Always tired or struggling to stay motivated? That can sound an awful lot like chronic fatigue. New research points to a blood marker that may help explain why — and it’s one already linked to heart and brain health.

Beets and leafy greens already have a nitric oxide story featuring support for blood vessels and blood pressure. Now scientists have found a second pathway in the gut linked to even broader cardiometabolic health benefits.

Vitamin C was largely written off as a cancer treatment decades ago. Now scientists are revisiting the story — and one overlooked difference may explain why the question never really went away.

Orange juice may have more going for it than vitamin C. Researchers found that a daily glass changed activity in genes tied to inflammation, blood pressure and metabolism. That’s worth raising your glass.

You may buy “clean” shampoo, fragrance-free lotion or non-toxic cleaners to limit what comes into your body and your home. But lab testing of everyday products found far more chemicals than their labels revealed. Here’s what that means for making smarter choices.

For decades, you probably chose low-fat milk and yogurt to protect your weight and cholesterol. But when researchers had people eat three servings of full-fat dairy every day, what happened wasn’t what conventional wisdom would predict…

Body fat, belly fat and muscle are often top of mind when we think about diet and healthy aging. But a new study suggests your daily coffee habit may be influencing all three — along with your metabolism.

If you notice your knee crackling, it could signal osteoarthritis or a build-up of calcium crystals thought to only happen in really old age. Turns out they do structural damage much earlier than thought, especially if your mineral metabolism is off…

A Chinese medicinal herb has been shown to not only block bone loss, but encourage bone growth. That’s great news for anyone with osteoporosis. Even better, the active compound responsible for that phenomenal bone support is also found in coffee beans…

If you have hypothyroidism but still wake up exhausted, your thyroid may not be the only reason. Nearly half of people with low thyroid also had sleep apnea. That’s an overlap that can steal your deep sleep and raise heart risks.

Prostate cancer has a frustrating ability to shut out an immune attack, limiting the power of immunotherapy. But scientists found a way to change the tumor itself — and in early results, the combination made the tumors disappear.

Something starts changing in your brain’s memory center around 50. Scientists have uncovered a shift that may help explain why the aging brain becomes more vulnerable, and what steps we can take to protect it.

None of us want to add one more medication to a list that may already be long. So when a natural remedy, especially one with history, has the clout to improve cholesterol, that’s just too good to keep quiet about.

Think you’re eating everything your heart needs? Surprisingly most people fall short on a very important group of heart-protective plant compounds, even when meeting standard recommendations for fruit and vegetable intake.

Belly fat becomes increasingly common as we age. But researchers have discovered something that could make it far more dangerous: having too little of one important vitamin at the same time.

The American Heart Association has a running list on how to achieve optimal heart health. As a nation, we’ve got a lousy score. But an unexpected finding of adhering to this list doesn’t just mean a higher score… it can help you turn your age back as much as 6 years.

Three common midlife health risks may quietly chip away at your dementia-free years. Research suggests the difference could add up to nearly 13 years — and the good news is, these are risks you can do something about…

It’s one of the most predictable metabolic shifts of the menopausal transition: your cholesterol has been great all your life, then suddenly it’s not. But none of your doctors explained why. Here’s why losing estrogen pushes cholesterol up, and what you can do.

Most of us think heart attack risk comes down to clogged arteries. But a more immediate threat may be plaque that’s vulnerable to rupture. The good news? Several of the risks tied to dangerous plaque are ones you can change.

Calcified plaque deposits are a real problem when it comes to heart and brain health. But this harbinger of circulation problems doesn’t stop there. New researchs show how it steals your vision and the plan to beat it…

If caffeine gives your brain a jolt to get your morning started, might it also give your heart a jolt that could cause rhythm problems, like atrial fibrillation? That’s been the subject of debate. After following more than 300,000 coffee lovers for 4 years, there’s an answer…

Most people know CoQ10 helps produce the energy your heart needs. What’s less well known is what it does for your arteries — a second job just as important. Here’s why CoQ10 can matter twice as much for your cardiovascular health.

Buying supplements online couldn’t be easier. But counterfeit products, third-party sellers and hard-to-trace supply chains are reasons for caution. Here are five risks to know and five simple reasons going directly to the brand can offer greater peace of mind.

Your muscles don’t necessarily have to act their age. In fact, much of what we think of as muscle aging may not be inevitable. Discover what staying active does inside muscle cells, and how key nutrients can support the energy that powers them.

Belly fat can be stubborn — and the deeper fat carried around your middle is tied to serious health risks. But here’s encouraging news: Packing the right workout into just one day could be an effective way to shrink your waist and reduce body fat.

Coffee has been linked to liver health before. This time, however, researchers saw changes in blood proteins, alongside findings inside the liver itself, that make the connection much harder to dismiss…

That cool, smooth sensation from a vape may seem harmless. But researchers have discovered that some of the very chemicals added to make vaping feel less harsh can interfere with the heart’s electrical rhythm, especially when nicotine is part of the mix.

From longer life, to better brain, liver and metabolic health, coffee’s reputation as a healthy beverage keeps getting stronger. Now researchers may have uncovered one of the cellular mechanisms behind its benefits, and caffeine appears to be far from the most important player.

Your immune system can’t fight what it can’t see. Scientists say low levels of a common amino acid may make it harder for cells to display warning signals that alert immune defenders to viral and cancer threats. That’s just one of many reasons to support it…

Chronic pain can rob you of sleep — and poor sleep can make pain feel even worse. Researchers say a familiar bedtime supplement may have an unexpected advantage: It appears to target both sides of that vicious cycle.
