This week’s research pulls no punches, from the threats in your bloodstream to the silent factors shaping future longevity. In focus: how fisetin might protect your arteries, the rising presence of microplastics inside human tissues, why your childhood diet could shape adult hormone health, and what 1.5 million people have to say about how long we live. Here’s what’s emerging from the science of ageing, and how it could help you live better now.

Fisetin and Vascular Ageing
Blood vessel calcification is a natural consequence of ageing, but one with serious implications. As calcium deposits build up in arterial walls, they reduce the elasticity of vessels, raising the risk of high blood pressure, heart attack, and stroke. While statins and lifestyle changes are commonly used to manage cardiovascular risk, new research is looking deeper into the cells that silently accelerate this decline.
Fortunately there's fisetin, a natural flavonoid found in strawberries, apples, and onions. Known for its senolytic properties, fisetin selectively clears out senescent cells, those dysfunctional, aged cells that no longer divide but refuse to die. These cells secrete inflammatory compounds that can promote tissue degeneration, including in vascular structures.
In a recent study, researchers found that fisetin supplementation reduced arterial calcification and improved endothelial function, the delicate inner lining that regulates blood vessel tone, blood flow, and immune response. The mechanism? A reduction in oxidative stress and improved vascular signalling.
Why does this matter? Because arterial stiffness isn’t just a side effect of ageing, it’s one of the primary drivers of cardiovascular disease, the number one cause of death globally.

Microplastics Found in Human Arteries
In what may be one of the most unsettling findings in recent longevity science, researchers have now identified microplastics embedded in human arteries. The study analysed arterial plaque samples and found that 60% of patients with detected microplastics had increased risk of stroke, heart attack, or death in the following three years.
The particles, ranging from polyethylene to polyvinyl chloride, are the same materials used in plastic packaging, bottles, and cosmetics. Unlike larger pollutants, microplastics are small enough to cross biological barriers, and some evidence suggests they may interfere with endothelial integrity and immune signalling.
So far, most plastic exposure research has focused on the gut microbiome. But this new data shifts attention to the vascular system, where chronic exposure may accelerate inflammation, oxidative stress, and plaque instability.
These particles aren’t just pollutants, they’re potential disruptors of cardiovascular and immune health, two pillars of ageing well. While complete avoidance is near-impossible in today’s environment, reducing single-use plastics, filtering drinking water, and choosing clean-label personal care products can reduce overall exposure.

Childhood Diet and Hormonal Ageing
While nutrition has long been linked to ageing, a new study out of China reveals a surprising new angle: your childhood diet may impact your reproductive health decades later. The study followed thousands of participants over several years and found that girls who ate more vegetables, whole grains, lean proteins, and fruits during childhood were significantly less likely to experience irregular menstrual cycles in adolescence and adulthood.
Menstrual health isn’t just about fertility, it’s a key indicator of hormonal stability, metabolic health, and inflammatory balance. Irregular cycles have been linked to higher risks of insulin resistance, mood disorders, and even cardiovascular disease later in life.
This study highlights something we often overlook: the metabolic tone set early in life echoes into adulthood, potentially shaping how our bodies respond to ageing triggers like stress, inflammation, and hormonal shifts. It also reinforces the need for inclusive, lifespan-based nutritional strategies, not just “fix-it” approaches in midlife.

Bird Flu's Rising Risk to Humans
Avian influenza (H5N1) isn’t new, but its recent behaviour has alarmed global virologists. Once restricted mostly to birds, the virus has now been detected in mammals ranging from cows to sea lions, and even humans. In several cases, infections have occurred in individuals working with livestock, raising concern about zoonotic spillover, the jump of viruses from animals to humans.
While human-to-human transmission hasn’t been confirmed, the virus is clearly evolving. This week, the World Health Organization and international researchers issued statements urging greater pandemic preparedness and surveillance infrastructure, especially in vulnerable regions where animal contact is frequent and biosecurity measures are limited.
Infectious threats don’t just affect the old, they accelerate ageing. Severe infections can shorten telomeres, inflame endothelial tissues, and impair mitochondrial function. And post-viral syndromes (like long COVID) have shown us that even a temporary illness can cause lasting dysfunction, especially in the brain.

What 1.5 Million People Tell Us About Lifespan
In a sweeping new study published this week, researchers analysed data from over 1.5 million individuals across 18 countries, tracking physical, metabolic, and psychological markers in relation to all-cause mortality.
Unsurprisingly, certain physical indicators, grip strength, walking pace, and resting heart rate, were strong predictors of lifespan. But what’s more interesting is that subjective well-being, emotional stability, and social connection also emerged as independent predictors of long-term health.
This echoes what many longevity experts have been saying: living longer is as much about stress regulation and daily rhythm as it is about lab values. People with steady sleep patterns, positive outlooks, and high-quality social support live longer, even when their physical health isn’t perfect.
The study also flagged midlife inflammation and cognitive function as major turning points. Those with persistent fatigue, brain fog, or mood instability in their 40s and 50s were more likely to experience accelerated decline—regardless of fitness level.
Which brings us to a key question: how do you keep all of these systems (brain, metabolism, mood, energy) on track in the long term?
Simply Nootropics Essentials Plus can help. With a carefully chosen blend of nootropic nutrients, including CDP-Choline for memory, L-Theanine for calm focus, and Lion’s Mane for cognitive regeneration, it’s designed to support clarity, resilience, and energy without overstimulation.
Daily stressors, from microplastics to viral exposure to cognitive fatigue, chip away at your reserves. Essentials Plus helps you replenish what modern life drains, while giving your brain the nutrients it needs to stay focused, sharp, and steady over time.
