Going gray might happen because the stem cells that give rise to hair color cells get damaged over time, not because the color-making cells themselves stop working. Keeping these stem cells healthy...
Apple peel extract helps keep red blood cells looking healthy when they're stressed by mercury, but the flesh extract doesn't work as well at low doses.
Apple peel extract might help protect red blood cells from damage caused by mercury, reducing the release of tiny particles that could lead to blood clots.
Apple peel extract might help protect red blood cells from damage caused by mercury, better than the fruit's flesh does — and even a little bit goes a long way.
Apple peel extract from a type of Italian apple might help protect human red blood cells from damage caused by mercury, at least in lab tests.
Apple peel extract might help red blood cells recover from mercury damage by boosting their natural antioxidants.
Apple peel extract from a type of Italian apple might help protect red blood cells from damage caused by mercury, especially when used in higher amounts.
Using certain supplements like NMN or nicotinamide riboside might help older skin stay healthier by boosting cell energy, reducing damage, and increasing collagen — the stuff that keeps skin firm.
As skin cells get older, their energy factories don't get cleaned or replaced properly, which leads to cell damage, slower healing, and less collagen—making skin thinner and slower to repair.
When skin cells get old or are damaged by sun exposure, their energy factories (mitochondria) start to break down and leak bits that trigger the body’s alarm system, causing low-level, long-term...
As we get older, levels of a molecule called NAD+ in our skin go down, which slows down important repair processes and makes skin heal slower and break down over time.
As we get older and spend more time in the sun, our skin cells' energy factories (mitochondria) build up damage that can lead to wrinkles and less stretchy skin.
The pigment cells in your hair follicles can get damaged by normal sun exposure and the way they make color, especially as you get older, because their natural defenses weaken over time.
As we get older, the cells that give hair its color start to die off because of stress and lower levels of a protective protein, which is why hair turns gray and doesn’t grow back colored.
As we age, damage from oxidative stress can harm the cells that give hair its color, especially because the body’s natural antioxidants weaken over time — this leads to grey hair.
Blocking a protein called SIRT5 helps liver cells keep their energy and internal balance healthy when they're overwhelmed with fat.
If someone with fatty liver disease has a certain gene variant (SIRT5 G allele), their liver cells might show more activity in energy-producing parts, higher levels of damaging stress chemicals, and...
A certain gene change (SIRT5 rs12216101) might make it more likely for some Europeans with fatty liver disease to develop serious liver inflammation and scarring, even after accounting for other...
Taking L-methionine might help stop hair from going gray by protecting proteins in hair follicles, at least in lab tests.
When certain parts of a hair color enzyme get damaged by oxidation, it doesn't work as well, which can lead to hair gradually losing its color.
Gray hair might happen because certain repair proteins are missing in the hair roots, so damage from oxidation can't be fixed properly.
Gray and white hair naturally builds up hydrogen peroxide inside the hair shaft, kind of like rust forming, and that’s a sign the hair is under more chemical stress from the inside.
Hair turning white in mice with a certain gene problem isn't because pigment-making cells stop working — in fact, when scientists reduced that gene in pigment cells in a dish, they made *more* color,...
When a certain gene is turned off in mice, it damages the stem cells that give hair its color—but not the regular color-making cells—so the hair gradually loses pigment and turns gray or white.
