Live Longer - Everyday Health
Spermidine, Urolithin A, NMN / NR, Vitamin D3 + K2, CoQ10, Glycine.
At Core Longevity, our Live Longer – Everyday Health category focuses on supporting the foundations of long-term health and healthy ageing. We have chosen Spermidine, Urolithin A, NMN or NR, Vitamin D3 + K2, CoQ10 and Glycine because each represents a different area of interest within modern longevity and healthy-ageing research.
Importantly, we do not believe that any supplement can guarantee a longer life. Instead, we focus on supplements that may support biological processes associated with healthspan — helping us stay healthier, stronger and more capable as we age.
Together, these supplements cover a range of areas, including cellular maintenance, mitochondrial health, energy production and everyday health foundations. We have deliberately combined emerging longevity ingredients with more established nutrients to create a balanced approach.
As with every product we review, we apply the Core Longevity principles of Quality, Purity and Purpose. We look for clearly identified ingredients, transparent formulations, evidence of quality testing where available and products without unnecessary fillers, additives or added sugars.
At Core Longevity, we believe living longer should also mean living better. These supplements have been chosen not as replacements for a healthy lifestyle, but as potential tools that may support the long-term foundations of health alongside good nutrition, regular exercise, quality sleep and other healthy lifestyle habits.
Below, we explore why each of these supplements is worth considering within our Live Longer – Everyday Health category and what we look for when selecting our Top 3 products.

Why Spermidine?
At Core Longevity, we chose Spermidine because it is one of the most interesting and increasingly researched compounds in modern longevity and healthy-ageing science.
Spermidine is a naturally occurring compound found within the body and in foods such as wheat germ, mushrooms and certain fermented foods. It has attracted particular scientific interest because of its potential role in supporting autophagy — a natural cellular process involved in breaking down and recycling damaged or unnecessary cellular components.
As we age, the efficiency of some cellular maintenance processes may change or decline. This is one reason spermidine has become an area of growing interest within healthy-ageing research. Scientists are continuing to study whether supporting these natural processes could contribute to long-term cellular health and function.
For Core Longevity, Spermidine represents an exciting addition to our Live Longer – Everyday Health category because it focuses on a fundamental aspect of healthy ageing: supporting the body's natural cellular maintenance and recycling processes.
While the research is still developing and no supplement can guarantee a longer life, Spermidine's connection to cellular health and its growing scientific interest make it a particularly interesting ingredient to explore as part of the wider conversation around healthspan and healthy ageing.

Why Urolithin A?
At Core Longevity, we chose Urolithin A because it is one of the most exciting emerging compounds in modern longevity and healthy-ageing research.
Urolithin A is a compound that can be produced when certain gut bacteria break down dietary compounds found in foods such as pomegranates, berries and walnuts. However, the ability to produce Urolithin A varies considerably between individuals, which is one reason direct supplementation has attracted growing scientific interest.
Urolithin A is being studied for its potential role in mitophagy — a natural cellular process involved in identifying and recycling damaged or ageing mitochondria. Mitochondria play a central role in cellular energy production, making mitochondrial health particularly relevant to maintaining physical function, muscle health and overall cellular function as we age.
For Core Longevity, Urolithin A represents an exciting addition to our Live Longer – Everyday Health category because it focuses on a fundamental area of healthy ageing: supporting mitochondrial health and the body's natural cellular maintenance processes.
While research is still developing and Urolithin A cannot be said to make people live longer, its growing scientific interest and potential connection to mitochondrial function, cellular energy and healthy ageing make it a particularly interesting supplement to explore.

Why NMN / NR?
At Core Longevity, we chose NMN and NR because they are among the most widely discussed compounds in modern longevity and healthy-ageing research.
Both NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are involved in the body's production of NAD+, a molecule naturally present in our cells that plays an important role in cellular energy metabolism and a wide range of biological processes.
NAD+ levels are known to change with age, which has made NMN and NR an important area of interest within longevity research. Scientists are continuing to study whether supporting NAD+ levels could help maintain healthy cellular energy metabolism and other processes associated with healthy ageing.
For Core Longevity, NMN and NR represent an exciting part of our Live Longer – Everyday Health category because they focus on a fundamental aspect of long-term health: supporting cellular processes involved in how our bodies produce and use energy.
While research is still developing, and neither NMN nor NR can currently be said to extend human lifespan, their growing scientific interest and connection to NAD+, cellular energy and metabolism make them particularly interesting compounds to explore within the wider field of healthy ageing.

Why Vitamin D3 + K2?
At Core Longevity, we chose Vitamin D3 + K2 because long-term health is not only about the latest longevity compounds — it is also about supporting the essential foundations that help our bodies function well as we age.
Vitamin D3 plays an important role in supporting normal immune function, muscle function and the maintenance of healthy bones and teeth. It also contributes to the normal absorption and utilisation of calcium. Vitamin K2, a form of vitamin K, contributes to normal blood clotting and the maintenance of normal bones.
For Core Longevity, the combination is particularly interesting because Vitamin D and Vitamin K contribute to different but complementary aspects of everyday health. Vitamin D supports the body's normal absorption and use of calcium, while vitamin K contributes to maintaining normal bones.
We included Vitamin D3 + K2 in our Live Longer – Everyday Health category because maintaining strong bones, healthy muscles and normal immune function can become increasingly important as we age. Supporting these foundations can help us focus not simply on living longer, but on maintaining the strength, health and independence needed to live well for longer.
While Vitamin D3 + K2 cannot be said to extend human lifespan, it represents a practical and well-established approach to supporting important aspects of everyday health and healthy ageing.

Why CoQ10?
At Core Longevity, we chose CoQ10 because it plays an important role in one of the body's most fundamental processes: cellular energy production.
CoQ10 is a naturally occurring compound found throughout the body, where it is involved in the processes cells use to produce energy. It is particularly concentrated in tissues and organs with high energy demands, including the heart, muscles and brain.
As we age, CoQ10 levels can change, which is one reason it has become an area of interest within healthy-ageing research. CoQ10 also has an important role as an antioxidant, helping to protect cells from oxidative stress.
For Core Longevity, CoQ10 fits naturally within our Live Longer – Everyday Health category because supporting normal cellular energy production is an important part of maintaining overall health as we age. Rather than being focused purely on short-term performance, CoQ10 is associated with one of the body's most fundamental cellular processes.
While CoQ10 cannot be said to extend human lifespan, its important role in cellular energy production and antioxidant protection makes it a particularly interesting supplement to explore within the wider context of healthy ageing.

Why Glycine?
At Core Longevity, we chose Glycine because sometimes the simplest nutrients can be just as interesting as the latest longevity trends.
Glycine is a naturally occurring amino acid involved in several important processes throughout the body. It contributes to the production of proteins and collagen and plays a role in processes involved in antioxidant defence and normal metabolism.
It has attracted growing scientific interest within healthy-ageing research because glycine is involved in fundamental biological processes rather than targeting just one specific area of health.
For Core Longevity, Glycine is a particularly strong fit because it is often available in pure, single-ingredient formulations, without added sugars, flavourings, sweeteners or unnecessary fillers. This makes it an excellent match for our principles of Quality, Purity and Purpose.
We included Glycine in our Live Longer – Everyday Health category because supporting the body's fundamental biological processes is an important part of taking a long-term approach to health. While glycine cannot be said to extend human lifespan, its simplicity, affordability and growing scientific interest make it a particularly interesting supplement to explore.
