This study found that limonin may promote hair growth by enhancing anagen signaling through autophagy activation in rat dermal papilla cells, suggesting its potential as a natural treatment for hair loss.

This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.

This study found that hair manganese levels did not vary by acute coronary syndrome or stable coronary artery disease severity, but a modest, non-significant correlation with body mass index suggests a potential link between manganese homeostasis and cardiometabolic status that warrants further investigation.

This study observed that while low vitamin D levels are associated with increased risk of autoimmune thyroid diseases, evidence from clinical trials on vitamin D supplementation shows inconsistent effects on thyroid function and disease progression, underscoring the need for further research.

This study identified specific gut bacterial pathways that may serve as potential therapeutic targets for managing androgenetic alopecia in obese individuals.

This study found that a combination of probiotic strains of Lactiplantibacillus administered over 16 weeks reduced the number and density of telogen hairs in individuals with androgenic alopecia, while increasing the abundance of Lactobacillus in their gut microbiota.

This study suggests that a complex of millet and wheat extract may enhance hair health by reducing oxidative stress and inflammation and potentially prolonging the anagen phase of hair growth in models.

This review discusses the vast potential uses of persimmon beyond its dietary benefits, including applications in sustainability and new product development, but reports no new clinical outcomes.

This article reviews evidence suggesting that vitamin D may help manage Hashimoto’s thyroiditis by affecting immune pathways and improving thyroid function, though more research is needed to fully understand its therapeutic potential.

This review summarizes existing reports on placenta extract for treating liver injury and discusses its mechanisms but provides no new clinical results.

This study investigated a novel extract from pomegranate byproducts, finding it effective in reducing blood pressure and inflammation in hypertensive rats, comparable to Captopril, while also highlighting the extract's potential to enhance the pomegranate supply chain and environmental benefits.

In this review, researchers highlighted that natural polyphenolics like flavonoids and resveratrol may help enhance testosterone production in aging males by boosting the expression of the Star gene in Leydig cells, potentially preventing age-related degenerative conditions linked to testosterone insufficiency.

In this study, Ishige sinicola extract was observed to improve bone density and structure in an animal model of estrogen deficiency-induced osteoporosis, suggesting its potential as a therapeutic option for postmenopausal osteoporosis by inhibiting osteoclast formation without cytotoxic effects.

This randomized controlled trial found that consuming *Gynostemma pentaphyllum* extract significantly improved hair elasticity, density, and diameter over 24 weeks without severe adverse events, suggesting it as a safe functional food ingredient for hair health improvement.

This review highlights the complex relationship between eating disorders and diabetes, indicating that individuals with diabetes may be at increased risk for eating disorders due to dietary and management demands, which can in turn affect blood sugar control.

In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.

In this study, saponins from Korean red ginseng were found to protect against the harmful effects of airborne particulate matter on human skin cells by reducing oxidative stress, inflammation, leptin expression, and melanin production.

This study found that women with polycystic ovary syndrome had deficient or suboptimal serum vitamin D levels, but the effects of vitamin D on metabolic syndrome and hormonal balance remain unclear.

This joint consensus statement from several Polish professional associations discusses strategies for improving obesity treatment and enhancing primary care's role in managing obesity, with no new empirical data reported.

This study in mice found that maternal iron deficiency led to hair loss and growth abnormalities in offspring due to increased oxidative stress and disrupted signaling pathways, but postnatal iron supplementation was able to reverse these effects.

This study found that enhancing quercetin bioavailability with EubioQuercetin significantly improved external aging signs in mice and influenced gut microbiota and intestinal gene expression, suggesting potential modulation through the gut microbiota–intestinal barrier axis.

This study found that adequate vitamin D status is necessary for metformin to effectively reduce prolactin levels in men with iatrogenic hyperprolactinemia, while improvements in glycemic control were observed across all vitamin D groups.

In this study, researchers found that specific genetic variations at loci rs1160312, rs6113491, and rs1041668 are independent risk factors for androgenetic alopecia in men, and these risks can be influenced by diet.

This study found that Gynostemma pentaphyllum leaf hydrodistillate (GPHD) promoted hair growth in mice similarly to minoxidil and upregulated growth factor expression via the AKT/β-catenin signaling pathway, with damulin B identified as an active component contributing to these effects.

This study found that a complex extract of Polygonatum sibiricum and Nelumbinis semen improved menopause symptoms in an ovariectomized rat model by enhancing blood lipid metabolism and reducing osteoporosis, without increasing risks of side effects like endometriosis, unlike conventional hormone-replacement therapy.

This research highlights selenium's critical roles in various biological processes and underscores the potential health impacts of both its deficiency and excess, including increased mortality risk, poor immune function, and neurological issues.

This study highlights the use of data mining techniques to identify malnutrition and nutritional deficiencies contributing to global health burdens, but it presents no new research findings.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

This review discusses the role of reactive oxygen species in regulating oscillating apoplastic pH gradients and growth in plant root hairs and pollen tubes, reporting no new experimental results.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.
