2 studiesWhy 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.

2 studiesExercise 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.
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.
