Can a Simple Blood Test Catch Liver Disease Early?

Yes. Researchers at Johns Hopkins developed an AI-powered blood test that detects early liver fibrosis and cirrhosis by analyzing patterns in tiny DNA fragments circulating in the blood. The test identified disease stages with high sensitivity across 1,576 patients, catching conditions that current blood tests miss entirely.

About 100 million Americans have liver conditions that put them at risk for serious damage. The problem is that current blood tests miss early fibrosis completely and only catch cirrhosis about half the time. By the time most people get a diagnosis, significant liver damage has already occurred.

Can Creatine Monohydrate Help Women Recover Faster from Exercise?

Yes, but it depends on timing. This randomized, double-blind study of 39 active women found that creatine monohydrate loading significantly improved fatigue resistance during the high hormone (luteal) phase of the menstrual cycle, with the creatine group showing a 5.8 percent improvement in fatigue index compared to essentially no change in the placebo group.

Creatine is one of the most studied supplements in sports science, yet the vast majority of that research has been done in men. Women’s bodies go through hormonal shifts each month that can affect exercise performance and recovery. During the luteal phase, when progesterone and estrogen are elevated, many women notice they feel more fatigued and their performance drops. This study set out to answer a practical question: can creatine monohydrate loading help women push through those hormone-related performance dips?

Is Creatine Supplementation Safe and Effective?

Yes. The International Society of Sports Nutrition (ISSN) reviewed the full body of research on creatine and concluded that it is safe and well-tolerated, even at doses up to 30 grams per day for as long as five years. Beyond athletic performance, creatine supplementation may also benefit brain health, injury recovery, and several clinical conditions.

Creatine is one of the most widely studied sports supplements in the world. It works by increasing the amount of creatine stored inside your muscles, which helps fuel short bursts of high-intensity exercise like sprinting or weightlifting. But this position stand from the ISSN goes well beyond the gym. The researchers gathered evidence showing that creatine may play a role in neuroprotection, rehabilitation, and even conditions like depression and neurodegenerative disease. What makes this review particularly valuable is the breadth of populations studied, ranging from infants to the elderly, from healthy athletes to patients with serious medical conditions.

Role of Creatine in the Heart: Health and Disease

Can Creatine Supplementation Help Your Heart?

Yes. This comprehensive review finds that creatine plays a key role in heart contraction and energy metabolism, and creatine supplementation may benefit patients with heart failure by improving specific heart function parameters and combating the muscle weakness that comes with the disease. The evidence also points to potential benefits in heart ischemia and protection against the heart-damaging side effects of certain chemotherapy drugs.

Most people know creatine as a supplement for building muscle in the gym. But creatine does far more than fuel bicep curls. Your heart is a muscle too, and it depends on creatine to keep beating with enough force to pump blood throughout your body. This review, published in Nutrients, examines decades of research on how creatine functions inside the heart, what happens when creatine levels drop during heart disease, and whether supplementing with creatine monohydrate can help.

Adderall and Heart Risk: What a Mayo Clinic Trial Found

Can a Single Dose of Adderall Affect Your Heart?

Yes. A Mayo Clinic randomized clinical trial found that a single 25 mg dose of Adderall caused significant spikes in blood pressure, heart rate, and stress hormones in healthy young adults who had never taken the drug before. Systolic blood pressure rose from 116 to 126 mm Hg, and the heart rate response upon standing doubled.

Adderall is one of the most commonly used prescription stimulants in the United States. It is approved for treating ADHD, but off-prescription use among college students and young professionals has grown sharply over the past decade. This Mayo Clinic trial set out to measure what actually happens to the cardiovascular system when someone who has never taken Adderall uses it for the first time, and the results raise real concerns.

Insomnia Plus Sleep Apnea Raises Heart Disease Risk Nearly 4-Fold

Can Insomnia and Sleep Apnea Together Cause Heart Disease?

Yes. A massive study of 937,598 U.S. veterans found that having both insomnia and obstructive sleep apnea, a combination called COMISA, was linked to a 3.8-fold increased risk of cardiovascular disease and a 2.4-fold increased risk of developing high blood pressure. These risks were far greater than having either sleep problem alone.

Most doctors treat insomnia and sleep apnea as separate problems. You might get a sleeping pill for one and a CPAP machine for the other. But this study from the Journal of the American Heart Association suggests that when these two conditions overlap, the danger to your heart jumps dramatically. The researchers are now calling for both conditions to be screened together as part of routine cardiovascular risk assessment.

Will Most Women in the U.S. Have Heart Disease by 2050?

Yes. A new American Heart Association scientific statement projects that nearly 6 in 10 U.S. women will have at least one type of cardiovascular disease by 2050. The driving forces are surging rates of high blood pressure, diabetes, and obesity, and the trends hit younger women and Black women the hardest.

This analysis draws on national health survey data from more than 30,000 participants. It paints a troubling picture of where women’s heart health is headed over the next 25 years. More than 62 million women in the U.S. already live with cardiovascular disease, and the numbers are expected to climb sharply. One in every three women will eventually die from it. Despite decades of awareness campaigns, the American Heart Association warns that current prevention efforts remain inadequate, especially for women of color and younger women.

Oats Lower Cholesterol Through Gut Bacteria, New Trial Finds

Can Oats Actually Lower Your Cholesterol?

Yes. A new randomized controlled trial found that eating oats for just two days lowered LDL cholesterol by about 10% in people with metabolic syndrome. The benefits were still visible six weeks later, and researchers finally uncovered why it works.

We have known for decades that oats are good for your heart. But scientists never fully understood the reason behind it. Most people assumed it was just the fiber. This new study from the University of Bonn reveals a surprising mechanism: your gut bacteria break down oats into special compounds called phenolic metabolites, and these compounds are what actually drive the cholesterol-lowering effect.

Can Limiting Sugar Early in Life Protect Your Heart Decades Later?

Yes. A study of over 61,000 people found that those who had their sugar intake restricted during the first 1,000 days of life had about 14% lower risk of heart failure and developed the condition roughly 2.6 years later than those who grew up without sugar restrictions.

Heart failure affects about 55.5 million people worldwide. It leads to poor quality of life, frequent hospital stays, and a higher chance of early death. We already know that drinking too many sugary beverages as adults raises heart failure risk. But what about sugar exposure at the very beginning of life? This study used a unique moment in history to find out.

Ultra-Processed Foods Linked to 47% Higher Heart Disease Risk

Do Ultra-Processed Foods Raise Your Risk of Heart Disease?

Yes. A study of nearly 4,800 U.S. adults found that people who ate the most ultra-processed foods had a 47% higher risk of heart attack or stroke compared to those who ate the least. This held true even after researchers accounted for age, sex, race, smoking, and income.

Ultra-processed foods are everywhere in modern diets. Sodas, packaged snacks, frozen meals, and processed meats fall into this category. On average, participants in this study got 26% of their total daily calories from these foods. That is roughly one out of every four calories coming from items that have been heavily changed from their original form, often loaded with added sugar, salt, unhealthy fats, and artificial ingredients.

Can Timing Your Last Meal Around Sleep Improve Heart and Metabolic Health?

Yes. A Northwestern Medicine study found that stopping eating at least three hours before bedtime and extending the overnight fast by about two hours lowered nighttime blood pressure by 3.5% and heart rate by 5%. The intervention also improved how the body handles blood sugar during the day.

This 7.5-week study included 39 overweight or obese adults aged 36 to 75. Researchers aligned the fasting window with each person’s natural sleep-wake cycle, a key factor in heart and metabolic health. Participants did not change how much they ate, only when they ate. The study was published February 12, 2026 in Arteriosclerosis, Thrombosis, and Vascular Biology (American Heart Association).

New Pill Cuts LDL Cholesterol by 57% in Major Trial

Can a Daily Pill Replace Cholesterol Injections?

Yes. In a phase 3 trial, a once-daily pill called enlicitide lowered LDL cholesterol by 57.1% at 24 weeks. That matches the results of injectable PCSK9 drugs that have been available for years, but in a simple pill you take by mouth.

For millions of people who struggle to control their cholesterol with statins alone, PCSK9 inhibitors have been a game-changer. The problem is that the current options, drugs like evolocumab (Repatha) and alirocumab (Praluent), require injections every two to four weeks. Many patients skip doses or avoid them entirely because of the needle. Enlicitide could change that by putting the same type of treatment into a daily pill.
