Higher vitamin D levels linked with improved marker of biologic aging

February 27 2026. A meta-analysis published February 6, 2026, in Medicine revealed an association between higher levels of vitamin D and longer telomeres: bits of genetic material that cap and protect the ends of chromosomes and shorten during cellular aging. Rapid telomere shortening has been associated with such aging-related diseases as cardiovascular disease and diabetes, as well as decreased lifespan.

"Optimal vitamin D levels could protect against telomere shortening through various mechanisms, including its anti-inflammatory effects, reduction of oxidative stress, improvement of telomerase activity, regulation of cellular differentiation, proliferation, and apoptosis, as well as promotion of genomic stability," Jie Shen and colleagues wrote.

The researchers analyzed data from 21 studies that ascertained serum 25-hydroxyvitamin D levels and leukocyte (white blood cell) telomere length among a total of 185,191 participants. They found a significant association between serum vitamin D levelsand telomere lengthin adults, women and individuals with deficient levels of the vitamin. Shen and colleagues noted that men usually have shorter telomeres compared with women, which could explain a lack of a significant association between telomere length and vitamin D in men observed in the current meta-analysis. Estrogen, which is higher in women than in men, can stimulate the production of telomerase, an enzyme that maintains telomere length, and estrogen also has a protective antioxidant effect.

"This meta-analysis highlights a positive association between serum 25-hydroxyvitamin D levels and leukocyte telomere length in specific subgroups, including women, adults, and individuals with vitamin D deficiency," the authors concluded. "These findings suggest that vitamin D may play a role in maintaining telomere length in these populations. However, no significant associations were observed in men, children, or individuals with sufficient vitamin D levels, indicating that the relationship between vitamin D and leukocyte telomere length may vary based on demographic and health factors."

Vitamin D intake associated with improvement in metabolic syndrome symptoms

February 25 2026. A systematic review and meta-analysis found improvement in obesity-associated metabolic syndrome in men and women who consumed vitamin D3 or active vitamin D in comparison with no treatment, a placebo or low-dose vitamin D. The findings were reported February 20, 2026, in the journal Medicine.

The meta-analysis included 50 randomized, controlled trials that evaluated the effects of vitamin D2, vitamin D3 or active vitamin D (calcitriol) consumed for eight weeks or longer in participants with obesity and/or metabolic syndrome. Metabolic syndrome is a cluster of factors that increase the risk of developing type 2 diabetes and/or cardiovascular disease. Authors Qin Huang and colleagues at The Hospital of Huazhong University of Science and Technology noted that obesity-associated metabolic syndrome is characterized by increased abdominal fat, insulin resistance and abnormal blood lipids (cholesterol and triglycerides).

Meta-analysis of the trial data determined that participants who were given vitamin D3 or active vitamin D had a lower risk of abdominal fat that was not observed among individuals who received vitamin D2. Vitamin D3 and active vitamin D also improved fasting glucose and insulin resistance, as well as reduced low-density lipoprotein (LDL) cholesterol which, when elevated, is associated with an increased risk of cardiovascular disease. Higher doses of at least 2,000 IU (50 mcg) vitamin D were found to be significantly more effective than lower doses, and longer treatment periods of six months or more were significantly more effective than short-term treatment.

"In obesity-associated metabolic syndrome, vitamin D3 and active vitamin D, particularly at higher doses and longer durations, are associated with reductions in visceral fat and improvements in glycemic control, insulin resistance, and selected lipid indices," Huang and colleagues concluded. "The effect of vitamin D2 was more limited, especially in the improvement of glucose-lipid metabolism."

Higher vitamin D, testosterone linked with lower BMI, better sexual function in men

February 23 2026. A study involving more than two thousand visitors to a men's medical clinic found an association between higher serum vitamin D levels and lower body mass index (BMI) and male symptoms of aging. Similar benefits were observed in association with higher serum testosterone concentrations. The findings were reported February 13, 2026, in The Aging Male medical journal.

The study included 2,059 men with symptoms of low testosterone. Blood samples were analyzed for serum vitamin D, testosterone and other factors. Participants completed Aging Males' Symptoms and International Index of Erectile Function-Erectile Function (IIEF-EF) subdomain questionnaires. High Aging Males' Symptoms questionnaire scores and low IIEF-EF questionnaire scores indicated more severe symptoms.

Participants' vitamin D and testosterone levels were predominantly suboptimal, and nearly half of the men had a BMI that categorized them as overweight. Average vitamin D levels were higher in men who did not have hypogonadism (low testosterone associated with symptoms) in comparison with men who had the condition. Both higher serum vitamin D and testosterone were associated with lower Aging Male Symptoms scores and BMI, and higher scores in the erectile function domain of the IIEF.

Authors Karim S Haider and Michael Zitzmanm noted that a bidirectional relationship between vitamin D and testosterone may exist in which the vitamin effects testosterone production via vitamin D receptors, while testosterone influences vitamin D activation and metabolism. "These interactions, although largely associative rather than causative, may hold important implications for sexual health and systemic well-being," they wrote. "Some studies already suggested that treatment via administration of testosterone to hypogonadal men increased their vitamin D levels."

‘Albeit causality cannot be inferred, this analysis highlights a clinical convergence of vitamin D and testosterone in modulating sexual health and quality of life in men," they concluded.

Extra virgin olive oil consumption linked with healthy aging

February 20 2026. A study reported February 12, 2026, in the European Journal of Nutrition revealed an association between greater intake of extra virgin olive oil and better physical health-related quality of life in active older adults.

"The physical component of health-related quality of life, which includes physical function, physical role, bodily pain and general health status, tends to decline with age due to muscle loss and body composition changes, making it more difficult to perform activities of daily living," authors Javier Conde-Pipó and colleagues wrote. "Dietary habits play a crucial role in health-related quality of life, as nutrition directly impacts physical and mental health."

The investigation included 180 physically active individuals aged 41–80 years who adhered to a Mediterranean diet, which is characterized by a high intake of vegetables, fruit, cereals, nuts, legumes and olive oil, moderate consumption of fish, meat, dairy products and red wine, and a limited intake of eggs and sweets. High extra virgin olive oil consumption was defined as four tablespoons per day or more and low consumption was categorized as less than four tablespoons per day. Questionnaire responses provided information that was used to determine health-related quality of life.

In people with higher extra virgin olive consumption, there was no significant association between aging and decline in physical health-related quality of life. However, men and women with low extra virgin olive oil intake showed lower health-related quality of life with aging and an increase in bodily pain with age.

"This study provides novel evidence suggesting that higher extra virgin olive oil consumption is associated with the preservation of physical function and reduced pain perception in aging," the authors concluded. "Promoting regular extra virgin olive oil consumption within the Mediterranean diet could represent a simple and sustainable public health strategy to support healthy aging, aligning with current efforts to extend both life expectancy and years lived in good health and functional independence."

Meta-analysis affirms benefits of herbs for ED

February 18 2026. A systematic review and meta-analysis concluded that the herbs ginseng and saffron significantly enhanced erectile function and other aspects of sexual function in men affected by erectile dysfunction (ED). The findings were reported in the January 2026 issue of the Journal of Traditional and Complementary Medicine.

“Current strategies for managing ED revolve primarily around pharmacotherapy, with the primary drug being phosphodiesterase type 5 (PDE5) inhibitors,” authors Chao-Yen Ho and colleagues in Taiwan wrote. “Interest in herbal dietary supplements as potential safe and effective alternatives to conventional drugs for treating ED has been growing.”

For the meta-analysis, the researchers identified 14 randomized, controlled trials that included a total of 1,227 men with ED. Trials evaluated the effects of single herbs or herb combinations on erectile function and associated factors.

Compared with the control groups who received a placebo or no treatment, men who received herbal treatment experienced positive effects in erectile and orgasmic functions, sexual desire, subjective intercourse satisfaction, overall satisfaction and serum testosterone. When individual herbs were evaluated, ginseng improved all the outcomes except subjective intercourse satisfaction and saffron improved all but overall satisfaction and testosterone levels.

As mechanisms, ginseng was noted to promote the release of nitric oxide, which enhances blood flow during arousal. Ginseng may enhance vascular health via its antioxidant property and may also support healthy testosterone levels and libido. Saffron enhances nitric oxide production and has an antioxidant property that helps maintain vascular health.

“Herbal dietary supplements demonstrate generally favorable effects across multiple outcomes related to ED, with the most robust and consistent evidence observed for saffron and ginseng,” Ho and associates concluded. “With the advancement of methodologically rigorous research, standardized product formulations, and comprehensive evaluations of safety and cost-effectiveness, herbal interventions could be more confidently incorporated into evidence-based management frameworks for ED.”

Luteolin, astragalus compound could help spinal cord injury patients

February 16 2026. The March 2026 issue of the journal Precision Clinical Medicine uncovered a role for known plant compounds in spinal cord regeneration following injury.

Researchers in China evaluated the effects of luteolin, a flavonoid that supports cellular health and healthy aging, and astragaloside IV, which occurs in the herb astragalus and is used in Chinese medicine, in rat cells exposed to oxidative stress. While each compound alone offered limited protection against oxidative stress, combining the plant compounds decreased the accumulation of reactive oxygen species and boosted cell survival.

In rats in which spinal cord injury was induced, treatment with luteolin plus astragaloside IV aided in the recovery of motor functions and lowered reactive oxygen species that cause oxidative stress compared with untreated rats. Injured spinal cords showed signs of improvement, including smaller lesion areas and improved structural integrity. Neuroinflammation and other contributors to the damage that results from spinal cord injury were also lower in treated animals.

“The luteolin-astragalus combination represents a paradigm shift in spinal cord therapy, merging traditional Chinese medicine's multi-target philosophy with modern precision medicine,” one of the report’s senior authors commented. “What makes this strategy compelling is the way these two compounds complement each other—one strongly counteracts oxidative stress, while the other supports neural protection and regeneration. By working together, they create conditions that are far more favorable for repair. This study provides a strong rationale for exploring synergistic, multi-component therapies in the treatment of complex neurological injuries.”

“Our study provides compelling evidence for the multi-target therapeutic effects of the luteolin-astragaloside combination in promoting neural repair and functional recovery after spinal cord injury,” the authors concluded.

Another way of looking at aging

February 13 2026. An upcoming conference will bring together researchers who question prevailing approaches to aging that view its cause as a single defect. Instead, aging may be a loss of coordination between biological systems.

The 2nd World Congress on targeting Longevity, to be held April 8-9, 2026, in Berlin, was organized by the World Mitochondria Society and the International Society of Microbiota. The meeting's objective is to explore the effects of systems on longevity rather than single mechanisms. "Longevity is often approached as a problem to solve," World Mitochondria Society founder and meeting organizer Marvin Edeas, MD, PhD, remarked. "But aging behaves more like a loss of coordination between systems, metabolism, immunity, mitochondria, and microbial ecosystems. Understanding that dialogue may be more important than targeting individual pathways."

As examples of systems coordination, it is now understood that mitochondrial signaling influences inflammation in senescent states, interactions between microbes and the brain influence predict aging trajectories and tissue repair is regulated by metabolic environments.

When asked about the next breakthrough in longevity science, Dr Edeas emphasized an understanding of biologic resilience, which is how biologic systems remain coordinated. The meeting's organizing committee is interested in innovations that are more than single target approaches, focus on prevention rather than correction, integrate data, biology and "real world" use, and more. "This congress is not about repeating established narratives," Dr Edeas wrote. "It is about stepping outside familiar models to better understand aging as a dynamic, interconnected biological process."

"The future of longevity might not lie in doing more of the same but in perceiving the system differently."

Meta-analysis affirms cardiometabolic benefits of garlic

February 11 2026. A systematic review and meta-analysis of clinical trials published in the January 2026 issue of Nutrition Reviews concluded that garlic consumption supports healthy cardiovascular risk factors and inflammatory biomarkers in men and women.

"Allium sativum, known as garlic, is a commonly used herb for enhancing flavors and has been historically employed as a form of traditional medicine, particularly within regions of Asia," Vahideh Behrouz, PhD, of Kerman University of Medical Sciences and colleagues wrote. "Various garlic products, such as garlic tablet, aged garlic extract (AGE), garlic powder, garlic oil, black garlic, and raw garlic are commercially accessible and have demonstrated efficacy in diminishing mortality rates and cardiovascular risk."

The research team identified 108 randomized, controlled trials that included a total of 7,137 adults for the meta-analysis. Trials evaluated cardiometabolic effects of different forms of garlic and the garlic compound allicin on metabolic and cardiovascular blood markers. Fourteen trials involved healthy participants while the remainder included participants who had metabolic or other conditions.

Compared with control group participants, the meta-analysis showed that men and women who received garlic had significantly improved serum triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL), low-density lipoprotein (LDL) cholesterol, fasting blood glucose, insulin, insulin resistance, systolic blood pressure, diastolic blood pressure, aspartate aminotransferase (AST, an enzyme that occurs in liver, heart, kidneys and muscle), C-reactive protein (CRP, a marker of inflammation), tumor necrosis factor-alpha (a proinflammatory protein), total antioxidant capacity, and malondialdehyde (a marker of oxidative stress). Garlic did not affect weight or body mass index.

"This meta-analysis demonstrates that garlic intake significantly improves key cardiovascular risk markers, including lipid profiles, glycemic indices, blood pressure, oxidative stress, and inflammatory biomarkers, particularly in adults with unfavorable baseline risk factors," Dr Behrouz and associates concluded. "These findings suggest that garlic may enhance cardiovascular health in high-risk populations."

Large study finds 38% of cancers preventable

February 06 2026. In a study published February 3, 2026, in Nature Medicine, researchers estimated that 38% of cancers worldwide are preventable. Not surprisingly, smoking was revealed to be the leading contributor to preventable cancers, followed by infections and alcohol consumption. Avoidance of these risk factors is "one of the most powerful ways that we can potentially reduce the future cancer burden," first author Hanna Fink of the World Health Organization commented.

Among 18.7 million new cancer cases that occurred in 2022, which included 36 cancer types in 185 countries, 7.1 million were attributable to 30 modifiable factors, including tobacco smoking, alcohol consumption, high body mass index, insufficient physical activity, smokeless tobacco and areca nut, insufficient breastfeeding, air pollution, ultraviolet radiation, 13 occupational exposures and nine infectious agents (particularly human papilloma virus which causes cervical cancer). Lung, cervical and stomach cancers made up nearly half of preventable cancers.

For men, 4.3 million new cancer cases were determined to be preventable and among women, the figure was 2.7 million. Smoking was the leading preventable cancer risk factor for men and infections were the leading risk factor for women.

"In summary, nearly 4 in 10 cancer cases worldwide in 2022 could have been prevented by eliminating exposure to the risk factors considered in this study," Fink and colleagues concluded. "Our results reinforce the call for effective cancer prevention, which requires sustained political commitment and investment tailored to the specific risks of populations worldwide."

Fink encourages the current study's findings to be utilized for cancer prevention strategies based on the strongest risk factors for men and women in various regions. "It's not a one-size-fits-all approach," she noted.

Ubiquinol improves insulin sensitivity in prediabetic adults

February 04 2026. A randomized, double-blind, placebo-controlled pilot study that evaluated the effects of the ubiquinol form of coenzyme Q10 (CoQ10) in men and women with prediabetes resulted in improvement in insulin resistance among those who were given CoQ10 compared with participants who received a placebo. The findings were published in the April 2026 issue of Clinical Nutrition Open Science.

"Prediabetes, defined as a state of elevated glucose levels that do not meet the diagnostic criteria for diabetes, is a nonnegligible condition," authors Pasita Palakornkitti and colleagues at Dhurakij Pundit University noted. "Not only does it pose a certain risk of developing diabetes, but it is also associated with the development of cardiovascular disease, chronic kidney disease, neuropathy and retinopathy."

The trial enrolled 20 prediabetic individuals who were between 18–60 years of age. Ten participants were given one 100-milligram capsule of ubiquinol in medium chain triglyceride oil while the remainder received a placebo daily for 12 weeks. Laboratory values, including homeostasis model assessment of insulin resistance (HOMA-IR), glucose, hemoglobin A1c and lipids, were measured at the beginning and end of the trial.

After 12 weeks, participants who received CoQ10 had significantly lower insulin resistance compared with the placebo group. No side effects were reported. Although moderate-to-large beneficial effects were found for hemoglobin A1c and fasting plasma glucose and insulin, statistical analysis did not determine the reductions to be of significance. "These findings may suggest potential metabolic benefit of ubiquinol supplementation; however, the limited sample size of this pilot study likely resulted in insufficient statistical power to detect significant differences for these outcomes," the authors commented.

"One hundred milligrams ubiquinol for 12 weeks improves insulin sensitivity for prediabetic patients with a favorable safety profile," they concluded, suggesting that the effects are worthy of investigation in larger trials.

Meta-analysis supports ability of B vitamins to lower homocysteine

February 02 2026. A systematic review and meta-analysis published January 30, 2026, in Cardiology & Cardiovascular Disorders concluded that the addition of B-vitamins to the diet is linked with a significant reduction in serum levels of homocysteine, a potentially toxic amino acid which, when elevated, has been associated with an increased risk of cardiovascular disease. "Our study aimed to determine whether multivitamin therapy offers greater homocysteine-lowering benefits than single-vitamin approaches," authors Liping Guo and colleagues explained.

For the meta-analysis, Guo and associates identified 13 randomized, controlled studies that included a total of 14,539 men and women with coronary heart disease. The studies included 7,301 control group members and 7,228 participants who were given the vitamins folate with vitamin B6 and/or B12, which regulate homocysteine metabolism. Serum total homocysteine was measured at various timepoints.

The meta-analysis showed that B-vitamin-treated individuals experienced significantly reduced serum total homocysteine compared with the control participants. No effects for the vitamins on cardiovascular events or mortality were found in this analysis.

Treated individuals also experienced a reduction in the risk of vascular restenosis: re-narrowing of a diseased artery that has been previously opened with bypass surgery or other treatments. "By lowering homocysteine levels, the treatment appears to mitigate endothelial injury and slow the progression of atherosclerosis, which is consistent with clinical observations," the authors remarked.

"Our findings highlight the synergistic role of folic acid, vitamin B6, and vitamin B12 in achieving optimal regulation of homocysteine levels.," they concluded. "Future research should focus on identifying specific subgroups (e.g. patients with severe homocysteine elevation or early-stage coronary heart disease) to further clarify its clinical value."
