can control how much sugar it uses during insulin activity, even if blood flow to the heart changes — meaning sugar use and blood flow might be controlled separately.
Taking nitroglycerin while insulin is active might lower how much sugar the heart uses, even if blood flow to the heart stays the same.
When the body can't make nitric oxide, blood flow to the heart drops, but the heart still takes in sugar normally when insulin is around — meaning nitric oxide isn't needed for insulin to help the...
In healthy middle-aged people, insulin helps the heart take in more sugar for fuel, but it doesn't make more blood flow to the heart. That means the heart can get more sugar without needing more...
If older adults who've had a certain kind of stroke take 20 grams of creatine every day for a week, their body shows signs that it's absorbing and using the supplement, based on a rise in a related...
Older adults getting better after a certain kind of stroke tend to gain strength and move better over three months, whether or not they take creatine — so most of the improvement probably comes from...
Older adults in the hospital for a certain kind of stroke can safely take a specific dose of creatine for a week — it’s generally well-tolerated, though some might get mild stomach issues or...
Taking 20 grams of creatine a day for a week after a certain kind of stroke might lower a brain-related protein linked to inflammation in older adults — suggesting it could help with brain healing.
Older adults who had a stroke didn’t get stronger or gain more muscle from taking creatine for a week, even if they ate enough protein and started moving early.
In young adults — whether they're lean, mildly overweight, or have well-controlled type 1 diabetes — men and women respond to insulin in similar ways in their muscles and blood flow when body size...
In young adults—even those with mild obesity or well-controlled type 1 diabetes—how blood flows in small muscle vessels and triglyceride levels help predict how well the body uses insulin to process...
In young adults who are lean, mildly overweight, or have well-controlled type 1 diabetes, things like BMI or fat levels don’t predict how well insulin improves blood flow in muscles—even though they...
In young adults, including those who are lean, mildly obese, or have well-controlled type 1 diabetes, fitness level (measured by oxygen use) is linked to how well their body handles sugar and blood...
In healthy young adults and those with mild obesity or well-controlled type 1 diabetes, how well their body uses insulin to process sugar is linked to how well insulin improves blood flow in their...
Taking magnesium with creatine might help endurance athletes get stronger muscle power, like how hard you can push or pull at your peak.
If you're an endurance athlete, taking magnesium-creatine might help your muscles hold more water, which could mean better creatine absorption and possibly help your muscles grow or recover faster.
In young, healthy guys recovering from intense workouts, taking creatine doesn’t seem to change muscle swelling or stress signals — which means the boost in muscle fuel recovery probably isn’t due to...
In young, healthy guys, creatine helps refill muscle energy after intense exercise, but it doesn’t work by making muscles more sensitive to insulin — that part hasn’t changed, according to tests and...
Creatine helps muscles refill their energy stores quickly after a tough workout, but this boost only lasts the first day — even if you keep taking creatine, it doesn’t keep speeding things up after...
If young, healthy guys take a lot of creatine with a high-carb diet after a tough workout, their muscles store more creatine within just a few days — and it keeps going up the longer they take it.
If young, healthy guys take 20 grams of creatine every day while eating a super high-carb diet after intense exercise, they rebuild their muscle fuel 82% faster in the first day compared to just...
Taking creatine for a week might change genes in young men's muscles that help reshape the muscle structure, possibly because the muscle cells are holding more water.
Taking creatine for a short time might turn on genes in young men's muscles that help fix DNA, possibly because the cells are reacting to the stress from holding more water.
