2Creatine Plus Lifting May Help Postmenopausal Women Keep Muscle and Strength
Looking at seven trials in postmenopausal women, creatine combined with resistance training added small but real gains in lean mass and leg strength. The sweet spot was at least 5 grams a day paired with lifting. Lower doses without exercise did nothing, and bone density didn't budge either way. Side effects were mild and matched placebo.
Losing Your Sense Of Smell May Signal Faster Muscle Decline With Age
In adults aged 71 to 82, those who had lost their sense of smell lost grip strength faster over seven years. Men with anosmia also lost more quadriceps strength, though women did not show the same leg muscle effect. The link suggests smell loss may be an early warning sign of neuromuscular aging.

2Why Standard Protein Advice May Fall Short for Older Adults
This review argues that general protein guidelines may not be enough for older adults trying to keep their muscle. Older bodies need more protein, spread evenly through the day, with a focus on leucine-rich foods like animal proteins. The authors note that creatine, vitamin D, collagen, and omega-3s, combined with resistance training, may further support muscle health.
Vitamin E Tocotrienols May Calm Oxidative Stress in Aging Muscle
In aging rats, a tocotrienol-rich form of vitamin E lowered oxidative damage and inflammation in muscle tissue, even though it didn't restore muscle mass. The supplement boosted natural antioxidant enzymes and protected DNA from age-related damage. The findings hint that this form of vitamin E may help support muscle health during aging, but human evidence is still needed.

4MRI Body Scans Predict Diabetes and Death Better Than BMI
Researchers used whole-body MRI scans from over 66,000 people to map fat and muscle in detail. High visceral fat more than doubled diabetes risk, while low muscle mass raised death risk by 44%. These measures predicted disease beyond what standard risk factors could catch. The team made their calculator free online.
Exercise Lowers One Key Inflammation Marker in Frail Seniors, But Not Others
Looking at dozens of trials in older adults with frailty or muscle loss, researchers checked whether exercise calmed chronic inflammation. Exercise meaningfully lowered TNF-alpha, an inflammatory protein linked to muscle wasting. But it did not budge two other common inflammation markers, IL-6 and CRP. So exercise helps with inflammation in frail seniors, but only partially.
When Your Body Ages Faster Than Your Birthday, Your Heart Pays the Price
In over 31,000 UK adults, those whose biological age outpaced their actual age had clearly worse heart outcomes. Each extra 4.6 years of biological aging meant a 29% higher risk of heart failure and a 16% higher risk of dying from heart disease. Heart scans showed these people also had weaker, smaller heart muscles. Women seemed more affected than men.
Why Losing Muscle With Age May Raise Your Cancer Risk
Healthy muscle releases tiny packets called extracellular vesicles that actually suppress tumor growth. As muscle shrinks with age (sarcopenia), it sends out fewer of these protective packets. In flies and mice, this helped tumors grow more easily. Exercise reactivated the pathway that produces these anti-tumor vesicles.

2Regular Exercise Cuts Death Risk Even in Older Adults With Muscle Loss
Older adults with sarcopenia (age-related muscle loss) or trouble with daily tasks faced a much higher risk of dying. But those who met the WHO's activity guidelines saw that risk drop sharply. The pattern held across studies in the US, Europe, and China.
Exercise Helps Older Adults With Sarcopenic Obesity, but Evidence Quality Is Mixed
Pooling 20 trials of older adults with sarcopenic obesity (low muscle plus excess fat), exercise reduced body fat, BMI, and LDL cholesterol while boosting muscle mass, grip strength, and walking speed. Resistance training stood out for building muscle and strength. Combined training (resistance plus cardio) improved the broadest range of outcomes. However, the authors caution that evidence quality was only moderate for body composition and low for metabolic benefits.
