A trio of major studies found that finerenone may protect the kidneys and heart in far more people than previously thought. The drug significantly slowed kidney disease progression and reduced the risks of kidney failure, heart failure, cardiovascular death, and overall mortality. Researchers saw benefits not only in patients with diabetes but also in those with non-diabetic kidney disease, a group with limited treatment options.

A traditional Chinese medicinal root used for over a thousand years is attracting new scientific attention for its potential to combat hair loss. Studies suggest Polygonum multiflorum can block harmful hormones, activate hair-growth signals, protect follicles, and boost blood flow to the scalp. Researchers say the herb’s effects align remarkably well with both ancient descriptions and modern hair biology.

A large study found that women taking GLP-1 drugs, the medication class behind Ozempic, Wegovy, Mounjaro, and Zepbound, were about 30% less likely to develop breast cancer. Researchers say the findings are promising but not yet proof, and clinical trials are now being planned to test whether these drugs could help prevent breast cancer.

A major review of nearly 8,000 participants found that collagen supplements can improve skin health and ease osteoarthritis symptoms, especially when taken consistently over longer periods. 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.
