Vitamins like B12 and D can play an important role when levels are low, while protein may be one of the most overlooked nutrients for maintaining strength and independence. More isn’t always better, though—some supplements can cause harm or interact with medications.

Researchers also found modest benefits for muscle and tendon health. But the results challenge claims that collagen enhances sports performance, as it showed little effect on recovery or post-workout soreness.

Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis by up to four years, with benefits lasting long after treatment ended. Mon, 01 Jun 2026 09:25:47 EDT https://www.sciencedaily.com/releases/2026/05/260530053426.htm https://www.sciencedaily.com/releases/2026/05/260530004626.htm A new study suggests fish oil may help reduce insulin resistance even in people who aren't obese. In diabetic rats, omega-3 supplementation improved blood sugar levels, cholesterol, and inflammation by shifting immune cells into a more anti-inflammatory mode. Sun, 31 May 2026 01:15:13 EDT https://www.sciencedaily.com/releases/2026/05/260530004626.htm https://www.sciencedaily.com/releases/2026/05/260522031135.htm A surprisingly simple walking tweak may offer new hope for millions living with knee osteoarthritis. In a year-long clinical trial, researchers found that slightly changing the angle of a person’s foot while walking reduced knee pain as effectively as common medications — and even slowed cartilage damage inside the joint. Fri, 22 May 2026 07:07:58 EDT https://www.sciencedaily.com/releases/2026/05/260522031135.htm https://www.sciencedaily.com/releases/2026/05/260521072408.htm Researchers have discovered that the GLP-1 hormone targeted by drugs like Wegovy is present in very low amounts inside the joints of arthritis patients. That finding suggests high-dose GLP-1 medications could potentially reach the joints and influence inflammation directly, not just help through weight loss. Scientists say this could open the door to a completely new approach to arthritis treatment. Fri, 22 May 2026 02:12:43 EDT https://www.sciencedaily.com/releases/2026/05/260521072408.htm https://www.sciencedaily.com/releases/2026/05/260515233331.htm For years, “yo-yo dieting” has been blamed for wrecking metabolism and causing lasting damage, but a major new review says the fear may be wildly overblown. After analyzing decades of studies in humans and animals, researchers found little convincing evidence that losing weight and regaining it actually causes long-term harm. While regaining weight can erase some health improvements, it doesn’t appear to make people worse off than before. Sun, 17 May 2026 02:02:13 EDT https://www.sciencedaily.com/releases/2026/05/260515233331.htm https://www.sciencedaily.com/releases/2026/05/260515002146.htm Scientists are uncovering a surprising link between hidden tooth infections and blood sugar problems. Deep infections around tooth roots can create chronic inflammation that spreads through the body and may interfere with insulin function. Studies found that people who underwent root canal treatment often experienced better blood sugar control and reduced inflammation afterward. The research suggests that treating an infected tooth could have benefits far beyond the mouth. Fri, 15 May 2026 00:21:46 EDT https://www.sciencedaily.com/releases/2026/05/260515002146.htm https://www.sciencedaily.com/releases/2026/05/260508171123.htm Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced. Even more surprising, people and mice missing this protein don’t become obese as expected; instead, they lose fat tissue in a dangerous condition called lipodystrophy. Fri, 08 May 2026 17:21:20 EDT https://www.sciencedaily.com/releases/2026/05/260508171123.htm https://www.sciencedaily.com/releases/2026/05/260506225551.htm Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good. While biotin is often marketed for stronger hair and nails, there’s little evidence it actually helps cancer-related hair loss—and it can dangerously interfere with lab tests. Doctors say the supplement can distort key blood markers, potentially masking cancer recurrence or delaying treatment decisions. Thu, 07 May 2026 22:07:42 EDT https://www.sciencedaily.com/releases/2026/05/260506225551.htm https://www.sciencedaily.com/releases/2026/05/260505234603.htm A major 10-year clinical trial is turning one of the world’s most common knee surgeries on its head. Researchers found that trimming a damaged meniscus—a procedure long believed to relieve pain—offers no real benefit over placebo surgery. Even more surprising, patients who had the operation actually fared worse over time, with more symptoms, poorer function, faster progression of osteoarthritis, and a greater likelihood of needing additional surgery. Wed, 06 May 2026 01:54:27 EDT https://www.sciencedaily.com/releases/2026/05/260505234603.htm https://www.sciencedaily.com/releases/2026/05/260504211842.htm Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart attack damage and even showed promise for conditions like traumatic brain injury and pulmonary hypertension. Unlike earlier approaches that required direct injection into the heart, this new therapy can be delivered intravenously, allowing it to spread evenly and act quickly. Tue, 05 May 2026 14:20:47 EDT https://www.sciencedaily.com/releases/2026/05/260504211842.htm https://www.sciencedaily.com/releases/2026/04/260430032411.htm A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis. Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic workouts. The findings also confirm that exercise is a safe and essential part of treatment. Thu, 30 Apr 2026 03:30:17 EDT https://www.sciencedaily.com/releases/2026/04/260430032411.htm https://www.sciencedaily.com/releases/2026/04/260426012305.htm Mixing up your workouts might be the real secret to a longer life. Long-term research tracking over 100,000 people for more than three decades suggests that doing a variety of physical activities—rather than just more of the same—can significantly lower the risk of death. Interestingly, the benefits don’t keep rising endlessly; they seem to level off after a certain point, hinting at a “sweet spot” of activity. Mon, 27 Apr 2026 01:32:16 EDT https://www.sciencedaily.com/releases/2026/04/260426012305.htm https://www.sciencedaily.com/releases/2026/04/260426012303.htm Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline. Sun, 26 Apr 2026 01:57:51 EDT https://www.sciencedaily.com/releases/2026/04/260426012303.htm https://www.sciencedaily.com/releases/2026/04/260422091043.htm Scientists at UC Irvine have found a way to potentially reverse age-related vision loss by targeting the ELOVL2 “aging gene” and restoring vital fatty acids in the retina. Their experiments in mice show that supplementing with specific polyunsaturated fatty acids—not just DHA—can restore visual function and even reverse cellular aging signs. Wed, 22 Apr 2026 21:06:41 EDT https://www.sciencedaily.com/releases/2026/04/260422091043.htm https://www.sciencedaily.com/releases/2026/04/260414075646.htm A major new study reveals that treating gout may do far more than ease painful joint flare-ups—it could also protect the heart. Researchers found that patients who took common gout medications like allopurinol and successfully lowered their blood urate levels had a significantly reduced risk of heart attacks, strokes, and cardiovascular death over five years. Tue, 14 Apr 2026 23:11:38 EDT https://www.sciencedaily.com/releases/2026/04/260414075646.htm https://www.sciencedaily.com/releases/2026/04/260413043129.htm New research reveals that obesity affects men and women in surprisingly different ways. Men are more likely to develop harmful abdominal fat and signs of liver stress, while women show higher inflammation and cholesterol levels. These differences could help explain why health risks vary between sexes. Scientists say this could lead to more tailored treatments for obesity. Mon, 13 Apr 2026 09:29:20 EDT https://www.sciencedaily.com/releases/2026/04/260413043129.htm https://www.sciencedaily.com/releases/2026/04/260411022023.htm Putting on weight earlier in life may be more dangerous than previously thought. Researchers found that early adulthood obesity significantly raises the risk of premature death, especially from major diseases like heart disease and diabetes. The longer the body carries excess weight, the greater the damage appears to be. Interestingly, cancer risk in women didn’t follow this pattern, suggesting other biological factors are at play. Sat, 11 Apr 2026 09:54:18 EDT https://www.sciencedaily.com/releases/2026/04/260411022023.htm https://www.sciencedaily.com/releases/2026/04/260406080131.htm Scientists have identified a little-known receptor, GPR133, as a powerful regulator of bone strength. By activating it with a newly discovered compound called AP503, they were able to boost bone density in mice and counteract osteoporosis-like damage. The finding opens the door to a new kind of treatment that could not only prevent bone loss but also rebuild weakened bones, offering fresh hope for millions affected by osteoporosis, especially aging populations. Mon, 06 Apr 2026 08:14:33 EDT https://www.sciencedaily.com/releases/2026/04/260406080131.htm https://www.sciencedaily.com/releases/2026/04/260402000229.htm A new study suggests that one of the most widely used health metrics, BMI, may be getting it wrong for a large portion of the population. By comparing BMI classifications with precise body fat measurements using advanced DXA scans, researchers found that more than one-third of adults were placed in incorrect weight categories. Many people labeled as overweight or obese did not actually have the corresponding body fat levels, while others were missed entirely. Fri, 03 Apr 2026 00:19:13 EDT https://www.sciencedaily.com/releases/2026/04/260402000229.htm https://www.sciencedaily.com/releases/2026/03/260330084511.htm A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also avoid the risks tied to common medications. The findings suggest that low-cost, accessible therapies could play a bigger role in how doctors treat arthritis in the future.

A 10-year study in Japan found that seniors who rode bicycles had lower risks of needing long-term care and dying—especially those who didn’t drive. Continuing or even starting cycling later in life still delivered noticeable benefits. The results highlight biking as a surprisingly powerful tool for maintaining independence and well-being. Wed, 18 Mar 2026 18:01:48 EDT https://www.sciencedaily.com/releases/2026/03/260318033100.htm https://www.sciencedaily.com/releases/2026/03/260308201618.htm Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16–30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge doses of caffeine and stimulants that can linger for hours. Researchers say the findings raise concerns about the impact on young people’s health and development. Mon, 09 Mar 2026 17:02:26 EDT https://www.sciencedaily.com/releases/2026/03/260308201618.htm https://www.sciencedaily.com/releases/2026/03/260307213228.htm A Yale study found that lowering parent stress can help protect young children from obesity. When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and exercise. Sun, 08 Mar 2026 20:28:48 EDT https://www.sciencedaily.com/releases/2026/03/260307213228.htm https://www.sciencedaily.com/releases/2026/03/260305223231.htm Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the body’s own repair process. In animal studies, it helped regenerate bone without triggering strong immune reactions. The team now plans to scale up production and begin testing the approach in humans.

Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage. Wed, 04 Mar 2026 16:35:02 EST https://www.sciencedaily.com/releases/2026/03/260303145725.htm https://www.sciencedaily.com/releases/2026/02/260225081208.htm A sweeping new analysis of the evidence suggests that exercise therapy — long promoted as a first-line treatment for osteoarthritis — may offer only small and short-lived relief, and in some cases might be no better than doing nothing at all. After reviewing dozens of clinical trials involving more than 13,000 participants, researchers found that benefits for knee osteoarthritis pain were minimal and tended to shrink in larger or longer-term studies. Wed, 25 Feb 2026 23:43:58 EST https://www.sciencedaily.com/releases/2026/02/260225081208.htm https://www.sciencedaily.com/releases/2026/02/260225081142.htm A gel-like sugar coating on immune cells has been found to play a starring role in psoriasis. Researchers discovered that immune cells shed this outer layer to help them exit the bloodstream and enter inflamed skin. This challenges the long-held idea that only blood vessel walls changed during this process. The finding could help guide new therapies aimed at controlling harmful inflammation. Wed, 25 Feb 2026 08:11:42 EST https://www.sciencedaily.com/releases/2026/02/260225081142.htm https://www.sciencedaily.com/releases/2026/02/260219040816.htm A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and lowered harmful inflammatory cells. The discovery could pave the way for safer treatments for arthritis, heart disease, and other inflammation-related conditions.

Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially DHA. The results suggest that not all supplements work the same way, and genetics could determine who truly benefits. Fri, 13 Feb 2026 09:20:25 EST https://www.sciencedaily.com/releases/2026/02/260212234216.htm https://www.sciencedaily.com/releases/2026/02/260212025618.htm A protein called HIF1 may be the missing link behind painful tendon injuries like jumper’s knee and tennis elbow. Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, turning the protein off protected tendons — even under heavy strain.

Researchers found that time-restricted feeding, a form of intermittent fasting that limits meals to an 8-hour daily window, reduced disease activity by 40% and cut abdominal discomfort in half over 12 weeks. Participants also lost weight and showed healthier inflammation and immune markers, even though they did not reduce calories or change what they ate.

This “synbiotic” combination outperformed omega-3 supplements and fiber alone, leading to the broadest drop in inflammation-related proteins in healthy adults. By feeding beneficial microbes and helping them produce compounds like butyrate, the combo appeared to improve overall immune balance and metabolic health.

Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference lies in the joint’s ability to keep those cells in check. This insight could help doctors identify warning signs early and prevent lasting joint damage.

New research suggests people taking these medications may not be getting enough guidance on protein, vitamins, and overall diet quality, increasing the risk of muscle loss and nutrient deficiencies. Wed, 04 Feb 2026 10:43:08 EST https://www.sciencedaily.com/releases/2026/02/260203030551.htm https://www.sciencedaily.com/releases/2026/01/260129080443.htm Collagen pills sound like a shortcut to younger skin, but solid evidence doesn’t back them up. Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead.

Instead of attacking cancer cells head-on, the experimental immunotherapy targets macrophages—immune cells that tumors hijack to shield themselves from attack. By eliminating or reprogramming these “bodyguards,” the treatment cracks open the tumor’s protective barrier and allows the immune system to flood in and destroy the cancer. Fri, 30 Jan 2026 01:05:29 EST https://www.sciencedaily.com/releases/2026/01/260128075332.htm https://www.sciencedaily.com/releases/2026/01/260127010149.htm Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active.

Scientists found that colon tissue in younger patients was stiffer, even in areas that appeared healthy, suggesting these changes may happen before cancer develops. Lab experiments showed that cancer cells grow faster in rigid environments.

Most clips focus on diet changes and supplements, while barely mentioning the long-term treatments doctors say are essential for controlling the disease. Many videos also frame gout as a lifestyle problem, rather than a condition driven largely by genetics and underlying health factors. Researchers say the platform has huge potential—but only if accurate medical voices step in.

Researchers now link symptoms to lingering virus, inflammation, micro-clots, and disrupted energy metabolism. While structured rehab and pacing can improve quality of life, a growing list of experimental treatments—from antivirals and metformin to microbiome therapies and biologics—shows early promise. Clear answers, however, are still limited by small studies and the lack of large, definitive trials.

Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like they were working more. Their muscles and hearts worked overtime, but their sense of strain stayed the same. This brain-body mismatch could one day help make exercise feel less intimidating, especially for people who struggle to stay active. Thu, 08 Jan 2026 02:13:42 EST https://www.sciencedaily.com/releases/2026/01/260107225519.htm https://www.sciencedaily.com/releases/2026/01/260106224639.htm Bariatric surgery far outperformed GLP-1 weight loss drugs in a new real-world comparison of more than 50,000 patients. Two years after treatment, surgery patients lost about 58 pounds on average, while those using semaglutide or tirzepatide lost roughly 12 pounds. Even patients who stayed on GLP-1 drugs for a full year saw much smaller results than surgical patients. High dropout rates and real-world challenges appear to blunt the drugs’ effectiveness.

Strict NHS criteria mean only a limited number of patients will receive Mounjaro, while many others must pay privately. Researchers say this risks worsening existing health inequalities, especially for groups whose conditions are often missed or under-diagnosed. They are calling for fairer, more inclusive access before gaps in care widen further.

The change comes from adding waist and body fat measurements to BMI, capturing people who were previously considered healthy. Many of these newly included individuals face higher risks of diabetes and heart disease. The findings suggest that where fat is stored may be just as important as overall weight.

Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimer’s biomarkers. The results offer fresh hope that recovery may be possible.

From misconceptions about heavy lifting and bed rest to confusion over posture, exercise, and surgery, Dr. Meghan Murphy breaks down what really causes pain and what actually helps. Her insights reveal that everyday habits, movement, and smart prevention often make a bigger difference than people realize.

Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression.

Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the brain’s reward hub.

Researchers emphasize the critical role of EPA and DHA across all life stages and point out that food alone often can’t meet needs. The review calls for clearer global guidelines and easier access to sustainable omega-3 sources. It also highlights the challenges different populations face in reaching healthy intake levels.

The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low choline levels appeared closely tied to these changes. The results hint that early metabolic disruptions may quietly influence the brain long before symptoms emerge.

By studying people with RA-linked antibodies over seven years, researchers discovered sweeping inflammation, malfunctioning immune cells, and even epigenetic reprogramming in cells that had never encountered a threat. These changes show that the body is preparing for autoimmune attack long before joints become damaged.

The procedure creates a hybrid immune system that stops autoimmune attacks and eliminates the need for immune-suppressing drugs. The method uses tools already common in clinical practice, putting human trials within reach. Scientists think the same strategy could transform treatments for autoimmune conditions and organ transplantation.
