In rat brain tumor cells, a substance called cyclocreatine gets pulled in using energy and sodium, but when sugar levels drop, this process slows down a lot—showing it needs energy from sugar to work...
When scientists gave a substance called cyclocreatine to two types of cancer cells, one kind (from rat brain tumors) stored a modified version of it, but the other kind (from human ovarian tumors)...
Cyclocreatine slows down the growth of certain cancer cells in a lab dish, but it doesn’t harm their outer layer or energy supply — so it probably works in a different way.
When guys who lift weights gain muscle, their muscle cells also hold more water — and this happens whether or not they take creatine. It suggests that growing muscle might be linked to how much water...
If you're a guy who lifts weights, taking creatine won't make you hold more water outside your cells compared to just training — the water increase seems to come from working out, not the supplement.
If you're a guy who lifts weights, taking creatine might help you gain more muscle and hold onto more water inside your cells than just training alone.
If you're a guy who lifts weights, taking creatine for 8 weeks can help you gain muscle and hold more water inside your muscle cells — but the water doesn't increase more than the muscle does, so...
Taking creatine every day for two weeks doesn’t change how much water is in or around your cells — even though the balance between them might shift a little — at least in young women who work out...
Taking a fake supplement (like sugar powder) for two weeks doesn’t change body water balance in young female athletes, so if real creatine does change it, the effect is likely from creatine itself.
Taking creatine for two weeks — whether a little or a lot — doesn’t change weight or body composition in young women who work out regularly.
Taking 5 grams of creatine every day for two weeks doesn’t seem to change how water is distributed in the body for young women who work out regularly.
Taking 20 grams of creatine every day for two weeks might help young active women hold more water inside their cells, which could support muscle function.
If you're on dialysis, taking 5 grams of creatine every day for a year might add about three-quarters of a liter of water inside your cells, which could help you gain lean body mass.
Taking creatine every day for a year doesn’t help improve nutrition or reduce inflammation in people on dialysis, according to this claim.
If you're on dialysis, taking a creatine supplement every day for a year might help your muscles hold more water and get bigger, and most people in the study saw some benefit.
Taking a creatine supplement every day might help kidney dialysis patients gain more muscle and fight muscle loss over time.
Taking a creatine supplement every day might help kidney patients on dialysis keep more muscle mass over time.
Insulin and exercise help muscles take in a type of amino acid even without using the cell's usual sodium-potassium pump, suggesting they use a different route to get nutrients in.
When muscles are resting, they need a specific cellular pump to bring in a type of nutrient, but when they're active—like during exercise or after insulin kicks in—they use a totally different method...
Giving healthy adults normal levels of certain hormones like GLP-1 and insulin — either alone or together — doesn't change how stiff their main artery is over about two and a half hours.
When healthy adults get infusions of two hormones—GLP-1 or insulin—each one widens a major arm artery and boosts blood flow by about 30%. But when both are given together, they don’t widen the artery...
When healthy adults get both GLP-1 and insulin at the same time, it doesn’t boost blood flow to their heart or muscles any more than using just one of the hormones alone.
When healthy adults get a controlled dose of insulin for two hours, it boosts blood flow and blood volume in their heart and muscle tissues, helping more nutrients move between blood and muscles.
When healthy adults get a specific dose of a hormone called GLP-1 through an IV, it quickly boosts blood flow in the small vessels of their heart and muscles, helping deliver more nutrients and...
